Which studio developed Mario Kart: Super Circuit?

Intelligent Systems developed Mario Kart: Super Circuit.

Released for the Game Boy Advance in 2001, Super Circuit was the third main Mario Kart game and the first designed for a handheld console. It was the only Mario Kart title developed by Intelligent Systems, a Nintendo-affiliated studio also known for series such as Fire Emblem and Advance Wars.

Super Circuit built on ideas from Super Mario Kart and Mario Kart 64. Its presentation echoed the SNES original, including a bright overhead style and Mode 7-inspired visual effects, while the Game Boy Advance hardware allowed a much larger course selection. The game included 40 tracks: 20 new circuits and 20 unlockable tracks from Super Mario Kart.

Players could race in Grand Prix, Time Trial, and Quick Run modes, while multiplayer supported up to four systems through the Game Link Cable. Some players confuse Intelligent Systems with Nintendo EAD, which developed several console entries, or with later outside collaborators. For Super Circuit itself, Intelligent Systems is the canonical developer.
