you need custom firmware or jailbreak on your ps3 1st of, and thres a sticky thread explaing how then

no you dont have to have to have cfw. there plenty of tutorials around though so have a look. i assume your talking about mw2? All you need is a patch blocker and the hack.

Link to patch blocker: You must login or register to view this content.

You will have to find the hack on your own (not hard to find)


Best of Luck
