Installing Minecraft

See Link here for more information

After you get done install Minecraft on your Steam deck you will then be able to log into your Minecraft Java Edition. I suggest setting updifferent version for the game if you have several different versions for example 1.16.2 and 18.1 and Maybe even 1.19.0+. I’ve found this to be the very easy to use and keep your from having to log into to your minecraft java edition. Once you have Micraft installed and ready to played. You really should go ahead create test world so you can verify that it is working properly. Once done you’ll want to process to the next step.

Zipping your saved worlds

This next step is important because you never know what could happen. You’ll want to hit “Win + R” and type in “%appdata%\.minecraft” while you are logged into your Windows device. This should bring your to C:\users\[loginID]\Appdata\.minecraft. Once there you will want to navigate to saves directory. You’ll find in most times it is there unless you have designated another location in the Minecraft Java launcher where to go. I’m going to assume you know where your save directory and we’ll talk about what you will need to do next.  I’d use something like 7zip or even Windows Zipping utility.  For the People who are absolutely beginners with this.   I recommend copying these to a USB and then copying them to the Steam Deck that way or you could use the microSD card if you have have a MicroSD card reader to move the zip files over.   Once you have zip the worlds you want to play on you Steam Deck.   You basically just want to zip the whole directory of the world name for example if you have a Test World on your Windows computer, it will probably be something like “Test World” folder.  Zip the whole directory up and copy it over.   Don’t change anything when it get’s zipped up.

If you have multiple worlds and have them set up with different version.   I’d suggest zipping them up and creating folders with the different version onto the USB or MicroSD card.  So when you create and import them into PolyMC you will know which versions you will need to create in Java PolyMC.

Importing world into PolyMC

Once you have them zip files copied over or at least installed on the MicroSD card and inserted into the the Steam Deck.    You are going to want to start PolyMC in Desktop mode if you are using this on the Steam Deck.   One you run it you’ll want to view the worlds:

Then once you do that, The next screen you will want to click Add (saved world).

Once you hit Add you will then want to go to the directory on the MicroSD card or USB drive or Where ever you moved the zip files. Once you find it and click OPEN. It should start to add it to the PolyMC World. If you created the right version you will not have to worry about it when you start the game. After Adding all the worlds you want to play with, you can then get out of Steam Deck Desktop mode and go back to the the Steam OS and play your game that you were playing on your PC. I haven’t tried moving these back to the PC or keeping them syncorized but at least you can play your favorite worlds on Steam Deck.

Like this little quick tutorial. Why not share it and tell people so more people can play Minecraft and or use your worlds you were using it on the PC. This will only work for the JAVA version of Minecraft. Bedrock will probably not work, I haven’t tried or thought about trying it for Steam Deck. Hope this helps. Have a Good Monday Morning.
