ok i ripped it using origional disc using sh-d162c flashed with kreon. xbox backup creator 2.7 like i do normallyl with all my games that work. Did complete backup and burnt at 2.4x then 8x the other time. heres the thing the game works fine up intil level 4... when i go to leave the level it just goes black and locks the whole xbox up. I reburned it same thing. I burnt it for a friend, his works up until level 7 then does the same thing. Another friends only loads the menu and locks up. Is there something im doing wrong? any help would be appreciated.
