Oh thanks didnt realise it wasnt as i saw it on the mame list. So whats best to stick with mame or put zinc on and my mate was also mentioning that capcom vs snk is also emulated but its not on mame either would that be zinc again for this game?
Get a mate that knows what he is talking about is your first step.

Capcom vs Snk ins't emulated because it's a naomi game. The closest you can get is to run it on chankast (a dreamcast emu). Zinc only emulates games based on psx arcade hardware, which are generally 3d, and generally capcom or namco titles. (Think SF Ex and tekken).
