The Super Game Boy Commander was a Super Famicom controller that was made for controlling Game Boy games on the Super Game Boy. The controller resembles the bottom of an original Game Boy complete with a fake speaker in the bottom right.
Special functions of the SGB Commander[]
This controller has some special functions that cannot be done with a regular Super Famicom controller. You can slow down Game Boy games with two speed settings, mute the game's audio, and gain direct access to the Super Game Boy colour and border selector. These functions are actually frame perfect macros of the L and R buttons and cannot normally be done by a human without the SGB Commander controller. These special buttons can be toggled back to the standard SNES buttons by flipping the switch in the middle of the controller.
