Q: What is Firmware? Why does my Switch always prompt for updates?
A: Firmware is the system software of the Switch, equivalent to the operating system of the console. Each update prompt is usually to fix vulnerabilities, improve stability, or prepare for upcoming games. If you skip several updates, the system will accumulate many security patches and new features, and the next time you boot up, it will keep popping up to update—it's not that you're being careless; Nintendo has just piled up several rounds of fixes.

Q: Can I still play games normally if I don't update the firmware?
A: Most physical game cartridges can run normally, especially older games. However, if you want to go online, use the eShop, upload screenshots, or play certain new titles that require the latest system, you'll be stuck. For example, shortly after The Legend of Zelda: Tears of the Kingdom was released, Nintendo pushed a firmware update to improve stability. Machines that weren't updated could still enter the game, but occasional frame drops and loading stalls occurred. So if you mainly play offline old games, you can hold out for a while without updating. But as long as you go online or want to play major titles from that year (refer to our site's Switch game recommendations and Nintendo game recommendations), updating firmware is essentially unavoidable.

Q: Will updating firmware clear my save data?
A: Normal updates won't, but in very rare cases (such as a power outage, removing the game card, or losing internet connection during the update), there's a slim chance the console could become bricked or save data could be corrupted. A safe practice is: ensure battery life is above 50% before updating, keep it plugged in, and don't remove the dock or shut down halfway through. If you play two-player Switch games where saves are often shared between two accounts, remember to check if cloud saves are synced after the update. If you bought Nintendo Switch Game Vouchers or digital versions, it's best to restart once after updating before launching a game.

Q: Which games cannot be played due to a firmware version being too low?
A: In recent years, major titles have become increasingly dependent on new firmware. For instance, when Xenoblade Chronicles 3 and Pokémon Scarlet/Violet were released, they required upgrading to at least a certain firmware version to run. Some indie game recommendations for niche titles are more lenient on firmware requirements, but if you play large ported titles like Hogwarts Legacy or Hi-Fi Rush, an outdated machine version will directly throw an error prompting you to update. Additionally, popular games on the game chart that consistently rank high, such as Splatoon 3 and Animal Crossing: New Horizons, will have online features restricted if the firmware isn't updated—you can't even access the Salmon Run mode.

Q: How do I determine whether to update this time?
A: Several practical criteria to consider:
1. Does the game you want to play soon show a "need to update system" prompt? (You can check the minimum system version in the game encyclopedia.)
2. Are online functions normal? If you frequently get disconnected or can't find matches, the update may have fixed network modules.
3. Read the update log—if it says "fix vulnerabilities" or "improve stability," you can update. If it only says "improve system smoothness," it's not necessary to update; some users report worse battery life after updating (though unconfirmed officially, there are indeed many such feedbacks).
4. If you've tinkered with custom themes or mods, absolutely do not update—firmware updates will patch these vulnerabilities.

Q: To sum up, should firmware be updated frequently?
A: You don't need to chase the latest, but don't skip too many. Updating two or three times a year can cover the needs of most new releases. If you have a large library of digital games and a family membership shared account (like many players in the Xingba community), keeping firmware reasonably updated actually reduces future compatibility issues. Physical cartridge players can take it easy, but don't wait until you want to play a new title and get forced to update—by then you'll have to download for hours and restart the game, which is a real downer.
