I unlinked my sysnand and emunand by using the system format method without the SD Card. After that, my sysnand friend code has changed but my emunand friend code was still the same as before, and my emunand has all my digital/eshop apps and games and such while my sysnand does not. My sysnand also does not have the save files of my retail cartridges anymore, only emunand classic does. It's basically like two different 3DS profiles on my one 3DS.
My question is how do I make it so my sysnand has all my retail cartridge saves (just so I have it there too), as well as my digital apps/games and the same friend code as my emunand?
