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

[L33THAK0R]

Hi all,

Been looking into Sleeping Dogs, and after a bit of discussion with some more experienced/technical tool engineers, I've got to say I'm quite intrigued. It uses a very aggressive "LZ" algorithm, with a given ".BIG" (archive format for the title in question) decompressing to over twice its original size! It also seems the WWise ".pck" files used for audio within the title have the potential for additional gains using "OGGRE"/"MSC". Unfortunately for the former I don't possess the skill-set (yet) to adapt the provided compression/decompression algorithm to be able to parse inputs for use with a chain of compressors, but none the less I think its still interesting enough for others to see.

Attached is a tool suite for processing the aforementioned ".BIG" archives, as well as a sample archive.
