SD Preparation

We will now place the required files for the Atmosphere custom firmware and some additional homebrew files on the SD card.

Atmosphere has its own bootloader, called fusee (primary). For the purposes of this guide we will be using Hekate instead, so that we can back up the system's NAND (internal storage) and take advantage of other advanced features in the future.



Your SD card will need to be formatted as either FAT32 or exFAT. FAT32 is recommended as it is more stable and will work out of the box with the Switch's operating system, but has a file size limit of 4GB. If you plan on using exFAT, you will need to install the exFAT update for your Switch, which is downloaded when you insert an exFAT formatted SD card in to your Switch. Note that this will update your console and requires an internet connection. I recommend FAT32 because I read about too many data loss from the CFW users.

File name extensions

If you use Windows, you should enable file name extensions before continuing. See this link for a guide on how to do this.

Restoring your existing Nintendo folder

If you were already using your microSD card as a storage device for your games and backed it up before partitioning your microSD card, it is now safe to restore it. Place it back on the root of your microSD card.

if you want same games on emuMMC, you need to copy the contents of the Nintendo folder from the root of the sd card to the emummc/RAW1/Nintendo folder.
