I've never seen one, and I doubt one exists. Someone probably cut & paste the 4-switch control panel over the original 6-switch picture.
Speaking of the system box, take a good look at the pictures showing people holding what looks like a paddle controller....except that it's not. It's smaller than a paddle, and square-shaped. Also, the cord comes out in the center of it...
Anyone know what the heck these controllers are, and if they actually exist or are simply marketing props?
