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. This course 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 in Mario Kart 7, this is the only GBA classic course in the base Mario Kart 8 content. It now features a starting banner with the classic Mario Kart logo in red, 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. This section is balanced on what appear to be giant car jacks (which are named “Ultra Arm”, a reference to the ), which can be seen rising to lift the section into its position in the course's preview, with many large Brick Blocks and Empty Blocks visible in the pit where the U-turn was originally. There are also oil slicks near the end of the track that cause players who collide with them to spin out, alongside some traffic cones that are knocked away when players collide with them. The detour near the finish line also contains an added Item Box in addition to the Dash Panel. Compared to the original, the road is also slightly banked through the curves.

The music has been modified to a slightly lower pitch and plays in A#/B♭ major on the first two laps and then in B major on the final lap, as opposed to C major in the original. Overall, the arrangement appears to be based on that of the Mario Kart: Super Circuit prototype.

When the player crosses the finish line to start another lap, Lakitu is shown on the right side of the player, holding the lap count signs (when holding the start signal, he is also shown on the right side of the player).

Shortcut(s)

 * To the right of the second line of Item Boxes, there is a Glide Ramp hidden by some trees that can be accessed by using a Mushroom or Super Star.

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.

Mario Kart 8 Original Soundtrack liner notes
"This circuit has been dramatically reworked, so we reflected that in the music by rearranging it and making generous use of a horn section."

Trivia

 * This is the only Mario Circuit to not feature any Warp Pipes.
 * The course was originally known as Big Tree Circuit and was in the Mushroom Cup in an early prototype of Mario Kart: Super Circuit, and also had a different musical arrangement not present in the final build. The side route right before the finish line was also absent.
