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.

  1. 262144 bytes of data is a 16bpp 512×256 BGR loading screen image.
  2. 8192 bytes of data is a 16bpp 64×64 BGR spinning CD image.
  3. 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.

UKPIK_START and USAPIK_START are identical. ITALYPIK_START and SPAINPIK_START are too. Same for GERMANPIK_START and JAPPIK_START. And ITALYPIK_START and DUTCHPIK_START.

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.
