Hello, I've been looking at these files from WWE 2K16:

https://mega.nz/#!U95TwDJa!xXdR0iMsbD5N ... Cs1KC59CxQ

What's there is a regular pac file and then its a zlib compressed PACH but it doesn't seem like regular zlib. I was wondering if anyone had any clue as to how begin writing a script for this and if its even possible?

The data that I do know:

- Headers of the .pac files are always either "EPK8" or "EPAC".
- Next value long is always null
- Then another long value which seems to be the size of the archive (or possibly offset?)
- The names of the archvies always start at offset x00000800 and the data itself always starts at offset x00004000.

Apart from that, I have no idea how to begin opening the zlib compressed ones. Any help is appreciated

yuke.bms extracts everything perfectly and the results of both the files are identical, so what's the problem?

Problem is I'm an idiot :p

Thank you for replying. I did try to unpack the zlib files with Yuke but some don't work. So if anyone encounters this use off zip to unpack those.
