modding a Saturn pad - what´s the trick?

Post by raiden »

so I got a Saturn back recently, and now I wanted to do the inevitable mod job to use my Neo Geo format joysticks on it. Didn´t want to sacrifice an original pad, used the 3rd party one that was included in the deal. Turns out the thing doesn´t seem to have any common ground line, so I don´t have a clue how to do the mod job, as Neo Geo format requires common ground. Is there something I´ve overlooked, does it work with original Saturn pads?

it works with either of the small sega controllers.
the slightly bigger one is great because the points are so accessible

the 3D (largest) one does not use a common ground.

If you don't need any of the existing circuitry in the pad, you can just cut out the IC, and daisy-chain all the grounds together so that they become a common ground that you can use for the NeoGeo spec. If you only plan to use 3 buttons + Start, you should be able to get away with using the original cable too, just chop the plug end off and stick a DB-15 on it.

But since the cable only has 9 wires, you'll be out of luck if you want 4 buttons + start. You'll have to make your own cable with a 9-core + ground.

cut out the IC? How is that supposed to work with a Saturn? Take a look at this:

I don´t want to attach a Saturn pad to a Supergun, I want to attach a Neo Geo format joystick to a Saturn.

ok, guess I´ll have to sacrifice an original pad, then.

Oh, sorry I understand what you're saying now.

In that case I'm not sure if daisy-chaining the grounds would work if it causes interference during multiple button presses...

Better to use the official pad then.

edit: wait... if you want, you can use the cable/plug from the 3rd party controller, and build your own circuit using this
