My PSP 3000 is on 5.03 M33-6 with the ChickHEN mod. I managed to pick up a copy of Little Big Planet today that was miss priced at $10 planning to turn around and sell it again, but this is a game I've been meaning to play eventually. I'm reading all sorts of weird things about it working and not working on M33. Long question short, is there any advantage to having the real copy of this game over the ISO? I know the usual case is no, but does the disc have any features that the ISO doesn't have? And can I even run the game from the disc without it having to update my PSP to something I shouldn't update to?
