The tutorial is more like

Setup EmuMMC, From SX to Atmosphere and keep using the both worlds.

If the moderator by any chance to come here, could you please change the title? Thanks.


YOU HAVE BEEN WARNED

There is always at least a risk to get you banned or unlikely to brick your Switch.
YOU'RE AT YOUR OWN RISK
I TAKE NO RESPONSIBILITY FOR ANY DAMAGES OR BAN.

You can use your current setup of SX's Emunand (hidden partition on the SD) to boot Atmosphere's Emummc using this tutorial. This will be considered as dual emunand booting. Take advantage of the both worlds.

CLEAN UP SYSNAND
> Skip this step if you're using SX's Emunand and being online on Sysnand.
> If you didn't have any previous clean nand backup before
You have no choice here to clean up a dirty nand without a clean nand backup but to believe in this method
> Stop here if you don't want to hurt yourself or even me
​

Spoiler: PRESS

Skip this step if your Switch is a brand new one or never ever been hacked.

CREATE EMUNAND AS HIDDEN PARTITION ON SD
> If you're SX Users and have been using their Emunand as hidden partition, just skip this step, go to COPY FILES
> Take advantage of SX Emunand creator (without valid license needed)
> Your SD will be formatted, backup your savedata and other data are needed.

Spoiler: PRESS

Before creating emunand > Ensure you did delete all WIFI connections and turned on Airplane / Flight mode

Go to SX website > download their latest boot.dat > copy to the root of your SD
Download payload.bin for activating payload via your chosen tools

SX OS Bootloader Menu
> Options
> EmuNAND
> Create EmuNAND
> Hidden Partition on microSD

You will get "successfully done"

COPY FILES

Spoiler: PRESS

Go to Atmosphere GitHub and download the latest release 0.9.0 and extract all files/ folders to the root of your SD

Create > emummc folder on the root of the SD

Create > emummc.ini file inside of emummc folder

Copy and paste this to emummc.ini

[emummc]
emummc_enabled = 1
emummc_sector = 0x2
emummc_nintendo_path = Emutendo <<< delete this line if you're not SX Users or don't want to keep using SX as your primary CFW

I got banned from ReSwitched discord because of Emutendo word. I'd like to help someone out but ended up in unexpected way. But it's okay.

Hope this will help out.
Enjoy!

games installed with emunand on Sysnand I get error. already installed on sd card do not give errors

 

[pcwizard7]

the best way to have atmos emunand and be able to still get into my existing sxos emunand?

i m guessing both are using the same nintendo folder which u can't do as they a link to the nand that created it

Do you mean if I install a NSP in emunand, if I go back to sysnand the NSP will still be installed?

hOw TeH tUrnTabLeS ,

NOW ATMOSPHERE IS STEALING FROM SXOS OMGWTFBBQ

 

[pcwizard7]

if the sysnand thinks its already installed it sounds like its looking in the same place

EDIT. the title information is store in the nand but game data is on sd card

If you're using SX, installed files will be stored in Emutendo folder on the root of your SD. Atmosphere uses Nintendo_000 folder stored in emummc folder on by default. You can change the installing folder by editing emummc\emummc.ini

emummc_nintendo_path = Emutendo

In this case, Emutendo folder will be used as installed folder for both SX and Atmosphere. You can change to any name like emummc_nintendo_path = YourNand/MyEmutendo (YourNand is the folder on the root of your SD, MyEmutendo folder inside of YourNand folder)

Cheers.

You don't have to use that part. It's for SX Emunand as files on SD to transfer to hidden partition.

How Do I dual boot emunand of ams using SX OS emunand with visible files on sd card?

 

[delta nite]

I'm having a black screen after the second Atmosphere logo. I also never tried booting into Atmos before. Is this something to do with the emummc or something else?
I'm at 8.0.1 and using fusee-primary, is that related?

It's hard to tell, if your sysnand does boot, its replication as emunand will be worked.
fusee-primary.bin is to boot Atmosphere.

Yesterday I also had the same problem booting from Atmosphere's payload. So, should I boot emunand from SX payload? If I remember correctly there was an option to boot either from cfw or OFW.

You can't use SX Bootloader to chain boot fusee_primary.bin. Currently, the best way to boot Atmosphere is using payloader on PC or smartphone.
You can use SX > Reboot to payload homebrew (the one in atmosphere package) to reboot to Atmosphere and use Reboot to SX to reboot to SX vice versa.

Got it.

Just one question, when I got my switch it came with FW 4.0.1, now that FW doesn't support exFat and my SD card has exFAT format. Could that be the reason why I'm getting the black screen when booting atmosphere?

Yea, that's why. Try Fat32 instead of then update firmware on emummc to the latest one with exfat using choinx

So I'm going to risk sounding like a total noob, but what is the point of emuNAND? Is it to protect you from being banned online?
It doesn't sound like it's a guaranteed work around from what people are saying on here.

For my case, I am currently on FW 8.0.1 with AutoRCM and 5 burnt efuses. So, once Nereba will be ported for FW 4.X, I will be able to downgrade to get back a console which can boot "without assistance" (AutoRCM could be a huge problem for battery if the console crashes and you don't have a PC/dongle) and I will be able to boot to the EmuMMC without the "paperclip" procedure.

But I agree with you about online, nothing is really safe to avoid ban (including probably XCI, Nintendo could easily detect it in future FW).

Yeah I'm running CFW ReiNX on v7.0.1 and I have saved eFuses since v3 or v4 (don't remember) since I always use ChoiDejourNX to do my FW upgrading.
I have a dongle with the payload on it so I don't have much to worry about, but I was wondering if AutoRCM was going to make it so I could play online. I guess not, although there aren't really any games I care to play online (Was excited for Ultimate, but input lag and bad netcode killed any hype I had for it).
