CDF

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

LBA	Name	Description
0000023	SYSTEM.CNF
0000024	PE_DISK.01	Unknown if used. Size of sector?
0000025	SLUS_010.42	Program

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.
