Yoshi's Island was developed by Nintendo EAD and published by Nintendo for the Super Nintendo Entertainment System (SNES). According to Miyamoto, who served as a producer, Yoshi's Island was
in development for four years, which let the team add "lots of magic tricks". The game cartridge used an extra microchip to support the game's rotation, scaling and other sprite-changing special effects. Yoshi's Island was designed to use the Super FX chip, but when Nintendo stopped supporting the chip, the game became the first to use Argonaut Games's
Super FX2 microchip. The chip powered scenes including a drawbridge falling into the foreground, rotation effects like rolling and enlarged rather than reanimated enemies, and a psychedelic effect in a level when Yoshi touches a floating fungus.
