History of the Sega Mega Drive

From Sega Retro


The 1980s was an experimental period for the video game industry, but also one of great importance. At the beginning of the decade dozens of companies were getting in on the video game craze, but by the end, video gaming was often associated with just one name - Nintendo.

With very little competition on the home console front, Nintendo and their Nintendo Entertainment System (or NES for short; the North American version of Japan's Family Computer) had dominated the video game market. In the US they had tied up developers and regulated the industry on their own, and it seemed that nothing could unseat the Japanese powerhouse. But as time moved on, many began to question what the future of Nintendo's system held - arcades were entering their golden age, and a once-revolutionary system was starting to look dated.

A frustrated Sega had had two major attempts at unseating the NES. Once with the noticeably inferior SG-1000, and again with the Sega Master System, which despite having built a following in Europe, had failed to resonate with the Japanese or North American public. But as arcade hardware manufacturers began to create games with more complex visuals and soundscapes than the NES could provide, Sega saw an opportunity for success — using scaled down versions of commonplace arcade components that would fit more easily in a consumer's budget, the plan was to create a console capable of providing a closer arcade experience at home.


Sega began its one and a half year "Mark V" development process shortly after the release of the Master System (a.k.a. Mark IV) in mid-1986. As was now tradition, the Mega Drive was built on Sega's existing Sega Master System hardware to keep manufacturing costs down and make hardware and software backwards compatible; however, there was also a push this time to get the system to succeed Sega's System 1 and System 2 arcade boards. The project was led by Hideki Sato and a team of seven including Taku Matsubara and Masami Ishikawa,[1] the latter having previously been a key player in the production of the Master System, and also the Sega Mark III.

As was the custom at the time, the Mark V was designed with very little input from the software developers within Sega, meaning design was focused more on efficiency - decreasing the workload of the main CPU by delegating tasks to other processors, while maximising graphics performance. For much of its development lifespan, the Mark V was set to be an 8-bit machine, led by features such as Texas Instruments' advances in its "Dual-Port Memory" RAM architecture (which had yet to be implemented in a video game environment). It was also the first video game system to use several new complex circuit designs, including FIFO memory, read/write of one line buffer method for drawing, and interlace display.[2]

After rumours of Nintendo's Super Famicom emerged, a decision was made by Sega's then CEO, Hayao Nakayama to adopt something akin to the company's successful Sega System 16 arcade architecture. While the console was not able to match arcade hardware, Masami Ishikawa was asked by his manager to double the graphic memory capacity to improve the console's performance, so he redesigned the way the timing worked with the memory access 
cycle while minimizing the additional 
circuit size and number of IC pins needed.[3]

Ishikawa originally intended to include more from the Sega System 16 arcade hardware, but had to cut them due to cost restrictions[3].

The biggest hurdle was the size of the chip. We wanted to include enlarging and minimizing capabilities as well as sprite-spinning functionality, but the circuit design was becoming too large to fit on one chip, which would have lowered the production yield rate and hiked up costs, so we had to remove it from the spec. The number of available colors was also limited by the size of the circuit structure.

Masami Ishikawa[3]

It is thought Sato made the casting decision to use a 16-bit processor, as it became apparent that this was the future for Sega's arcade business. By using the Motorola 68000, the most suitable 16-bit processor on the market at the time, Sega was able to recycle designs from its 16-bit arcade boards, as well as use pre-existing knowledge of 16-bit games found elsewhere in the company (although this had its downsides - nobody in Sega's CS Team had worked with a 68000, so they had to be retrained). The 68000 was partially 32-bit, with a 32-bit internal data bus and 32-bit registers. The Z80, being present for Master System compatibility, would be used to process sound while in Mega Drive mode.

Nakayama claims to have officially named the console "Mega Drive", with "Mega" representing superiority over rival machines, and "Drive" representing the speed of the chosen Motorola 68000 processor - the heart of the console. Unfortunately for Sega, the "Mega Drive" trademark could not be registered in North America and had to be replaced with the name "Sega Genesis". The trademark was held by a company known as "Mega Drive Systems", who specialised in creating storage devices for home computers.

