Nintendo’s Super Smash Bros. Ultimate patch notes for Version 13.0.5 are now live, and the update fixes one bug involving invalid data from sent and received online battles. For players who use replays, the practical issue is simple: the game now has a fresh patch, but some older replay files may need attention before installation.
Nintendo says replay compatibility may be affected for files from Ver. 9.0.0 to 13.0.4, while replays from Ver. 8.1.0 and earlier are not compatible. Players who want to preserve a replay can use Vault, then Replays, then Replay Data, then Convert to Video before updating.
Version 13.0.5 in Super Smash Bros. Ultimate
The update moved Super Smash Bros. Ultimate to Version 13.0.5, and Nintendo described it as a fix for a single bug tied to invalid data from online battles. The change is narrow, but it affects the part of the game where sent and received battle data is stored and handled.
That makes the patch more specific than a routine balance update. It targets one technical fault rather than gameplay tuning, so the most immediate effect is on the data path behind online battles rather than on matches themselves.
Replay Data and Convert to Video
Nintendo also flagged replays as the main practical issue for players. It warned that compatibility may be affected for replays from Ver. 9.0.0 to 13.0.4, and said replays from Ver. 8.1.0 and earlier are not compatible at all.
Players who want to keep a replay in a usable form before updating have one built-in option: open Vault, go to Replays, open Replay Data, then use Convert to Video. That step matters before installing Version 13.0.5, since the update changes the environment those files were created for.
June 2025 to 13.0.5
Version 13.0.4 was released in June 2025, making 13.0.5 the first new patch for the game in over a year. The gap gives the new update unusual weight for players who have relied on older online battle records and replay files during that stretch.
For those players, the immediate decision is whether any saved replay needs to be converted before updating. Nintendo has already given the path to do that, and Version 13.0.5 is the point at which older replay handling becomes the part to check first.
