This python script extract the .PAK file find in the steam version of Kao The Kangaroo 2.
Tested on Python 3.7 on Windows 10, should work on other system as well.
Usage:
python unpack.py {file path}
The rough structure of pak file is in Pak_Structure.txt, I figure it out myslef because I have nothing else to do.
I might write another script to repack the file in the future.
Any feedback is appreciated.
