mitu is of course absolutley right.
I had a real Apple // in the early 80s and can confirm that quite a lot of games did not have joystick-support at all.
Joysticks were rare and expensive during that period, not everyone had one like in our days ;)
And you had even to open the Apple 2-Case to connect a joystick, the port was on the mainboard :D
Yeah. Remember the CH "Mach III?" Good times....until you broke one of the pins off the connector, lol.
