Nintendo has issued a small maintenance patch for Super Smash Bros.
Ultimate on Nintendo Switch, bringing the game to Version 13.0.5.
The update, published on September 1, 2026, targets online stability by correcting behavior that occurred when invalid data was sent or received during online battles.
Super Smash Bros.
Ultimate, developed by Sora Ltd. in collaboration with Bandai Namco Studios and published by Nintendo, has received its first update since June 2025.
The 13.0.5 patch is narrowly focused: Nintendo's official support notes state the fix addresses occurrences tied to invalid online battle data, improving the integrity of online matches for Switch users.
Nintendo also warns players about replay compatibility following the update.
Replays saved from versions 9.0.0 through 13.0.4 may encounter compatibility issues after installing Version 13.0.5, while replays from Version 8.1.0 and earlier are not compatible.
To preserve older recordings, Nintendo advises converting replays into standard video files prior to updating by navigating Vault → Replays → Replay Data → Convert to Video in-game.
This patch arrives alongside other Nintendo Switch updates released the same week, including new builds for Mario Kart 8 Deluxe and Pikmin 3 Deluxe.
Those releases are part of Nintendo's ongoing post-launch support for its Switch library.
For players and community members tracking the live build, Version 13.0.5 is a targeted rollback of a specific online edge case rather than a broader balance or content update.
Nintendo's support page is the definitive source for the patch notes and replay conversion instructions.
What players should do
- Install Version 13.0.5 to receive the online data fix and maintain match stability.
- If you want to keep older replays, convert them to video before updating: Vault → Replays → Replay Data → Convert to Video.
As with previous maintenance updates for Smash Ultimate on Nintendo Switch, this release underscores Nintendo and the development team's ongoing commitment to online service stability and archive preservation.
