Does anyone know if game updates are console specific? I'm asking about CoD: world at war in specific. If you have the 1.07 update installed (by running the game from disk in non-jb mode) then it will work with backup manager. Otherwise it will just black screen.
Could I copy the game data folder to another console and have it work on that one without the original disk? I don't know anyone else with a jb-ps3 to try it out.
