The Nintendo VS. System is an arcade system that was developed and produced by Nintendo. It is based on most of the same hardware as the Family Computer (Famicom), later released as the Nintendo Entertainment System (NES). As Nintendo was planning to release the NES in North America, they were aware of the video game crash of 1983 and its effects on the home console market. However by March 1984 the arcade industry recovered enough for a plan to introduce NES titles there, with the VS. System later being a presentation to players who did not yet own the console. It became the first version of the Famicom hardware to debut in North America.
