I recently burned a copy of COD Black Ops but when I play it on my 360 slim a black screen appears and nothing else happens. I first patched it with ppfomatic and then ran it through abgx twice and even burned it using imgburn at 2.4x, I don't understand why isn't it working. Other backups are working fine e.g. NFS Shift 2 and lego Starwasrs 3! I got my slim modded(was lucky enough to have a 9504 drive) a few days from a local shop and i'm pretty sure the guy used the latest LT+ FW! I hope you guys can help me out here! Thanks in advance!
