Super Smash Bros.
Ultimate Version 13.0.5 arrives for Nintendo Switch on September 1, 2026, marking a small but notable maintenance update for Nintendo's long-running platform fighter.
Super Smash Bros.
Ultimate was developed by Bandai Namco Studios and Sora Ltd., directed by Masahiro Sakurai, and originally released for Nintendo Switch on December 7, 2018.
The game remains one of the Switch's best-selling and most actively maintained competitive titles.
What this update does
Nintendo published Version 13.0.5 as a targeted stability patch.
According to Nintendo's support notes, the patch corrects behavior that occurs when invalid data is sent or received during online battles.
In practical terms, this fix aims to reduce errors or crashes tied to malformed or unexpected network data while playing online.
Replay compatibility and how to preserve clips
Nintendo also warns players about replay compatibility after installing the update.
Replays saved under versions 9.0.0 through 13.0.4 may experience compatibility issues when opened after updating to 13.0.5.
Replays created in Version 8.1.0 and earlier are not compatible with current software.
To preserve important footage, Nintendo advises converting replays into standard video files before applying the patch.
The conversion path in-game is: Vault → Replays → Replay Data → Convert to Video.
Other Nintendo updates this week
Alongside the Super Smash Bros.
Ultimate patch, Nintendo rolled out fresh updates for other Switch titles this week, including Mario Kart 8 Deluxe and Pikmin 3 Deluxe as free Switch 2 versions.
These updates reflect Nintendo's ongoing support for high-profile first-party releases across the Switch lifecycle.
Why this matters
While Version 13.0.5 is not a content update or balance patch, stability fixes for online play are important for both casual and competitive communities that rely on consistent multiplayer sessions.
The replay compatibility notice is a practical consideration for content creators and competitive players who keep archives of matches.
How to get the update
Players can download Version 13.0.5 via the Nintendo Switch system UI or by launching Super Smash Bros.
Ultimate while connected to the internet.
As always, convert or export any replays you wish to keep before installing the update to avoid potential loss of replay data.
