I was already missing my old PSP (it got screwed when I attempted to install the TV Mod) after reading about flawless Neo-Geo and CPS1/2 support, but then the recent Playstation emulation stuff sent me over the edge. Managed to find a used system in great shape today at the first store I went to, and it only cost me 14,800 yen.
I haven't even gotten around to the PSX stuff yet, but just being able to play Capcom and SNK games so perfectly on a handheld...well...I'm crying tears of joy here.
EDIT: Garou MOTW, SSV Special, Sengoku 3, Marvel Vs. Capcom, Puzzle Fighter, D&D all on the go...*FAINTS*
