Save file data at the start end the table at the end. Then maybe put CRC32 or some other hash values in the table and sort it by them. Then to locate a file, you hash the passed filename and do a binary search for it. Also need to normalize the path before hashing, so you get the correct hash.

The game is written in some .NET language. Use .NET reflector on it and you will find the complete spec for the model format.

Trillix works well.

It's actually .loc files, they appear as .bod because of the way offzip extracts things and the way the data is stored in the .upak files.

Does this game also have CAS/CAT files like BF3 does or only the .toc and .sb files? I made a tool a while ago that can extract certain files from BF3 (textures and the UI stuff) and it might work with this.

Found most of the info including the hash stuff, which appears to be CRC64, by reverse engineering/debugging the game.

I think there are too many unknowns for that right now, especially the hashes in the OBPK data.

Posted my extractor for DS2 there: viewtopic.php?f=10&t=9475&p=77690#p77690

Finished my extractor for this. It doesn't do a lot of validation so it might crash if a file is corrupted or something.

The download comes with its source.

The pc.mnfst and .upak files contain OBPK archives which in turn contain the files (uncompressed filetable + deflate compressed file data).
