You can download version 12.1.0 now.
Nintendo has rolled a new firmware update for its flagship console. This time bringing it all the way to version 12.1.0. This update will allow you to delete games to create space for more games, as well as some stability improvements.
Here are the full patch notes:
- If there is not enough space remaining on the system memory (internal storage) or microSD card when downloading game software update data, you can now delete old data for that software, enabling you to download the new data.
- When deleting the old data, you won’t be able to play the game until the new data has finished downloading.
- General system stability improvements have been made to enhance the user’s experience.
