Alright. So I have devhook installed. DevHook 0.51 fw 3.0x . And I was deleting an ISO game, to make room for another one. Accidently, I deleted a file called ! XMB BOOT (DO NOT DELETE) !.cso And now my games won't start. I can't restore the deleted file. And I've searched google for an hour now and I cannot find it. Any help?
