In 1990, SNK released a home games console for $649.99. Individual games cost between $200 and $600 each. Adjusted for inflation, that makes the Neo Geo Advanced Entertainment System the most expensive home console ever released — more expensive in real terms than any machine before or since.
It wasn’t a gimmick. It wasn’t overpriced for what it was. The Neo Geo was, quite literally, an arcade machine in a box. The hardware inside the home console was identical to the MVS arcade boards sitting in cabinets around the world. When you bought Metal Slug for the Neo Geo AES, you were buying the arcade game, running on arcade hardware, in your living room. Nobody else was offering that. Nobody else could.
This is the complete guide to the Neo Geo — the hardware, the formats, the games, and the best ways to experience it in 2026.
Understanding the Formats
The Neo Geo is unusual because it existed in multiple formats simultaneously, all running identical hardware. Understanding the differences is essential before spending any money.
The MVS — Multi Video System (Arcade)
The MVS was the arcade version, released in 1990. Arcade operators could install between one and six game cartridges in a single cabinet and swap them out as demand changed — a revolutionary concept that made the Neo Geo extremely popular with arcade owners. A single MVS cabinet could become six different machines. The hardware ran until 2004, making it one of the longest-supported arcade platforms in history.
MVS cartridges are physically larger than AES cartridges and not directly compatible with the home console without an adapter. The key fact for collectors: the games themselves are identical. The same ROM data runs on both formats. MVS cartridges are significantly cheaper than their AES equivalents — most titles run £20–200 on MVS versus £100–5,000+ on AES — which makes the MVS the sensible entry point for anyone who wants to play rather than display.
The AES — Advanced Entertainment System (Home Console)
The home console version, also released in 1990. SNK initially intended it only for rental in Japanese video game shops, not retail sale — the hardware cost was so high they didn’t believe consumers would buy it outright. They were wrong. Demand was sufficient that SNK launched it at retail, and the AES became one of gaming’s great luxury objects.
The AES is what most people mean when they say “Neo Geo.” The home console with its distinctive black design, the large gold cartridges, the superb joystick controllers. It’s the format collectors chase and the format that commands the highest prices. A working AES console sells for £200–500 on eBay depending on condition. The games are where costs spiral — common fighting games start from £50–100 loose, rarer titles run into hundreds, and the truly scarce AES games can reach thousands.
The Neo Geo CD
Released in 1994, the CD version offered the same library at dramatically lower software prices — CD games cost a fraction of the cartridge originals. The catch is significant: the console used a single-speed CD drive, and loading times on graphically intensive games are genuinely painful. Expecting to load up a King of Fighters title and sitting through several loading screens is an authentic experience, but not always a welcome one.
The CDZ model, released in Japan only, used a double-speed drive and improved matters considerably. If you’re specifically interested in the CD format, the CDZ is the one to target — though it commands a premium and availability in the UK is limited.
The Consolised MVS
A popular option among enthusiasts: an MVS arcade board modified or housed in a case to work with a standard TV and controllers. This gives you true arcade hardware running the cheaper MVS cartridge format, without paying AES prices for software. Quality varies depending on who built the consolised unit — some are professional conversions, others are rough. Worth researching carefully before buying. The UniBIOS firmware, available for both AES and consolised MVS units, adds useful features including region-free play and the ability to switch between AES and MVS modes on the same cartridge.
The Hardware
The Neo Geo’s technical specifications were extraordinary for 1990 and remained competitive for most of the decade. The Motorola 68000 CPU ran at 12MHz — the same processor used in the Amiga and the Sega Mega Drive, but clocked faster. A dedicated Zilog Z80A handled audio. The custom graphics processor could display 380 sprites simultaneously, each up to 512 pixels tall, with 4,096 colours on screen from a palette of 65,536. No other consumer hardware came close.
The cartridges themselves were enormous by the standards of the era — later titles pushed up to 716 Mbit of data, which is why the hardware could run games that looked arcade-perfect while competitors were running compressed, degraded home conversions. When you loaded Samurai Shodown on a Neo Geo, you were loading the complete game. Nothing cut, nothing missing.
Audio was handled by the Yamaha YM2610 — 15 simultaneous channels including FM synthesis, programmable sound, and ADPCM voice samples. The Neo Geo’s audio quality was another area where it simply had no consumer competition in 1990.
