I might be getting an HGA soon I was wondering though, is there anyway to use official NeoGeo Joysticks with it? Also, If I got a MVS board that had built in joystick ports, would I be able to just use those instead?
What's a HGA? Anyway it should be very easy to build an adaptor for any supergun to accept Neo controllers, that by the way work straight away in a MVS board with built-in ports (not all MVS boards have them though), as fami said.
