Mame-X, is there a way to play 13+meg games??

[infidelity]

Well, I guess I can't add more ram if I won't be able to play xbox games. It's just pissing me off, cause fbax plays only capcom games, and those games are 19-20 megs, and play sound flawlessly!!! Now, why isn't there an emu that can do that for all roms??? I hop they come out with an update really soon. And the neogeo section of the mame-x b6 emu, certain game will only appear in the neogeo section (aka, the blue screen) is there anyway to make my mortal kombats appear in that neogeo screen??
