The Neo Geo, named after the Greek words for "New World," was a video game platform introduced in 1990 by the Japanese company SNK Corporation. It was first sold in two versions: an arcade system board called the Multi Video System (MVS) and a home console named the Advanced Entertainment System (AES). In 1994, a home console version using CD-ROMs, called the Neo Geo CD, was released. The MVS arcade system had multiple slots for game cartridges that could be swapped out, a feature that made it different from other arcade machines of the time, which only played one game at a time. This design helped it become popular with arcade owners.

The Neo Geo was advertised as the first 24-bit system. Its central processing unit (CPU) was a 16/32-bit 68000 with an 8-bit Z80 coprocessor, and its graphics processing unit (GPU) used a 24-bit data bus for images. When it was released, it was more powerful than any other video game console available at the time. It remained stronger than many arcade systems, including Capcom’s CPS, until 1993 when Capcom released 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. Its high cost made SNK avoid selling it directly to consumers at first. Later, because of high demand, it was released for sale as a luxury console. Adjusted for inflation, it was the most expensive home console ever released, costing $649.99 in 1990, which is about $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 for the two systems were not compatible because they had different sizes, so games were released separately for each version.

The Neo Geo MVS was successful in the 1990s because of its low cost, multiple cartridge slots, and small size. Many popular video game series were made for it, including Fatal Fury, Art of Fighting, Samurai Shodown, World Heroes, The King of Fighters, Twinkle Star Sprites, and Metal Slug. Game development for the platform continued until 2004, making the Neo Geo the longest-supported arcade system ever. The AES had limited sales in Japan and very few in the United States due to its high price for both the console and games. However, it has since become a collectible item with a dedicated fan base. Worldwide, one million MVS arcade units were sold, and 980,000 AES and CD home units were sold combined.

History

The Neo Geo hardware was an improvement of an older SNK/Alpha Denshi M68000 arcade platform used in Time Soldiers in 1987. This platform was later developed into the SNK M68000 hardware used for P.O.W.: Prisoners of War in 1988. Unlike other popular arcade hardware at the time, the SNK/Alpha Denshi system used sprite strips instead of tilemap-based backgrounds. The Neo Geo hardware was mainly designed by Alpha Denshi’s Eiji Fukatsu. He added features like sprite scaling using scaling tables stored in ROM, support for more data on cartridges, and better sound hardware. The system’s hardware specifications were finalized in December 1989.

Takashi Nishiyama left Capcom, where he had created the fighting game Street Fighter in 1987, to join SNK after they invited him. At SNK, he helped develop the Neo Geo. He suggested creating an arcade system that used ROM cartridges like a game console and proposed a home console version. His ideas aimed to make the system more affordable for markets such as 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, which followed Street Fighter. He worked on other fighting game series, including Art of Fighting and The King of Fighters, as well as the run-and-gun video game series Metal Slug.

The Neo Geo was announced and shown on January 31, 1990, in Osaka, Japan. SNK displayed several Neo Geo games at Japan’s Amusement Machine Operators’ Union (AOU) show in February 1990, including NAM-1975, Magician Lord, Baseball Stars Professional, Top Player’s Golf, and Riding Hero. The system made its overseas debut 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 system was only available for rent to businesses like hotels, bars, and restaurants. After customer interest showed some gamers wanted to buy the console for $650, SNK expanded sales and marketing for the home console in 1991.

The Neo Geo’s graphics and sound were better than other home consoles, computers like the X68000, and even some arcade systems. Unlike earlier systems, the Neo Geo AES was designed to match the quality of the arcade MVS system. The MVS was one of the most powerful arcade units at the time, allowing game ROMs to be loaded from interchangeable cartridges instead of using custom hardware for each game.

In the United States, the console’s initial price was planned to be $599, including two joystick controllers and a game: either Baseball Stars Professional or NAM-1975. However, the price increased, and the American launch debuted as the Gold System at $649.99 (equivalent to $1,536 in 2025). Later, the Gold System was bundled with Magician Lord and Fatal Fury. The Silver System, priced at $399.99, included one joystick controller and no pack-in game. Other games cost about $200 or more. At twice or four times the price of competitors, the console and games were only available to a small group of buyers. However, its full compatibility with the MVS system meant no extra costs for porting or marketing, as MVS’s success automatically supported the AES, making the console profitable for SNK.

In January 1991, Romstar released an arcade conversion kit version of the Neo Geo in the United States, allowing arcade cabinets to be turned into Neo Geo systems. The same month, the Neo Geo home console debuted in North America at the Consumer Electronics Show (CES). SNK announced that Neo Geo games would typically be released for the home system about six months after their arcade versions.

When real-time 3D graphics became common in arcades, the Neo Geo’s 2D hardware could not produce them. Despite this, Neo Geo arcade games remained profitable through the mid-1990s. The system was one of three 1995 recipients of the American Amusement Machine Association’s Diamond Awards, which are based only on sales achievements. In 1994, SNK created a new home console called the Neo Geo CD. In 1997, a new arcade system called Hyper Neo Geo 64 was released. However, these systems had low popularity and few games.

Although SNK stopped making home consoles by the end of 1997, it continued developing software for the original 2D Neo Geo. Even though the system was old by the end of the decade, it still received popular releases, such as The King of Fighters 2002. The last official game for the Neo Geo system, Samurai Shodown V Special, was released in 2004, 14 years after the system’s introduction.

