New Amiga compatible joypads

[matthey]

Now we need to turn the thread into a guide on how to modify these pads to work as 3-button pads, how to add/change the functions of the buttons, and how to prevent them from sending a 5V signal if they do.

The modification should be the same as other 6 button Genesis pads...

I have used unmodified Genesis pads without problems. B is the normal button and C works on some Amiga games. A can be made to work by swapping pins/lines 5 & 7...

The ADoom docs also suggest putting a 470 ohm resistor in...

"A Sega Genesis controller may be use on the Amiga as long
as you swap lines 5 & 7, and put a 470 ohm resistor
between lines 5 & 7."

This allows a 6 button Genesis control pad to function on the Amiga.
