The Neo Geo (Greek for "New World"), named NEO•GEO, is a video game platform released in 1990 by the Japanese company SNK Corporation. It was first introduced in two formats: an arcade system board called the Multi Video System (MVS) and a home video game console called the Advanced Entertainment System (AES). In 1994, a version of the home console that used CD-ROMs, called the Neo Geo CD, was released. The MVS arcade system had multiple cartridge slots that allowed games to be swapped out, a feature that made it different from other arcade machines of the time, which had only one game per machine. This helped make it popular among arcade owners.
The Neo Geo was advertised as the first 24-bit system. Its main processor was a 16/32-bit chip called the 68000, paired with an 8-bit chip called the Z80, and its graphics processor used a 24-bit data bus. When it was released, it was one of the most powerful video game systems available. It outperformed many other arcade systems, including Capcom’s CPS, which did not match its performance until 1993 with the CP System II.
The Neo Geo AES was first sold only as a rental console for video game stores in Japan, called the Neo Geo Rental System. High production costs prevented SNK from selling it for retail at first. Later, due to strong demand, it was released for sale as a luxury console. Adjusted for inflation, it was the most expensive home video game console ever released, costing $649.99 in 1990 (equivalent to $1,540 in 2025). The AES had the same hardware as the MVS, allowing home users to play games exactly as they appeared in arcades. However, the cartridges used for the two systems were not interchangeable because they had different sizes, so games were released separately for each platform.
The Neo Geo MVS was popular in the 1990s because of its low cost, multiple cartridge slots, and small size. Many successful video game series were released for the platform, including Fatal Fury, Art of Fighting, Samurai Shodown, World Heroes, The King of Fighters, Twinkle Star Sprites, and Metal Slug. Game software production for the MVS continued until 2004, making it the longest-supported arcade system in history. The AES had a small market in Japan, but sales in the United States were very low because of its high price for both the console and games. Over time, it has become a collectible item. Worldwide, one million MVS units were sold, and 980,000 AES and CD units combined were sold.
History
The Neo Geo hardware was developed from an older SNK/Alpha Denshi M68000 arcade platform used in the game Time Soldiers in 1987. This platform was later improved for P.O.W.: Prisoners of War in 1988. Unlike other arcade systems of the time, the SNK/Alpha Denshi hardware used sprite strips instead of tilemap-based backgrounds. The Neo Geo hardware was created by Alpha Denshi’s Eiji Fukatsu, who added features like sprite scaling using special tables stored in ROM, support for more data on cartridges, and better sound hardware. The system’s final hardware design was completed in December 1989.
Takashi Nishiyama left Capcom after creating the fighting game Street Fighter in 1987. He joined SNK, where he helped develop the Neo Geo. He suggested using ROM cartridges, like those in game consoles, for the arcade system and proposed a home console version. His goal was to make the system more affordable in regions like China, Hong Kong, Taiwan, Southeast Asia, Central America, and South America, where selling arcade games was difficult due to piracy. Nishiyama also created the Fatal Fury fighting game series as a follow-up to Street Fighter. He worked on other fighting game series, such as Art of Fighting and The King of Fighters, and the Metal Slug run-and-gun series.
The Neo Geo was announced and shown on January 31, 1990, in Osaka, Japan. At Japan’s Amusement Machine Operators’ Union (AOU) show in February 1990, SNK displayed games like NAM-1975, Magician Lord, and Baseball Stars Professional. The system made its first appearance outside Japan at Chicago’s American Coin Machine Exposition (ACME) in March 1990. It was released in Japan on April 26, 1990. At first, the AES home console was only available for rent to businesses like hotels and restaurants. After seeing demand, SNK began selling the console to consumers in 1991 for $650.
The Neo Geo’s graphics and sound were better than most home consoles, computers, and even some arcade systems of the time. The Neo Geo AES was designed to match the quality of the arcade MVS system, which used interchangeable cartridges instead of custom hardware for each game. The MVS was one of the most powerful arcade systems of its era.
In the United States, the Neo Geo was originally planned to cost $599, including two joysticks and a game. However, the price increased to $649.99 (about $1,536 in 2025) for the "Gold System" package, which included Magician Lord or Fatal Fury. A cheaper "Silver System" package later sold for $399.99 and included only one joystick and no game. Other games cost around $200 or more. Despite being much more expensive than competitors, the Neo Geo’s full compatibility with arcade games made it profitable for SNK.
In January 1991, Romstar released a kit in the U.S. that allowed arcade cabinets to be converted into Neo Geo systems. The same month, the Neo Geo home console debuted at the Consumer Electronics Show (CES). SNK announced that home versions of Neo Geo games would typically be released about six months after their arcade releases.
