OBD talk:File types

Below is an overview of individual template checksums, extracted from the three engine types (Windows retail, Windows demo or Mac, and PS2). For conciseness, we may refer to the three iterations "Win", "Mac" and "PS2" (Windows demo and Mac differ only in the ADPCM algorithm used for the waveforms stored in a SNDD's .raw part, which does not affect the template structure or checksum, and is outside the scope of this analysis).

Our knowledge-so-far suggests that Windows retail was the first iteration, followed by the concommittent development of Windows demo and Mac versions. The PS2 iteration apparently came last, being closer to the "Mac" iteration but also having many novel features (color palettes, text system, but also AGQG, M3GM and TRAM). At the time of writing, we have yet to document the PS2 "novelties" and determine whether or not they constitute an improvement.

The instance files are labeled as VR31 for all three iterations of the template system, even though Windows retail doesn't use .sep files, and PS2 seems to be using additional .pal files (palettes of all the texel colors occurring in a level; not yet documented).

It must be noted that the PS2 build includes an auxiliary set of sound files, grouped by level into .dat/.raw/.sep file triplets (i.e., 15 such triplets in total). However, these auxiliary .dat/.raw/.sep files are nothing like VR31 instance files, and seem to be using a much simpler lookup system (undocumented as of now).

For most templates the checksums are identical, as well as the data itself. One template, TREX (Totoro Animation Extra) is unique to PS2 (apparently some of the TRAM data was split off to a separate, unnamed file; possibly new TRAM features were implemented in the process as well). Another template, AGQM (Gunk Quad Material) is missing from the PS2 engine, so that each engine lists exactly 114 individual template checksums, plus the global checksum. The global checksums aggregated from these 114 templates are as follows:

"Win" checksum (Windows retail)

0x0003BCDF33DC271F (doesn't include TREX template)

"Mac" checksum (also Windows demo)

0x0003BCDF23C13061 (doesn't include TREX template)

PS2 checksum

0x0003BA70A8DBAE11 (doesn't include AGQM template)

Below are all 115 known templates in alphabetic order, with their checksums and data sizes.

• A black background indicates those instance types that do not occur in Vanilla .dat files.
• A grey background indicates those that are present but are not used (by Win/Mac engines).
• A green checksum background indicates files that have a different checksum in the Win iteration.
• A yellow checksum background indicates files that have a different checksum in the PS2 iteration.
• A red checksum background indicates files that have a different checksum in all three iterations.

The data sizes in the below table are extracted from the respective engine executables (along with the checksums) and include the 8 leading bytes (instance ID and level ID). The number in square brackets is the size of the variable array element where applicable. Note the difference with the padded size featured in an instance descriptor (which includes the actual array elements, if any, and the 32-byte padding).

Note that some obsolete instances, such as OBLS, are worthy of interest, have been documented and may be revived.
