Color format

2023-08-29T08:13:37Z

Foxtrot:

A '''color format''', not to be confused with [[Color profiles]] or [[Graphics|Graphics formats]], describe the way in which data is stored within an image and specifically concerns the way that data is loaded by dedicated graphics hardware. The concept of a '''color format''' has an inconsistent nomenclature, often referred to as ''Pixel'', ''Texture'', ''Image'', or ''Graphics'' formats. In [[Direct3D]], these are known as ''Surface Formats''.

Often, dedicated graphics hardware has a fixed range of supported '''color formats''', chosen to meet both industry needs of those which integrate with the hardware and whatever will offer the best performance or stability on said hardware.

A color format is broken down into the number of bits reserved for each color, and the order of those bits, i.e. ''R8G8B8''. As color formats concern graphics hardware, they often specify the ''red'', ''blue'', ''green'' and ''alpha'' channels. Although, some formats exist for other graphics purposes, such as ''normal maps'' or ''depth maps''.

The more bits which are allocated, the more potential colors can be reproduced with that format. However, this comes at the cost of size. As humans are more sensitive to changes in luminance than colour, and more sensitive to certain wave-lengths of light, some formats specifically under-allocate bits to certain channels as a compromise between visual fidelity and size.

Whilst there is no standardisation of the letters when describing a format, the following are commonly used:

{| class="wikitable"
! Letter
! Purpose
|-
| R
| ''Red''
|-
| G
| ''Green'' (or ''Grey'')
|-
| B
| ''Blue''
|-
| A
| ''Alpha''
|-
|-
| L
| ''Luminance''
|-
| U, V, W & Q
| Bump or normal data
|-
| P
| Palette index (i.e. a ''P8'' denotes a palette of 256 colors)
|-
| X
| Padding bits (ignored but kept for alignment)
|}

== Example ==

The most simplest color format is '''R8G8B8''', signifying that 8-bits (a [[byte]]) are reserved for the ''red'', ''blue'', ''green'' channels, respectively. Totalling 24-bits per pixel. This allows each channel to range between 0-255 values, for a total of over 16 million potential colours.

By comparison, the '''A8B8G8R8''' is similar to above, with an additional 8-bits for alpha information — totalling 32-bits per pixel. Whether the alpha is expected to be ''premultiplied'' or ''straight'' is determined by the hardware.

== R5G6B5 ==

'''R5G6B5''' was a common format for early 3D game consoles. Which allowed 5-bits for ''red'' and ''blue'', and 6-bits for ''green''. The additional ''green'' bits were owed to the human eye's higher-sensitivity to green light.

Foxtrot:

A '''color format''', not to be confused with [[Color profiles]] or [[Graphics|Graphics formats]], describe the way in which data is stored within an image and specifically concerns the way that data is loaded by dedicated graphics hardware. The concept of a '''color format''' has an inconsistent nomenclature, often referred to as ''Pixel'', ''Texture'', ''Image'', or ''Graphics'' formats. In [[Direct3D]], these are known as ''Surface Formats''.

Often, dedicated graphics hardware has a fixed range of supported '''color formats''', chosen to meet both industry needs of those which integrate with the hardware and whatever will offer the best performance or stability on said hardware.

A color format is broken down into the number of bits reserved for each color, and the order of those bits, i.e. ''R8G8B8''. As color formats concern graphics hardware, they often specify the ''red'', ''blue'', ''green'' and ''alpha'' channels. Although, some formats exist for other graphics purposes, such as ''normal maps'' or ''depth maps''.

The more bits which are allocated, the more potential colors can be reproduced with that format. However, this comes at the cost of size. As humans are more sensitive to changes in luminance than colour, and more sensitive to certain wave-lengths of light, some formats specifically under-allocate bits to certain channels as a compromise between visual fidelity and size.

