    EmuMMC is just a fancy term given to emuNAND in this case. Technically speaking they are basically the same thing.

    nice , do you use ofw when you play your online games (from sx menu you launch ofw?)


    yes it allows you to boot into ofw (i usually always updated my games this way and still haven't been banned after a year)

    EmuMMC = correct term (in the switch's case)
    Emunand = old school term(nds/Wii)

    That's all

    I don't get the whole deal with versions. So, as of right now, does emuMMC only work for low firmwares? Or does the firmware only determine how you boot into OFW/CFW?

    I still dont get why people think nsp is better than xci... Id rather jut go to a menu for a sec to load a game than have to install and uninstall something every time the nand/sd card is full.
    Surely XCI from usb hdd trumps nsp???

    Anyway on topic, its good that there are options for emunand now, personally i dont bother with either (Still unbanned) but i may in the future if the features of both CFWs are eventually combined. Atmos with xci from hdd and id move across without argument. Ive had my moneys worth out of my SX purchase so im happy either way.

    Waiting for Atmosphere 0.9.1 and new Hekate, then i'll migrate my emuNAND from SX-OS to Atmosphere.
    Still gotta figure out the fastest way to do that...

    Nice work.

    Been waiting for this one for quite a while.

    Will be using this.

    Also to quickly clarify my guess as to why it's emuMMC:
    • This is the same implementation that SX does for their emuMMC, except it's much saner.
    • This is not the method they want to permanently keep using, afaik the eventual intent is to switch (heh) over to using thermosphere, which is specifically making use of the EL2 mode of the Switch. This is not thermosphere. The reason they don't have thermosphere as of yet is because they ran into memory issues with making thermosphere. (there's only three memory pages of RAM for EL2).
    • Plus of course, the already stated technically better definition.
    Also, I heard that the file method is kinda broken in this release, so you'll have to use the partition method for now (which is better anyways.)

    What would be the difference to what we have now vs thermosphere (their eventual target)?

    User-end wise? Nothing.

    Background wise, it's a tad cleaner as it doesn't rely on patching fs.

    The current implementation are a file system redirection, the EL2 Mode are a virtualization through hypervisor and more optimized for ARM chipsets.

    Hey Guys

    Can i clarify

    Currently i have atmos on 7.01. Switched over from sx os a while ago. love it.

    With this emunand, what are the main advantages?

    Can i use emunand and play retail games online with a higher firmware? i remember on 3ds early days, you can keep sysnand on low, and then have an emunand on high firmware, and go online and keep emunand "clean". is this the case here?

    If you have unpatched unit the most recommended case for emunand are clean ofw on sysnand and cfw and homebrew stuff on the emummc.

    You need boot with hekate and apply patches to filesystem, so it can be detectable.

    You don't need to worry if you have unpatched RCM unit, you always gona can inject payloads to RCM, so stay on clean and last version of OFW on sysnand are safe, the other approach are for patched units that can run software exploits to enter on RCM mode, but as I said before, are risky because the "patched boot" are detectable.

    So the safest thing is still 100% clean second unit?

    damn it. I only have a tainted nand. :cry: I guess there is no real use for me then

    If you have an unclean NAND, either through piracy or tampering with stuff you shouldn't, but have kept it always offline and still have a clean NAND backup, do the following:
    • Backup your unclean NAND
    • Restore your clean NAND
    • Set up the unclean NAND for emuMMC
    Should be easy, but is probably handy.

    Thank you for your effort and work :)


    So what I think, feel free to correct me as I may not be up to date with switch scene:

    - I did a MMC backup on a clean switch 4.1, so I'll have to restore it. (I never updated sysMMC, so my fuses are not burned either)
    if you updated sysMMC you had to be sure you didn't burned fuse to be able to restore the MMC.

    - I'm using AutoRCM (I don't have a jig)

    - the purpose would be to be on clean updated sysMMC to access online games (for example), and use an exploit to boot emuMMC offline (for homebrew).

    - if I update to 7.0 and more, I think I've read that Hekate can't run "stock" anymore to boot OFW without burning fuses, so I'll have to update to >7.0 with burned fuses (not really a problem if I don't want to go back to lower firmware).
    but then, as there's no way to boot OFW from AutoRMC, I'll have to disable it to be able to boot OFW.

    - I could use (unreleased) deja vu 7.0< exploit to boot into CFW without jig, but if the purpose is to keep sysMMC updated (past 7.0) then I lose that feature and need a jig to boot into emuMMC.

    - if fuses are burned, emuMMC still work on mismatched CFW right?


    so, am I right ?
    - sysMMC : updated, burned fuses
    - no autoRCM anymore (cause hekate doesn't boot stock FW anymore). Or maybe I missed the fix from hekate?
    - jig required to boot into emuMMC

    Is there no "official payload booter" to replace hekate's stock option ? a way to boot the official one, like if there were no autoRCM ? it'll burn fuse, but then autoRCM will still be there and atmosphere will still work with incompatible fuse number.

    we could have a payload (like ArgonNX) to choose what to boot : stock, emu, linux, hekate. (and be careful not to boot other CFW using sysMMC, like hekate->cfw)

    Since my dumb self never backup a clean NAND, would formatting the Switch make it clean?

    no
    even less if you are already banned, formatting will not unban you.

    it'll only give you issues to restore your savegame and reinstall everything

    Nop.

    No, 7.x and up rely on sept. It doesn't burn extra fuses.
