This emu has got to be the best emu to run on the PSP so far imo. Its called Neocdpsp 0.5.. Neocdpsp It has a few glitches but the games look nice and full speed. Heres a screen shot from Kof99 from my psp. Im very impressed. If anyone with a 1.0-1.5 psp wants to try this emu ill help ya get it running. Recently version 1.5 us version of the PSP has been hacked with a program called KXploit. It lets you run code on a 1.5 PSP. PSP Versions 1.51 and 1.52 wont work.
