In computer architecture , 16-bit integers , memory addresses , or other data units are those that are 16 bits (2 octets ) wide. Also, 16-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers , address buses , or data buses of that size. 16-bit microcomputers are microcomputers that use 16-bit microprocessors .
117-1053: The Sega Genesis , known as the Mega Drive outside North America, is a 16-bit fourth generation home video game console developed and sold by Sega . It was Sega's third console and the successor to the Master System . Sega released it in 1988 in Japan as the Mega Drive, and in 1989 in North America as the Genesis. In 1990, it was distributed as the Mega Drive by Virgin Mastertronic in Europe, Ozisoft in Australasia, and Tectoy in Brazil. In South Korea, it

The Z80 processor is primarily used to control both sound chips to produce stereo music and sound effects. Most revisions of the original Genesis contain a discrete YM2612 and a separate YM7101 VDP; in a later revision, the chips were integrated into
351-627: A library of more than 900 games on ROM-based cartridges . Several add-ons were released, including a Power Base Converter to play Master System games. It was released in several different versions, some created by third parties. Sega created two network services to support the Genesis: Sega Meganet and Sega Channel . In Japan, the Mega Drive fared poorly against its two main competitors, Nintendo's Super Famicom and NEC 's PC Engine , but it achieved considerable success in North America, Brazil, and Europe. Contributing to its success
468-483: A "Blood Code". This technicality allowed Sega to release the game with a relatively low MA-13 rating. Meanwhile, the tamer SNES version shipped without a rating. The Genesis version of Mortal Kombat was well-received by gaming press, as well as fans, outselling the SNES version three- or four-to-one, while Nintendo was criticized for censoring the SNES version. Executive vice president of Nintendo of America Howard Lincoln
585-502: A 20- bit or 24-bit segment or selector-offset address representation to extend the range of addressable memory locations beyond what was possible using only 16-bit addresses. Programs containing more than 2 bytes (65,536 bytes ) of instructions and data therefore required special instructions to switch between their 64-kilobyte segments , increasing the complexity of programming 16-bit applications. Bally Manufacturing Bally Manufacturing , later renamed Bally Entertainment ,

An edge connector on the bottom right of the console can be connected to a peripheral. The standard controller features a rounded shape, a directional pad , three main buttons, and a start button. In 1993, Sega released a slightly smaller pad with three additional face buttons, similar to
819-604: A Genesis instead. The SNES debuted against an established competitor, while NEC's TurboGrafx-16 failed to gain traction, and NEC soon pulled out of the market. In large part due to the popularity of Sonic the Hedgehog , the Genesis outsold the SNES in the United States nearly two to one during the 1991 holiday season. Sega controlled 65% of the 16-bit console market in January 1992, the first time Nintendo had not been

Although Katz and Sega of America's marketing experts disliked Sonic , certain that it would not catch on with American children, Kalinske's strategy to place Sonic the Hedgehog as the pack-in game paid off. Sonic the Hedgehog greatly increased
1053-422: A brief venture into the music business with their own record label, Bally Records . Moloney died in 1958, and the company briefly floundered. With the financial failure of its parent company, Bally was bought out by a group of investors in 1963. Throughout the 1960s, Bally continued to dominate the slot machine industry, cornering over 90% of the worldwide market by the end of the decade. In 1964, Bally introduced
1170-507: A controlled room in EA headquarters nicknamed "Chernobyl", to which only one person was allowed access, Mike Schwartz. Schwartz reviewed Sega's copyrighted development manuals and tools, studied the Genesis hardware and games, and wrote original documentation that summarized his findings. The process took him about a month. His work was reviewed by EA's lawyers before being disseminated to Hayes and Nitchals to verify its originality, and subsequently to
1287-735: A line of fitness equipment and clothing owned by FAM Brands , which acquired the name outright in 2013. The rights to use the name for casinos were sold by Caesars in October 2020 to Twin River Worldwide Holdings, which then changed its own name to Bally's Corporation and said that it would rename most of its properties under the Bally's brand. In a related transaction, Bally's Corporation acquired Bally's Atlantic City from Caesars. In January 2022, Caesars announced that Bally's Las Vegas, which they retained, would be rebranded as

The winning submission was a blue hedgehog with red shoes, Sonic , created by Naoto Ohshima , spawning one of the best-selling video game franchises in history. The gameplay of Sonic the Hedgehog originated with a tech demo created by Yuji Naka , who had developed a prototype platform game that involved a fast-moving character rolling in
1521-471: A new partner to market the Genesis in North America and offered the rights to Atari Corporation , which did not yet have a 16-bit system. David Rosen made the proposal to Atari CEO Jack Tramiel and the president of Atari's Entertainment Electronics Division, Michael Katz. Tramiel declined to acquire the new console, deeming it too expensive, and instead opted to focus on the Atari ST . Sega decided to launch

