Ultimate Version 13.0.5 Released – Patch Notes](https://www.nintendoreporters.com/storage/files/super-smash-bros-ultimate-version-1305-released-patch-notes.jpeg "Super Smash Bros. Ultimate Version 13.0.5 Released – Patch Notes")](https://www.nintendoreporters.com/storage/files/super-smash-bros-ultimate-version-1305-released-patch-notes.jpeg)**Summary:**

Super Smash Bros. Ultimate has received a small but important update: Version 13.0.5, released by Nintendo in early September 2026. This patch focuses on a single online-related fix that corrects unexpected behavior when invalid data is sent or received during online battles. While there are no fighter balance changes or new features, the update includes a clear note about replay compatibility – replays from several older versions may not work after installing the patch, so players who want to preserve them should convert replays to video first. For longtime players who care about ranked performance and saved replays, installing the update will ensure smoother online sessions and prevent odd disconnects that can affect Global Smash Power. Read on for a breakdown of what changed, why it matters, and how to handle replays before updating.

## [](#what-the-super-smash-bros-ultimate-13-0-5-update-changes)What the Super Smash Bros. Ultimate 13.0.5 Update Changes

This update is intentionally tiny in scope, and that’s part of why it matters. Version 13.0.5 addresses a specific online bug tied to invalid data being exchanged between players, which could cause unusual behavior or connection hiccups during matches. There are no new characters, stages, or balance adjustments in this release, so it won’t alter how the game feels in normal play. Instead, think of this as maintenance from Nintendo to keep the online experience working as intended. Because Super Smash Bros. Ultimate has a long history across multiple console generations, small compatibility issues can crop up as system firmware and online infrastructure evolve. Installing 13.0.5 will make sure your copy is on the same footing as other players who already updated, reducing the chance of match-breaking errors and preventing replay mismatches when you’re sharing or archiving battles.

### [](#fix-for-invalid-online-battle-data)Fix for Invalid Online Battle Data

The headline here is simple: Nintendo fixed behavior caused by invalid data sent or received during online battles. That can sound technical, but in practice it means matches that previously behaved oddly – sudden drops, frozen states, or results that didn’t reflect what happened – should be less likely to occur. For players who compete online frequently, even a single corrupted packet or malformed piece of data can ruin a match and affect Global Smash Power or rankings. While the patch note doesn’t list the exact technical conditions that caused the issue, the targeted nature of the fix suggests Nintendo patched a server-side handshake or client validation path so the game ignores or handles invalid inputs gracefully instead of producing broken behavior. If you’ve ever had a match end unexpectedly or seen strange results, this is the update that aims to stop that from happening again.

### [](#replay-compatibility-notes)Replay Compatibility Notes

One of the most useful pieces of info in the official announcement is the replay compatibility warning. Replays from versions 9.0.0 through 13.0.4 may not always be compatible after installing 13.0.5, and replays from version 8.1.0 and older are not compatible at all. That’s because replay files often include version-specific data structures or references to game assets that change across releases. If you have matches you want to keep, convert those replays into video files before updating – the in-game Vault provides a Convert to Video option under Replays. This isn’t an uncommon situation for long-lived games; as software evolves, binary replay formats are sometimes broken on purpose to avoid inconsistent playback. If you care about preserving epic wins, tight tournament sets, or speedrun attempts, take a couple of minutes to export them before you accept the update.

#### [](#how-to-save-your-replays-before-updating)How to Save Your Replays Before Updating

Saving replays to video is straightforward and only takes a few steps, but it’s worth doing before any update that warns about compatibility. From the Vault go to Replays, then choose Replay Data and select Convert to Video. Pick a few of your best matches and export them while your console still uses the pre-update replay format. If you rely on replays for analysis, coaching, or YouTube uploads, exporting now prevents losing footage you can’t recover later. Make sure you have enough free space on your system or microSD card before converting: video files are larger than replay files and you may want several quality copies. After conversion you can safely install the update knowing your highlights are preserved as shareable videos that will remain viewable regardless of future changes to the game’s replay format.

## [](#why-this-small-patch-matters)Why This Small Patch Matters

Small patches like 13.0.5 often fly under the radar because they don’t add flashy content, but they’re crucial stability work that keeps the game healthy long term. Super Smash Bros. Ultimate has a passionate competitive and casual community, and even minor bugs can have outsized effects when thousands of matches happen each day. Fixing invalid data handling reduces the chance of unfair match outcomes, lost progress, or corrupted replay files. It also signals that Nintendo is still paying attention to maintenance for this title – a reassuring sign if you’re worried about long-term online reliability. Even if you only play casually, a single disrupted match can sour the experience, so applying the patch is sensible housekeeping that keeps your online sessions reliable and predictable.

### [](#impact-on-competitive-play-and-gsp)Impact on Competitive Play and GSP

Competitive players and anyone tracking Global Smash Power should take a moment to consider the practical effects. A match ruined by invalid data can lead to an unjust loss or disconnect that hurts your GSP and ranking metrics. By tightening how the game handles malformed inputs, 13.0.5 reduces the chance that a technical fault, rather than player skill, decides the outcome. This matters during ladder climbs, online tournaments, and when you’re trying to replicate setups for training. While the patch doesn’t change fighter frames or hitboxes, it improves the playing field by reducing unpredictability. If you compete or grind for rank, update before your next session so you aren’t surprised by behavior that the new version already prevents.

#### [](#compatibility-across-switch-and-switch-2)Compatibility Across Switch and Switch 2

With Nintendo’s evolving hardware lineup, compatibility between Switch and Switch 2 versions of games and system firmware is an ongoing topic. The 13.0.5 patch notes point out potential local play incompatibility with versions older than 13.0.4, so you and your friends should match versions before you play locally. If you or a friend has moved to a Switch 2 and its system firmware, it’s still a good idea to confirm everyone updated the game. For broader context about Switch 2 and how some games are receiving updates to support new hardware, check NintendoReporters’ Switch 2 coverage and the main Nintendo News hub for related stories. Keeping consoles and game software aligned avoids awkward matchmaking problems and ensures your local and online sessions run smoothly together.

##### [](#how-to-update-and-check-your-version)How to Update and Check Your Version

Updating is simple: from the HOME Menu highlight the Super Smash Bros. Ultimate icon, press the + or – button and select Software Update, then choose Via the Internet. After updating, check the version number at the top-right of the title screen to confirm it reads Ver. 13.0.5. If automatic updates are enabled your console may already have downloaded and installed the patch while it was in sleep mode, but it’s still worth verifying before jumping into ranked matches. If you encounter problems downloading the update, make sure your internet connection is stable and you have enough storage space in internal memory or on your microSD card. For step-by-step troubleshooting, Nintendo’s support pages can walk you through common update errors and steps to fix them.

##### [](#conclusion)Conclusion

This is a small but practical update that improves online stability by fixing how the game handles invalid battle data, and it carries important replay compatibility warnings. Anyone who plays online or values saved replays should install 13.0.5 and export videos of any replays they want to keep. It’s a reminder that maintenance patches, even when minimal, play a big role in keeping long-running games healthy and enjoyable. Keep an eye on official support notes and community reports should more details appear, and enjoy smoother matches with the latest version installed.
