Switch:Minecraft world management

Required Reading

The Nintendo Switch release of Minecraft Bedrock edition does not permit importing worlds from external sources in-game. However, there is a trick to import your world to Minecraft that involves using a save manager and creating a blank world to replace with your downloaded world.

This guide works on emuMMC as well as sysCFW, but be warned: there is always a ban risk when messing with sysMMC. While people have reported successes with using this guide in sysMMC without getting banned, this can change.

What You Need

• A copy of Minecraft
• Checkpoint (the Checkpoint.nro file) or JKSV (the JKSV.nro file) in your /switch folder

Instructions

Section I - Creating a dummy world and backing up your save

1. Boot to Atmosphère on your Switch
2. Launch Minecraft
3. Once it is loaded, create a new world with a name distinct from your other worlds, if you have any. This is used to identify the world save later in the guide.
4. After it has been created, exit the world, then close Minecraft
5. Launch the Homebrew Menu using either title takeover (recommended) or the album applet and load either Checkpoint or JKSV
6. Select your user if needed, select Minecraft, back up the save (any name works), then exit

Section II - Copying the world files

1. Reboot to Hekate
2. Go to Tools -> USB Tools -> SD Card and connect your Switch to your PC
3. These next steps will differ depending on if you used Checkpoint or JKSV:
   • Checkpoint users: Navigate to /switch/Checkpoint/saves/0x0100D71004694000 Minecraft/ and enter the folder for your dumped save
   • JKSV users: Navigate to /JKSV/Minecraft/, copy the zip archive for your dumped save to your PC, extract it and enter the created folder
4. Navigate to games/com.mojang/minecraftWorlds/
5. For each subfolder:
   1. Inside the subfolder, open levelname.txt and see if the contents of the file matches your world name you set in section I step 3
   2. If it is the correct name, delete the contents of this subfolder (not the subfolder itself) and replace it with the contents of your downloaded world (file and folder structure should match)
   3. If it isn't the correct name, move on to the next subfolder
6. For JKSV users only: Go back to the path where your copied zip archive is, delete the zip archive, compress to .zip/send to zip archive, copy this newly created zip archive and place it in /JKSV/Minecraft on your Switch, replacing the existing archive
7. Eject your Switch and disconnect it from your PC

Section III - Importing the modified save

1. From Hekate, boot into Atmosphère
2. Launch the Homebrew Menu using either title takeover (recommended) or the album applet and load either Checkpoint or JKSV.
3. Select your user if needed, select Minecraft, select your save, restore it, then exit

You should now have your custom world imported into Minecraft!