When 3D graphics became common in arcades, the Neo Geo’s 2D hardware could not produce them. However, Neo Geo arcade games remained profitable until the mid-1990s. In 1995, the system won one of three Diamond Awards from the American Amusement Machine Association, which recognize top-selling arcade games. SNK later created the Neo Geo CD home console in 1994 and the Hyper Neo Geo 64 arcade system in 1997. These systems were not popular and had few games.
SNK stopped making home consoles by 1997 but continued developing games for the original Neo Geo. Even though the system was old by the late 1990s, it still had popular releases like The King of Fighters 2002. The last official Neo Geo game, Samurai Shodown V Special, was released in 2004, 14 years after the system’s launch.
On August 31, 2007, SNK stopped providing repairs or maintenance for Neo Geo home consoles, handhelds, and games.
Technical specifications
Each joystick controller measures 280 mm (width) × 190 mm (depth) × 95 mm (height) (11 × 8 × 2.5 inches) and has the same four-button layout as the arcade MVS cabinet.
The arcade machines use a memory card system that allows players to save their progress and later return to the game or continue playing on the SNK home console with the same name.
The arcade version of the video game hardware is called the "MVS," or Multi Video System. It comes in 1-slot, 2-slot, 4-slot, and 6-slot models, which differ based on how many game cartridges are loaded into the machine at once. The console version is called the "AES," or Advanced Entertainment System. Early versions of the hardware included daughterboards, which helped improve the quality of the video display.
The MVS and AES hardware can run the same type of computer code. Players can transfer EPROMs (special memory chips) between the two systems, and the game will still work. Every game ROM (a type of memory chip) contains the same program instructions, whether the cartridge is for home or arcade use. However, the arcade and home cartridges have different pinouts (the way the electrical connections are arranged). This design prevents arcade operators from using cheaper home cartridges in arcade machines. In some home versions of games, players can unlock the arcade version by entering a special code.
The original ROM size limit was up to 330 megabits, which is why the system displays "Max 330 Mega Pro-Gear Spec" when it starts. Some games larger than 100 megabits, like Top Hunter, showed an animation titled "The 100Mega Shock!" after the initial screen. Later, cartridges with bank switching memory technology increased the maximum ROM size to about 716 megabits. These updated cartridges caused the system to display "Giga Power Pro-Gear Spec" when it starts or during attract mode, showing the improvement.
The system uses seven different types of processors to handle tasks like visuals, audio, and gameplay.
On-board ROM: 512 KB
The SNK custom video chipset allows the system to display sprites (moving images) in vertical strips made of tiles (small 16×16 pixel blocks) that can be 32 tiles tall (512 pixels total). Up to 380 sprites can appear on the screen at once, but no more than 96 per scanline. Each tile can use a palette (a set of 15 colors + transparency). With up to 256 palettes active at the same time, the system can display 3840 colors together. Unlike most other consoles of its time, the Neo Geo does not use scrolling tilemap background layers. Instead, it uses a single non-scrolling tilemap layer called the "fix layer." Scrolling backgrounds are created by arranging sprites side by side, similar to the Sega Y Board. This method represents a middle step between traditional sprites and tilemaps.
The onboard Yamaha YM2610 sound chip provides 14 separate sound channels.
Reception
The Neo Geo MVS was very successful when it was first released in arcades worldwide. It became one of the most profitable arcade machines in places like North America and Australia in 1990. In North America, three Neo Geo games were among the top ten highest-selling arcade software conversion kits in December 1992: Art of Fighting ranked first, World Heroes ranked second, and King of the Monsters 2 ranked tenth. The Neo Geo MVS received Diamond awards from the American Amusement Machine Association (AAMA) for two years in a row. These awards recognized it as one of America's top four best-selling arcade machines in 1992 (along with Street Fighter II: Champion Edition, Mortal Kombat, and Terminator 2) and in 1993. In 1994, the Neo Geo MVS became the best-selling arcade printed circuit board (PCB) worldwide.
At the 1990 Gamest Awards, the Neo Geo received a Special Award. At the 1991 AMOA Awards, held by the Amusement & Music Operators Association (AMOA), the Neo Geo won the "Most Innovative New Technology" award.
In a 1993 review, GamePro gave the Neo Geo CD a "thumbs up." They noted that the system was not as powerful as the soon-to-launch 3DO and had few games that were not fighting games. However, they praised the hardware and game library and suggested that players who could not afford the console (priced at $649.99) should play the games in arcades.
The Neo Geo was the first home game console to include a removable memory card for saving game progress.
The GameTap subscription service included a Neo Geo emulator and a collection of Neo Geo games. In 2007, Nintendo announced that Neo Geo games would appear on the Wii's Virtual Console, in partnership with D4 Enterprise, starting with Fatal Fury: King of Fighters, Art of Fighting, The King of Fighters '94, and World Heroes. Neo Geo games were later released on Xbox Live Arcade and PlayStation Network (called NEOGEO Station for PlayStation 3), including titles like Fatal Fury Special, Samurai Shodown II, Metal Slug 3, Garou: Mark of the Wolves, and The King of Fighters '98. Many Neo Geo games were also released on the PlayStation 4, Xbox One, Windows, and Nintendo Switch through the Arcade Archives service under the ACA Neo Geo label. In 2019, Antstream Arcade included Neo Geo games during its early years.
