Quickest ( I think ) way to convert Atmosphere style microsd+emunand to SXOS style microsd+emunand
* Goodies:
- EmuTool: https://github.com/TheyKilledKenny/Emutool/releases
- Minitool Partition Wizard ( free ): https://cdn2.minitool.com/?p=pw&e=pw-free
* Optional goodies ( if you have emunand 11.0.1, to hybridize it for SX OS, steps 0 and 7 ):
- lockpick_RCM payload to obtain your prod.keys: https://github.com/shchmue/Lockpick_RCM/releases
- NxNandManager: https://github.com/eliboa/NxNandManager/releases ( I used the x64 version )
- BCPKG2 package: < removed link, please go to sthetix's twitter account and use the link there >
* The steps I do to convert an atmosphere style microsd to an SXOS style microsd are:
optional 0) If your emunand is 11.0.1, you need to hybridize it with replacement bcpkg2 and for that you need your prod.keys file:
- use lockpick_RCM.bin and dump keys from emunand. These are stored in sdcard:/switch/prod.keys. You can grab this and save it elsewhere, but you can use it from that location directly too.
1) Use Emutool to save the atmosphere hidden partition to an atmosphere file.
2) Use Minitool Partition Wizard ( free ) to:
- delete the hidden emunand partition and apply changes.
- move the FAT32 ( if you use exFAT you are out of luck and you will need to do the long way, copy contents, format as FAT32 and copy back, or maybe use another tool that can convert or move esFAT ) partition to the very end of the physical space. Take care to leave 29.22 GB ( or a bit more, it won't hurt ) of free space on the beginning of the physical space. And apply changes. This took a bit more than half an hour for a 400GB sdcard that was almost full, way less than doing it the long way by copying contents and restoring them and all that.
3) Use Emutool to restore the atmosphere file to the microsd as SXOS hidden partition.
4) Move the Nintendo folder found in sdcard:/emuMMC/RAW1/ to sdcard:/, that is, you have sdcard:/emuMMC/RAW1/Nintendo and you must end up having sdcard:/Nintendo
5) Rename sdcard:/Nintendo to sdcard:/Emutendo
6) Use Emutool, select sxos hidden partition emu as source and click on Activate emu button that appears below. This is needed for SXOS to detect and use the hidden emunand partition. ( Thank you @TheyKilledKenny ! ).
optional 7) if your emunand is 11.0.1, you need to hybridize it with replacement bcpkg2 by replacing the 4 partitions on the sxos style emunand:
- start NxNandManager and go to Options>Configure keyset and click Import keys from file and select the prod.keys file obtained in step 0 ( from sdcard:/switch/ or from wherever you saved it ). Make sure the key slots are filled in and clicked Save
- go to File>Open drive and select the microsd drive.
- click on BCPKG2-1-Normal-Main in Partitions pane and click on backup file icon to back it up
- click on BCPKG2-2-Normal-Sub in Partitions pane and clicked on backup file icon to back it up
- click on BCPKG2-3-SafeMode-Main in Partitions pane and clicked on backup file icon to back it up
- click on BCPKG2-4-SafeMode-Sub in Partitions pane and clicked on backup file icon to back it up
- click again on BCPKG2-1-Normal-Main in Partitions pane and click on restore file icon and select the equally named file from the package sthetix linked on his twitter and confirm
- click again on BCPKG2-2-Normal-Sub in Partitions pane and click on restore file icon and select the equally named file from the package sthetix linked on his twitter and confirm
- click again on BCPKG2-3-SafeMode-Main in Partitions pane and click on restore file icon and select the equally named file from the package sthetix linked on his twitter and confirm
- click again on BCPKG2-4-SafeMode-Sub in Partitions pane and click on restore file icon and select the equally named file from the package sthetix linked on his twitter and confirm
EDIT: Needless to remind you that making this SXOS style microsd and emunand compatible with atmosphere is quite easy, look it up here on GBATemp or elsewhere. Also, I'd recommend ending up with such a combo, so you can then easily use both OSes almost without changing the microsd layout.
Good luck
