I convinced my friend to get custom Firmware installed on his PSP. After not wanting to do it, afraid of bricking it and all, he finally did! HOWEVER, he can't seem to get it to run any ISO's. All his ISO's bring him to a black screen, but the PSP is still on. However; He can't turn it off. He discovered that by ejecting the disc, it brings him back to the menu. (The disc he was using was Tales of Eternia.) But, when he tries it with GTA: Liberty City Stories inside the UMD Bay, he gets the same problem; Only when he ejects the disc, it says the game could not start. The main issue is: How can we get it to run PSP ISO's?
