ok, i have backed up my games (gran turismo, and my buddy helped me out with marvel ultimate alliance 2) ok, dont ask me how he got alliance 2 for psp, but he got it. alliance 2 acts the same as my gran turismo. also as a side not i have now removed my umd for speaker mod i have been wondering about. i use his psp to dump my umd's. anyways, when i try to run my gran turismo and alliance 2 i go to a black screen and nothing happens. all my other dumps work. when i goto alliance and GT in the game menu i get the demo screen like any other dump but like i said i get black screen, and nothing. any suggestions? oh yeah, i am also running 500 m336. since these are newer games, do i need a newer cfw?
another edit, lol. i just read that if i want to play gt and so i need 600 and if i need that i should goto timemachine. man back to timemachine? will this work? how should i go about installing timemachine and play new 600 ofw? i read if i do use time machine and and upgrade to ofw i can just press L at start and goto test 500m336 and be fine. is this right or am i wasting my time?
