Will there ever be a 32X emulator for OS X?

I hope so, but it seems unlikely. There isn't even a decent Mega Drive/Genesis emulator for the Mac (well, not one that plays all the popular games).

I'm not sure if there ever will be one for OS X, maybe in the future Fusion will be ported over to it. When it comes to Windows though you have a choice between Gens and Fusion, Fusion being the most accurate.
