I'll start with my setup:
I built this supergun over a year ago. I went for a rather simple design, it features an RGBS out via 8PIN mini DIN, separate audio out, detachable kick harness connector with screw terminals, your usual buttons - TEST & SERVICE, brightness and audio volume pots. Real arcade PSU inside. Instead of the NeoGeo controller ports I used two Sega Saturn converters with a built-in coin mechanism emulator. That's it.
I also designed a different type of supergun that some of you may already be familiar with, it's called HAS (Home Arcade System). It's also pretty simple, but additionally features button layout remapping and autofire.
