    So since the switch has its NAND on a nice little removable PCB, I'm thinking it wouldn't be too hard to make a dual NAND solution,

    Is anyone working on this, I found replacement NAND boards on AliExpress.

    But a nice solderless solution is definately possible.

    I gues on earth.
    It is possible, but how would it work?
    1 nand updated and the other on like 1.0.0? There is no use for that.

    I'd prefer this over emuNAND to be honest, some kind of Xecuter DemoN type device.

    I'm curious if this would work as isn't nand supposed to be linked to console id

    Both nands can be "linked", but I can't see the use for it.
    You would need to bypass fuse checks in order to boot lower FW and I can't see any other use right now.

    it would be amazing to use CFW without getting banned on your main nand

    That's not how this works. That's why EmuNAND ban bans your entire console, not just the EmuNAND.

    Not if your second NAND or EmuNAND is OFFLINE.

    You can go offline with your main nand and get the same result.

    If you are offline you can't play online... The point is to keep the main NAND unbanned to play online.

    Oh. Ok. My main point is to not pay for online so...

    It is an alternative. :D

    There is no chance for that. Vocabulary here is important, removable does not mean swapable.

    Looking at https://www.ifixit.com/Teardown/Nintendo+Switch+Teardown/78263 it is not a trivial swap but not a huge effort and something you can do with just some screwdrivers and basic tools. Nothing consumable gets broken during that (thermal paste might be annoying but nothing too drastic like custom sticky pads).
    If you have a valid NAND dump from your Switch you can hopefully flash back to your replacement*, and could handle any fuse issues, then you could proceed to have a hacked version on one (presumably kept offline, presenting fake keys or at least disguising its keys) and a clean version on another (or two hacked ones if you wanted that for some reason).

    *while I expect the images to be locked to a given CPU I would be surprised to see them locked to a given NAND chip as well as that would gain little and probably frustrate repair efforts which is surely why they made it as modular as this in the first place.

    Was thinking of having a 'Clean' unmodified NAND for Online Use, and another 'Dirty' NAND for all your homebrew, etc.
    No, it wouldnt help you play backups online, but it 'should' help prevent a ban when you want to play legit games online.

    Im pretty sure some sort of custom PCB would be needed where the connector is duplicated and switched somehow,
    basically this

    I was thinking this the other day. I understand the nand pcb is console linked but could it be posible to bypass this using rcm?

    I wonder if cutting a hole in the back of the switch would make it easier :)

    Find a way to switch between both boards will be the hardest, and this may help you for information purposes

    Pinout for when pcb is connected to switch 4 wire method

    Pinout when disconnected from switch
    Your still need data and clk on other side. 6 wire method

    Should be doable with a FPGA.