During the late 1970s and early 1980s, Midway was renamed Bally/Midway when it was consolidated with Bally's legacy pinball business. It became a primary source of income for Bally as an early arcade video game maker, obtaining licenses for three of the all-time most popular video games: Space Invaders , Pac-Man , and Ms. Pac-Man . In

One may also see references to systems being, or not being, 16-bit based on some other measure. One common one is when the address space is not the same size of bits as the internal registers. Most 8-bit CPUs of the 1970s fall into this category; the MOS 6502 , Intel 8080 , Zilog Z80 and most others had 16-bit address space which provided 64 KB of address space. This also meant address manipulation required two instruction cycles. For this reason, most processors had special 8-bit addressing modes,
1872-567: A single custom ASIC (FC1004). The back of the Model 1 console provides an RF output port (designed for use with antenna and cable systems) and a specialized 8-pin DIN port, which both provide video and audio output. Both outputs produce monophonic sound; a headphone jack on the front of the console produces stereo sound. On the Model 2, the DIN port, RF output port, and headphone jack are replaced by
1989-474: A stronger name. After reviewing more than 300 proposals, the company settled on "Mega Drive". In North America, the name was changed to "Genesis". Rosen said he insisted on the name as he disliked "Mega Drive" and wanted to represent "a new beginning" for Sega. Sato said some design elements changed, such as the gold "16-bit" wording, in case it was mistaken for yellow. He believed the changes represented different Japanese and American cultural values. Sega released
2106-521: A subsidiary manufacturing video slot machines and other casino equipment. Bally Total Fitness, burdened with debt from over-expansion and declining revenues after the 2008 recession , began selling off its clubs in the 2010s. Sales of large numbers of clubs to LA Fitness in 2011, Blast Fitness in 2012, and 24 Hour Fitness in 2014, along with closures of other clubs saw the chain dwindle. The last Bally Total Fitness club closed in October 2016. The Bally Total Fitness name had been used under license for
2223-555: A successor to the Master System almost immediately after that console launched. In 1987, Sega faced another threat to its console business when Japanese computer giant NEC released the PC Engine amid great publicity. To remain competitive against the two more established consumer electronics companies, Ishikawa and his team decided they needed to incorporate a 16-bit microprocessor into their new system to make an impact in
2340-538: A technical protection mechanism into a new edition of the Genesis released in 1990, referred to as the Genesis III. This new variation of the Genesis included a code known as the Trademark Security System (TMSS), which, when a game cartridge was inserted, would check for the presence of the string "SEGA" at a particular point in the memory contained in the cartridge. If the string was present,
2457-805: A two-part approach to build sales. The first part involved a marketing campaign to challenge Nintendo head-on and emphasize the more arcade-like experience available on the Genesis, with slogans including "Genesis does what Nintendon't". Since Nintendo owned the console rights to most arcade games of the time, the second part involved creating a library of recognizable games which used the names and likenesses of celebrities and athletes, such as Pat Riley Basketball , Arnold Palmer Tournament Golf , James 'Buster' Douglas Knockout Boxing , Joe Montana Football , Tommy Lasorda Baseball , Mario Lemieux Hockey , and Michael Jackson's Moonwalker . Nonetheless, Sega struggled to overcome Nintendo's presence in consumers' homes. Tasked by Nakayama to sell one million units within

In 1994, Sega started the Sega Channel , a game distribution system using cable television services Time Warner Cable and TCI . Using a special peripheral, Genesis players could download a game from a library of fifty each month and demos for upcoming releases. Games were downloaded to internal memory and deleted when
2691-512: A well-regarded soundtrack. ASCII Entertainment reported in early 1993 that Genesis had 250 games versus 75 for the SNES, but limited shelf space meant that stores typically offered 100 Genesis and 50 SNES games. The NES was still the leader, with 300 games and 100 on shelves. Sega's advertising positioned the Genesis as the cooler console, and coined the term blast processing , an obscure and unused graphics programming method, to suggest that its processing capabilities were far greater than those of

The Genesis produces sound using
2925-416: Is sometimes called 16-bit because of the way it handles basic arithmetic. The instruction set was based on 32-bit numbers and the internal registers were 32 bits wide, so by common definitions, the 68000 is a 32-bit design. Internally, 32-bit arithmetic is performed using two 16-bit operations, and this leads to some descriptions of the system as 16-bit, or "16/32". Such solutions have a long history in

By the mid-1980s, Bally again had a strong balance sheet and began buying other businesses, including the Six Flags amusement park chain in 1982, the Health and Tennis Corporation of America (which became Bally Total Fitness ) in 1983, and Scientific Games, a lottery terminal company, in 1986. That year, they also purchased several casinos, including

The Intel 8088 was binary compatible with the Intel 8086, and was 16-bit in that its registers were 16 bits wide, and arithmetic instructions could operate on 16-bit quantities, even though its external bus was 8 bits wide. 16-bit processors have been almost entirely supplanted in the personal computer industry, and are used less than 32-bit (or 8-bit) CPUs in embedded applications. The Motorola 68000

