Ahead of the arrival of Mario Kart World next month, Mario Kart 8 Deluxe has received a new update bumping it up to Version 3.0.4. This likely isn't the final update for the game, but it is probably the last one we'll be getting before the new entry speeds onto the Switch 2 in June.
So, what exactly does this latest update include? It's multiple "general" fixes revolving some various issues. Here are the full patch notes, courtesy of the official Nintendo support page:
Mario Kart 8 Deluxe Ver. 3.0.4 (Released May 13, 2025)
General
- Fixed issue where, when playing “3DS Music Park” during Time Trials and the player opened and closed the pause menu over and over, the timing of the “notes” jumping lost sync with the background music and ghost data that was registered would start not playing correctly.
- The timing of the “notes” jumping still loses sync with the background music when opening and closing the menu even after applying updated data, but they will jump at correct timing when the ghost data plays.
- Ghost data for “3DS Music Park” that was created in Ver.3.0.3. or earlier cannot be uploaded.
- Ghost data that has this problem occur may be deleted without prior notice from “Online Ghosts.”
- Fixed issue where coins thrown by spectators disappear before they fall onto the course in “N64 Rainbow Road.”