Whilst there is no standardisation of the letters when describing a format, the following are commonly used:

{| class="wikitable"
! Letter
! Purpose
|-
| R
| ''Red''
|-
| G
| ''Green'' (or ''Grey'')
|-
| B
| ''Blue''
|-
| A
| ''Alpha''
|-
|-
| L
| ''Luminance''
|-
| U, V, W & Q
| Bump or normal data
|-
| P
| Palette index (i.e. a ''P8'' denotes a palette of 256 colors)
|-
| X
| Padding bits (ignored but kept for alignment)
|}

== Example ==

The most simplest color format is '''R8G8B8''', signifying that 8-bits (a [[byte]]) are reserved for the ''red'', ''blue'', ''green'' channels, respectively. Totalling 24-bits per pixel. This allows each channel to range between 0-255 values, for a total of over 16 million potential colours.

By comparison, the '''A8B8G8R8''' is similar to above, with an additional 8-bits for alpha information — totalling 32-bits per pixel. Whether the alpha is expected to be ''premultiplied'' or ''straight'' is determined by the hardware.

The '''.TMD''' file format is the standard file format for 3D objects on PlayStation. It is also used by many PC ports of Playstation games, like Resident Evil, Resident Evil 2, Resident Evil 3.

== Structure ==

The values are stored in Little-Endian order.

=== Header ===

A TMD file can contain several 3D models. It starts with this header:

<pre>typedef struct {
unsigned long id; /* Constant = 0x41 */
unsigned long unknown;
unsigned long num_objects; /* Number of objects in file */
} tmd_header_t;</pre>

Then are following the objects headers, as an array of tmd_object_t objects[num_objects].

Vertices and normals share the same format to holds the 3D coordinate:

<pre>typedef struct {

short y;
short z;

=== Primitives ===

Each primitive starts with same header, and the rest depend on the primitive type:

unsigned char unknown1;
unsigned char type; /* primitive type */

The values are stored in Little-Endian order.

=== Header ===

A TMD file can contain several 3D models. It starts with this header:

<pre>typedef struct {
unsigned long id; /* Constant = 0x41 */
unsigned long unknown;
unsigned long num_objects; /* Number of objects in file */
} tmd_header_t;</pre>

Then are following the objects headers, as an array of tmd_object_t objects[num_objects].

=== Object ===

<pre>typedef struct {
unsigned long vertex_offset; /* Offset to vertex array coordinates */
unsigned long vertex_count; /* Number of vertices */
unsigned long normal_offset; /* Offset to normal array coordinates */
unsigned long normal_count; /* Number of normals */
unsigned long primitive_offset; /* Offsets to primitives */
unsigned long primitive_count; /* Number of primitives */
unsigned long unknown;
} tmd_object_t;</pre>

=== Vertex, normal ===

Vertices and normals share the same format to holds the 3D coordinate:

<pre>typedef struct {
short x;
short y;
short z;
short zero;
} tmd_vertex_t;

=== Primitives ===

Each primitive starts with same header, and the rest depend on the primitive type:

<pre>typedef struct {
unsigned char unknown0;
unsigned char length; /* Length of following primitive in 32bit words */
unsigned char unknown1;
unsigned char type; /* primitive type */
} tmd_prim_header_t;</pre>

=== Single color triangle (type 0x20,0x22) ===

<pre>typedef struct {
unsigned char r,g,b,unknown; /* R,G,B triangle color */

unsigned short n0; /* Normal index */

unsigned short v0; /* Vertex index */
unsigned short v1;
unsigned short v2;
} tmd_flattriangle_t;</pre>

=== Gouraud triangle (type 0x24) ===

<pre>typedef struct {
unsigned char r0,g0,b0,unk0; /* R,G,B vertex color */
unsigned char r1,g1,b1,unk1;
unsigned char r2,g2,b2,unk2;

unsigned short n0; /* Normal index */

unsigned short v0; /* Vertex index */
unsigned short v1;
unsigned short v2;
} tmd_gouraudtriangle_t;</pre>

=== Single color quad (type 0x28) ===

<pre>typedef struct {
unsigned char r,g,b,unknown; /* R,G,B quad color */

unsigned short n0; /* Normal index */

unsigned short v0; /* Vertex index */
unsigned short v1;
unsigned short v2;
unsigned short v3;
} tmd_flatquad_t;

