There's a lot of good 2d fighters on Mame, such as King Of Fighters, Street Fighter, Samurai Shodown etc. (But unfortunately I can't download them as I don't own the original arcade versions
)
However I've heard that although they run fine with a 100% frame rate, the shadows beneath the characters tend to flicker a lot and can be quite annoying. So if anyone knows how to stop this from happening please let us know. (just curious like)
