Our friend Nexis2600 or his other nick PSMonkey as he also calls himself who for those that dont know is the coder who released the only NeoGeo Pocket Emulator for the PSP which is NGPSP and was exclusively released here on the DCEmu Homebrew Network forums --> http://www.dcemu.co.uk/vbulletin/showthread.php?t=6077
Now to get on with the topic i have had the chance to play the unreleased version that he has been posting around on his forums and other sites and my conclusions are that it is simply stunning, i do know that PSMonkey is planning to release a game using this engine and you will be impressed like i was and without a shadow of a doubt it will be the best looking homebrew game on the PSP, wanna see screenshots, well check out this topic --> http://www.dcemu.co.uk/vbulletin/showthread.php?t=15168
