Mega Drive 4

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 October 2009 as a follow-up to the Mega Drive 3. The first version had 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 in a traditional Mega Drive, plus a guitar accessory for playing the Guitar Idol game, which is overtly based upon the Guitar Hero games.

The game Pense Bem is said to count as 10 games in the general counting.
