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This thread is outdated
A lot of information in this thread is heavilly out of date.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  • Supported Firmware information is out of date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

Try using xci2title
Same error, didn't work.

Good fuckin' question. Please report your findings in detail.
I believe it has something to do with the checks that are implemented for certain games - and for other games / demos not. ¯\_(ツ)_/¯

For example:

Donor: Happy Birthday Demo (Demo ID: 010069700AF9C000; Game ID: 010083600AE9E000)
Game swapped: Fire Emblem Warriors

I used game ID instead and it worked.

Thanks. This will have to do for now, hoping we get a nicer/easier tutorial for this sorta thing. In the future of course.

Yeah definitely! But once you're tools are in place, it's mainly drag & drop.
Also things are getting more stable now. Using version 5 of tomGER's SDfiles I've had zero crash switching games:yay:!

Since it's a type 2 game, may I suggest you exract the NCA file with xciexplorer and decrypt that?

Ocean horn demo works . Made it to the second boss so far
Can you please tell me how you decrypted the xci?

Don't know about autosaves, but I downloaded the game titled "+ Update V1.50", but when I launch it, it's just on 1.0.0 :unsure:
So I downloaded a fake, or I did something wrong in the process ..

So all i need to do is: get the keys, get the xci file, get the title id and use xci2titleconverter to create title folder then use it to replace the one in atmosphere/title?

I got this error while decrypting the xci also only create a folder with tittle id romfs.bin but nothing of exefs. I tought it was my keys.ini but I rebuild them twice.
"you can not find a part of the path tittleid / exefs / main.npdm"
I think something about section 0 corrupted also in cmd window
did you ever find an answer to this?

--exefsdir="*FULLPATH*\exefs"
might help. Hactool threw that error for me when it was not able to create the folder or could not find it.
Create an exefs folder and copy the path, just in case. The resolved it for me.

Also use quotationmarks if your path has spaces (e.g., "c:\foldername with spaces\exefs" instead of c:\foldername with spaces\exefs).
