Ok, i followed the instructions and successfully downgraded my psp from 2.0 to 1.5 and got all the very cool emulators to work. Problem is, when i go to start a umd, it tells me i need to upgrade back to 2.0 to play them????? Any way around this? After all the effort of downgrading and getting the emulators, i don't wanna lose them. Can anyone help?
