The S-S Promoter is a peripheral released by Game Source which allows Super Nintendo Entertainment System (or Super Famicom) controllers to be plugged into a Sega Saturn. Due to Super Nintendo/Super Famicom controllers having one less button than Sega Saturn controllers, there is a switch on the side of the unit that toggles the function of the Super Nintendo/Super Famicom controller's Start button between the Sega Saturn's R and Start buttons.
