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This thread is outdated
A lot of information in this thread is heavilly out of date.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  • Supported Firmware information is out of date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

Tried Kirby over Kirby Demo
Bam! Nothing but black screen!
I get it now! Demo games without save function don't work!

Wow! Such a great tool to save all trouble of trial and error we're going through now! Thanks.
The only thing missing is a search function in the view for specific games (especially useful if trying to check compatibility with a certain game!)

That's why I made the spreadsheet and the google form. Makes it easy. Even has a nifty viewer now.

The following are links to the individual thingies

So, for the exact steps:
Launched Hekate IPL
I did Enter Launch Firmware, and selected RomFS

After that, a New Window will come up with Patching kernel initial process.... and well, here my switch stucks for 4-5 seconds, and then a black screen occurs.

Any suggestions?

I've the same problem man, if you find a fix please update your post ! :)

Maybe there is something wrong with the kernel patch.
It doesnt matter what i do, evertime at the "Patching kernel initial process" i get a blackscreen.

Whenever I boot RomFS, this happens and it stays on this screen. imgur(dot)com/DzviFdv.jpg Anyone know what I am doing wrong or what is going wrong? I did my best to follow the instructions to the letter.

New user, cant post links sorry.
