Mario Circuit 1
From the Super Mario Wiki
Mario Circuit 1 is a race course that first appeared in Super Mario Kart, and as a retro track in Mario Kart: Super Circuit and Mario Kart DS, and is the first track to appear in the Mario Kart franchise.
Appearance in Super Mario Kart
Mario Circuit 1 is the first course of the Mushroom Cup in Super Mario Kart. The only hazard in this level are the pipes that appear near the second turn of the course. After the player passes the pipes, they will find the only set of item boxes in the course. There is also a shortcut a racer can take by driving through the dirt right after passing the item boxes. The player will need either a Mushroom or a Star to successfully implement the shortcut without slowing down. Taking the shortcut without an item does not take more time than following the course though.
Appearance in Mario Kart: Super Circuit
Mario Circuit 1 appeared in Mario Kart: Super Circuit, and is the first track in the Extra Mushroom Cup. It uses the background from Peach Circuit. The pipe hazards were removed from the track, but an item box can be found in the shortcut.
Appearance in Mario Kart DSShell Cup in Mario Kart DS. This level is relatively short as it has only three laps instead of five, and it usually takes the average player about 19 seconds to complete a lap. It is actually the shortest course in the game, however, this time the pipes are back on the second bend. Mission 1-8 (Perform 4 power-slide turbo boosts in 1 lap!) in this game takes place here. This course was available in Wi-Fi.
