Overview
- Nintendo released Version 13.0.5 for Super Smash Bros. Ultimate on Sept. 1, 2026 to address a bug that occurred when invalid data was sent or received during online battles.
- The company’s support notes warn that replays from versions 9.0.0–13.0.4 may have compatibility issues and that replays from 8.1.0 and earlier are not compatible with the new patch.
- Nintendo instructs users who want to keep replay files to convert them to video using Vault → Replays → Replay Data → Convert to Video before installing the update.
- This is a small, targeted maintenance update rather than a content release and does not add gameplay features or balance changes.
- The patch was released as part of a series of routine Nintendo updates that week and should improve online stability for players, though anyone with important replay files should act before updating.
