Hello, everybody. I have a small problem, I cannot load any ISO from my memory stick. My PSP used to be a TA-082 motherboard with firmware 2.60, but I downgraded it to 1.50 and then upgraded it to 3.30 OE-A'. Everything works perfectly... except ISOs. I have skimmed through this forum and did the following things suggested by other users: In Recovery mode: -disabled no-umd. -disabled the three options in the advanced configuration. -turned CPU speed for UMD/ISO to something else than 333mhz. The two ISOs I've tested are "Tales of World Radiant Mythology (J)" and "Puzzle Quest". They are both in an ISO folder located at the root of my memory stick. They are both detected by the PSP in the game section. I even have a Lumines UMD inserted in the PSP at all times. Yet, when I load one of those two ISOs, the PSP logo appears, then the screen turns black and nothing else happens. Can anyone help me?
