Thanks to whoever dumped the DLL, it helped me to figure out the xor keys. I made a small converter in Python.
Edit: apparently it doesn't work with the latest client, I need a new dump of the DLL...

After a weekend spent unpacking the latest DLL (Themida is a bitch), I finally succeeded in finding the new table and xor algo. Here's an updated script which should support both versions I had access to. It checks that the data unpacks cleanly and CRC matches to detect the AION version.
pak2zip_02.zip
Supported CrySystem.dll versions:
1.1.7.1221 (2285568 bytes)
1.8.1027.415 (2666496 bytes)
If you have a different version which is not handled, please post the DLL.

rokfan, does this mean it creates a "zip" file that you can extract? But i guess the models are still some weird format that needs to be converted to?

oh :) i hope someone can take a look at textures, I have ripped models with a 3d ripper but it doesnt take normal maps and specular maps. If we can't figure out models maybe textures?

Hi,

I am searching info on the xml files that can be found inside some pak files. Everything else unpack with success but the xml files seem to be crypted. Do you have information on this ?

Hi

The python script fails for Sounds_music.pak. Could you check why?

Thanks for your script :)
I'm new to all of this so I've got one question, how do I run this script?

When I try to run it, I get this error =o

Code: Select all

Traceback (most recent call last):
  File "D:\pak2zip.py", line 57, in <module>
    "\x2f\x5d\x51\xf7\x01\xe9\xb4\x93\x4e\x51\x81\x3e\xaf\x3f\xdf\x99"
