Instructions
Connect the Retro Duo console to your television via traditional yellow, red and white composite cables or an S-video cable. The S-video mode only works with Super Nintendo games.
Plug the console's power cord into the back of the console. Connect the other end to a power outlet.
Insert the Super Nintendo game cartridge into the front slot and connect the controller to the system. You can use either the controller provided with the system, or original Super Nintendo controllers.
Flip the "on" switch down. The switch is located on the top of the console in front of the cartridge insert. The down position starts the 16-bit Super Nintendo cartridge, while the up position starts the 8-bit NES cartridge. The game will start immediately.