While the console managed to have its graphics performance marginally improved on request from Sato, the delay caused by choosing a CPU meant Ishikawa hit a brick wall with his console design. The architecture was not as flexible as desired - the Mega Drive could not easily be expanded, and this presented problems when Sega began development on the Sega Mega-CD a few months down the line. Scaling and rotations of sprites were once planned for the system's "Video Display Processor", but were cut from the specification due to higher production costs. The colour palette was also limited by this turn of events - the VDP was getting too big, making it harder to manufacture and fit on the motherboard.

While not the first home machine to contain a 16-bit processor, the the Mega Drive was the first to print the words "16-BIT" in big, gold lettering onto the console itself, thus starting what is often named as the "bit wars", something featured heavily in advertising campaigns up until the Nintendo 64 in the mid-1990s.

Expandability was an early desire for the Mega Drive, with plans to release not only a CD-ROM attachment (what would become the Mega-CD), but a 2-inch floppy disk drive, a printer, modem (arriving as the rarely-used Mega Modem), keyboard, graphics tablet and vaguely defined "PC interface board"[4]. Sega also suggested the machine could act as a "music tool" and have a "superimpose function" (genlock?)[4]. These peripherals would help turn the system into a low-cost business machine for use in the home, though most of the ideas were shelved after the system went to market.

The revised Sega Mega Drive 2 and all future consoles (bar the Teradrive) were produced by different teams under Hideki Sato. Masami Ishikawa moved back to the company's arcade operations in the early 1990s.



The Sega Mega Drive was first released in Japan on October 29, 1988 with two launch titles, Space Harrier II and Super Thunder Blade, and retailing at ¥21,000. An initial advertising push was fronted by rapper/writer/actor/TV personality Seiko Ito, analogous to the system's ability to "multi-task" (although at launch, the only "task" the console could achieve was playing games).

Life was difficult for Sega; Nintendo's Famicom held a monopoly on the market, while NEC's PC Engine had already established the groundwork for a new "16-bit" generation a year prior, growing ever more popular by the day. From a home computer perspective, the MSX2 was continuing its dominance similar to its predecessor (also still supported at this point), the MSX1. The PC-9800 series line and the still relatively new X68000 were also fighting for the "professional" computer market, though these were out of reach of many Japanese consumers at the time.

Nevertheless the console sold out within two days of launch, shifting 50,000 consoles onto Japanese consumers[5][6].

Most major Japanese developers and publishers of the day were in the pockets of Nintendo, NEC and Microsoft/ASCII, with Sega fighting an up-hill battle from day one. The Mega Drive found itself following the trends of arcade games at the time — shoot-'em-ups — and Sega also tried to woo over home computer developers (especially X68000 developers), establishing strong links with the likes of Toaplan and Telenet Japan, as well as initially gathering interest from Namco and Capcom.

Sega's catalogue of arcade ports kept the system alive, but the talk and subsequent launch of the Super Famicom in late 1990 kept Sega in third place (behind the PC Engine) for most of the generation. The release of SNK's Neo Geo AES may have also had an impact in the console's runnings. However, the situation could have been bleaker, as releases like the Shining games, Langrisser, Puyo Puyo, and the Sega Mega-CD kept the console from fully dropping out early.

By late 1991 2 million Mega Drive consoles had been sold, with Sega releasing a special edition Mega Drive bundle to commemorate the milesetone[7]. Being in a trailing position, it is suspected that Sega were reluctant to release official sales figures going forward, leading to some sources suggesting the 2 million figure represents the total number of consoles[8].

1993 saw the redesigned Mega Drive 2 release priced at ¥12,800[9], coinciding with the launch of the redesigned Mega-CD 2.

The Mega Drive had sold 3,450,000 units by the 20th of March, 1994[10].

The Mega Drive was axed in Japan by the end of 1995, with Sega releasing its last first-party game in December and Compile releasing the last game for the region the following year. Sega were very much keen on backing their Sega Saturn console instead, a move which saw it achieve much greater success than the Mega Drive in the years that followed. The final total of Japanese consoles sold in the region is not known.

North America

The Master System had not sold well in North America, leading to the company's US division, Sega of America, taking a back-seat role as the inexperienced Tonka handled console distribution in the States. But the relationship wasn't working - Tonka were performing even less well than Sega, so for the Mega Drive, Sega sought out a new distributor - Atari Corporation.

