The Game Processor is a special software development kit by Nintendo/Intelligent Systems. The hardware was used by students at the HAL College of Technology & Design. The Game Processor was made because the Nintendo & Dentsu Game Seminar was relatively popular. Nintendo received more applicants than they could manage, which lead to more game design sessions at HAL College of Technology & Design.[1] The main software for it is Mario Factory, which allows the creation of Super Famicom compatible games.

Games are stored on a special cartridge known as the Game Processor RAM Cassette.

Satoshi Yamato, Satoshi Nishiumi, Toshiaki Suzuki, Toshiyuki Nakamura, Makoto Kimizuka take credit as inventors of the Game Processor.[2]

From January 1996, Nintendo and St.GIGA would distribute six Game Processor games in various HAL College Special editions of the Game Tora no Ouana (ゲーム虎の大穴スペシャル) Satellaview magazine series.

The concept of Mario Factory is similar to Nintendo's consumer software creation tools in video games, spanning from early games such as Family BASIC to later games such as Game Builder Garage.


The setup contains a 32-bit computer and Super Famicom hardware. Video output uses the "Super Impose" technology in which outputs are overlaid by each other, similar to Sega's 32X. The kit is plugged into a consumer TV with four controller ports, with compatibility for Super Famicom controllers, the SNES Mouse and a unique keyboard.
