PS2 - TEKKEN 5 *.bin files (looking for file tables)

[r88]

Hi, I wanted today to extract tekken 5 resources, so they are obfuscated and compressed but that is not the main thing now.

I've stuck on finding file table, it seems hidden somewhere else in executable, so I'll attach part of the archive (they are big) and executable.

So, my researches are: The obfuscation are require a file id, that I think must be in file table also with the flags (obfuscated, compressed, as is), next it doing some math with this value and xor the 0x800 bytes of it on the value. So each file have unique xor key. Compression seems to be LZSS or similar.

I think each file in archive starts with

01 00 00 00 08 00 00 00 2B 44 00 00 DA 00 00 00

or it's meant for something different.

tk5data0.bin.rar

SCES_532.rar

Seems like a classic PS2 bigfile, basically what you have to look for is the offsets of what you think are files divided by 0x800, it might also only store the sizes/0x800 of each section but I'd definitely try dividing stuff by 0x800
