MAME is only an arcade emulator (Multiple Arcade Machine Emulator). NRX, Kawaks, Nebula, FBA are MVS and AES emulators. SSV:Special isn't new news, infact it's old. It was supposed to have those characters and "fatality" moves. And can't you play as Ga-Oh, Yumeji, and Sankuro if you mess with dip-switches?
