I have been checking out a couple emulators to see if they work. First up was MVSPSP 2.3.2 even after finding the Neo Geo emulator I had issues like how to install, and why were there 3 Eboot files. But even after I had that figured out, it didn't work. The same with MAME4ALL calling itself a MAME emulator for the PSP preloaded with 82 games. I will keep on trying and let you know the results.
