1. remove the old SD card from switchSorry if I have misunderstood.
So to copy contents from my old SD card to the new SD card with the hidden emunand, how specifically do I do that? I can't see my hidden emunand when I plug the SD card into my computer.
And then I just rename the Nintendo folder to Emutendo, right? And then everything will be the same as before on the emunand as it was on the sysnand?
2. copy boot.dat and license.dat to the new SD card, put it in to the switch
3. create emunand
4. copy Nintendo folder from the old SD card to the new SD card (yes you won't see the hidden emunand but it doesn't matter. just copy it to the SD card partition you see in your PC)
5. rename Nintendo folder to Emutendo
