'''Cartrivision''' was an early (1972) attempt at home video, consisting of a combination TV and video tape player that was designed to play rented movies in a proprietary cassette format. Notably, the consumer devices were incapable of rewinding the tapes, enforcing that rented movies only be played once and could only be rewound at the store from which they were rented. There was also an alternate Cartrivision cassette format that could be rewound, used in purchasable tapes, which could be played on the same players but with rewinding enabled. The rewindable cassettes were black, while the non-rewindable ones were red.

Cassettes were 7 inches by 6.5 inches by 1.5 inches, and contained two reels of half inch magnetic tape mounted on top of one another. Recording capacity was 114 minutes. The recording method was based on [https://patents.google.com/patent/US3718755 US Patent 3,718,755], an improvement over that of [https://patents.google.com/patent/US3359365 US Patent 3,359,365].

'''Pack Magic''' is a compression utility for DOS, developed by Parsons Technology of Cedar Rapids, Iowa. Parsons Technology was founded by Bob Parsons, better known as the founder of GoDaddy.

It has two main features:
* [[Executable compression]]
* Archiving all the files in a directory (then deleting them)

For executable compression, it uses a version of [[AXE (executable compression)|AXE by SEA]]. This article only covers the directory archive format, which is presumably native to Pack Magic.

== Discussion ==
A directory is archived to a pair of files named MAGIC.PCK and MAGIC.LOC. The LOC file contains only the directory's original name and location.

Ed. note: No luck getting Pack Magic to run in [[DOSBox]] or [[DOSBox-X]]. Success with [[86Box]] and MS-DOS 6.22.

== Identification ==
At least some PCK files start with bytes {{magic|40 e2 01 00}}. This is based on minimal testing, and information from [[IDArc]].

The LOC file is just a short text file, which can't be identified.

== Software ==

GoatTracker module

{{FormatInfo
|formattype=electronic
|subcat=Audio and Music
|extensions={{ext|sng}}
|wikidata={{wikidata|Q105852999}}
}}

'''<code>.sng</code>''' is the native project file format used by '''GoatTracker''', a popular cross-platform music tracker designed to compose music for the Commodore 64 SID (Sound Interface Device) chip.

The format stores the compositional data (patterns, instrument parameters, and sequence orders) rather than actual audio waveforms. It is intended to be opened and edited within the GoatTracker software, as opposed to the compiled [[SID (audio format)|.sid]] format which is used for playback.

== Software ==
* [[GoatTracker]]

== Description ==
The <code>.sng</code> format is a binary file format. It is structured to map directly to GoatTracker's internal memory structures, containing the following primary components:

* '''Header and Metadata:''' Includes a file signature, format version number, and song title.
* '''Global Parameters:''' Stores the song's initial tempo, timing mode (e.g., CIA or VBI), and the number of sub-songs contained within the file.
* '''Instrument Data:''' GoatTracker instruments are defined by hardware register manipulation. The file stores tables for ADSR (Attack, Decay, Sustain, Release) envelopes, waveform shapes (triangle, sawtooth, pulse, noise), pulse-width modulation tables, and filter cutoff/resonance settings.
* '''Order List:''' A sequential array dictating the playback order of the song's patterns.
* '''Pattern Data:''' A matrix of note values, instrument triggers, and effect commands (such as portamento, vibrato, and arpeggios) mapped across the SID chip's voices.

=== Version Differences ===
There are notable differences between <code>.sng</code> files saved by GoatTracker 1.x and GoatTracker 2.x:
* GoatTracker 2 introduced a 4th "track" dedicated solely to hardware filter manipulation, allowing complex filter sweeps independent of the 3 primary SID voices. Files utilizing this feature will not import correctly into GoatTracker 1.
* GoatTracker 2 expanded the maximum number of patterns, instruments, and order list steps, altering the binary layout of the file.

== Identification ==
<code>.sng</code> files can be identified by reading the file's magic bytes at the beginning of the file. The header typically begins with the ASCII string <code>GTS</code> followed by a version number byte (for example, <code>GTS5</code>, <code>GTS6</code>, or <code>GTS7</code>).

