The Neo Geo (Japanese: ネオジオ Hepburn: Neojio) is really a cartridge-based arcade system board and home video game console launched on January 31, 1990 by Japanese game company SNK. Although it's a member of the fourth generation of video game consoles, it's the first system in the Neo Geo family, which ran through the 1990s before being revived in December 2012 with the Neo Geo By handheld and home system.

The MVS (Multi Video System), as the Neo Geo may the coin-operated arcade game industry, offers owners the ability to place up to six different arcade titles into a single cupboard, a key economic consideration for operators with limited floorspace. Using its games stored on self-contained cartridges, a game cabinet can be exchanged for any different game title by swapping the game's ROM-cartridge and cupboard artwork. The platform's popular series include Fatal Fury, The Full of Fighters, Metal Slug and Samurai Shodown.

The Neo Geo system can also be a notably costly and technologically uncompromised home console, commonly known today as the AES (Advanced Entertainment System). The Neo Geo had been marketed as 24-bit, though it is technically a parallel processing 16-bit 68000-based system by having an 8-bit Z80 coprocessor.

Neo Geo hardware production lasted seven many years, discontinued in 1997; and game software production lasted fourteen many years, discontinued in 2004. In 2009, the Neo Geo was ranked 19th from the 25 best video game consoles of all time by the gaming website IGN. There is an amateur and professional commercial homebrew market for that system.

History

In the four cartridge Neo Geo arcade machine

Initially, the (AES) home system was only readily available for rent to commercial establishments, such as hotel chains, bars as well as restaurants, and other venues. When customer response indicated that some gamers were prepared to buy a US$650 console, SNK expanded sales and marketing to the home console market. The Neo Geo console was officially released on January 31, 1990 in Osaka, Japan. Neo Geo's graphics and sound are largely better than other contemporary home consoles, and the MVS is one of the very powerful arcade units at the time. Furthermore, since the AES had been identical to its arcade counterpart, the MVS, arcade titles released for that home market are perfect translations. Although its high price tag kept it from the mainstream gaming market, it outlasted the market lifespan of the greater popular Sega Mega Drive/Genesis.

In the United States, the console's debut price was planned to become US$599 and included two joystick controllers and a game: possibly Baseball Stars Professional or NAM-1975. However, the price was raised and it is American launch debuted as the Gold System at US$649. 99. Later on, the Gold System was bundled with Magician Lord and Deadly Fury. The Silver System package, launched at US$399. 99, includes one joystick controller and doesn't include a game. Other games were launched at about US$200 or more. At double or quadruple the competition, these premium prices made the console accessible and then a niche market.

Several home console systems were created in line with the same hardware as the arcade games, as well as a number of handheld systems under the Neo Geo brand. These systems range from the following: Hyper Neo Geo 64 arcade system, Neo Geo COMPACT DISC, Neo Geo Pocket, Neo Geo Pocket Color, and Neo Geo By. The most recent, the Neo Geo X, is an officially licensed device with an accumulation of Neo Geo AES games pre-installed.

When realtime 3D graphics became standard in the arcade industry, the Neo Geo's 2D hardware was not able to do likewise. The last official game by SNK for the actual Neo Geo system, Samurai Shodown V Special, was released within 2004. SNK ceased to manufacture home consoles by the finish of 1997, but continued to release games for both arcade as well as home for another eight years.

Measured from the introduction from the arcade hardware in 1990 to the release of the final official home cartridge in 2004, the Neo Geo enjoyed the primary software production lifespan of fourteen years, and a equipment production lifespan of seven years. On August 31, 2007, SNK halted offering maintenance and repairs to Neo Geo home consoles, handhelds, as well as games.

Reception

In a 1993 review, GamePro gave the Neo Geo the "thumbs up". Though they voiced several criticisms, noting that the machine was not as powerful as the soon-to-launch 3DO and had few releases that have been not fighting games, they generally praised both the hardware as well as games library, and recommended that gamers who could not pay the console (which was still priced at $649. 99) play the games within the arcade.

