I would doubt not many. Those machines are too darn huge to have inside a person's home arcade. I still love that game and had an upright, but no way would I even think of getting a cockpit. For all the room it uses, I have more important use for the room.
i've worked on both models. fun game.
you know, if you ace all five races you turn
into the afterburner jet or the super hangon bike
for a special sixth race. i love extra things like that!
