This is not a so simple questions...I need some more information...

    The parameter in emummc.ini are not random values, they need to be setted correctly, so if you don't have a emuMMC/RAW1 folder or this folder is empty, this emummc.ini sample is not useful.

    The SX emunand was on hidden partition or on files?
    The Emunand boots correctly with SX?

    Check if in /emuMMC/EF00/ there are BOOT0, BOOT1 and from 00 to 07 files
    If yes then you can easily move the /emuMMC/EF00/Nintendo folder to the root and rename it as Emutendo and then copy all the emuMMC/EF00 files in /sxos/Emunand and rename the BOOT0 in boot0.bin, BOOT1 in boot1.bin and file 00 in full.00.bin, the file 01 in full.01.bin and so on
    Now SXOS should boot correctly

    If the original sx emunand was in hidden partition, than it should be still there. Move the /emuMMC/EF00/Nintendo folder to the root and rename it as Emutendo
    Try to check if it boots on sxos.

    The only way to have an emunand that boots with both SX and Atmosphere is the hidden partition emunand.
    You can use Emutool to copy a Emunand on File to an Hidden partition, but you need to backup the SD on PC, because the conversion procedure erase the SD.
    You need to backup the /emuMMC/EF00/ and /emuMMC/EF00/Nintendo
    1) You can start with SXOS menu and start a new Emunand on hidden partition (now it erase the SD card)
    2) As soon as boot0 and boot1 are done click cancel to interrupt the process.
    3) Switch all off, put the sd card on the PC and start Emutool as Administrator.
    4) In Emutool select Hekate on File as source and browse where you copied the /emuMMC/EF00/ files (boot0, boot1, 00, 01, ecc.) and select SXOS Partition as target and choose the correct SD card.
    5)Now start the copy, at the end copy /emuMMC/EF00/Nintendo folder to the SD root and rename it as Emutendo.
    Now it should boot with sxos
    6)create a folder emuMMC in the root and create this emummc.ini file in it

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

    If you plan to do a fresh new emunand start from sxos menu, create a hidden partition emunand and follow only the preceeding step 6) to enable it for Atmosphere

    Hope it helps, sorry for my English.
