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

[L33THAK0R]

Hi all,

Has anyone given "Call of Duty: Black Ops III (3)" a shot? It piqued my interest when I saw the QuickBMS script for "xpack" archives[1] mentioned that the "LZO", "LZ4" & "Oodle" compression algorithms were used within these archives. I'm sure testing which libraries for "LZ4" give the best output won't be too tricky, but in regards to the "Oodle" codec(s) used, I'm a bit stumped. As far as I know a "oo2core_#_win64.dll" is required, with either "xtool" or "Oo2Rec#", to pre-compress a given file, however such a file isn't present within the root and sub-directories of the title in question. Does anyone have any idea how to go about pre-compressing the "Oodle" streams for this title? Apologies if I buggered the terminology.
