Nintendo has released a new software update for Super Mario 3D World + Bowser’s Fury, bringing the game to version 1.2.1 on the Nintendo Switch 2. The patch addresses system behaviour issues, while a much bigger update has also gone live for Mario Kart World, introducing gameplay tweaks, bug fixes, and quality-of-life improvements.
Super Mario 3D World + Bowser’s Fury gets Switch 2 compatibility patch
The latest patch for Super Mario 3D World + Bowser’s Fury focuses on ensuring smoother gameplay on the Switch 2. While the update is small in scope, Nintendo confirms that it resolves system-level behaviour problems specific to the new hardware.
This update is compatible with local play versions 1.2.0 and 1.1.0. However, it won’t work with version 1.0.0, so players should double-check their game versions before starting multiplayer sessions.
Mario Kart World version 1.2.0 brings major changes
In contrast to the subtle Mario update, Mario Kart World has received a massive overhaul with version 1.2.0. Nintendo has tweaked everything from item distribution to CPU difficulty and race settings.
Among the standout features:
- New item rule options like “Mushrooms only” and “No COM” in single and multiplayer VS Race.
- Weaker AI in all modes except Battle.
- Players can now spectate specific racers in Online Play and view replays after downloading ghost data.
- Camera settings are now retained until the game is closed.
Nintendo has also increased the appearance rate of lap-type courses in VS and wireless races, a move that reverses previous changes which had frustrated fans.
Dozens of bugs squashed in Mario Kart World
The update also addresses a long list of bugs, ranging from minor glitches to gameplay-affecting issues. Fixes include:
- Incorrect item changes mid-race.
- Characters falling out of bounds or getting stuck on terrain.
- Crashes caused by Bullet Bill usage and Smart Steering bugs.
- Graphical glitches and UI inconsistencies across multiple tracks.
These changes should result in a smoother and more balanced racing experience for Switch 2 players.
