What is the fastest way to check my Mario Kart 8 Deluxe version?
You do not need to launch the game or start a race. The HOME Menu shows the installed software version in the game’s details panel.
- Press the Nintendo Switch HOME button to return to the HOME Menu.
- Move the selection to the Mario Kart 8 Deluxe icon. Do not press A to open it.
- Press the controller’s + or − button.
- Look beneath the software title in the details screen. The displayed value, such as Ver. 4.0.1, is the version installed on that console.
Nintendo’s Americas instructions describe this directly: “The current version number will display under the software title.” This check is useful when you want to verify a console before joining friends, troubleshoot an online feature, or confirm that an update actually completed.

The HOME Menu check is different from checking Nintendo’s update-history page. The console tells you what is installed; Nintendo’s regional support page tells you what release is currently listed for that region. Compare the two values rather than assuming that an older-looking date means the installation failed.
See Nintendo’s official Mario Kart 8 Deluxe update instructions for the same menu path and version-check method.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsHow do I update Mario Kart 8 Deluxe manually?
Use the HOME Menu’s software-update command when the version shown on your Switch is behind Nintendo’s current regional listing. The console needs an internet connection to retrieve the update.
- Return to the HOME Menu and highlight Mario Kart 8 Deluxe.
- Press + or − to open the software options.
- Select Software Update.
- Choose Via the Internet.
- Allow the Switch to download and install the available update. Keep the console connected while the process runs and follow any on-screen prompts.
The wording may look slightly different if the software is already current. In that case, the system can report that you are using the latest version instead of offering a new download. That result is not an error: it means the console’s installed version matches the update data available through Nintendo’s service at that time.
Nintendo also explains the general process in its guide to updating software on Nintendo Switch. A game update is separate from a system update, so selecting this command targets Mario Kart 8 Deluxe rather than changing the Switch operating system.
How do I know the update installed?
Use two checks: read the version again from the HOME Menu, then open the game and look at its title screen. Nintendo UK specifically recommends launching the software and confirming that the newest version number appears there.

- Return to the HOME Menu and highlight Mario Kart 8 Deluxe.
- Press + or − and read the version below the title.
- Launch the game.
- On the title screen, verify that the same current version number is displayed.
For the November 2026 release, you should see Ver. 4.0.1 if that is the version listed for your region. The HOME Menu is the quickest confirmation; the title screen is a second confirmation that the game itself recognizes the installed release.
If the number did not change, do not infer that the update is missing solely from a notification disappearing. Recheck the HOME Menu value and compare it with Nintendo’s current update-history page. A console can also already be current if the regional support page lists the same number that you see.
What is the current Mario Kart 8 Deluxe version?
Nintendo’s regional pages list Ver. 4.0.1 as the current version as listed on November 12, 2026. Nintendo of America dates the release to October 13, 2026, while Nintendo UK dates it to October 14, 2026. Those dates are not a contradiction; use the page serving your country or Nintendo Account region.

| Source region | Version listed | Release date shown | What to compare on your Switch |
|---|---|---|---|
| Nintendo of America | Ver. 4.0.1 | October 13, 2026 | The number below the game title in HOME Menu details |
| Nintendo UK | Ver. 4.0.1 | October 14, 2026 | The number below the game title and on the title screen |
Nintendo can publish a newer revision after this article’s date. If you are checking later, treat 4.0.1 as the version identified at the time of publication, not as a permanent guarantee. The safest process is to open the relevant Nintendo UK update history or the applicable regional Nintendo support page and compare the exact version string.
What changed in Ver. 4.0.1?
Nintendo’s published notes identify four issue fixes. They are Nintendo’s own release notes, not independent performance measurements.
- Corrected an issue affecting obstacle or Item Box counts during Online Play and Wireless Play on Nintendo Switch 2.
- Corrected an issue involving the selection of a registered system user for two-player Online Play and Wireless Play.
- Corrected missing Star Bits on Wii Rainbow Road when playing on Nintendo Switch 2.
- Corrected an issue that could cause the game to close unexpectedly under certain conditions.
The notes do not describe a new game mode, a general graphics overhaul, or a change to every course. If you are deciding whether a console needs the update, the version check is still the authoritative answer: install the available release even if you have not encountered one of the listed issues.
Can Mario Kart 8 Deluxe update automatically?
Yes. Nintendo says automatic downloading and installation can occur when the Switch is connected to the internet and Software Auto-Updates is enabled. Automatic updating is convenient, but a manual check is better when you need to confirm a specific version before playing with someone else.
To check the setting, open System Settings from the HOME Menu, scroll to System, and review the Software Auto-Update setting. The exact menu wording can vary slightly by system-language configuration, but the relevant setting is the one that allows software updates to download automatically. A console that has been offline, powered down without an internet connection, or configured with automatic updates disabled may not have received the latest game data.
Recommended Free Tools
Automatic updating does not remove the manual route. Highlight the game, press + or −, and choose Software Update > Via the Internet whenever you want an immediate check. The HOME Menu version number remains the way to verify the result.
Why does Mario Kart 8 Deluxe say an update is required for online play?
Nintendo says the game’s internet features require the update to be applied, and all players must use the same software version to play together. If one console is on an older release, that mismatch can prevent the players from joining the same online or wireless session.
Ask every player to perform the HOME Menu check rather than relying on the date they last played. Each person should highlight Mario Kart 8 Deluxe, press + or −, and compare the displayed version with Nintendo’s current listing. If a number is older, that console should use Software Update > Via the Internet before trying the multiplayer session again.
Nintendo’s support page states: “All players must be using the same version of the software to play together.” Matching versions does not mean every player must own the same edition of the console; it means the installed game software must match.