== Specifications ==
GoatTracker is open-source software written in C and C++. Because the <code>.sng</code> format lacks formal, external documentation, the definitive specification for the file structure is the source code itself, specifically the file saving and loading routines (typically found in <code>sndfile.cpp</code> or similar files within the source tree).

'''GaS''' is a file compression utility for DOS, developed by iNFiNiTY Software Productions (contact: Ricky Bhatti).

The compressor is GAS-UP.EXE, and the decompressor is GAS-DOWN.EXE.

== Discussion ==
The documentation says that GaS only supports text files, but in fact no such limitation seems to exist.

The decompression utility decompresses the file in-place, overwriting the compressed .GAS file. It then asks for a target filename, but has been seen to crash before it can rename the file.

'''Rainbow Chek''' (RBOWCHEK) by Dennis S. Lewandowski is a type-in program checker for Tandy TRS-80 Color Computer (CoCo) by The Rainbow Magazine.

'''Rainbow Check Plus''' by H Allen Curtis is a significant upgrade that adds support for the MC-10 and 4K CoCos.

Jerry Stratton wrote RCHECK+ in Perl and rcheck+ for macOS so that programs could be entered on modern computers.

The first version only supported the 16K and 32K variants and simply counted up the number of (crunched) bytes in the program, presenting the total in hex.

These totals were only provided after a group of lines, so they didn't specify which exact line had the problem.

Rainbow Check Plus has a running total of the value of all characters up to 255 (decimal) before rolling over. It catches far more errors than the original Rainbow Chek but still misses transposition errors.

'''DEFLATE 1-2-3''' is a possible name for a compressed file format used for installation by some Lotus software.

The decompression utility, INFLATE.EXE, calls itself "INFLATE, the 1-2-3 file decompression program".

== Format details ==
The compressed file has the same name as the original, except that the second character of the filename extension is replaced with "!".

The first byte of the compressed file is the filename character that was replaced. The compressed data immediately follows.

The compression scheme is a common form of [[LZW]], like [[Zoo]] or [[EA archive]], with a maximum code size of 12 bits.

== Identification ==
Realistically, good identification of the format requires that you either take the filename into account, or that you decompress at least part of the file to check for validity.

The first byte of the file is a character that can appear in the extension of a DOS filename, and it can't be "!" or a lowercase letter. That doesn't narrow it down much, though the official files might only use (uppercase) letters.

The first LZW code is a "clear" code (binary 100000000), encoded in 9 bits. This means the byte at offset 1 is 0x00, and the byte at offset 2 is an odd number.

The last LZW code is a "stop" code (binary 100000001), encoded in 9, 10, 11, or 12 bits. This works out to 11 possible bit patterns for the last 2-3 bytes of the file:

... 1xxxxxxx 10000000
... 01xxxxxx 01000000
... 001xxxxx 00100000
... 0001xxxx 00010000
... 00001xxx 00001000
... 000001xx 00000100
... 0000001x 00000010
... 00000001 00000001
... 1xxxxxxx 10000000 00000000
... 01xxxxxx 01000000 00000000
... 001xxxxx 00100000 00000000

'''Serious Engine texture file''' is a graphics format associated with ''Serious Engine'', a video game engine developed by Croteam for its ''Serious Sam'' series.

The format was also used by some third-party games that licensed the engine, such as:
* ''Alpha Black Zero: Intrepid Protocol'', by Khaeon
* ''Carnivores: Cityscape'', by Sunstorm Interactive
* ''Nitro Family'', by Delphieye Entertainment

A version of Serious Engine was released as open source in 2016.

== Identification ==
Files start with ASCII "{{magic|TVER}}". At offset 4 is a version number that's either bytes {{magic|03 00 00 00}}, or more commonly {{magic|04 00 00 00}}.

ASCII "{{magic|TDAT}}" usually appears at offset 8.

'''GPFax''' is fax software for Amiga, developed by GPSoftware.

One of its formats is a fax image format based on [[IFF]], with ''form type'' <code>FAX3</code>. It's not certain that this format is native to GPFax, but no other use has been found.

== Identification ==
Files start with ASCII "{{magic|FORM}}", have "{{magic|FAX3}}" at offset 8, and possibly always have "{{magic|FXHD}}" at offset 12
