The Sega Mega Drive is a fourth generation video game console that was released in the very late 80s and very early 90s.
It successed Sega's Master System, and the predecessor to the Sega Saturn.
It was in direct competition to the Super Nintendo Entertainment System and the PC Engine/Turbografx 16.
It was a huge success for Sega, and sported Sega's most famous games, the Sonic the Hedgehog series.
History: The Sega Mega Drive was originally designed to be called the Mega Drive in North America, but due to a copyright issue, had to be named 'Genesis'. It launched with the popular Altered Beast and Sonic the Hedgehog. It was 16 bit, and designed to overpower Nintendo's NES (Nintendo Entertainment System), but ended up being a competitor to the SNES.
Other information: There were a myriad of Sega accessories released for the Mega Drive. The Master System Power Base Converter allowed the Mega Drive to play 8 bit Master System cartridges and Game Cards. The Power Base Converter could only work with the Model 1 Mega Drive. The Sega CD / Mega CD was released for it, allowing the Mega Drive to play CD games. The 32X was released in 1994, and boosted the Mega Drive's power to 32 bit, and allowed the player to play 32X games and Sega Mega CD 32X games.
There were lots of different models of the Mega Drive released. The Model 1 was the first to be released, and had a 3.5mm audio jack in the front of the console, with a volume slider, which allowed for stereo audio. The Model 2 was smaller than the Model 1, and dropped the stereo audio jack. The 32X also required a spacer so that it could be played on the Model 2 without exposing fragile hardware. The Genesis Model 3 was only released in North America, and was very cheap. It could also not use the Sega CD and Sega 32X add on, along with the Master System Power Base Converter. The JVC X'Eye and the Victor Wondermega was released as a machine that could play Mega Drive cartridges and Sega Mega CD games. The Sega Nomad was released as a portable Mega Drive. There were a huge array of games released for the system and it's add ons.
