I don't remember there being any third party SMS controllers*, just using Atari/c64/etc controllers if the game didn't need two buttons. There was the Control Stick, but that was first party. It was also pretty weird, with the stick on the right buttons on the left and a big squarish knob on the stick instead of a ball on top or a bat or grip shape. I guess it was supposed to be reminiscent of a kind of gear shift or something. I didn't use mine very much, it was certainly no NES Advantage!

*(in America anyway, might have been different in England or Brazil, where people actually bought the Master System)
