It was initially released in two [[ROM cartridge]]-based formats: an [[arcade system board]] (Multi Video System; MVS) and a [[home video game console]] (Advanced Entertainment System; AES). A [[CD-ROM]]-based home console iteration, the [[Neo Geo CD]], was released in 1994. The arcade system can hold multiple cartridges that can be exchanged out, a unique feature that contrasted to the dedicated single-game [[Arcade cabinet|arcade cabinets]] of its time, making it popular with arcade operators.<ref>{{cite web |date=20 May 2011 |title=SNK Neo-Geo 101: A Beginner's Guide - RetroGaming with Racketboy |url=http://www.racketboy.com/retro/snk-neo-geo-101-a-beginners-guide}}</ref>

The Neo Geo was marketed as the first [[24-bit computing|24-bit]] system; its [[Central processing unit|CPU]] is actually a [[16-bit|16]]/[[32-bit]] [[Motorola 68000|68000]] with an 8-bit [[Zilog Z80|Z80]] [[coprocessor]], while its [[Graphics processing unit|GPU]] chipset has a 24-bit graphics data [[Bus (computing)|bus]]. It was a very powerful system when released, more powerful than any video game console at the time, and many arcade systems such as rival [[Capcom]]'s [[CP System|CPS]], which did not surpass it until the [[CP System II]] in 1993.<ref>{{cite web |title=Neo Geo History |url=http://www.neogeokult.com/articles-us/neo-geo-history/ |url-status=dead |archive-url=https://web.archive.org/web/20121231233202/http://www.neogeokult.com/articles-us/neo-geo-history/ |archive-date=2012-12-31 |access-date=2016-01-25 |website=Neo Geo, Arcade & Retro Games}}</ref>

The Neo Geo AES was originally released solely as a [[rental]] console for video game stores in Japan called the ''Neo Geo Rental System'', with its high manufacturing costs causing SNK not to release it for retail sale. This was later reversed due to high demand and it was released at retail as a luxury console. Adjusted for inflation, it was the most expensive home video game console ever released, costing {{US$|649.99|1991|fmt=eq|round=-1}}.<ref>{{cite web |last=Plunkett |first=Luke |title=36 Years of Console Prices, Adjusted for Inflation |url=http://kotaku.com/36-years-of-console-prices-adjusted-for-inflation-1485353267 |website=[[Kotaku]] |access-date=24 June 2021 |date=December 17, 2013}}</ref> The AES had identical hardware to the MVS, allowing home users to play the games exactly as they were in the arcades;<ref>{{cite book|first=Andy|last=Slaven|title=Video Game Bible, 1985-2002|url=https://books.google.com/books?id=PnPRd6QwvbQC&pg=PA338|year=2002 |publisher=Trafford Publishing|isbn=978-1-55369-731-2|pages=338–}}</ref> however, cartridges are not inter-compatible due to different physical sizes, meaning that software releases differed for the two systems. 

The Neo Geo MVS was a success during the 1990s due to the cabinet's low cost, multiple cartridge slots, and compact size. Several successful video game series were released for the platform, such as ''[[Fatal Fury]]'', ''[[Art of Fighting]]'', ''[[Samurai Shodown]]'', ''[[World Heroes]]'', ''[[The King of Fighters]]'', ''[[Twinkle Star Sprites]]'' and ''[[Metal Slug]]''; game software production lasted until 2004,<ref>Hirohiko Niizumi, [http://www.gamespot.com/neo/action/samuraishodownvspecial/news.html?sid=6103366&om_act=convert&om_clk=newsfeatures&tag=newsfeatures;title;2], ''GameSpot'', July 23, 2004, Accessed June 8, 2008.</ref> making Neo Geo the longest-supported arcade system of all time.<ref>{{cite web |title=Longest support for an arcade system |url=http://www.guinnessworldrecords.com/world-records/longest-support-for-an-arcade-system |website=Guinness World Records}}</ref> The AES had a very niche market in Japan, though sales were very low in the U.S. due to its high price for both the hardware and software, but it has since gained a [[cult following]] and is now considered a [[collectable]].