Having lost its chance to distribute the NES in the US, David Rosen met with Atari Corp's CEO Jack Tramiel and president of Atari's Entertainment Electronics division, Michael Katz in 1989. Tramiel declined the distribution offer, citing the Mega Drive as being too expensive, and the company instead focused on its 16-bit Atari ST computer. Katz, however, would later join Sega of America as its CEO and oversee the console's launch in the region.

The system was released to test markets in New York and Los Angeles on the 14th August 1989, seeing a national rollout later in the month. Although Sega had struggled against the PC Engine in Japan, the Genesis quickly eclipsed the US-variant, the TurboGrafx-16 and became the number one 16-bit console. About 500,000 consoles had been sold in the US by late 1989[11][12].

The early Genesis game library and marketing campaigns in North America focused on the arcade-at-home stance, although Sega also took the decision to create celebrity-sponsored sports titles (as well as the famed Michael Jackson's Moonwalker), a tactic which proved reasonably successful. Sega also partnered with Disney to create platformers such as Castle of Illusion Starring Mickey Mouse[13] and QuackShot, the relationship running for several years into the mid-90s.

Most notably was Sega's strong ties with Electronic Arts[14], which saw rapid growth on the Mega Drive not least due to John Madden Football. EA stemmed from their history as computer game publishers during this period and turned in to a major player of the video game landscape, eventually becoming the world's largest video game publisher.

Early Genesis consoles had compatibility issues with older televisions lacking vertical hold controls; specifically models by Magnavox, Zenith and Sylvania, all of which were out of production when the Genesis launched. Sega corrected their consoles towards the end of 1990 (also offering a no charge fix if users called their helpline (800-USA-SEGA))[15]. An inability to stablise the picture means the output of all video game consoles using RF would appear to "bounce" or scroll vertically, however advancements in TV technology meant that the vast majority of televisions produced after the early 1980s would never experience this problem. This issue is not unique to the Genesis - the original PlayStation was also reported to have similar issues with older sets.

1 million Genesis consoles were sold in the US during 1990[12].

The Genesis made huge gains over Nintendo during the console's first couple of years, although for many it was assumed that the successor, the Super Nintendo Entertainment System (or Super NES, as it is officially abbreviated by Nintendo), would reclaim its crown upon release. Though this eventually did occur, Nintendo's plans were set back dramatically by the release of Sonic the Hedgehog in June 1991, as well as a wealth of high quality titles and strong advertising campaigns depicting the Super NES, much like the original NES, as the weaker system.

June 1991 also saw the Genesis's price lowered to $149.99[16].

1991 saw the Genesis outsell the Super NES[17] at a rate of 2:1[18], with 1.6 million consoles sold over the year[18] leading to 3 million in total[18]. First-party Genesis games were more frequent and Sega's advertising campaign helped paint a picture of a cheaper, "cool" system aimed at older players, as opposed to the younger audience commonly associated with the Super NES. This came out in focus groups conducted by Sony, where many teenage boys didn't like admitting they owned a Super NES[19].

Though damaged, Nintendo never truly went away - a number of strange Sega marketing blunders during 1994-1995 and the strong support coming from Japan helped the Super NES almost close the distance.

When Nintendo dropped the price of the Super NES from $179 to $149, Sega responded on April 29, 1992, when the price of a Genesis (with Sonic the Hedgehog) was lowered to $129.99. At Summer CES 1992 they went one step further - announcing a bundle-less system at $99.99[20]. There were many price drops over the Summer - the Super NES also went down to $99 and the TurboGrafx-16 to $69, but the aging NES stubbornly stuck with a $79 price point.

The Genesis was the best selling "toy" of Christmas 1992 and Sonic the Hedgehog 2 was the best-selling video game[21]. In regards to the whole year, the figures vary - Nintendo claimed 6.6 million Super NES consoles were sold, bringing the total up to 8.7 million consoles and a 69% share of the market. Sega, however, claimed 4.5 million Genesis consoles sold in 1992[22] with a total of 7.5 million. Both claimed first place[23]. Another metric suggested 10% more Super NES consoles were sold in 1992 than the Genesis, at 5.6 million[19].

