    Have different points, if you like to play online and enjoy the homebrew stuff, you can mantain the sysnand with the last version on OFW online and the emuMMC with CFW always offline for homebrew without ban risk, this method require disable autoRCM and you need use jig and injector for enter on your emuMMC, the OFW boot like retail, just press your power button.

    Another point it's for patched units or people that don't want update their sysnand to run software exploits like pegaswitch or nereba, on this case the people mantain the sysnand on lower version possible and update their emuMMC to last version to play the last games, on this case their can't come online, if they come online with sysnand the firmware gona get updated, if they come online with the emuMMC have ban risk.

    And the last for advanced users, we can play with filesystem and test developments for the system without damage or brick the sysnand, we can mantain unlimited copies of the system to make experiments and backup/restore it the times that we want.

    Probably have another ways, but these three are the most used I guess.

    Thank you for your thorough points and reasons :) I'm going to keep this in mind and eventually migrate to using an emuNAND

    What if I used HBL/pegaswitch when it first got released? I have a NAND backup of when I did that (before I used CFW). Would that still be considered clean?

    emummc.ini for people looking to switch from sxos hidden emunand to emummc:

    Code:
    [emummc]
    emummc_enabled = 1
    emummc_sector = 0x2
    emummc_nintendo_path = Emutendo

    Thanks man you are a hero, i was going to use dd to extract my hidden emunand from sx os, then restore it as sysnand and then create the emuMMC with hekate but bruh it was going to take years lmao, you save me with this guide i just need to switch cfw and create a simple ini. No saves lost and no need to install all again :D:D:D. (hope they don't kill the compatibility :gun:)

    Do I get this right?
    I was always offline with my Switch (originally 3.0.0) and now I somehow lost my external HDD, where my NAND backup was located.
    That means I can clean up my NAND and go online without risking a ban?

    No. No backup, you are pretty much guaranteed a ban. Free of charge.

    Thats what I thought. Given the information on some posts in this thread, I assumed the opposite.

    Thanks for the reply :)

    But you can only try, my friend. Who knows, your tampering could go below their radar?
    That's what I'm gonna do, soon.
    Revert back to my original backup that I *believe is clean* and hope for the best.

    +1 for this method, that's pretty much the same thing I did to set up my emunand as well.
    I can't stress enough how much more convenient it is for those who have multiple partitions already on the SD card for things like switch linux.

    I agree, as I said before I refuse to use SX Tools for this, I prefer do it manually but on Windows are a fucking disaster do this (Actually I'm on Windows and the WSL didn't mount the USB properly) so I should wait to reboot and boot on Debian to do this.

    One question... Why fat32? isn't better exFat? On fat32 can't store files larger than 4GB, I didn't know if large games have files of more than 4GB. <-- Ignore this question

    Edit: Ok, I check the notes and the USER, SAFE and SYSTEM are fat32, so partition it's like sysnand.

    Thank you for the explanation, but should I format my sd card as exfat or FAT32?

    my switch has never been modified in anyway its form the first wave of consoles, I've been waiting for emummc to start using CFW. is there a guide out there for a beginner like me ?
    I'm just wanting to be able to edit Pokemon save files and botw files while in CFW then boot into OFW and be able to play online still and use the eshop.

    Dont do that way. Make a backup of your nand as rawnand.bin then use hacdiskmount to inject parts of the partitions to the nand backup.

    Double check your keys. The keys couldn't be wrong.
