Nintendo Vs. System
The Nintendo Vs. System is a collection of coin-operated VS. UniSystem or VS. DualSystem arcade systems that arose in the 1980s. As their name implies, the video games are designed for two-player competitive play. They can be either stand-up or sit-down arcade machines, and usually have two screens and controls joined at an angle. The games are all ports of Nintendo Entertainment System home console games, although many have notable changes in their graphics, gameplay and difficulty.
