Used in the following games:

  • Parasite Eve 2 (PSX)

Parasite Eve 2 data archive format. PlayStation games are tricky to reverse since the game may not use the file's positions to access data but rather the physical disks sectors. Which means the original disk image would be needed to extract data properly. :T


Notes:

Comparing all STAGE*.CDF files...

Location: 8224

Disk 1 (SLUS-01042)
LBA Name Description
0000023 SYSTEM.CNF
0000024 PE_DISK.01 Unknown if used. Size of sector?
0000025 SLUS_010.42 Program
0000204 INIT.BS "Published by..." image.
0000210 STAGE0.HED Header? Possibly some LBA locations
0000214 STAGE0.CDF Data archive?
0030255 STAGE1.CDF Data archive. Has soundless STR
0075564 STAGE2.CDF Data archive Has soundless STR
0100127 STAGE3.CDF Data archive
0117576 INTER0.STR All FMV with sound.
0225526 DUMMY.DMY Dummy file that is actually a video not related to the game.

Note on INTER0.STR Due to the file size, I suspect that this may contain all the FMV data on the disc. However, it was very common for PSX games to access the disc directly rather than access the files via the file system. This makes extracting data more complicated, at least for FMV/STR/Videos. Other files may be the same as well since due to the tech limits of the hardware, developers had to be creative with their engines.

Due to the way the game works, it may not make sense to have a page just for one format but rather the whole game. PSX games are a pain to deal with since the formats are, at times, tied to sectors.
