Super Nintendo Entertainment System

The Super Nintendo Entertainment System (Super NES or SNES) is a home video game console developed and marketed by Nintendo. It was released as the Super Famicom, in Japan on November 21, 1990, as the Super NES in North America on August 23, 1991, and internationally throughout 1992. It was Nintendo's second programmable home console, following the Nintendo Entertainment System (NES). A fourth-generation console, the Super NES primarily competed with the Sega Genesis in the console war, a fierce battle for market share in the United States and Europe.

Masayuki Uemura, a Nintendo engineer, designed the 16-bit Super NES in response to the introduction of the Genesis and NEC's TurboGrafx-16. The Super NES had advanced graphical and sound capabilities compared to its competitors, with features such as Mode 7 to simulate 3D perspective and eight-channel ADPCM audio. Its CPU was designed to accommodate ongoing technological innovations by allowing it to interface with enhancement chips, such as Super FX, integrated into game cartridges. Its controller built on the NES's with additional face buttons and two shoulder buttons. Nintendo released many accessories, including the Super Game Boy adapter to play Game Boy games and the Japan-exclusive Satellaview modem peripheral.
