Re: Ace Attorney Pachislot Extract .OBB extension but .CPK?

Post by YDGeon »

I managed to extract the .obb files (they are actually .cpk files obviously) using VGMToolBox and got some .png files.
But there are some files that I cannot find the formats of because the signatures are not there when I checked with a hex editor.

I think they are encrypted or something, is there a way to find the decryption key?

Samples (they are .bin): https://mega.nz/folder/STIzXArK#kBCFrIJyeqD4Oz7DQKU-HQ

I got this far as well with VGMToolBox. I have also tried using quickbms and got a bunch of Null files. Hoping someone has an answer to a way to decrypt these if possible.
