If you are hacking a joypad (such as a normal computer gamepage/psx gamepad/dreamcast gamepad)... Each button has 2 copper connections... How do you figure out which copper connection is for the ground and for the button press? My controller does not label it so I am at a loss as to which copper connection will be my common ground.
