I have a FAT PSP and I've downgraded to firmware 3.71 M33-2 using Pandora's battery. When I go to system setting, it says 3.71 M33-2 but when I put Iso games inside the Iso folder, the Iso loads but I get another message says this game can't be played !!!
Am I missing something, do I still need a UMD disc inside the PSP to load the games from the memory stick !!