On August 31, 2007, SNK stopped providing maintenance or repairs 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 in.) and includes a layout with four buttons, the same as the arcade MVS cabinet.

The arcade machines use a memory card system that allows players to save a game and return to it later. These memory cards can also be used to continue playing the same game on the SNK home console.

The arcade version of the video game hardware is called the "MVS," or Multi Video System. It comes in different versions: 1-slot, 2-slot, 4-slot, and 6-slot, which determine how many game cartridges are loaded into the machine. The home 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 output.

The MVS and AES hardware can run the same machine code. Players can move EPROMs (special memory chips) from one system to the other, and the game will still work. Every game ROM (a type of memory chip) contains the program details for both the MVS and AES versions, whether the cartridge is for home or arcade use. However, arcade and home cartridges have different pinouts (the way the connectors are arranged). This design prevents arcade operators from using cheaper home cartridges in arcades. In some home versions of games, players can unlock the arcade version by entering a special code.

The original specification for ROM size was up to 330 megabits. This 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 called "The 100Mega Shock!" after the startup screen. Later, cartridges with bank switching memory technology allowed the maximum ROM size to increase to about 716 megabits. These updated cartridges caused the system to display "Giga Power Pro-Gear Spec" during startup or when showing attract mode visuals, showing this improvement.

The system uses seven specialized processors that share the work of handling visuals, audio, and gameplay.

On-board ROM: 512 KB

The SNK custom video chipset allows the system to draw sprites (moving images) in vertical strips of tiles (blocks of 16×16 pixels) that can be 32 tiles tall (totaling 512 pixels). The system can display up to 380 sprites on the screen at once, but only 96 sprites can appear on each scanline (a single line of the screen). Each tile can be assigned a palette (a set of 15 colors, including transparency). With up to 256 palettes active at the same time, the system can display 3840 colors together. Unlike most other video game 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 layers rely only on drawing sprites to create the illusion of movement, similar to the Sega Y Board. By placing multiple sprites next to each other, the system can simulate a tilemap background. The Neo Geo's sprite system represents a step between traditional sprites and tilemaps.

The onboard Yamaha YM2610 sound chip provides 14 channels of sound.

Reception

The Neo Geo MVS was very successful when it was first released in arcades worldwide. It became one of the most profitable machines in many arcades 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 was number one, World Heroes was number two, and King of the Monsters 2 was number ten. The Neo Geo MVS won 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 (alongside Street Fighter II: Champion Edition, Mortal Kombat, and Terminator 2) and again in 1993. In 1994, the Neo Geo MVS was 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." While they noted some problems, such as the system not being as powerful as the soon-to-launch 3DO and having few games that were not fighting games, they praised the hardware and game collection. They recommended that people who could not afford the console (which cost $649.99) play the games in arcades instead.

The Neo Geo was the first home game console to include a removable memory card for saving game progress.

The GameTap subscription service has included a Neo Geo emulator and a small 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 on PlayStation 3), including 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 later available 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 also included Neo Geo games during its early years.

After the console was no longer produced, people began creating new games for it, both as a hobby and for sale.

The Neo Geo has a group of collectors who value its games. Because only a 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 less expensive option than the rare home cartridges, and complete arcade kits are more expensive. MVS cartridges, which are usually cheaper, can be played on the AES home system with special 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, such as devices with built-in games created by SNK and officially licensed companies.

The Neo Geo X, a device with pre-installed Neo Geo games, was first released in 2012 by TOMMO Inc. After one year, it received little interest due to its high price and poor game performance. On October 2, 2013, SNK Playmore ended the license agreement and ordered the immediate stop of selling the device.

On June 9, 2018, SNK announced the Neo Geo Mini, a small, portable arcade cabinet that looks like the original 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 versions from the original home console, with 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 screen, can connect to a TV via HDMI, and includes ports for external control pads based on the Neo Geo CD controllers.

An international version of the Neo Geo Mini was released outside Japan on October 15, 2018, and 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. SNK stopped selling both versions in July 2019.

In December 2018, a limited-edition Christmas-themed Neo Geo Mini was released, featuring nine games not included in other versions. On June 27, 2019, a limited-edition "Samurai Shodown" version was released in white, red, blue, and later a black edition. This version includes 40 games, all Samurai Shodown titles, and three new games. Another limited edition, called "Samurai Spirits Kuroko," was released in Japan on September 30, 2019, with 48 games.

In September 2019, SNK announced the Neo Geo Arcade Stick Pro, a large white arcade stick with a joystick and 8 buttons. It includes 20 built-in games and can connect to a TV via HDMI. It works with Neo Geo Mini units using an included adapter and is compatible with older Mini game pads. SNK later added more games through software updates, increasing the total to 40.

In November 2020, a special Christmas edition of the Neo Geo Arcade Stick Pro was released. It includes a Neo Geo CD-style control pad, a cover for the 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 released the Neo Geo MVSX, an arcade table system that plays MVS and AES games pre-installed on the device. It supports two players, has a 17-inch screen, and includes 50 games. A 32-inch stand is also available to make it look like a vintage MVS cabinet. It was released in North America in November 2020.

In late 2023, Unico released another Neo Geo Mini designed like an MVS arcade cabinet. It could be bought with or without an additional red controller and an HDMI cable. It includes 45 pre-loaded games, most of which match the MVSX, but five games were 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 both composite and HDMI video outputs. Replicas of original arcade sticks, gamepads, and memory cards will also be released. Ten original Neo Geo games will be reprinted on cartridges 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. These cartridges will work with original AES consoles.
