Since the OP apparently no longer cares about this, I leave a link to a resource and a keyword for the search engines:
https://github.com/alin1337/DNSkyProject (DNPakCrypto/DNPakCrypto/Main.cpp)
Ralukat Labs Packing System 1.1

Basically it's just a set of different XOR obfuscations based on the section of the archive to decrypt, I mean like:

Code:

buffer[i] ^= buffer[i - 1] ^ cheimagice[i % 512];
buffer[i] ^= rlkt[i%(sizeof(rlkt)-1)];
buffer[i] ^= cheimagice[(j 0x69) % 512];
buffer[i] ^= buffer[i - 1] ^ cheimagice[j % 512];
