Gravis makes both a Game Port and a USB version. On the Mac, any USB controller will work if you have USB Overdrive installed on your computer. USB Overdrive is a shareware utility available here that lets you assign keyboard presses to the controller buttons. How suitable a controller is depends on its configuration. We use the Gravis GamePad Pro USB version .
