Hello,
I would like to know which colour wires are responsible for the A & B buttons please?
Thank you.
Sega changed their colors often, and you could even have a third party controller and not know it. Open up the pad and trace the wires to the buttons.
A & B buttons use the same wire, which you might have figured out if you'd read my dated and more or less incomprehensible page (http://www.gamesx.com/controldata/gencont.htm) on gamesx.com.
