Subject: Atari5200 joystick driver: enable POT input.
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2d4210b3094c7153f6c2cf10a64bff58dc88fd9c;p=cc65

Atari5200 joystick driver: enable POT input.

The "Atari800" emulator doesn't emulate this aspect, therefore the problem
wasn't noticed before.
