are there are any tools to extract this archive? It has 3d models, and textures in them as far as i know.

There is something missing.
It's a sequence of chunks containing a dynamic list (you don't know how many elements) of NAME/OFFSET.
The problem is finding the size of the last file of the chunk and so finding the next chunk.
I think there is an index file.

I think I'll have a better dump by tonight.

EDIT: Here it is

Same.

Idk if this will help, but below is the decrypted ARIKA.DAT:
http://www.mediafire.com/file/1m4ghyxay ... A.DAT/file

Offset 0x1C represents file length. Can't really interpret 0x00 and onward for file name listings with VFS extraction of VGMToolbox. Not sure what 0x14~0x1C represent, likely file offsets but can't make a connection with it based on their size 0x04 Little Endian values.

The first 4 megabytes of PS2.dat and its total size in bytes would be helpful

[aluigi]

The first 10 megabytes are better

PS2.DAT (10MB trim): https://mega.nz/#!nHxByAhL!PBsgdOO1L1CC ... svXywfvIEw
Total size: 604,702,720 bytes (0x240B0800 bytes)

The script works with both PS2.DAT (or arika.dat, it's the same) and the extracted pac and mdt archives.

[AceK]

Thank you a ton! Works like a charm!

Sorry to bump this, but I'm having trouble getting this script to work. I've tried this with a couple different versions of the game, but it never seems to work. I used this like any other script, but when I select either Arika.DAT or PS2.DAT nothing seems to happen. I've attached an image that shows what's happened every time.

[aluigi]

The only way is uploading the 2 files so I can take a look at them.

Since they are big it's probably better to use the filecutter script and uploading the 2 files generated from each one of them:

Alright, here's the files from PS2.dat. It said that Arika.dat (40kb) was too small for the script, so I just included it in here too.

[aluigi]

That ARIKA.DAT is obfuscated.

[BloodRaynare]

Just found this thread and yes I've been looking to extract the files of this one too

FYI, based what I'm looking looks like the ARIKA.DAT header files is encrypted with XOR
The problem is it seems that something is missing

Code: Select all

EB DA 6B 4B EB ?? CA 9B AB 7A CC ED ED ED ED ED

As you can see, it's missing one of the keys that needed to decrypt the files correctly. And how the thread starter decrypt the files?

[aluigi]

What a mess, yeah still something missing.
