Hey guys, I found out that it is 100% possible to modify Assassin's Creed 3's 555308AE.gpd File. In the GPD you are able to see your achievements which are unlocked and even the PREORDER UNLOCKABLES I just cant find them :P. So I'm trying to find them, and the best way IMO to narrow down the location of where the unlockables are in HEX has to be getting your GPD before redeeming a Pre-Order code, then after redeeming a code, get the GPD and find the changes. So if someone could help me out in figuring this out I would be glad. I found this GPD on 360Iso which has EVERY Pre-Order bonus, so it would be good to use it as reference to your own GPD!
