Don Bradman Cricket 17 Mob! files

Post by Wouldubeinta »

Hi, I was wondering if someone can take a look at this file and tell what encryption this file is using. I believe it might be 128bit AES, not to sure, it looks like it's got some sort of table before the encryption.

EXE Log from Luigi's Signsrch:
