The pack marks the longest gap between the original release of a Super Mario game and the release of its DLC, with the first wave releasing nearly five years after Mario Kart 8 Deluxe did. The pass was released through six waves, with each wave containing eight total courses (divided into two cups of four courses each). In addition to the courses, starting with Wave 4's release, the pass also features eight additional playable characters for the game, which also return from other Mario Kart games. The courses are based on their designs from Mario Kart Tour, but with significant visual improvements and new music arrangements. First announced during the February 2022 Nintendo Direct, the pack includes twelve additional cups, for a total of 48 additional courses (bringing the total number of courses in the game to 96), most of which are remastered versions of courses from other Mario Kart games, including Mario Kart Tour. The Mario Kart 8 Deluxe – Booster Course Pass, sometimes formatted as Mario Kart 8 Deluxe: Booster Course Pass on Nintendo's Oceanian website, is a DLC expansion pack for Mario Kart 8 Deluxe.
