Wave 1 of the Mario Kart 8 Deluxe Booster Course Pass was released on March 18, 2022, introducing eight remastered tracks across two new cups: the Golden Dash Cup and the Lucky Cat Cup.

The "extra quality" movement emerged to counter this. Modders quickly extracted higher-resolution textures from the Tour versions of these tracks, upscaled environment maps using AI (like ESRGAN), and repackaged them into modded NSPs or LayeredFS patches.
