Hello!
I am planning to build a supergun (with a jamma harness) but I don't want to use joysticks.
I have only found blueprints/adaptors for the genesis joypad. But I want to use PS2, Saturn or Dreamcast joypads (without modding them).
I think it will be a little tricky to connect the modern joypads with the basic jamma interface so a prefabricated product would be nice.
Regards Hans