While the Genesis had spent its first two years attacking the NES, Sega and their marketing agency Goodby Silverstein & Partners took to the airwaves in early 1993 with a new invention in advertising; "Blast processing" - an idea that the Genesis was a faster console than the Super NES, and therefore superior. This turned out to be a huge hit for Sega and seemingly caused reputational damage to the Super NES machine, to the point where Nintendo eventually paid for two page print advertisements denouncing the concept[24]. Ultimately this led to the Genesis being synonymous with faster and more responsive games, while the Super NES was associated with more colourful graphics and its mode 7 rendering capabilities.

The redesigned Mega Drive 2, which was also referred to as the Genesis (i.e. officially there was no "Genesis 2") is thought to have seen a launch alongside the redesigned Sega CD unit around Summer CES 1993, likely at the beginning of June. While pairs were used at the show, little fanfare was given to the high street release.

5,900,000 Genesis consoles were sold during 1993, 3,000,000 of those in the last four months of the year[25].

1994 saw the launch of the Sega Channel service, allowing customers to download Genesis games through a unique cable television service. It was quite successful, lasting until the summer of 1998.

By late 1994, with the launch of the ill-fated Sega 32X, just under 18 million Genesis systems had been sold[26].

According to the February 1995 edition of Game Players NPD figures suggested the Super NES outsold the Genesis for most of the last six months of 1994 (primarily due to Donkey Kong Country), pushing Sega's market share back to 35%[27]. Sega suggested these figures were due to it traditionally spending less money on marketing during the summer months, and lower-than-expected sales figures for Sonic & Knuckles and NFL '95. They later sent the publication their own figures compiled by TRSTS, suggesting a 55% hardware share for Sega versus 45% for Nintendo, and a 53% versus 47% software share[28].

Sega became disinterested in the Genesis by the mid-90s, focusing instead on the Sega Saturn. It did, however contract Majesco to continue manufacturing Mega Drives in the US through 1997 and 1998, and the few third party developers and first party studios that stayed on board produced games like Vectorman 2 and Sonic 3D: Flickies' Island and many compilations. In an ironic twist of fate, a straight port of Frogger would be the last officially released Mega Drive game released in the country - Frogger had been a series Sega held a license over for much of the 1980s, and coincidentally was one of the last Super NES releases in the region too.

However, while Sega expected a sharp decline in 16-bit sales from 1995-onwards, its $99.99 price point and continued support from developers led to more than 2 million consoles being sold in 1995 (demand exceeding supply once again), 300,000 of which were sold in the November/December timeframe[29].

Sega sold 1.1 million Genesis consoles in 1996, alongside 3 million games.[30]

In the first quarter of 1997, the software-to-hardware ratio of the Genesis was reported at 16:1 (versus the 8:1 for the Super NES)[31]. Two weeks before E3 1997 the price of a Genesis was reduced to $79.99 (with a number of possible pack-ins)[32].

Overall the Genesis stands as Sega's most successful video game console in North America, though its final sales figure is disputed. Nintendo claims 23.35 million Super NES consoles were sold in the whole of North America, with no specific figure for North America, but with Nintendo listing its final United States sales figure as over 20 million. Roughly only 20 million Genesis consoles manufactured by Sega can be accounted for in North America. This generally points to the SNES having outsold the Genesis in North America. According to a revised 2014 NPD data, the SNES outsold the Genesis in the US Market.


Sega did not form any direct distribution channels in Europe until the mid-1990s, so the Mega Drive's launch in Europe was somewhat disorganised. For one, the PAL Mega Drive was delayed - originally set to be released in September 1989[33][34][6], it was pushed back to early 1990[35] (later March, then April[36] - around Easter[37]), first due to a perceived lack of software[35], and later due to manufacturing issues. In the UK, Virgin Mastertronic were aiming to sell the console for less than £150[38], with games priced at around £20[39].

But while the console itself was delayed, the technology arrived in early 1989 in the form of Mega-Tech System arcade cabinets, alongside a small handful of titles available in Japan at the time[40].

