of course it works, why wouldn't it? not sure why this old ass thread is being bumped though why not just use DayBreak lol

Traditionally people would use SX OS bootloader to create the emunand. I have a dualboot Emunand but my sysnand is on 11.0.0.

yeah atmos 16.0.0 emuMMC

just downgrade an 'Atmos emuNAND' and re-name file scheme to SX's there's nothing proprietary to them, my sys is still on 9.1.0

 

[Hayato213]

yeah atmos 16.0.0 emuMMC

Anyway you can try this

### Skip steps 1,2,3 if you already have Atmosphere partition based ###
1. Hekate: set partitions. Allocate 29 Gb for the EmuMMC.
Optional (but you have to decide at this stage): allocate partitions for Android and Linux e.g. 32GB each, you'll be able to come back later and go Flash Android or Flash Linux (just remember how much space you allocated because it doesn't display when you come back to the partition menu).
2. Hekate: Generate an EmuMMC (partition)
3. Install the Atmosphere files on the SD Card
4. Hekate: Generate an EmuMMC (File based because they can't be two partition based EmuMMCs on the same SD card) - at this point Hekate will select the File based partition as the default EmuMMC location because it is the last created
5. Boot atmosphere, make sure you are on the EmuMMC, "E" at the end of the Firmware version, downgrade to FW 11.0.0 via Album>Daybreak
6. Hekate: Mount the SD card on your computer via Tools.
7. Open NxNandManager (https://github.com/eliboa/NxNandManager/releases) on your PC, open your File based EmuMMC, resize User to 9760Mb (Total: 12.5 Gb), export as File based EmuMMC (I tried to Save as SXOS EmuNAND but it fails at 99% - hence step 7 below instead)
8. Open Kenny's Emutool (https://gbatemp.net/threads/emutool...er-sd-switch-emu-type-on-sxos-and-more.550756). Convert your reduced File based EmuMMC (in EmuMMC\SD00 on your Sd card) to File based EMUNAND for SXOS (choose to root of your SD file as Target path, it will export to sd:/sxos/emunand). Delete the File based EmuMMC on your Sd card.
9. Drop SXOS boot.dat and license.dat at the root of your SD card -you should have from your previous SXOS installation or the Free SXOS script for file based EmuNAND by Reacher17 Le Fantastique (https://gbatemp.net/threads/hack-sxos.582831/page-63)
10. Hekate: let's fix the side effect of step 4. Redefine the partition based EmuMMC as the active one via EmuMMC tools > Migrate EmuMMC > Fix Raw
11. Edit hekate_ipl.ini adding these lines so that you only need to boot to Hekate then choose your CFW moving forward
[SX OS]
payload=bootloader/payloads/sxos.bin
12. Press "+" while launching for the first time to see the SXOS option and make sure the Emunand is active (i.e. not booting SXOS on Sysnand) which should be the case because SXOS will detect the existing File based Emunand if it was created correctly.
