GBA Mario Circuit

Mario Circuit from Mario Kart: Super Circuit is part of the Flower Cup as the first race course. 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 Boost Pad located there. It's also the first track titled "Mario Circuit" in the Mario Kart series, as Super Mario Kart had more than one Mario Circuit, while Mario Kart 64 had Mario Raceway.

Mario Kart 8
This Mario Circuit appears in Mario Kart 8 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 vanilla version of the game (excluding Cheese Land and Ribbon Road which are in DLC cups). 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 gliding pad 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.

Trivia

 * This is the only Mario Circuit not to feature any Warp Pipes.
 * In the Mario Kart 8 version, the U-turn is seen being lifted up into position by Ultra Hands during the preview. In the pit where the U-turn originally was are many Brick Blocks and Used Blocks.