In 2009, the Neo Geo was ranked 19th from the 25 best video game consoles of all time by the gaming website IGN.

Technical details :

An early revision Neo Geo AES motherboard.

Every joystick controller is 280mm (width) × 190mm (depth) × 95mm (height) ( 11 × 8 × two. 5 in. ) and contains the same four-button layout since the arcade MVS cabinet.

The arcade machines have a memory card system by that a player could save a game to return to at another time and could also be used to continue play on the SNK home console from the same name.

The arcade version of the video game hardware is also known as the "MVS, " or Multi Video System (available in 1-slot, 2-slot, 4-slot, as well as 6-slot variations, differing in the amount of game cartridges loaded to the machine at the time), with its console counterpart referred to since the "AES", or Advanced Entertainment System. Early motherboard revisions contain daughterboards, accustomed to enhance the clarity of the video output.

The MVS as well as AES hardware can execute identical machine code. Owners can move EPROMs in one type to the other, and the game will still operate. The program specifics for both MVS and AES game choices are contained on every game ROM, whether the cartridge is supposed for home or arcade use. However, the arcade and home cartridges do possess a different pinout. They were designed this way to prevent arcade operators from purchasing the cheaper home carts and then using them in arcades. It's been found that in a few home version games, one could unlock the arcade version from the game by inputting a special code.

ROM sizes and new venture screens

The original specification for ROM size is up in order to 330 megabits, hence the system displaying "MAX 330 MEGA PRO-GEAR SPEC" on startup. While no technical advances were required to achieve this, some games over 100 megabits, such as Top Hunter, adopted this screen by displaying an animation proclaiming "THE 100MEGA SURPRISE! ". The original ROM size specification was later enhanced upon cartridges with bank switching memory technology, increasing the maximum cartridge dimension to around 716 megabits. These new cartridges also cause the machine to display "GIGA POWER PRO-GEAR SPEC" upon startup or throughout attract mode, indicating this enhancement.

Display

The SNK custom video chipset allows the machine to draw sprites in vertical strips which are 16 pixels broad, and can be 16 to 512 pixels tall; it can draw up to 96 sprites per scanline for a total of 380 sprites on the screen at any given time. Unlike most other video game consoles of its time, the Neo Geo doesn't use scrolling tilemap background layers. Instead, it has a solitary non-scrolling tilemap layer called the fix layer, while any scrolling layers rely exclusively on drawing sprites to produce the scrolling backgrounds (like the Sega Y Board). By laying multiple sprites alongside, the system can simulate a tilemap background layer. The Neo Geo sprite program represents a step between conventional sprites and tilemaps.

Legacy

The Neo Geo may be the first home game console to feature a removable memory greeting card for saved games.

By the mid-1990s, SNK was trying to maneuver onto a new platform, notably the Hyper-64. A Hyper-64 online game called "Fatal Fury: Wild Ambition" was ported to the Ps.

The GameTap subscription service has included a Neo Geo emulator along with a small library of Neo Geo games. In 2007 Nintendo announced that Neo Geo games seems on the Wii's Virtual Console, starting with Fatal Fury: Full of Fighters, Art of Fighting, and World Heroes. Neo Geo games will also be available through Xbox Live Arcade and PlayStation Network, including Deadly Fury Special, Samurai Showdown II, Metal Slug 3, Garou: Mark from the Wolves and The King of Fighters '98.

Home brew activity exists even because the console's discontinuation, both by noncommercial hobbyists and commercially.

Neo Geo includes a community of collectors. Because of the limited production runs received by cartridges between the sizable available arcade library, some of the rarest Neo Geo games can sell for more than $1, 000. The most valuable game is the European AES edition of Kizuna Encounter. The MVS market provides a cheaper option to the expensive and rare home cartridges, and complete arcade kits cost a premium.
