Yeah, strictly MAME/Emulator. Dont think I will aim much higher than supermodel games. Does this mean the standard ffb/wheel set up should work well enough?
Not sure what you mean by "the standard ffb/wheel setup".
If you mean the one in the virtua racing cab, then it depends on how you intend to interface it with the pc and whether you expect the ffb to still work. It's a lot easier to interface if you're not worried about the ffb. If you are, see my earlier comment. There are no other options. If you're not worried about ffb working, a U-HID or A-PAC from ultimarc is all you need.
If you mean a standard ffb PC wheel and pedals added to the cab (getting rid of the original arcade stuff), then yes it will work well enough.
I prefer Logitech wheels because the profiler software allows you to configure the wheel differently for different emulators if need be.
