Just want to ensure it is grounded like this for Jamma. If pin 27 goes to an input, depending on how the super gun handles it, it can cause issues, routing that to video ground. I am not sure if this is your issue, but I have seen boot issues, color issues, etc with using chamma with jamma. Just good to verify.
With nothing plugged into the supergun, pins 27 and 28 should both be ground. I assumed this is handled with the dips.
