— Slogan for the Sega Genesis/Mega Drive.

The Sega Mega Drive (メガドライブ Mega Doraibu?) is a video game system released by Sega in the late 1980s. It was a direct competitor of NEC's PC Engine (which was released one year earlier and had a better success in Japan) and the Super Nintendo Entertainment System (which was released two years later). The console has a legacy with certain games available and regarded as the starter of the Sonic the Hedgehog series as well.

Although the Sega Master System was a success in Europe, and later also Brazil, it failed to ignite much attention in the North American or Japanese markets, which, by the mid-to-late 1980s, were both dominated by Nintendo's large market shares.[2][3][4]

The first name Sega considered for its console was the MK-1601, but it ultimately decided to call it the "Sega Mega Drive". The name was said to represent superiority and speed, with the new and powerful Motorola 68000 processor in mind.[5] Sega used the name Mega Drive for the worldwide version of the console. The North American version went by the name "Genesis" due to a trademark dispute.[6]


The Mega Drive was released in Japan on 29 October 1988,[7] almost exactly a year after the release of NEC PC Engine and the same year as the release of TurboGrafx 16 in North America.

In 1987, Sega announced a North American release date for the system (under the name of Sega Genesis) of January 9, 1989.[8] Sega initially attempted to partner with Atari Corporation for distribution of the console in the US, but the two could not agree to terms and Sega decided to do it themselves.[9] Sega was not able to meet the initial release date and United States sales began on 14 August 1989 in New York City and Los Angeles. The Genesis was released in the rest of North America later that year.[10]

The European release was on 30 November 1990. Following on from the European success of the Sega Master System, the Mega Drive became a very popular console in Europe. Unlike in other regions where the Nintendo Entertainment System had been the dominant platform, the Sega Master System was the most popular console in Europe at the time.


In the United Kingdom, the most well known of Sega's advertising slogans was "To be this good takes AGES, to be this good takes SEGA". Some of these adverts employed a rather inappropriate sentences for example, "The more you play with it, the harder it gets" displayed with an illustration of the waggling of a joystick.[11]

Another prominent figure in the European marketing was the "Sega Pirate", a talking one-eyed skull that starred in many TV adverts with a generally edgy and humorous attitude. Since the Mega Drive was already two years old at the release in Europe, the many games available at launch were naturally more in numbers compared to the launches in other regions. The ports of arcade titles like Altered Beast, Golden Axe and Ghouls 'n Ghosts, available in stores at launch, provided a strong image of the console's power to deliver an arcade-like experience.[12]

The arrival of Sonic the Hedgehog in 1991 was just as successful as in North America, with the new Sega mascot becoming popular throughout the continent.[12]

In Brazil, the Mega Drive was released by Tectoy in 1990, only a year after the Brazilian release of the Sega Master System. Tectoy also ran the Internet service Sega Meganet service in Brazil as well as producing games exclusively for the Brazilian market.[13]


Main articles: Sega CD and Sega 32X

The Sega 32X

Sega Mega Drive has two optional add-ons, the Sega CD and Sega 32X. Sega CD plays a high-quality CD-ROM using a slow 1x Optical Disc Drive while increasing audio and visual capabilities over stock Mega Drive.

On the other hand, Sega 32X works as an "enhancement" over a stock Mega Drive console with additional 32-bit processor to process more complex graphical tasks. Sega 32X was released almost the same time as Sega Saturn was released, in 1994.

End of support and third-party licensing

The Mega Drive was supported until 1997 in Europe, when Sega announced it was dropping support for it.[14] It was discontinued along with its predecessor, the long-lived Sega Master System, to allow Sega to concentrate on its newer console, the Saturn. The Mega Drive's add-ons, the Mega CD and 32X, were also both discontinued at this point, having been the same general failures they were in the other regions.[15]

In 1997, Sega licensed the Mega Drive to Majesco so that its could re-release the console.[16] Majesco began re-selling millions of formerly unsold cartridges at a budget price together with the second model of the Genesis, until it later released a third version of it.


