Guide for Setting Up EmuMMC for Your Hacked Nintendo Switch with Windows



  1. Make sure everything on your SD Card is backed up on to your computer.

  2. Open DiskGenius.

  3. Click on your SD Card in the left menu. It is very important to select the correct device from this menu as this will be destructive.

  7. Make sure the partition type is set to "Primary Partition", and the file system type is "FAT32". To get the size of the partition you will want to take the total size available in MB and subtract it by 29856 MB to get the size of your first partition. (Ex 30436 - 29856 = 579) Give your partition a label, and then click "Ok". This will be your SD Card partition that holds your atmosphere, bootloader, Nintendo, etc... folders.

  8. In the center right click in the empty space and click on "Create New Parition(N)" again.

  9. Make sure the partition type is set to "Primary Partition", and the file system type is "Linux swap". The default size should be 29856 MB, and you should not be able to give this parition a label, simply click "Ok" when everything looks good. This will be the partition for your emuMMC.

  11. Once it finishes Windows will mount your SD Card, you may get a dialog prompt to format a drive. You will always want to hit "Cancel" on this. This is because Windows can not read your emuMMC partition.

  21. Congratulations you are done. You can go into "System Settings", scroll down to "System", and you should see an "E" at the end of your "Current version:" indicating you are in your emuMMC.
