However, to play most of the games, and play them well, you would need an additional joystick - an 8-way thumb button top joystick and 4, instead of 3, control buttons. These additional controls could be accomodated by moving the start buttons to the front side of the control panel.
The additional price for a control panel outfitted as described above is $75 - 8-way with thumb button, 4-way, 4 control buttons, trackball, 2 start buttons.
