Grab your switch matrix chart. When you put the game into switch edge check manually trigger each switch and make sure that it registers on the DMD the switch that it actually should be registering. On my getaway I had a shorted right trough switch. It made the shifter read as ball lock one and the game continuously auto fired the ball. Manually check each switch and begin to isolate the area of a short. If you accidentally bent a diode and grounded it out the switches won't register correctly.

Lol. You beat me to it.

I used a rottendog board in my hs2. It worked well for me hopefully it will fix yours as well. It's a fun game for sure. Awesome light show on jackpot
