The VS. System is a collection of coin-operated VS. UniSystem or VS. DualSystem arcade systems that first appeared in 1984. As their name implies, the video games are designed for competitive play. The VS. UniSystem is like a conventional upright arcade cabinet with two sets of controls and a single screen. The VS. UniSystem can either come as a dedicated gray cabinet or be a conversion from Donkey Kong, Donkey Kong Jr., or Popeye cabinets. It is not possible to convert the dedicated wide-body Mario Bros. cabinets or the Punch-Out!! cabinets. In Japan, there are conversion kits for cocktail cabinets.^[2] The VS. DualSystem comes with two screens and four sets of controls. Although these cabinets were designed for up to four simultaneous players, only the launch title, VS. Tennis, takes advantage of this capability. The upright type looks like two machines conjoined at an angle while the sit-down type is red and lets players face each other. The latter was renamed VS. Table.^[3] The VS. Table is the earliest VS. System form factor and is the most common one found in Japan.^[4] It was unveiled in January 1984 and became available the following month.^[1]

The VS. System was designed in response to the video game crash of 1983, which saw arcade machine operators facing declining revenue while taking big risks in each new purchase. Nintendo responded by creating the Nintendo-Pak conversion kits for Mario Bros. in addition to selling the dedicated wide-body cabinets.^[5] Donkey Kong 3 was available only as a Nintendo-Pak, which spared operators from having to buy the cabinet.^[6] The VS. System goes further by having a cabinet and PCB that allowed operators to easily swap the PPUs and ROMs for each new release with a VS.-Pak. The cost savings led to the purchase of around a hundred thousand machines and conversion kits in the US alone by 1986.^[7] Its success spurred the development of the Nintendo PlayChoice-10.

The games are mostly ports of Nintendo Entertainment System home console games, although many have notable changes in their graphics, gameplay, and difficulty. One exception is VS. Wrecking Crew, which came out a year before the NES version and is very different from the latter. There are also regional differences between the Japanese and overseas releases. Nintendo's final first party VS. System titles were each released in Japan in 1985^[4] and in North America in 1990. The Micro VS. System line of Game & Watch games released in 1984 was named after its arcade counterpart.
