[PS2] Detective Evangelion - .DAT

Post by akderebur »

An archive from a ps2 game developed by Broccoli. I am hoping someone can identify the compression used.

I am uploading a small dat file and the elf file : https://www.mediafire.com/file/idy8k66o ... T.zip/file

Thanks.

That dat is all obfuscated, it may be a known obfuscation seen in other games but it's difficult to say.

Thanks for taking a look. I guess it will be hard to figure this out then.

I have found some segments related to the ".dat" files in IDA Pro. I am not familiar with MIPS opcodes, or with assembly in general. So I couldn't understand much looking at it. Maybe it might mean something to you.

This an old unpopular game, so probably not very interesting :D Still I appreciate the help.