After the console was no longer produced, both hobbyists and companies created new games for it.
The Neo Geo has a group of collectors who value its games. Because few cartridges were made compared to the large number of arcade games available, some rare Neo Geo games can cost more than $1,000. The most valuable game is the European AES version of Kizuna Encounter: Super Tag Battle. The MVS market offers a cheaper way to play games than expensive home cartridges, and complete arcade kits are priced highly. MVS cartridges, which are usually less expensive, can be played on the AES home system using adapters.
In 2009, the Neo Geo was ranked 19th out of the 25 best video game consoles of all time by the website IGN.
Recreated hardware
Since the 2010s, SNK has brought back the Neo Geo in new forms with built-in games, created by SNK and officially licensed third-party companies.
The Neo Geo X, an officially licensed device with a collection of Neo Geo games pre-installed, was first released in 2012 by TOMMO Inc. After one year, the device received little interest because of its high price and poor quality of the game copies. On October 2, 2013, SNK Playmore ended the license agreement and asked for all licensed products to stop being sold or distributed.
On June 9, 2018, SNK announced the Neo Geo Mini, a small, semi-portable arcade cabinet that looks similar to the Japanese Neo Geo MVS. It includes 40 built-in SNK games and was released in Japan on July 24, 2018, to celebrate SNK's 40th anniversary. The games are based on the AES home console versions, which have limited continues. However, the Neo Geo Mini allows players to save and load their progress at any time, with up to four save files per game. It has a 320×224 pixel display, can connect to a TV via HDMI, and includes two ports for external Neo Geo Mini control pads modeled after Neo Geo CD controllers.
SNK also released an international version of the Neo Geo Mini, available outside Japan on October 15, 2018, and later in Japan on November 15, 2018. This version has the same features as the Japanese model but includes 14 different games (including all Metal Slug titles) and a different interface. Together, the two versions include 54 unique SNK titles. On July 19, 2019, SNK announced the end of production for both the original and international versions of the Neo Geo Mini.
In December 2018, a limited-edition Christmas-themed Neo Geo Mini was released, featuring nine games not included in earlier versions. On June 27, 2019, a limited-edition "Samurai Shodown" version was released in three colors (white, red, and blue), with a black version added later. This edition includes 40 games, all of the Samurai Shodown series, and three new games not included in prior versions. Another limited edition, called "Samurai Spirits Kuroko," was released exclusively in Japan on September 30, 2019, and includes 48 games.
In September 2019, SNK announced the Neo Geo Arcade Stick Pro, a large white arcade stick with a joystick and eight buttons. It includes 20 built-in games and HDMI output for TVs. It can also connect to Neo Geo Mini units via an included adapter and is compatible with earlier Mini game pads. Initially, the 20 built-in games were all fighting games, but SNK later added more games through software updates to reach a total of 40.
In November 2020, a special limited-edition Christmas version of the Neo Geo Arcade Stick Pro was released. The package includes a Neo Geo CD-style control pad, a cover for the arcade stick, a ball cover, a sticker sheet, and a Neo Geo 30th anniversary artbook. All 40 games are included and unlocked from the start.
In August 2020, Unico announced the Neo Geo MVSX, an arcade table-top system that can play MVS and AES titles pre-installed on the device. It supports two players, has a 17-inch screen, and includes 50 pre-loaded games. A 32-inch stand is also available, allowing the system to function as a free-standing unit resembling a vintage MVS cabinet. It was released in North America in November 2020.
In late 2023, Unico released another Neo Geo Mini designed to look like an MVS arcade cabinet. It could be purchased with or without an additional Unico red controller (modeled after existing Mini controllers) and an HDMI cable. It includes 45 pre-loaded games, most of which are the same as those on the MVSX, but with five games removed.
In April 2026, SNK and Plaion announced the Neo Geo AES+, a recreation of the original AES hardware using ASIC chips. The system includes options like overclocking, language selection, and display settings. It supports composite and HDMI video outputs (including RGB analog video output) and will be released with replicas of original arcade stick, gamepad, and memory card accessories. Original Neo Geo games will also be re-released in cartridge format, fully compatible with original AES consoles. Ten games will be reprinted for the AES+ launch: Metal Slug, The King of Fighters 2002, Garou: Mark of the Wolves, Neo Turf Masters, Shock Troopers, Samurai Shodown V Special, Pulstar, Twinkle Star Sprites, Magician Lord, and Over Top.
