Hacking Booting into another Switch's EmuNAND

[Levente]

Long time ago I created an EmuNAND with SXOS from my first Switch and everything was working ok.
Now I accidentally updated this Switch to the latest official firmware, so SXOS won't boot anymore.
I have a second Switch on lower firmware also with SXOS.

My question is, if it would be possible to access the EmuNAND created from the first switch on the second switch somehow? Now when I try to boot into the EmuNAND of the first switch on the second one with the correct license.dat file, it only boots to a black screen.

Tried with SXOS 3.1.0
Any ideas are welcome. Thank you.

You can't boot into another Emunand, but you can Backup your Savegames with JKSV or Checkpoint on
Switch #1 and Restore them on Switch #2.

How can I do that on Switch #1? It is on the latest firmware and SXOS won't boot.

Thanks for you help!

I managed to boot into EmuNAND with atmosphere!

The solution is creating an emuMMC folder on the root of you SD card with an emummc.ini file which contains:

[emummc]
enabled=1
sector=0x2
path=Emutendo
id=0x0000
nintendo_path=Emutendo

Then you can boot into hekate, the hekate_ipl.ini file should look like below and after clicking Launch you should choose the third option Atmosphere Emu, which will take you to EmuNAND:

{--- Nintendo Stock ---}
[OFW (SYSNAND)]
emummc_force_disable=1
fss0=atmosphere/fusee-secondary.bin
stock=1
icon=bootloader/res/ofw.bmp
{}

[Atmosphere (CFW)]
payload=bootloader/payloads/fusee-primary.bin
emummc_force_disable=1
{}

{------Atmosphere Emu------}
[Atmosphere (emuMMC)]
payload=bootloader/payloads/fusee-primary.bin
{}

Also remember to include the sigpatches for atmosphere.

wait you booted into another switchs emunand?

No sorry, that is the EmuNAND on Switch #1, which I can access with atmosphere now.

For Atmosphere 1.0.0:

{--- Nintendo Stock ---}
[OFW (SYSNAND)]
emummc_force_disable=1
fss0=atmosphere/package3
stock=1
{}

[Atmosphere (CFW)]
payload=bootloader/payloads/package3
emummc_force_disable=1
{}

{------Atmosphere Emu------}
[Atmosphere (emuMMC)]
payload=bootloader/payloads/fusee.bin
{}

You can download fusee.bin from atmosphere's github page.
