2K WWE .CAK files

Post by eri619 »

Since Yukes stopped developing WWE games this year, 2k has encrypted the game files in a new format called. cak file. Could someone help me extract the contents of this file? The file size is a bit big, but its the smallest one I could find

Here's two small .cak files from WWE 2K20. http://www.mediafire.com/folder/gzwcte87oa66j/cak.

As to what these files are, they appear to be encrypted directories and within these directories are Oodle Kraken compressed assets.

It seems some early research had been done prior and someone was able to program something to work on .cak files like "140.cak" in the folder and patch 1.01 "bakedfile"s (https://github.com/pozzum/WrestleMINUS), however some header flags are different on the second CAK in the folder causing the program to crash. The program creator has abandoned work on CAK files since then so not much has been done past the patch 1.01 cak files.

The "FDIR" at the beginning is the only thing with a sense.
Everything else is probably obfuscated.
