I set it up with my 4-way Stick.
Up = UP not Left not Right
Down= Down not Left not Right
Right = Right not Up not Down
Left= Left not Up not Down
Sinec my 4-way is a true 4-way (Diamond shape joystick), feels/looks like its working except for the feel of course that I can't go diagonal. But all in all, Q-bert is working great. Now I have to try Congo Bongo. As far the Zaxxon, I might set that one up with the 8-way stick.