The Library — Games Worth Playing
The Neo Geo library of 148 AES titles is one of the most focused in console history. This was not a platform for platformers, RPGs, or sports games. The Neo Geo was, above everything else, a fighting game machine — and the best fighting game machine ever made.
Fighting Games
The King of Fighters series (1994–2003) — SNK’s flagship. Annual team-based fighters that built one of the most passionate competitive communities in gaming, particularly in Latin America, Asia, and the Middle East where KOF rivalled Street Fighter in popularity. KOF ’98 is widely considered the high point.
Samurai Shodown II (1994) — weapon-based fighting at its finest. Slower and more deliberate than KOF, with a distinctive style that nothing else has quite replicated. Still played competitively.
Garou: Mark of the Wolves (1999) — widely regarded as one of the best fighting games ever made. A late-era masterpiece that showed what the hardware could produce when pushed. Available digitally on modern platforms and worth playing by any route possible.
Fatal Fury Special (1993) — the definitive version of SNK’s original flagship series. Terry Bogard became one of gaming’s iconic characters largely through this.
Shooters
Metal Slug series (1996–2002) — run-and-gun games with astonishingly detailed sprite animation that remains impressive today. The first three games are the essentials. Metal Slug 3 in particular is an extraordinary technical achievement and one of the best action games ever made.
Blazing Star (1998) — horizontal shooter, visually spectacular, brilliantly designed. One of the more accessible shooting games in the library.
Puzzle
Puzzle Bobble / Bust-A-Move (1994) — the bubble-shooting puzzle game that defined the genre. Available in many forms but the Neo Geo original is the definitive version. One of the few titles in the library that doesn’t fit the fighting game template — and one of the most important games the platform produced.
Collecting in 2026 — What to Expect
Neo Geo collecting is not for the faint-hearted or the budget-conscious. Prices have risen significantly over the past decade and show no sign of reversing. Here’s an honest picture of what things cost.
AES console: £200–500 for a working unit on eBay. Complete boxed units run considerably higher. Controllers are excellent and generally hold up well.
AES cartridges: Common fighting games start from £50–100 loose. Mid-tier titles run £150–400. The rare stuff — Samurai Shodown 5 Special, Blazing Star, Last Resort — can reach several thousand pounds for a complete boxed copy. Check PriceCharting.com before buying anything.
MVS cartridges: The sensible alternative. Most titles run £20–200. A consolised MVS setup with a good game collection can be assembled for far less than an equivalent AES setup. The games are identical. The purists won’t approve. Everyone else will enjoy perfectly good Neo Geo gaming.
Watch out for fakes: Neo Geo bootleg cartridges are common, particularly for AES. Label quality, board condition, and chip markings are all worth checking. The community at neo-geo.com is knowledgeable and generally helpful for authentication questions.
Modern Ways to Play
Neo Geo Mini
SNK’s official modern hardware comes in two main forms. The Neo Geo Mini (around £60–80) is a compact arcade cabinet replica with a 3.5-inch screen and 40 built-in games including Metal Slug, King of Fighters, Samurai Shodown, and Puzzle Bobble. It can also connect to a TV via HDMI. Controls on the built-in unit are adequate rather than excellent — the optional mini controllers improve the experience considerably for TV play.
The Neo Geo MVSX is a full-size arcade cabinet replica with a 17-inch screen, microswitch joysticks, and 50 built-in SNK classics. At around £400–500 it’s an expensive commitment, but it delivers a genuinely authentic arcade feel at home and is built to a high standard. For anyone who wants the Neo Geo experience without original hardware complications, the MVSX is the premium option.

Digital — Switch, PS4, Steam
SNK has released much of the Neo Geo library digitally across modern platforms. Metal Slug Anthology, the Samurai Shodown NeoGeo Collection, King of Fighters compilations, and Garou: Mark of the Wolves are all available. Prices are reasonable and the emulation is generally accurate. For anyone who wants to play the games rather than own the hardware, this is the most practical and affordable route.
The Neo Geo Pocket Color
Worth a mention separately: the Neo Geo Pocket Color, released in 1999, was SNK’s handheld console and one of the finest handhelds ever made. Its clicky thumbstick is still one of the best directional controls ever put in a portable device. The library is small but excellent — Metal Slug 1st Mission, Samurai Shodown 2, SNK vs Capcom: Match of the Millennium. Hardware and games are increasingly sought after and prices have risen sharply. The Analogue Pocket supports Neo Geo Pocket Color cartridges via an adapter, making it the most practical modern route to the NGPC library.
