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This thread is outdated
A lot of information in this thread is heavilly out of date.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  • Supported Firmware information is out of date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.

Check this out.
Not actually banned, and I couldn't find more info on it. Rebooted to stock FW and played Splatoon 2 just fine. It was pretty weird.
What game were you injecting and what game were you using for a donor? I take it you tried to go online with the injected game?

FE Warriors works on top of Fortnite. Saves work too. What's surprising is the game loads even before Switch clicking animation finishes on the load screen.
