This is the best emulator for me so far. It runs flawlessly. If it work for this, why doesn't it work for other emulators like MAME....i try it out and it doesn't run correctly. CPS2 works flawlessly. Street Fighter Alpha 3 is just like the arcade...and some of those side scroll shooter like 1944 is amazing. Now i want an emulator for MORTAL KOMBAT...enough of street fighter!! NEO GEO maybe ??? I dunno. I know you probably can play Metal Slug on Neo Geo. By the way, i am playing it with the PS3 controller and it's amazing.