Although experiencing increased sales, Sega decided to recall Night Trap and re-release it with revisions in 1994 due to the congressional hearings. After the close of these hearings, video game manufacturers came together to establish the rating system that Lieberman had called for. Initially, Sega proposed
3627-491: The Sega Saturn . In the early 1980s, Sega Enterprises, Inc. – then a subsidiary of Gulf+Western – was one of the top five arcade game manufacturers active in the United States, as company revenues surpassed $ 200 million between July 1981 and June 1982. A downturn in the arcade business starting in 1982 seriously hurt the company, leading Gulf+Western to sell its North American arcade manufacturing organization and

It later added this file to the games HardBall! , Star Control , Mike Ditka Power Football , and Turrican . In response to the creation of these unlicensed games, Sega filed suit against Accolade in
4095-520: The zero page , improving speed. This sort of difference between internal register size and external address size remained in the 1980s, although often reversed, as memory costs of the era made a machine with 32-bit addressing, 2 or 4 GB, a practical impossibility. For example, the 68000 exposed only 24 bits of addressing on the DIP , limiting it to a still huge (for the era) 16 MB. A similar analysis applies to Intel's 80286 CPU replacement, called

Early 16-bit microprocessors , often modeled on one of the mini platforms, began to appear in the 1970s. Examples ( c. 1973–76) include the five-chip National Semiconductor IMP-16 (1973), the two-chip NEC μCOM-16 (1974),

As a result of the appeal, the Ninth Circuit overturned the district court's verdict and ruled that Accolade's decompilation of the Sega software constituted fair use. The court's written opinion followed on October 20, 1992, and noted that the use of the software was non-exploitative, although commercial. Further,

Positive coverage from magazines Famitsu and Beep! helped to establish a following. Within two days of release, the console's initial production run sold out. However, Sega only managed to ship 400,000 units in the first year. In order to increase sales, Sega released various peripherals and games, including an online banking system and answering machine called

According to Sato, the Japanese design for the Mega Drive was based on the appearance of an audio player, with "16-bit" embossed in a golden metallic veneer to create an impression of power. The console was announced in the June 1988 issue of the Japanese gaming magazine Beep! as the Mark V, but Sega management wanted

5382-657: The November/December timeframe". Nakayama's decision to focus on the Saturn, based on the systems' relative performance in Japan, has been cited as the major contributing factor in this miscalculation. By contrast, Nintendo concentrated on the 16-bit home console market, as well as its successful handheld , the Game Boy , and took in 42% of the video game market dollar share without launching a 32-bit console. Following tensions with Sega Enterprises, Ltd. over its focus on

According to a 2004 study of NPD sales data , the Genesis maintained its lead over the Super NES in the American 16-bit console market. However, according to a 2014 Wedbush Securities report based on revised NPD sales data, the SNES outsold the Sega Genesis in the U.S. market by 1.5 million units. To compete with Nintendo, Sega was more open to new types of games, but still tightly controlled
5616-416: The SNES. A Sony focus group found that teenage boys would not admit to owning an SNES rather than a Genesis. With the Genesis often outselling the SNES at a ratio of 2:1, Nintendo and Sega focused heavily on impression management of the market, even going to the point of deception; Nintendo claimed it had sold more consoles in 1991 than it actually had, and forecasted it would sell 6 million consoles by

However, some sources claim that the console sold 40 million units during its lengthly lifespan. Of these, 3.58 million were sold in Japan, and sales in Europe and the U.S. are roughly estimated at 8 million and 18–18.5 million as of June 1997 (at which time Sega

Nevertheless, the Mega Drive was unable to overtake the venerable Famicom and remained a distant third in Japan behind Nintendo's Super Famicom and NEC's PC Engine throughout the 16-bit era. Sega announced a North American release date for the system on January 9, 1989. At the time, Sega did not possess a North American sales and marketing organization and was distributing its Master System through Tonka . Dissatisfied with Tonka's performance, Sega looked for

The American publisher Electronic Arts (EA) sought a better deal, but met resistance from Sega. They decided to reverse-engineer the Genesis, using a clean-room method similar to the method Phoenix Technologies had used to reverse-engineer the IBM Personal Computer BIOS around 1984. The process began in 1989, led by Steve Hayes and Jim Nitchals. They created

After manufacturing munitions and airplane parts during World War II , Bally Manufacturing Corporation continued producing innovations in flipperless pinball machines, bingo machines, payout machines and console slot machines through the late 1950s. They also designed and manufactured vending machines and established a coffee vending service. Additionally, they made
7488-465: The court found that the trademark infringement, being required by the TMSS for a Genesis game to run on the system, had been inadvertently triggered by a fair use act and was the fault of Sega for having caused false labeling. Ultimately, Sega and Accolade settled the case on April 30, 1993. As a part of this settlement, Accolade became an official licensee of Sega, and later developed and released Barkley Shut Up and Jam! while under license. The terms of