Virgin Mastertronic did not begin demonstrating its version of the Mega Drive until at least the 29éme Salon du Jouet de Paris in late January 1990, targeting a September release for France[41], whilst also announcing that European and Japanese Mega Drives would not be compatible with each other[42][43][44], although it was reported[45] to be easily circumvented before the European Mega Drive had even been released. Indeed, converters sprung up almost immediately after the official release[46]. Virgin Mastertronic "launched" the Mega Drive to the European press at the Hôtel de Sully in Paris on the 19th of June[47][48], a few months ahead of the actual release.The firm was also responsible for distribution across the UK, Spain and Germany and was aiming for a similar launch window, while others such as Italian distributor Giochi Preziosi would start selling their stock around November, having introduced the console to Italian audiences at the 1990 SIM-Hi-Fi IVES event between the 20th and 24th of September[49].

In the United Kingdom, the Mega Drive launched on September 14, 1990 during the European Consumer Entertainment Show (ECES) for the price of £189.99 (complete with Altered Beast)[50]. 30,000 units had been pre-ordered prior to this date[51], with Virgin Mastertronic expecting to sell around 40,000 in total by the end of the year[52][53].

Success of the Mega Drive was initially somewhat hard to measure, not least because in much of Europe, there was initially very little interest in the console market. Whereas Japan and North America had opted for dedicated video game consoles during the 1980s, most of Europe was content with home computers, of which 16-bit varieties (the Amiga and Atari ST) had been launched around 1985-1987 and were becoming ever more affordable with each passing month.

Sega's Master System had outperformed its continental rivals by unseating Nintendo's console throne, but initially, the device was not driving the European market, just offering an alternative to customers on a tighter budget. By the end of the 1980s, the Master System was eventually outselling home computers,[54] though this did not necessarily crossover into similar success for the Mega Drive at the time. For many, there was initially no need for the Mega Drive to exist; despite being more powerful for video games, it was viewed as overall less functional than a 16-bit computer, and so was not considered a major player for the months leading up to its official release.

Another factor affecting the figures is that many who were interested in purchasing a Mega Drive had already done so, well in advance of official European launches. So called "grey market" machines had been available since early 1989[55], and would continue to be sold until the official launch in September 1990. NTSC machines were initially imported from Japan (with internal modifications to work on PAL televisions, and power adapters to tackle the 60Hz to 50Hz conversion), before PAL systems began selling in Hong Kong. Virgin Mastertronic refused to offer support for any of these units, claiming the PAL units were faulty anyway[38].

Importing a grey market machine would usually cost between £200 and £250[38] (though sometimes as low as £180[39]), with imported games selling between £30[38] and £50 per game - pricing that turned out to be close to the real thing. Conversions would either see the unit hooked up to a television through scart leads (i.e. RGB, which was not an option on most low end or older television sets of the time), or through RF (which despite the lesser picture quality, would actually cost more due to the compilcations of making it work). The only problem was that when the time came, official UK Mega Drive games would not run on these consoles without adaptors.

There were an estimated 140,000 of these machines already in the UK at launch[51], in turn generating a lot of media coverage over import games during 1989 and 1990. Virgin Mastertronic attempted to address this issue by publishing warnings in the Spring and Summer of 1990, but, similarly to the state of the PC Engine, those seeking the device in an era where consoles were not necessarily mainstream, ignored the official distributor.

Aside from computers, the Mega Drive lacked competition for the first two years of its life. NEC spent most of 1989 and 1990 debating with itself in regards to launching the PC Engine in the region, and the much-hyped Konix Multisystem never made it to production. Other "consolised" computers such as the Amstrad GX4000 and the Commodore 64 GS struggled out of the starting gate and were discontinued within the year. The only established console brands were the Nintendo Entertainment System (which had been losing the fight with the Sega Master System since its late launch in 1987) and the aging Atari 2600 which had been in the UK since 1978 and at this point was selling for as little as £50. The Super NES, while talked about, would not arrive in Europe until 1992.

In Spring 1991, the Mega Drive's price was lowered to £149.99[56][57] in the UK. 85,000 official Mega Drives had been sold in the country around that time[57]. 193,000 consoles were sold across Europe during the first half of 1991[58].

