Ok, I now there is probably a forum somewhere with a walkthrough, FAQ, etc. But I have seriously must have tried every website and tutorial to get the cps2psp emulator and mame roms to work on my psp.
I followed the instructions on this website's own walkthrough, including downloading the latest cps2psp, making caches out of the roms, placing the roms in a separate file, everything.
I even downgraded my PSP to 1.50, and still nothing. I also reformatted my memory stick, as well as trying that psp brew application in hopes of making the PBP file work. Still, when I go to my game menu, the icon for the cps2psp shows up, but when I press 'X' to play a game, the error message shows up (80020001).
I have been trying to figure this out for the past 6 1/2 hours and I am at my wit's limit. What am I missing? Someone please help me before I lose my sanity.
p.s. You can also IM me or e-mail me. I'm desperate!!!
