I noticed that on unreal engine games when the dlc is deleted the inventory items are not deleted. They only disappear when the system cache is deleted. The dlc files are copied into the cache folder. These cache files are readable with a program called x360tool1.3 . On my xbox the cache files are unreadable for what ever reason. I need one that i can readable and editable to some degree. The game in question is Transformers FOC for xbox 360. If you have the game it would be as easy as you playing the game once in multiplayer. Restart your xbox and get the files from xbox neighborhood. Im willing to drop $5-10 on this.
