wait a min, what about installing it so u can launch bo2 from the xmb without manager (i dont remember how though) that way u can switch to usb mode and launch it as if it would be a psn game.
ps: your ideas dont work cause when u switch to usb, the game disc gets loaded again, even in apphome.
But my idea is to use it with the xmb launching/psn game style (haha) method. Get me?
EDIT: I've found this but its only for 3.55 http://gbatemp.net/threads/guide-to-...on-xmb.290011/
EDIT2: I'm not sure if im allowed to post links, if not sorry
