Once again I need to thank 1UP for his Dual Strike Hack. I created the same hack except I mapped additional buttons to run my 2 top fire joysticks. I mounted the main Dual Strike board to a small piece of Lexan and added a 12 terminal strip. The Dual Strike functions similarly to a keyboard matrix so it only takes 12 terminals to run my yoke and the 2 top fires. Connections 2,6,8,9,10 & 12 provide me with 12 buttons for the 2 top fires and the yoke triggers. The 5 remaining connections run the x & y axis of my yoke. The Atari yoke XY axis red wires are connected together because they are both grounds.


Here is a picture from 1UP's Site that I modified to show the additional button mapping. Connections 6,8,9 and 10 require a 1N4148 diode at each microswitch to prevent masking.


Here is a diagram of how the buttons map to the Dual Strike. I found these mapping through a web search, but unfortunately I lost the site and can't give the guy credit. In case anyone needs 2 more buttons the button marked X is mapped to 6 & 7 and the button marked Y is mapped to 6 & 12. I never figured out the combo for the button with the up arrow. If I ever replace my yoke grips with the thumb switch version I will probably use these 2 extra buttons. Currently, the yoke triggers and top fire buttons share the same connections because they are on different sides of my tri-panel and never would be used at the same time. The Dual Strike software is excellent. Once I changed the mode from FX to joystick and made a slight adjustment to the y-axis dead zone, everything worked like a charm.

People have pointed out that my mapping combinations are different from the ones on 1UP's site. This is true, but they still work very well.