Dedicated home consoles had seen a resurgence during 1988 and 1989, but were still trailing behind 8-bit and 16-bit home microcomputers. This would change with the release of Sonic the Hedgehog in June 1991, as while the initial batch of Mega Drive games had been impressive, Sonic was the first game widely seen to be beyond the capabilities of the current Atari ST and Amiga computers. Sega's success attracted numerous big software houses such as Virgin Games, Acclaim Entertainment and Ocean Software into building a strong portfolio of Mega Drive games.

Not seen were big software publishers such as Renovation Products, which although had built up a large library of Genesis games in North America, failed to find a distributor in Europe after talks with Ubisoft seemingly broke down.

September 1991 saw the Mega Drive be reduced to £129.99 in the UK[59], and like North America, Sonic the Hedgehog became the pack-in game of choice. Similar price reductions occurred across the continent - for a complete list of bundles see Mega Drive consoles in Europe. The year saw the beginnings of a major cultural shift in the European market - the Amiga struggled to match Sonic and its peers, and yet was three or four times the price. Soon Sega's console was the gaming product of choice, and dedicated gaming systems were the new standard bearers.

225,000 Mega Drives were sold in the UK in 1991[60], with 815,000 across Europe as a whole[60].

When the Super NES arrived late in April 1992, it was unable to unseat Sega as the dominant video game force in the UK. Across the continent, however, the picture is more mixed, with Sega leading France and Spain, and Nintendo having an edge in Germany and parts of Scandinavia. Much of this is due to a change in Super NES fortunes with the release of Donkey Kong Country in 1994, as well as Sega shifting focus towards the Sega 32X and Sega Saturn "32-bit" markets.

920,000 and 880,000 Mega Drive units were sold in the UK during 1992 and 1993, respectively (versus 680,000 and 720,000 for the Super NES)[61]. By the end of 1992 there were 1,050,000 Mega Drive consoles in the country[62].

In August 1993 the UK received the redesigned Mega Drive II[63], however unlike its Mega-CD counterpart, the Mega-CD II, the unit saw a staggered launch across the continent - France received theirs in September, but Germany had to wait several weeks and Spain was stuck with the original design until as late as 1995. This led to situations where, depending on where you lived, the Mega-CD II and Sega 32X may have been on sale many months before the Mega Drive II hit the market.

By the end of 1994, 2,500,000 Mega Drive consoles were estimated to have been sold in the UK, versus 1,500,000 Super NES consoles and 2,215,000 Amiga computers[64]. In Germany, the Super NES held the lion's share of the market, with approximately 1.4 million consoles sold versus only 800,000 Mega Drives in the first half of 1995[65].

Mega Drive was officially released in all post-communist countries and became the most popular 16-bit console due to lower price and better availability than the competing Super Nintendo. Unfortunately, the customers often encountered cheaper clones and bootleg copies of the MD hardware and software. Along with PlayStation, Game Boy and Famiclones, Mega Drive became a symbol of video games of the 1990s. The best sales results from that region, Sega had in Russia and the CIS countries[66].

Malcolm Miller said in May 1996 that after decline of Master System, Sega will be pushing the Mega Drive for Greece, Portugal and Eastern Europe because these territories want a low-price product[67][68]. Sega said that the 16-bit consoles will have lion share's here, due to low price on old systems (one third of the 32-bit systems which was around £85 plus taxes) and will dominate the region until 1998[69].

By 1996, there was an installed base of 8 million Mega Drive consoles in Europe.[70] Its final sales figure was over 9 million consoles sold in Western Europe.[71]The final sales figure for Eastern Europe are unknown.

Like North America, the Mega Drive was replaced, perhaps prematurely, by the Sega Saturn and discontinued in 1998 after 8 years in the European market. However, during its half-decade of service had become not only the most successful European console of all time, but had began to change opinions on gaming as a whole. The IBM PC was putting traditional 16-bit computers out of action, with mice and keyboards being favoured over joysticks - games built for joysticks, which had once thrived on machines by Atari, Sinclair, Amstrad and Commodore found themselves on consoles instead.

The Mega Drive also helped launch the hugely popular FIFA series, which continues to exist to this day.