=== Gouraud quad (type 0x2c) ===

<pre>typedef struct {
unsigned char r0,g0,b0,unk0; /* R,G,B vertex color */
unsigned char r1,g1,b1,unk1;
unsigned char r2,g2,b2,unk2;
unsigned char r3,g3,b3,unk3;

unsigned short n0; /* Normal index */

unsigned short v0; /* Vertex index */
unsigned short v1;
unsigned short v2;
unsigned short v3;

unsigned short unk5;
} tmd_gouraudquad_t;</pre>

=== Flat triangle with vertex normals (type 0x30) ===

<pre>typedef struct {
unsigned char r,g,b,unk; /* R,G,B triangle color */

unsigned short n0; /* Normal index */
unsigned short v0; /* Vertex index */
unsigned short n1;
unsigned short v1;
unsigned short n2;
unsigned short v2;
} tmd_flattriangle2_t;</pre>

=== Textured triangle (type 0x34) ===

<pre>typedef struct {
unsigned short unknown1;
unsigned char v0; /* textures coordinates */
unsigned char u0;
unsigned short unknown2;
unsigned char v1;
unsigned char u1;
unsigned short unknown3;
unsigned char v2;
unsigned char u2;

unsigned short v0; /* Vertex index */
unsigned short n0; /* Normal index */
unsigned short v1;
unsigned short n1;
unsigned short v2;
unsigned short n2;
} tmd_txtriangle_t;</pre>

=== Flat quad with vertex normals (type 0x38) ===

<pre>typedef struct {
unsigned char r,g,b,unk; /* R,G,B quad color */

unsigned short n0; /* Normal index */
unsigned short v0; /* Vertex index */
unsigned short n1;
unsigned short v1;
unsigned short n2;
unsigned short v2;
unsigned short n3;
unsigned short v3;
} tmd_flatquad2_t;</pre>

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

==== Camera masks (*.PRI) ====

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;</pre>

If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */

=== Offset 10 (*.EDD) - Skeleton animation steps ===

See File/Section 1 of [[EMD (Resident Evil 1997)]].

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

[[Category:Resident Evil (1997)]]

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

{| class="wikitable"
! Offset

|-
! 0
| Camera switches (*.RVD)
|-
! 1

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

==== Camera masks (*.PRI) ====

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;</pre>

If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 10 (*.EDD) - Skeleton animation steps ===

See File/Section 1 of .EMD_(Resident_Evil)

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

{{Restored|2016-08-09|https://web.archive.org/web/20160809012215/http://rewiki.regengedanken.de/wiki/.EMD_(Resident_Evil)}}

The '''.EMD''' file format is used by Resident Evil. It contains the description of 3D models of the game (enemies, player, etc...).

== Structure ==

The values are stored in Little-Endian order.

=== Directory ===

There is a directory, which is stored at the end of the file, it contains 4 offsets. So its position is filesize-4*4 bytes.

=== File/Section 0, skeleton ===

This section starts with a header:

<pre>
typedef struct {
unsigned short relpos_offset;/* Relative offset to emd1_skel_relpos[] array */
unsigned short length; /* Relative offset to emd1_skel_data[] array, which is also length of relpos+armature+mesh numbers */
unsigned short count; /* Number of objects in relpos,data2,mesh arrays? */
unsigned short size; /* Size of each element in emd1_skel_data[] array */
} emd1_skel_header_t;
</pre>

If offset is more than 8, there are some extra stuff, namely data1,data2 and mesh arrays.

<pre>
typedef struct {
short x;
short y;
short z;
} emd1_skel_relpos_t; /* Relative position of each mesh in the object */

typedef struct {
unsigned short mesh_count; /* Number of meshes linked to this one */
unsigned short offset; /* Relative offset to mesh numbers (emd1_skel_mesh[] array) */
} emd1_skel_armature_t;

emd1_skel_relpos_t emd1_skel_relpos[count];
emd1_skel_armature_t emd1_skel_armature[count];
unsigned char emd1_skel_mesh[count]; /* Mesh number on which to apply relative position */
</pre>

Finally an array of elements which have a size of emd1_skel_header.size bytes each.

<pre>
typedef struct {
short x_offset; /* distance from reference point */
short y_offset;
short z_offset;

short x_speed; /* speed at which moving the model */
short y_speed;
short z_speed;

short angles[3*15]; /* angle for each bone/model around x,y,z axis */

short unknown;
} emd1_skel_anim_t;

emd1_skel_anim_t emd1_skel_anim[];
</pre>

=== File/Section 1, animation steps ===

This section starts with this header, a certain number of records composed of count and offsets.

