Played my NeoGeo on this quite a bit, but no longer need it do to having a cabinet 
It outputs composite (Red, White, Yellow) and Svideo I believe.
It also has a kick harness that Ive never used, not positive what system its for though :P
You can see it there, hooked up to my Naomi
215 shipped for the Supernova/Gun
Also seen in that picture is my NeoGeo 4 button Mas joystick, which has the awesome perfect 360 joystick. No longer need this as well
