Hacking How can I create and use correctly an Emummc with Atmosphere and keep sysnand online play ?

[Xyphoseos]

Hello, I want to create an emunand and keep my online play on sysnand. I know a lot of thing but I want to be sure.

I saw a lot of guide that aren't identical, what is the best guide to follow ?
Nintendo folder, it will be the same for Sys and Emu or they will be different ?
It is better to install auto_rcm or not ? (protect fuse burn isn't necessary, I just want to know what is the best)
I know that I must keep emunand offline, but there are others things that I must avoid ?

If I have to know any other thing, please let me know.

I usualy do not use Emunand, but this is for a friend.

Edit: this switch is totally clean, never hacked.

By default, emuMMC and sysMMC use different folders. You can have them use the same one, use completely different ones, or clone the one for sysMMC so both can use their own independently.

AutoRCM is a personal preference for entering RCM.

Also avoid using CFW on whichever partition you will go online which doesn't have to be sysMMC. A misconception with the scene is that you cannot go online with emuMMC but that is far from the truth. emuMMC is the only users with patched consoles can go online so emuMMC is designed to be used online.
