Stuff like AvP is better handled by a more specialized emulator than MAME. Something like Kawaks or Final Burn.
Anyway, the GPX2 came out this week and they already got the thing playing NeoGeo, Gameboy, SNES, Commodore 64, Quake, Hexen, and Quake 2, and playing DivX movies nicely without resizing. Even has built in TV output, which I didn't realize. Seems to be delivering on its promise of being a homebrew dream.

Alot of the stuff is slow or incomplete, but considering they're the result of less than 3 days work, I can forgive them. Most of them aren't taking advantage of both CPUs yet nor any ASM optimization and estimates are that they should get 4-8x faster as they develop.