<pre>typedef struct {
unsigned short count; /* Count of indices to process from emd_sec1_data[] array */
unsigned short offset; /* Byte offset to first index in emd_sec1_data[] array */
} emd_anim_header_t;

emd_anim_header_t emd_anim_header[];</pre>

Following this array, you'll find another array of unsigned long. Each value (animation frame number?) is an index in emd_sec2_data array in the skeleton section.

<pre>unsigned long emd_anim_skel_t[]; /* Bits 31-16: Bitmasks for flags */
/* Bits 15-0: Number of frame to display ? */
</pre>

Then you'll finally find the 'unsigned long' byte length of the section.

<pre>unsigned long length;</pre>

=== File/Section 2, meshes ===

The last object holds the 3D stuff. Maybe the rest of the file is use to store animations, and links between primitives.

==== Header ====

<pre>typedef struct {
unsigned long length; /* Section length in bytes */
unsigned long unknown;
unsigned long obj_count; /* Number of objects in model */
} emd_model_header_t;
</pre>

The model is separated in 'obj_count' objects. Following the header is the description of each object, in the form of an array of 'model_object'. Each offset is relative to the first emd_model_object_t.

<pre>typedef struct {
emd_model_triangles_t triangles;
} emd_model_object_t;

typedef struct {
unsigned long vertex_offset; /* Offset to vertex data, array of emd_vertex_t */
unsigned long vertex_count; /* Vertex count */
unsigned long normal_offset; /* Offset to normal data, array of emd_vertex_t */
unsigned long normal_count; /* Normal count */
unsigned long tri_offset; /* Offset to triangle data, array of emd_triangle_t */
unsigned long tri_count; /* Triangle count */
unsigned long dummy;
} emd_model_triangles_t;
</pre>

==== Index arrays ====

Normal and vertex coordinates are saved in same format:

<pre>typedef struct {
signed short x; /* Coordinates */
signed short y;
signed short z;
signed short zero;
} emd_vertex_t; /* Normals have same format */
</pre>

A triangle is stored in this format:

<pre>typedef struct {
unsigned long unknown; /* id 0x34000609 */

unsigned char tu0; /* u,v texture coordinates of vertex 0 */
unsigned char tv0;
unsigned short clutid; /* Texture clut id, bits 0-5 */
unsigned char tu1;
unsigned char tv1;
unsigned short page; /* Texture page */
unsigned char tu2;
unsigned char tv2;
unsigned short dummy;

unsigned short n0; /* Index of normal data for vertex 0 */
unsigned short v0; /* Index of vertex data for vertex 0 */
unsigned short n1;
unsigned short v1;
unsigned short n2;
unsigned short v2;
} emd_triangle_t; /* Triangle */</pre>

=== File/Section 3, texture ===

And finally, an embedded [[TIM (PlayStation graphics)|TIM image]], which is the texture to apply to the model.

[[Category:Resident Evil (1997)]]

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

==== Camera masks (*.PRI) ====

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;</pre>

If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 7 (*.SCD) - Execution script for room ===

This script is run regularly to update stuff in current room. It follows same structure as the one at offset 6.

=== Offset 8, Script events ? ===

This structure starts with a NULL terminated list of [[unsigned long]], which are offsets relative to start of this object. These offsets store also some bytecodes, different than those above.

=== Offset 10 (*.EDD) - Skeleton animation steps ===

See File/Section 1 of .EMD_(Resident_Evil)

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

RDT (Resident Evil 1997)

Foxtrot: /* Camera masks (*.PRI) */

{{FormatInfo
|formattype=electronic
|extensions={{ext|rdt}}
}}

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

==== Camera masks (*.PRI) ====

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;</pre>

If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 7 (*.SCD) - Execution script for room ===

This script is run regularly to update stuff in current room. It follows same structure as the one at offset 6.

=== Offset 8, Script events ? ===

This structure starts with a NULL terminated list of [[unsigned long]], which are offsets relative to start of this object. These offsets store also some bytecodes, different than those above.

