Right iam on 3.03 oe-c and iam having trouble running some ISOS. When i download them i generally use a distributor called ESPAL.PSP and they all work well, I downloaded and played MGS: PO and GTA VCS and they worked good. I downloaded Burnout Dominator and it wont run, i get a black screen after running it from the game menu. The psp is on and the memory stick icon is flashing but nothing displays on the screen unless i press home screen button. I have set no umd to disable and used a umd, and vice versa. Basically i have the same setup Ive always had but ratchet and clank, and now burnout dominator none are working despite numerous dwnlds of different ISOS.
