Fourth generation of video game consoles
Nintendo executives were initially reluctant to design a new system, but as the market transitioned to the newer hardware, Nintendo saw the erosion of the commanding market share it had built up with the Nintendo Entertainment System. Nintendo's fourth-generation console, the Super Famicom, was released in Japan on November 21, 1990; Nintendo's initial shipment of 300,000 units sold out within hours. The machine reached North America as the Super Nintendo Entertainment System on August 23, 1991, and Europe and Australia in April 1992.
Super 8 (video game accessory)
The Super 8, also sold under the title Tri-star or Tristar, is an unlicensed video game peripheral released in 1995 for the Super Nintendo Entertainment System designed to allow the system to run games developed for the Nintendo Entertainment System. The Super 8 utilized an NES-on-a-chip integrated circuit to duplicate the functionality of the original NES hardware, and connected to the SNES's own cartridge slot.
