The Nintendo VS. System (Japanese: 任天堂VS.システム Hepburn: Nintendō Buiesu Shisutemu), officially sold simply as the VS. System (VS.システム Buiesu Shisutemu), is a coin-operated video game platform sold to arcades from 1984 to 1990. Designed for two-player competitive play using the VS. UniSystem or VS. DualSystem and with arcade system boards based on the Nintendo Entertainment System, many of these stand-up or sit-down arcade machines have two screens and controllers joined at an angle. Cutting costs compared to higher powered arcade hardware, games were ported from existing home video games for the Family Computer and Nintendo Entertainment System.
The VS. System was designed primarily as a kit to retrofit Donkey Kong, Donkey Kong Jr., Popeye, and Mario Bros. machines; as such, they require the same special monitor that these coin-ops use. These monitors use inverse voltage levels for their video signals as compared to most arcade monitors. Commercially available converters allow one to use any standard open frame monitor with the game.
Almost all the games on the VS. System run on identical hardware powered by a Ricoh 2A03 Central processing unit, the same found in the Nintendo Entertainment System but with the exception of special PPUs, or video chips designed for this circuit boards (RP2C04-0001, RP2C04-0002, RP2C04-0003, RP2C04-0004, RC2C03B, RC2C03C, RC2C05-01, RC2C05-03, RC2C05-04, and RP2C03B). Each chip contains a different palette that arrange the colors in different configurations chosen apparently at random. Most boards can be switched to a new game simply by swapping the program ROMs, though the appropriate PPU must also be used; if not, the game will appear with incorrect colors. Several of the later VS. games employ further measures of protection by using special PPUs which swap pairs of I/O registers or return special data from normally unimplemented regions of memory. Attempts to run these games in other VS. Systems will result in the game failing to even start.
Some dedicated VS. double cabinets were produced which look like two games butted together at an angle. A single motherboard powers both games on those models.
The VS. Table, a steel sit-down cabinet for the VS. DualSystem, allow play for up to four players simultaneously. This cabinet uses the same motherboard as the double cabinet.
Because the VS. System has the same CPU that is in the Nintendo Entertainment System, VS. System games can be ported to the NES with modifications to the console including extra memory banks and additional DIP switches.
Some games are different from their Famicom/NES versions. For example, VS. Super Mario Bros. is considerably more difficult than Super Mario Bros.; some of the levels were reused in Super Mario Bros. 2 for the Family Computer Disk System. The graphics are also different from their Famicom/NES counterparts; for example, VS. Duck Hunt has more details and animation sequences than its console counterpart.
