Since I'm replacing the joysticks and buttons with better quieter microswitches, I'm just going to wired them how I like it. So I could give up 4, of the six buttons, to add a joystick.
Still, I'm trying to avoid having to re-do the cabinet. I would be really happy if I could just replace the original joystick with a switchable 4-8 way from Ultimarc or similar. Has anybody here done that?