=== Offset 10 (*.EDD) - Skeleton animation steps ===

See File/Section 1 of .EMD_(Resident_Evil)

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

Foxtrot: /* Offset 0 (*.RVD) - Camera zones/switches */

{{FormatInfo
|formattype=electronic
|extensions={{ext|rdt}}
}}

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

=== Camera masks (*.PRI) ===

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;</pre>

If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

=== Camera masks (*.PRI) ===

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;
If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 10 (*.EDD) - Skeleton animation steps ===

See File/Section 1 of .EMD_(Resident_Evil)

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

{{FormatInfo
|formattype=electronic
|extensions={{ext|rdt}}
}}

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

=== Camera masks (*.PRI) ===

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;
If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

This script is run regularly to update stuff in current room. It follows same structure as the one at offset 6.

=== Offset 8, Script events ? ===

This structure starts with a NULL terminated list of [[unsigned long]], which are offsets relative to start of this object. These offsets store also some bytecodes, different than those above.

=== Offset 10 (*.EDD) - Skeleton animation steps ===

See File/Section 1 of .EMD_(Resident_Evil)

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

{{FormatInfo
|formattype=electronic
|extensions={{ext|rdt}}
}}

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

=== Camera masks (*.PRI) ===

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;
If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 9 (*.EMR) - Skeleton animation ===

See File/Section 0 of .EMD_(Resident_Evil)

=== Offset 10 (*.EDD) - Skeleton animation steps ===

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

{{FormatInfo

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

=== Camera masks (*.PRI) ===

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;
If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */

=== Offset 9 (*.EMR) - Skeleton animation ===

=== Offset 10 (*.EDD) - Skeleton animation steps ===

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of [[unsigned short]], which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

{{FormatInfo

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

=== Camera masks (*.PRI) ===

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;
If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */

unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 9 (*.EMR) - Skeleton animation ===

=== Offset 10 (*.EDD) - Skeleton animation steps ===

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of 'unsigned short', which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

Conversion table, from byte to ASCII value:

<pre>
0x00-0x0f: " .___()_____0123"
0x10-0x1f: "456789:_,"!?_ABC"
0x20-0x2f: "DEFGHIJKLMNOPQRS"
0x30-0x3f: "TUVWXYZ[/]'-_abc"
0x40-0x4f: "defghijklmnopqrs"
0x50-0x5f: "tuvwxyz_________"

Note: not all characters have been found (i.e. the ones with '_').
Codes above 0x57 may also be different given the language, for characters with trema, accents and the like.
There are also some formatting codes:

0x01: End of text
0x02: Carriage return
0x03: Pause
0x08: Yes/No question
0x74: "S." string
0x75: "T." string

RDT (Resident Evil 1997)

Foxtrot: /* Offset 6 (*.SCD) - Scenario data */

{{FormatInfo
|formattype=electronic
|extensions={{ext|rdt}}
}}

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

=== Camera masks (*.PRI) ===

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;
If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 9 (*.EMR) - Skeleton animation ===

=== Offset 10 (*.EDD) - Skeleton animation steps ===

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of 'unsigned short', which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

Conversion table, from byte to ASCII value:

<pre>
0x00-0x0f: " .___()_____0123"
0x10-0x1f: "456789:_,"!?_ABC"
0x20-0x2f: "DEFGHIJKLMNOPQRS"
0x30-0x3f: "TUVWXYZ[/]'-_abc"
0x40-0x4f: "defghijklmnopqrs"
0x50-0x5f: "tuvwxyz_________"

Note: not all characters have been found (i.e. the ones with '_').
Codes above 0x57 may also be different given the language, for characters with trema, accents and the like.
There are also some formatting codes:

0x01: End of text
0x02: Carriage return
0x03: Pause
0x08: Yes/No question
0x74: "S." string
0x75: "T." string

Foxtrot: /* Offset 6 (*.SCD) - Scenario data */

{{FormatInfo
|formattype=electronic
|extensions={{ext|rdt}}
}}

{{Restored|2017-11-25|https://web.archive.org/web/20171125230810/http://rewiki.regengedanken.de/wiki/.RDT_(Resident_Evil)}}

The '''.RDT''' file format is used to stored the description of a room in Resident Evil on Playstation or PC. It should contain the camera position (to correctly display 3D objects), the background images and sprites used to draw the scene, description of when to change camera, position of enemies when entering room, and so on...

