I recently opened my MAS stick to see what joystick was in there since it was build in the 90’s. Its a Happ Ultimate so I wanted to see about putting a Sanwa in there along with Sanwa buttons. Currently it has Happ buttons in there.
How hard would it be to swap them out? I understand what is involved with wiring wise but I really mean hardware wise. Would the sanwa stick and buttons fit the Happ openings?
