The original PlayStation engine loads 512 bytes of data (GAMEWAD_HEADER_MAX_LENGTH) into the gamewad buffer. Level file entries contain 3 other files prior to the level file itself.
- 262144 bytes of data is a 16bpp 512×256 BGR loading screen image.
- 8192 bytes of data is a 16bpp 64×64 BGR spinning CD image.
- 42012 is “SETUP.MOD” an external module similar to a DLL file (for the final NTSC version of Tomb Raider Chronicles) the size may vary depending on the version.
UNKNOWN_41 and UNKNOWN_46 are identical. UNKNOWN_44 and UNKNOWN_45 are too. Same for UNKNOWN_43 and UNKNOWN_47. And UNKNOWN_44 and UNKNOWN_48.
For the file to be loadable by the PSX engine, all the file offsets must aligned to 2048 (
0x800). i.e. they must be aligned to the next multiple of 2048 which is the size of a single CD sector.
