I am using SX OS 2.8 BETA

I am trying to retrieve game saves from a 8.1.0 EmuNAND that won't boot anymore after accidentally modifying the USER partition with a homebrew app (added a file that doesn't belong there, didn't delete or modify anything else). The Nintendo and Switch logos show up, but quickly afterwards I get a crash error and I have to turn off the console.


So I figured I could use HacDiskMount by Rajkosto to read the EmuNAND on a Windows PC.

I joined the full.01.bin + full.02.bin + ... + full.07.bin into a single full.bin file. I can open the SYSTEM and SAFE successfully (with the respective BIS keys) except the USER partition. I get the FAILED message when I try to Test the BIS Key 3 pair with the USER partition. If I try to mount the USER partition anyway but it can't be read by the computer (unlike the SYSTEM and SAFE partitions, which can be mounted and read successfully using the respective BIS 1 and 2 Key pairs).

I'm using my console's dumped keys.

Is there any way I can repair or at least be able to mount my USER partition?


Any kind of help is appreciated.

Don't think emuNAND can be accessed from a computer.

It is possible to mount and read an emunand from a computer (I did it to retrieve saves as I was in the same case after upgrading from 7.x to 8.1). However, if the user partition is corrupted, I don’t know How you can fix it.
You can try to copy paste you emutendo folder if you have a backup previous « brick » of the emunand.

    Yea prob, n I own a Switch also, not just pirate the "good" games n play on a emulator. So I played lots of good games on actual Switch over the years, been a good console, esp for such dated hardware.

    Switch 2 will be your most powerful handheld (most likely) but Nintendo has always been a generation behind Sony/ Xbox, so doubt it will get the newest of games, n if it does, will be a watered down version, like Switch 1 got
  • K3Nv3 @ K3Nv3:
    Most powerful hardly series x specs will still crap on it
  • BigOnYa @ BigOnYa:
    Most powerful handheld I said. I imagine it won't last long tho, ROG or Steamdeck 2 will prob overpower it. I will prob buy a switch2 tho, gotta have that Mariokart 9.
  • K3Nv3 @ K3Nv3:
    I kinda doubt that also Asus will keep releasing or if Xbox doesn't come out with some handheld by then
  • K3Nv3 @ K3Nv3:

  • BigOnYa @ BigOnYa:
    I'm thinking of selling my current drum machine, piano keyboard, and few synthesizers, and buy a new $699 drum machine/ workstation. Downsize but upgrade. But like any device, ill never get the money I paid into it. Hard to let stuff go for half what you paid.
