I think this post belongs here?
I had been working on an adapter to connect DB-15/supergun style fightsticks to the SEGA Naomi. After wiring the first DB-15 to the breadboard, I looked at the rats nest and decided to design a PCB instead. So, here it is:

I started with ‘charcole’s JVS code for arduino and adapted it to support two players with 6 buttons, a start, and a coin each. The DB-15 pinout is SNK standard, but with pin 2 and 10 used for button 6 and 5. The adapter pulls 5v from one USB cable and uses a second USB cable for JVS. At this point, everything seems to be working.
The adapter has tested good in 2-player mode with:
SEGA NAOMI:
- Dead or Alive 2
- Moero, Justice Gakuen
- Marvel vs Capcom 2
- Melty Blood: Actress Again
- Radrgy Noa
- Power Stone 2 (2-player mode)
Taito Type X
- Goketsuji Ichizoku Matsuri Senzo Kuyou (service button implemented, but no trace on PCB)
From the pictures, you can see my testing setup is no good for testing lag. There is real possibility that it may work with other JVS systems, but I have not been able to find any to test with.
I have a question though. Would anyone else find this useful? I could sell complete boards, or sell the bare PCB with a parts list. I should probably design a case. I’ve already posted the source code.