== Structure ==

The values are stored in Little-Endian order.

The file is always named <code>roomSXX0.rdt</code> (or <code>roomSXX1.rdt</code>). <code>S</code> is the game status/stage. <code>XX</code> is the location number.

== Header ==

A RDT file starts with this header, to store count for different objects.

<pre>
typedef struct {
char unknown0;
char num_cameras; /* Number of cameras of the room */
char num_sound_banks; /* Number of sound banks, stored at offset 18 ? */
char unknown1[3];
unsigned short unknown2[3];

/* An array of 3 elements of unknown structure */
rdt_header_part_t unknown3[3];
} rdt_header_t;

<pre>
typedef struct {
long unknown_pos_x; /* Unknown 3D position */
long unknown_pos_y;
long unknown_pos_z;
unsigned long unknown0[2];
} rdt_header_part_t;
</pre>

== Object list ==

Following the header, we have an array of 19 absolute offsets to various objects in the file.

=== Camera positions (*.RID) ===

At absolute offset 0x94 in a file, you'll find an array of 'num_cameras' items with this structure:

<pre>
typedef struct {
long masks_offset; /* Offset to image mask definition */
long tim_masks_offset; /* Offset to TIM file that contains image masks, if not zero */
long camera_from_x; /* Position of the camera */
long camera_from_y;
long camera_from_z;
long camera_to_x; /* Where the camera is looking to */
long camera_to_y;
long camera_to_z;
long unknown1[3];
} rdt_camera_t;
</pre>

=== Camera masks (*.PRI) ===

The masks_offset is an offset to an extra structure, which has following header:

<pre>
typedef struct {
unsigned short count_offsets; /* Number of global offsets, or 0xffff for none */
unsigned short unknown;
} rdt_masks_t;
</pre>

Then you have 'rdt_mask_offset_t' items, which have a 8-byte length. Summing all 'count' fields should equal the 'count_masks' of the rdt_masks_t structure.

<pre>
typedef struct {
unsigned short count; /* Number of masks, with which to use this structure */
unsigned short unknown;
unsigned short dst_x; /* Destination position on background image/screen, to be added */
unsigned short dst_y;
} rdt_mask_offset_t;
</pre>

And then you have 'rdt_[rect|square]_mask_t' items, which have either 12-byte (rectangular mask) or 8-byte length (square mask). The length is 12 if byte 7 (rdt_square_mask_t.size field) is zero, and 8 otherwise. The 'depth' value is the Z distance of the mask from the camera (low value=near, high value=far).

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned char unknown;
unsigned char size; /* Width and height of mask */
} rdt_square_mask_t;
</pre>

<pre>
typedef struct {
unsigned char src_x; /* Source position in horr/usa/objspr/ospSSRRC.pak image file */
unsigned char src_y;
unsigned char dst_x; /* Destination position on background image/screen */
unsigned char dst_y;
unsigned short depth; /* Distance/16 from camera */
unsigned short zero;
unsigned short width, height; /* Dimensions of mask */
} rdt_rect_mask_t;
</pre>

=== Offset 0 (*.RVD) - Camera zones/switches ===

At offset 0, you'll find the list of camera switches for the current room. The list end with the first 4 bytes are 0xffffffff (i.e for cam0 and cam1 values).

<pre>
typedef struct {
unsigned short to; /* Camera number to switch to */
unsigned short from; /* Camera number to switch from */
short x1,y1; /* Zone the player must enter to switch camera */
short x2,y2;
short x3,y3;
short x4,y4;
} rdt_camera_switch_t;
If the 'to' value = 9, then it is a zone, defining the area in which the switches will work and 3D objects will be visible while this camera is used, else it is a camera switch.

=== Offset 1 (*.SCA) - Collision Boundaries for 3D Models ===

At offset 1, you'll find the boundary collision data for the current room.

The first 24 bytes are the header which is using the following structure:

<pre>
typedef struct {
unsigned short Cx; /* Ceiling x value */
unsigned short Cz; /* Ceiling z value */
unsigned long counts[5]; /* Number of objects = sum of these 5 long values */
} rdt_sca_header_t;</pre>

Followed by the header, the individual boundary entries start.

