[PSP] Metal Gear Ac!d 2 (_ZAR) File

[E3245]

Hi, I'm trying to extract files off this archive from Metal Gear Ac!d 2. I uncompressed it using offzip to a *.dat file, but now I can't find a way to open the *.dat. Konami DAT Unpacker doesn't recognize it. If there is a way to open this file, I would be appreciated.

The _ZAR file has no extension. This is from the init folder, most likely the main file for models, textures, etc.

It's a file compressed with zlib, you can unpack it with offzip.

The resulted file is a sort of archive with a not so simple format.
I suggest to use offzip -a on it.
