Classic Game Room reviews the SEGA MASTER SYSTEM controller for the Sega Master System video game console. This controller also works with Master System games played on the Sega Genesis (aka Mega Drive or Megadrive) with the awesome Power Base Converter. It also makes a great replacement controller for the Atari 7800 Prosystem because the controller port is identical and it uses 2 buttons.
