The Mega Drive Twin Pads is a Mega Drive "console on a chip" originally produced by AtGames for the Asian market with 5 built-in games and distributed in Europe by Blaze Europe with 10 games. One of the two game controllers plugs directly into a television, however it will only output a PAL signal. There is no cartridge slot, so you are limited to the 10 games. Four AA batteries are needed to operate the console.
