How to use LayeredFS for Backup Loading + What Games Work/Don't

This thread is outdated
A lot of information in this thread is heavilly out of date.
If you have time, and have Staff permission, feel free to edit this thread and remove this statement once necessary.

Some information that needs to be addressed:
  • SX OS and Atmosphere now supports proper LayeredFS, instructions for using it has changed since this tutorial was made
  • Supported Firmware information is out of date
  • LFSKit needs to be updated to properly support non 5.x.x firmware
  • Compatability chart needs to be re-made

Picking a Donor Title and getting Donor TitleIDRunning Game Backups!


    1. A donor title is the application we will run to open the backup.
      Pick a game you don't care about (Download a Demo or a free game from eShop, for example Octopath Demo)
      saves are something no one knows much about, we don't fully know where or how they are stored.
      They might overwrite the donor titles save, so seriously pick a game you DONT care about, not a game you rarely play.

    2. I also recommend picking a donor title/game combo that has been tested and reported working just so you know if YOU did something wrong or not.
    3. Find the TitleID of the donor title you chose from http://nswdb.com or http://switchbrew.org/index.php?title=Title_list/Games
      Region must be the same, choose the TitleID for the base-game NOT for the update title, even if your updated.

    1. Once again, boot into Hekate-IPL (Step 1).
    2. Enter "Launch firmware" and select "RomFS".
    3. Your now in your system's home menu.
    4. Open the Donor Title you set the TitleID of on that folder and .npmd file earlier.
    5. The game will load up flawlessly.
      If you opened the Title lets say, Fortnite, and Fortnite booted, the titleid of the folder in sd:/atmosphere/titles/{fortnitetitleid} doesnt exist, or doesnt start with 0100.
      If it gives you an error screen, either you didnt edit the main.npmd properly, or its an incompatible title/donor combo.
    To see which games work and which dont using which donor titles, look below.
    If you notice that you used a combination of Game and Donor title that isnt in the list below, post in the thread and I will add it. (look under to see what I need to add to chart).


Troubleshooting

  • Black Screen/Infinitely Loading
    Leave it for around 5 minutes then press the home button and go back into the game without closing it. Often this can do the job.
  • Freeze when Loading
    Close the game and try again, its a common occurence, you may have to try up to 4-5 times before getting it to work, sometimes you may even have to reboot between retries.

There's no demo for that is there? Guess i'll have to buy that then. Thanks tho! Any chance you know what this means "Manual using the 83c9747 commit of Atmosphere" was gonna run Zelda BOTW & the method description is that.

No that's the demo I'm referring.
Edit: Try downloading sdfiles from tomGER

VOEZ saves up to 2MB that's why I chose it. You could try it with happy birthday demo or super one more jump demo (those have good save size too)

Good to know! Thank you again, i actually have the happy birthdays demo so if i can't get VOEZ. I will try that one next after.

Check your keys, do you have them all? Also try updating hactool to version 1.1

My keys are complete and hactool is also at version 1.1 and also this is the command I used
.\hactool.exe -k keys.txt --baseromfs="romfs.bin" --romfsdir="update" .\update.nca

Hum...I'm not sure why the update is in your command. Try this instead:

hactool.exe -k keys.ini -txci --securedir="xciDecrypted" "%~1"
dir "xciDecrypted" /b /o-s > nca_name.txt
set /P nca_file= < nca_name.txt
del nca_name.txt
hactool.exe -k keys.ini --exefsdir="xciDecrypted\exefs" --romfs="xciDecrypted\romfs.bin" "xciDecrypted\%nca_file%"
del "xciDecrypted\*.nca"
del "xciDecrypted\*.tik"
del "xciDecrypted\*.cert"
pause >nul

Create a .bat file with this, drag & drop your xci onto it (the xci file should be in the same folder as the .bat file, hactool & your keys).