<pre>
typedef struct {
unsigned short x1; /* X of the top-left corner of the boundary plane/object */
unsigned short z1; /* Z of the top-left corner of the boundary plane/object */
unsigned short x2; /* X of the bottom-right corner of the boundary plane/object */
unsigned short z2; /* Z of the bottom-right corner of the boundary plane/object */
unsigned short type; /* type of the boundary plane/object (01=Standard; 03=Circle etc.) */
unsigned short floor; /* floor value/ 256 = floor value for use in the game as height definition */
} rdt_sca_obj_t;</pre>

After this the data block ends with a 4 byte unsigned long holding the total size of the SCA data block in bytes.

=== Offset 2 (*.TMD/*.TIM) - Item 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset2_t;</pre>

=== Offset 3 (*.TMD/*.TIM) - Room 3D model & texture pointers ===

This is an array of N structures of the following format, used by script instruction OM_SET (0x1f).

<pre>
typedef struct {
unsigned long tmd_offset;
unsigned long tim_offset;
} rdt_offset3_t;
</pre>

=== Offset 4 (*.BLK) - Block data ===

It's unknown what this data is used for. It defines plane based areas that look like "inversed" collision boundaries.

<pre>
unsigned short int Amount; /* Amount of elements */

typedef struct {
unsigned short x1; /* X of the top-left corner of the object */
unsigned short z1; /* Z of the top-left corner of the object */
unsigned short x2; /* X of the bottom-right corner of the object */
unsigned short z2; /* Z of the bottom-right corner of the object */
unsigned short int Dir_bit;
unsigned short int Abut;
} rdt_blk_obj_t;

unsigned short int unknown; /* unknown; follows after last structure */

rdt_blk_obj_t Block[Amount];
</pre>

=== Offset 5 (*.FLR) - Floor/footstep sound areas ===

This data defines the footstep sound areas and which sound to use. It is also related to the script opcode, 'Flr_set'.

<pre>
unsigned short int Amount; /* Amount of elements */
typedef struct {
signed short int x; /* x coordinate where the area is drawn from */
signed short int y; /* y coordinate where the area is drawn from */
signed short int x_width; /* x width of the area */
signed short int y_width; /* y width of the area */
unsigned short int sound; /* footstep ID sound to use */
} rdt_flr_obj_t;

rdt_flr_obj_t Floor[Amount];
</pre>

=== Offset 6 (*.SCD) - Scenario data ===

This is the initialisation script for the room. It starts with an unsigned short giving the length of the script in bytes. Then follows the script, in bytecode-style.

=== Offset 7 (*.SCD) - Execution script for room ===

This script is run regularly to update stuff in current room. It follows same structure as the one at offset 6.

=== Offset 8, Script events ? ===

This structure starts with a NULL terminated list of [[unsigned long]], which are offsets relative to start of this object. These offsets store also some bytecodes, different than those above.

=== Offset 9 (*.EMR) - Skeleton animation ===

=== Offset 10 (*.EDD) - Skeleton animation steps ===

=== Offset 11 (*.MSG) - Text messages ===

First, you have an arrays of 'unsigned short', which are relative offsets to the beginning of this object. So the number of items is the first offset/2 (if we are lucky that the first offset always has the lowest value).

It contains the texts for cutscenes, dialogs, examining objects.

Conversion table, from byte to ASCII value:

<pre>
0x00-0x0f: " .___()_____0123"
0x10-0x1f: "456789:_,"!?_ABC"
0x20-0x2f: "DEFGHIJKLMNOPQRS"
0x30-0x3f: "TUVWXYZ[/]'-_abc"
0x40-0x4f: "defghijklmnopqrs"
0x50-0x5f: "tuvwxyz_________"

Note: not all characters have been found (i.e. the ones with '_').
Codes above 0x57 may also be different given the language, for characters with trema, accents and the like.
There are also some formatting codes:

0x01: End of text
0x02: Carriage return
0x03: Pause
0x08: Yes/No question
0x74: "S." string
0x75: "T." string
0x76: "A." string
0x77: "R." string
0x79: ". " string
