[QUOTE=Ginnican]Do you know if there's ever been a controller for any game system that has the joystick on the right hand side, and the shooting buttons on the left hand side? [/QUOTE]
Yes. Atari 2600. Also, the Atari 5200 and 7800 (joystick) controllers could be used with either hand because they had buttons on both sides. I think Coleco and Intellivision were also like that, but unfortunately, I've never owned either one.
While it's not a controller, the Atari Lynx portable system lets you play like that. It lets you "flip" the screen upside down and it has a second set of buttons for lefties to play with the joypad on the right and the buttons on the left.
