It exists since ages, it is a VMM. Performances will highly depend on the emulated system himself. Despite Neogeo sprites roms are really big (64 MB for the biggest games, and more for the PCB revision of KOF2003), it is fast enough for all games ---> 60FPS. Just have a try with the smallest PGM games (games who don't need a VMM as you have enough memory), like Photo Y2K. It is already slow as fuck on my Xbox, the CPU is crying A "solution" would probably to use oldest PGM drivers (the Oopsware one, before iq_132 rewrote the code ), they have a decent speed and iq wrote kind of very nice VMM for it, at least 2 years ago. The latest iq_132 PGM drivers will definitly not run at a decent speed. Mooooo. PS: Dave the whore, how it's going?
