GBA Mario Circuit

Mario Circuit is the first race course of the Flower Cup in Mario Kart: Super Circuit. This Mario Circuit is a rather plain stage and short in length, with few obstacles and Item Boxes to deal against rivals. It contains winding paths, however, such as a hairpin bend, or a curl path found before the home stretch. Next to the checked line there is a detour where racers can get a speed boost by running onto a Dash Panel located there. It is also the first track titled "Mario Circuit" in the English versions of the Mario Kart series, as Super Mario Kart had more than one Mario Circuit, while Mario Kart 64 had Mario Raceway in English. This track shares its music with Peach Circuit and Luigi Circuit.

Mario Kart 8 / Mario Kart 8 Deluxe
This Mario Circuit reappears in Mario Kart 8 and Mario Kart 8 Deluxe as the second course in the Shell Cup. Much like Bowser Castle 1 in Mario Kart 7, this is the only GBA retro track in the base Mario Kart 8 content. It now features a starting banner with black-and-white tires around the posts, various stacked tires and advertisements, and huts both filled with Toad and Yoshi spectators and oil cans. The large U turn near the beginning of the track is slanted and separated from the track to act as an anti gravity section. There are also oil slicks that the players must avoid, similar to the original Super Mario Kart Mario Circuit tracks. Unlike other courses from Super Mario Kart and Mario Kart: Super Circuit that have appeared as retro courses in more recent games, the road is also slightly banked through the curves. There is a Glide Ramp that can be used as a shortcut. The music has been modified to a slightly lower pitch and plays in B♭ Major on the first two laps and then in B Major on the final lap, as opposed to C Major in the original.

Staff ghost
The staff ghost for this track is Baby Mario on the Yoshi Bike, and Baby Luigi on the Sport Bike in Mario Kart 8 Deluxe's 200cc Time Trial.

Trivia

 * In the Mario Kart 8 version, the U-turn is seen being lifted up into position by s during the preview. In the pit where the U-turn originally was are many Brick Blocks and Used Blocks.
 * The music in the Mario Kart 8 version is based on the Mario Kart: Super Circuit prototype.
