I finally downgraded my psp, then installed a custom firmware 3.40oe. I'm making my ISO's, I'm getting a 50% working ratio. I've been reading that some games need these loaders to help them start. I don't know to much about all these different loaders. Is there a list I can find, to figure out what games need which loaders? Maybe then I could start figuring out the loaders. So far, I have tried the latest UMDEmulator, which someone was telling me about. All I ended up with is a corrupted file located on my memory stick. Which doesn't work. Could I get some assistance?
