However, for players using files of Mario Kart 8 Deluxe + DLC (via custom firmware or emulation like Ryujinx/Yuzu), Wave 1 runs flawlessly. The file size for the update (v2.0.0) was roughly 1.2GB, adding the new courses, music, and character assets without breaking existing mods.

If you are sourcing an Mario Kart 8 Deluxe [0100152000022800] [v196608] (DLC) [NSP] , ensure you have the correct title ID and update patch. Wave 1 requires the base game to be updated to at least version 2.0.0.
