Sadly this emulator is extremely buggy with ATI video cards, and some games are just unplayable with them (for me, at least).
I'm really looking forward to the rewriting of the PCSP (PSPE now), and the Sowiz's PSP Emulator. Looks very promising.
I actually have a PSP, but play some gems like Monster Hunter 3rd and Phantasy Star Portable on my LED screen at 720p/1080p would be priceless, lol.
JPCSP runs some games pretty well, but it's a pain in the ass to set up options properly, since i have an ATI.

JPCSP has a software rendering option now that might work better with ATI cards though it might be slow depending on the game.
Maybe one day ATI will get their act together and fix the buggy OpenGL implementation. :\
JPCSP works well with 2D games. The sound support is actually the flakiest part of emulator, because external programs are required to decode some audio formats.
W00t Sindel is using my kung fu style, cool!