Sega Power Base Converter

One of the key design features of the console is its backwards compatibility with Sega's previous console, the Sega Master System. The 16-bit design is based upon the 8-bit design, albeit enhanced and extended in many areas. In order to achieve backwards compatibility, the Master System's central processor and sound chip (the Zilog Z80[17] and SN76489 respectively) are included in the Mega Drive, and the Mega Drive's Video Display Processor (VDP) is capable of the Master System's VDP's mode 4 (though it cannot run in modes 0, 1, 2, or 3).

As the cartridge slot is of a different shape, Sega released the Power Base Converter, a separate device that sits between a Master System cartridge and the Mega Drive's cartridge slot. The Power Base Converter does not contain any Master System components, instead functioning as a pass-through device. The converter contains a top slot for cartridge-based games along with a front slot for card-based games, as well as the 3-D glasses adapter. When a Master System game is inserted, the system puts the Z80 in control, leaving the Mega Drive's main 68000 processor idle.[17]

The only game which does not work with this device is F-16 Fighting Falcon.[18]

Sega Mega Jet

The Sega Mega Jet was another handheld version of the Sega Mega Drive. It was rented for use aboard Japan Airlines flights. The device lacked its own screen but could play Mega Drive cartridges when connected to a small armrest monitor used on Japan Airlines. Four games for the flight were available, including Super Monaco GP, and Sonic the Hedgehog. However, since the unit accepted standard Mega Drive cartridges, passengers could bring in and use their own. The Mega Jet was marketed in Japan as a portable Mega Drive, and was available in limited quantities in department stores.

The Mega Jet eventually became the basis for the Sega Nomad released exclusively in the United States in 1995, a portable Mega Drive with a backlit screen.

Sega Nomad

The Sega Nomad (also called Sega Genesis Nomad or just Nomad) was a handheld game system sold for the North American consumer market which played Mega Drive/Genesis game cartridges. The system was similar to the Japanese Sega Mega Jet, but featured a built-in color screen; the Mega Jet needed a separate monitor.

The Nomad is one of the few Sega systems that can play most games regardless of region without an adapter. Its codename during development was Project Venus, as per Sega's policy at the time of codenaming their systems after planets.

Game library

The Nomad does not have its own game library, but instead plays Genesis games. At the time of its launch, the Genesis had already over 500 games available to play. However, no pack-in title was included for the Nomad. The Nomad can boot unlicensed, homebrew, and bootleg games made for the Genesis.

Some earlier third-party titles have compatibility issues when played on the Nomad, but can be successfully played through the use of a Game Genie. Likewise, due to its lack of compatibility with any of the Genesis' add-ons, it is unable to play any games for the Sega Master System, Sega CD, or Sega 32X. The Nomad employs two different regional lockout methods, physical and software, but methods have been found to bypass these restrictions


  • Japanese Sega Mega Drive cartridges have a different shape and will not fit in either Genesis or PAL region Mega Drive cartridge slot. Japanese Mega Drive systems have a piece of plastic that slides in a place of the cartridge when the power switch is turned on, inserting a Genesis cart will make it impossible to turn on a Japanese MD. Minor modifications to the plastic locks in the systems will bypass the regional locks.
    • However, the console main board was designed with language and frequency jumper sets which originally activated features in the same ROM for the different regions, this feature was later used to enable software-based regional locks that display warning messages that prevent the game from being played. Switches placed instead of the jumpers will bypass the locks.
    • In region-locked games, if there is a multiple language feature, it can be changed with the switches after the game has booted-up.
  • There are over 900 games released for the Mega Drive across seven major regions: Japan, USA, Europe, Australasia, Korea, Asia, and Latin America.
  • The console is mentioned in a couple of songs rapped by "The Game" and "Busta Rhymes".
  • In Lego Dimensions, after Sonic follows Eggman through a portal he battles Robo Sonic, Mecha Sonic, and Metal Sonic. After he is finished fighting Metal Sonic explodes and hits the portal device causing 3 portals to open, and the first model of the Sega Mega Drive flies out one of those portals.
  • JAMMA made an arcade board called the Sega Mega Play in 1991 and it has the ability to play Sega Mega Drive games, such as Sonic the Hedgehog and Sonic the Hedgehog 2. The hardware was released in Asia and the PAL regions, but never made it to North America.[22]
