About EmuMMC/EmuNAND

The emuMMC (or EmuNAND) refers to the copy of Switch’s internal storage, which is saved on SD card. The copy includes all the content that is required for running Switch, including firmware, data storage, system settings and games that are installed to internal storage.

Therefore, you can have multiple separate installations of Switch’s operating system. Besides, any changes made to an emuMMC like WiFi settings, installed games will not affect other emuMMCs or sysMMC.

Read here, you may raise a question “how to set up EmuMMC/EmuNAND” like most people. Since the whole EmuMMC/EmuNAND setup operation is complicated, the post will divide it into several phases. Please follow me to walk through the article now. 

Phase 1: Check Your Serial Number

The first phase of setting up EmuMMC/EmuNAND is to check whether you have the access to set it. Go to a website called Is My Switch Patched and fill in your serial number and the prefix. Then you will know if your console is patched or not.

If it says that your Switch is unpatched then you are good to go to follow this guide and you should be able to get the MU MMC setup correctly.

Therefore, it is recommended that you pick up a Micro SD card of at least 64 gigabytes because a 32 gigabytes card won’t really work for the setting up EmuMMC/EmuNAND operation.
