I also attached script + file with filenames since filenames are hashed.

Thank you as always! And happy new year!

The problem is the COMPTYPE field which is not handled.
All the files before the error are COMPTYPE 0 while the one with the crash if COMPTYPE 1.
I'm not sure what algorithm it should be.

[h3x3r]

That's strange because some of files which are compressed with oodle are decompressed properly but some of them can't be decompressed and throw error.
Files which starts with 8C 06 are decompressed but files starts with 8C 0A and CC 0A are not.

[aluigi]

Since the failing decompressions are those related to COMPTYPE 1, I guess that field means that some oodle option is used, for example a dictionary.
I don't know what's the version of oodle used in the game.
quickbms uses version 2.6.3, the 2.7.x branch doesn't seem to have new algorithm or new versions of the existent ones (in decompression), but still that different field means something not related to the library.

[h3x3r]

There is file called oo2core_7_win64.dll Do you know a way how to bind it to the script? Thanks!
If you will need a game i can grant you access to my account with game.
BTW it's not important "since there is already unpacker" but i would like to see how that code looks in BMS. For future games like RAGE 2 and all new APEX engine games.

[aluigi]

It can't be used in quickbms with the calldll command because OodleLZ_Decompress requires 14 arguments while calldll supports max 12.
Anyway I guess there is also some bug in comtype calldll since the function is not found.

Ah, you can't use 64bit dll with quickbms, luckily there is a 32bit version too.
