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 Controller
The Super Controller is an accessory for the Nintendo Entertainment System video game console. It was released by Bandai and was a plastic clip-on device that was supposed to allow the player to have a better NES playing experience. The original NES controller could be inserted inside by snapping open the back. The Super Controller still allowed the player to use the original A, B, Start, and Select buttons on the NES controller; the only difference was an arcade stick-like knob that fit over the D-pad of the original NES controller.
