The Mega Drive 4 (also branded as the Mega Drive 4 Guitar Idol) is a Mega Drive "console on a chip" which was released by Brazilian company Tectoy in 2010 as a follow-up to the Mega Drive 3. It has 87 built-in games, some of which are not Mega Drive titles specifically, and does not have a cartridge slot for playing other games. It also comes with two control pads which attach to the console via two DE-9 ports, as they would a traditional Mega Drive. It also comes with a guitar accessory for playing the Guitar Idol game, which is overtly based upon the Guitar Hero games.
