went looking for how to attach the original Atari 2600 Joystick to my Raspberry Pi 2 and found tons of info but can’t find a definitive answer. It seems that there might not be one. I thought purchasing a retro-bit controller adapter that converts the 2600 into a usb connection might do the trick. But .. Nope.. After plugging it into my Pi and doing the configuration setup, I could only set 3 of the 5 values. More research indicates that this is a problem with the controller not following the industry standards.
So, has anyone successfully attached a original 2600 joystick to their PI? I would like to use my paddles for some of the Atari 2600 games as well.
