X-CulT: Atari 5200 Self-Centering and Paddle Controllers (Unreleased)
The self-centering joystick is a miracle for games such as Pac Man, but if only it was released. The joystick was found by Curt Vendel when he dove through a bag of 5200 sticks. The controller got rid of the hood, and replaced it with a plastic joystick.
Gone was the idiotic X/Y potentiometer, and hello spring loaded module!
The paddle controller was a custom made controller, posssibly made for use with the 2600 adapter, along with games such as Pole Position.
