Best Compression Methods for 'Specific' Games. Q&A

[KaktoR]

I would try to compress the files with zip with same zip settings and password, then make diff patch to patch files back to original. Not sure if this will work, could be difficult because of the password protection.

yes it's more or less what I tried

In fact this file, basis.pak was uses as a mounted drive/partition
There is a structure like if they done an usb/harddrive image.

I'm starting a test, maybe the game do not check the crc of this file.
in this case probably I may unpack/repack without problem

I'll give an update this evening

Game runs with unpacked data.
