Hi, I’m new here. I’ve been working on electronics and fight stick mods for a bit but I bumped into a problem I haven’t been able to solve.
I have a Hori Hayabusa that I wanted to put a DB15 port in. I got everything wired up. It works great on PS4. When I hook it up to my supergun though it has some issues.
The stick works correctly.
The Coin button works correctly.
Nothing else works though. I did test everything with a multimeter for continuity and it all looks good.
What seems to be happening is all of the buttons are activating at once in turbo mode.
If I plug in an MVS it immediately pops to the bios screen.
On CPS2 I can manage to trick the game by starting it before plugging in the controller, adding coins, then plugging in. In SFA3 the game will start. Auto pick a character and then go to the first round. Directions all work but nothing else.
I wired everything through the main PCB. I’m sending +5v from DB15 to the main PCB. I’m stumped though. I’d really appreciate any help!
