*** NOTE!!! Some Konami games don't have -5V connected, it is useful to connect a 'lamp-type' switch onto this connection to turn it 'off' for certain games. Also, pins S and 15 are connected to a second speaker (-) & (+) of stereo games such as Gyruss. (Obviously, these games do not have a third button for either player connected!)