What should I do if the update will not download because of storage?
If Nintendo Switch reports that there is not enough space, check the available storage in the console’s system memory and, if present, the installed microSD card. Nintendo identifies either location as a place where update data may be stored.
- Open System Settings from the HOME Menu.
- Select Data Management.
- Review the available space in system memory and on the microSD card, if one is installed.
- Remove or archive software you no longer need, or manage other data to make room.
- Return to the game icon and run Software Update > Via the Internet again.
A microSD card is not required for ordinary version checking, and adding one does not guarantee that every update problem will be resolved. Nintendo’s guidance does not endorse a particular card brand, model, capacity, or speed for this procedure. Treat external storage as a conditional solution only when the console identifies insufficient available space.
If the storage warning continues after you free space, note the exact message shown by the Switch and consult Nintendo’s support documentation for that error. Do not repeatedly delete unrelated game data without first checking whether you need its save data or downloadable content.
Does updating remove my Mario Kart 8 Deluxe save data?
Nintendo says save data remains available after downloading the update. The update changes the software files; it is not described as a command to erase progress.

One free scan finds every outdated or missing driver and matches the right update for your exact hardware.Free scan · exact hardware matchEven so, use the normal Data Management menus carefully. Updating through the game’s Software Update option is different from deleting the software, deleting save data, or deleting update data. Those actions appear in separate management areas and have different consequences.
Players using a physical game card should pay particular attention to the distinction. Nintendo’s DLC troubleshooting guidance says that if a physical-copy player deletes software update data, the software must be updated again. That instruction concerns removed update files; it does not say that installing an ordinary update deletes save data.
Is the Booster Course Pass required to install a game update?
No. Installing a Mario Kart 8 Deluxe software update and accessing downloadable content are separate matters. The update route is the HOME Menu command Software Update > Via the Internet; membership verification for the Booster Course Pass is handled when the relevant content is launched.
Nintendo’s page about being unable to access Mario Kart 8 Deluxe DLC says an internet connection is required at launch to verify a Nintendo Switch Online + Expansion Pack membership for Booster Course Pass access. That requirement should not be interpreted as a requirement to hold the membership merely to install the base game’s software update.
If you use a physical game card and delete its software update data, Nintendo says you must download the update again before playing with the current files. Keep the update question and the DLC-access question separate when troubleshooting.

What if the version number still looks wrong?
Work through the checks in order instead of repeating the same download command.
- Read the number again: return to the HOME Menu, highlight the game, press + or −, and record the exact version string.
- Check the correct regional page: compare that number with Nintendo’s current update-history listing for your region. Release dates can differ by one day between regional pages.
- Confirm the internet route: run Software Update > Via the Internet while the console is connected.
- Check storage: if the console reports insufficient space, review system memory and microSD capacity through System Settings > Data Management.
- Confirm in the game: launch Mario Kart 8 Deluxe and look for the newest number on the title screen.
- Compare with other players: for online or wireless play, have every participant verify the installed version independently.
If the HOME Menu and title screen show the same number, the installation has been recognized by both software entry points. If Nintendo’s regional page has moved to a newer release after the date covered here, follow that newer page rather than treating 4.0.1 as the final version forever.
What is the difference between checking the HOME Menu and checking the title screen?
The HOME Menu check is available without launching the game and is therefore the quickest way to inspect the installed version. The title-screen check happens after launch and provides a second confirmation inside the game.
Neither screen replaces Nintendo’s update-history page. The console screens tell you what is installed locally; Nintendo’s page tells you which release Nintendo currently documents. Using all three references resolves most apparent discrepancies, especially when a regional release date or a new update has just been published.
What do I need before starting the update?
Have the Switch, the Mario Kart 8 Deluxe software installed or the game card inserted, an internet connection, and enough available storage for the update data. You do not need to open the game first, and you do not need a microSD card simply to inspect the version number.
If the console is offline, you can still read the installed version from the HOME Menu, but you cannot use Via the Internet to retrieve a newer release. Connect the Switch before attempting the manual download. If the console has automatic updates enabled, Nintendo says it can download and install software updates while connected, but manual verification remains the clearest option when timing matters.

FAQ
Can I check the installed version while the Switch is offline?
Yes. The HOME Menu reads the version already installed on the console and does not require an internet connection for that local check. Internet access is needed only when you choose Via the Internet to look for and download a newer release.

Why do Nintendo’s Americas and UK pages show different release dates?
Nintendo publishes regional support information, and the pages can assign different local release dates to the same version. For Ver. 4.0.1, the Americas page shows October 13, 2026, while the UK page shows October 14, 2026; the version identifier itself is the same.
Do I need Nintendo Switch Online to download a Mario Kart 8 Deluxe update?
The cited update instructions require an internet connection, but they do not state that a Nintendo Switch Online membership is required to install the software update. Membership verification is discussed separately for accessing Booster Course Pass content.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Can two consoles play together if one uses a game card and the other uses a digital copy?
Nintendo’s stated multiplayer condition is that all players use the same software version. The source guidance does not make the game-card-versus-digital format the deciding factor, so compare the version numbers on both consoles rather than the purchase format.
What should I record when contacting Nintendo about a failed update?
Record the exact version shown under the game title, the version listed on your regional Nintendo page, any storage warning, and whether the title screen shows the same number. Those details distinguish a version mismatch from an interrupted download or a storage-related failure.
