Dali is a graphics program for the Atari ST.
SD0 files are 320x200 with 16 colors
SD1 files are 640x200 with 4 colors
SD2 files are 640x400 in mono
Format details
Dali file format
Copied from Atari Forum Wiki.
Dali *.SD0 (ST low resolution)
*.SD1 (ST medium resolution)
*.SD2 (ST high resolution)
Files do not seem to have any resolution or bit plane info stored in them. The file
extension seems to be the only way to determine the contents.
1 long file id? [always 0]
16 words palette
92 bytes reserved? [usually 0]
32000 bytes raw image data
-----------
32128 bytes total for file
Dali Compressed file format
Copied from Atari Forum Wiki.
Dali compressed *.LPK (ST low resolution)
*.MPK (ST medium resolution)
*.HPK (ST high resolution)

? image data:
Assuming the tables have been loaded into arrays:

uint32 *ltab=malloc(size of long array);
uint8 *bmap=malloc(32000); /* st bitmap */
