Does anyone know what protocol the Paddle Control uses?

Controller protocol?
Does anyone know what protocol the Paddle Control uses? As far as I know, no Sega consoles supported analog input on the controller ports, so the paddle control probably doesn't use a simple potentiometer system like the Atari 2600's paddle controllers. If anyone has any information on this, please let me know (and update the page accordingly.) ---GerbilSoft 06:35, 29 November 2010 (UTC)
