The Hardware

One board. Two housings. The identical arcade hardware argument - and the family it spawned.

The Core System

AES vs MVS - One Board, Two Housings

The Neo Geo’s fundamental selling point was a genuine engineering decision: SNK designed a single hardware specification for both the MVS (Multi Video System) arcade board and the AES (Advanced Entertainment System) home console. Both units use the same CPU, sound chip, video hardware, and ROM access architecture.

The MVS came in several configurations - 1-slot, 2-slot, 4-slot, and 6-slot cabinets - allowing arcade operators to run multiple games in a single cabinet by swapping cartridges. The AES packaged the same board in a home console form factor with two joystick ports and an AV output. When a new SNK title appeared on MVS, home players could purchase the AES version and play the identical experience.

Neo Geo CD

Released in September 1994 in Japan and 1995 internationally, the Neo Geo CD was SNK’s attempt to address the AES’s most significant barrier: cartridge pricing. By moving to CD-ROM storage, SNK could offer Neo Geo titles at significantly lower prices - typically $50–$70 versus $100–$200 for AES cartridges.

The tradeoff was load times. The original Neo Geo CD used a single-speed CD-ROM drive (150 KB/s), resulting in load times of 30–90 seconds between stages - a significant interruption to arcade-derived titles designed for seamless play. SNK released the Neo Geo CDZ in 1995 (Japan-only) with a double-speed drive that reduced load times to a more acceptable 15–40 seconds.

Neo Geo Pocket & Pocket Color

The Neo Geo Pocket launched in October 1998 in Japan - a handheld system with a monochrome display. It was replaced in March 1999 by the Neo Geo Pocket Color, a colour-capable model that launched globally. The Pocket Color competed directly with the Nintendo Game Boy Color, releasing in the same year.

Despite a strong library - including SNK vs. Capcom: Match of the Millennium (widely regarded as the finest fighting game on a handheld until Street Fighter IV 3DS), King of Fighters R-2, and Sonic the Hedgehog Pocket Adventure - the Neo Geo Pocket Color was discontinued in 2000 following SNK’s financial difficulties. Production of cartridges continued by third parties through 2001.

Neo Geo AES Duo-R

The Neo Geo AES Duo-R was a revised version of the AES console released in Japan in 1993. It featured a redesigned case with a top-loading cartridge slot (replacing the front-loading design of the original AES) and used the same hardware internally. The revision was primarily cosmetic and ergonomic, with no changes to the game board or compatibility.

The Duo-R is noticeably more compact than the original AES and was the version of the home hardware most commonly found in Japanese households during the platform’s commercial peak. Internationally, the original AES design remained in production.