South America

In Brazil, the Mega Drive handled by TecToy, who was also responsible for the Master System's distribution in the country, where, similar to the Master System, it became the system of choice throughout much of the 1990s. TecToy tried to produce a number of original titles in 1996 and following, presumably ending at Show do Milhao 2 (2002), part of a partnership with a popular regional game show. The popularity of the system was so big that in 2000, TecToy sold 100,000 units of Mega Drive, compared to 25,000 units of Dreamcast[72]. The last Mega Drive console was released in 2017, which was finally discontinued in 2023.

In 1992, TecToy got license to distribute Sega products in Argentina, Paraguay and Uruguay.

Sega also sign few distribution deals for Mega Drive in other countries of that region.

South Korea

In South Korea, the console was distributed by Samsung as the Super Gam*Boy (수퍼겜보이), successor the Gam*Boy (Master System). For unknown reasons both were rebranded under the (Super) Aladdin Boy (수퍼알라딘 보이) name within a couple of years, and then when the redesigned console hit the market, the Super Aladdin Boy II (수퍼알라딘 보이II).

By February 1997, Samsung completely exited the gaming business due to the failure of the Samsung Saturn and in the same year, HiCom released Mega Drive 2, now under its original name and re-released some of the games.


From Sega's perspective, everything east of Europe and west of Japan/South Korea is classed as "Asia". This is a very large region and covers dozens of countries, but the markets are generally considered to be quite small as we're dealing with second world and potentially even third world countries. Between 1990 and 1996, Sega entered into deals with distributors in many countries of that region. In 1990, Mega Drive was released in Singapore and then consistently distributed in other South, East and Pacific Asian countries. The Middle East and CIS countries, i.e. the Caucasus, North and Central Asia, were supplied from the Asian and European channels, which means that the models sold there came from these two regions. Quite a big problem for Sega in this region was the piracy of consoles and games, which Sega tried to stop in many ways with different effects. In many countries here, high piracy was a main reason for the popularity of the Mega Drive, because it meant cheaper prices.

Sega expected to sell 3.2 million units of Mega Drive across the Asia.[73]

In India, Sega wanted to sell 100,000-120,000 units per year starting with spring 1995.[74]


Mega Drive was sold in the 90s in Africa and was the most popular of all Sega consoles in the region.


Despite successes in North America and being the console of choice for Europe, Brazil and many smaller markets, the Sega Mega Drive ultimately failed to woo its homeland of Japan, which was the deciding factor when developing the console's successor, the Sega Saturn, which ironically flopped in most regions aside of Japan. Despite this, the Mega Drive is often used to represent Sega's "glory years", with numerous compilations and emulators released by the company since the late 1990s.

The Mega Drive also saw Sega play the console add-on game with the Sega Mega-CD, which impressed gamers in Japan with a rich variety of games released on the new compact disc technology, however overseas, marketing focused on "full motion video" games that continuously failed to impress. Sega also tried various forms of online gaming several times — the first-party Mega Modem and Sega Channel, and third-party XB∀ND. Various other add-ons would be made over the years.

Finally, in a combination of poor communication between Sega of America and Sega of Japan and the desire to keep the Mega Drive afloat, Sega of America released the Sega 32X, an add-on which added its own additional capabilities to the Mega Drive, such as a larger color palette and a two fast CPUs to facilitate higher quality 3D rendering than what was seen on the Mega Drive (which went as advanced as F1 unaided). The 32X was released too late, had manufacturing errors at launch, and was too expensive to impress, and promptly fell flat on its face.

In total, 30 million Mega Drive consoles were sold worldwide

Since January 2005, AtGames has held a license to reproduce legacy Sega hardware[75] and has released a number of Mega Drive "consoles on a chip", some even containing cartridge slots.

Selected Mega Drive games are available through the Wii's Virtual Console service, Xbox Live Arcade and the PlayStation Network. In addition, many PC compilations have been released. The Sega Mega Drive is also a top choice of platform for emulation, with a number of free Mega Drive emulators available to the public. Some, such as KGen are known to have been used by Sega themselves.

In the wake of the 25th anniversary of the Mega Drive's November 1990 UK release, the AtGames Mega Drive (which features built-in games and a cartridge slot) experienced a 400% UK sales surge in November 2015, in the run up to Christmas 2015.[76]
