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
0075564 STAGE2.CDF Data archive
0100127 STAGE3.CDF Data archive
0117576 INTER0.STR FMV related*
0225526 DUMMY.DMY Dummy data?

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.
