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• Supported Firmware information is out of date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. 
   
   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.
2. 
   
   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.

Hey !

Maybe it's unrelated but when i launch "RomFS" on hekate, it just stay "loading" until a whitescreen of death appears...

 

[FearItSelf23]

If I use this I get an error about path for exefs and if I try just using xci decrypter I get the xcidecrypted folder with just the romfs.bin. It wont produce an exefs folder/file.

Chill!
The thing is:
-When you launch romFS from the launch firmware section of your payload, you need to directly go for the donor game of the game you're launching (nothing else! no homebrew, no other game!)
-An error usually means either you already launched a donor game or your donor game is not compatible and you need to use another one.

I cannot get a game to run for the life of me, I followed everything down to the letter on these tutorials but whenever I inject pokken into fortnite, I always get the same error, something went wrong/turn off system, I just don't understand what I am doing wrong, I followed ShinyMK's hekate cfw/RCM smash tutorial aswell to see if the version of hekate I was using was wrong or something, but nope same error as usual, the only thing left to try is to format my sd card and try again, but that shouldn't be a problem because I am sure I formatted my SD card as exfat32 before doing kind of CFW/Homebrew stuff with my switch.

If anyone can help it would be much appreciated.

--------------------

Guys you know what causes the "The software was closed because an error occurred" error? It comes immediately when i try to start the Game.
I tried Skyrim with octopath traveler demo as donor. It should work according to OP.

Thanks for the quick reply, but I don't seem to see any kind of romfs option when I choose launch firmware on the hekate payload menu, okay now I definitely think I am doing something wrong, maybe you could point me in the right direction?

 

[FearItSelf23]

Why do I get section 0 is corrupted and unhandled errors every time even when I follow the instructions on a clean SD card? Unhandled error is always unable to find path for main.npdm. I feel like something is missing from the instructions.

You need to prepare your SD card for LayeredFS and also put a line of code into hekate.ini on the root of your SD card.

Maybe you're still missing some keys.

Not all games work with each other m8, try ones confirmed to work.

 

[M-Gardevoir]

After choosing "RomFS" in Hekate, it froze like this.
Then a white screen of death appears. Pls help.

I tried fortnite to run pokken because it said in the table that fortnite was a good donor title for it, maybe I'll try something else this time.

 

[Dvdxploitr]

Game: Shaq-Fu: A Legend Reborn
Donor: Fortnite
Saves: Yes
Firmware: 5.1.0


Yes, the first load screen for the game is about a full minute!! I typed this post in the time it took to load to the main menu!

 

[cherryduck]

I must be doing something wrong. When I go to the "launch RomFS" option I get a weird pattern of white lines on my screen, eventually "Rebuilt and loaded package 2" and "Booting..." appear within the mess of lines, but nothing happens from there, just sits on that screen. Also, I get a different key set if I use BOOT0 and the other file from the latest firmware, versus using my files from my 3.0.1 NAND backup. With the newest files, I get keys 00 and 04 on everything, with the older 3.0.1 files I get 00 and 02. Only my keys dumped from the older firmware files can actually successfully extract XCI dumps.

 

[Zumoly]

FW version?

Hm...Your firmware is good
What about you setup?
How did you prepare your SD card? What files did you put in there (maybe you're missing one of them)?

 

[M-Gardevoir]

Well i followed all the steps in the APP flawlessly. No error or anything like this.
Just i've found something weird : fs_mitm.kip have 0kb... in [SDCARD letter]\modules\romfs
Also have 4 files :
- fs_mitm.kip 0kb
- kernel-patched.bin 455kb
- loader.kip 139kb
- sm.kip 149kb

Hope it help

 

[Zumoly]

fs_mitm.kip 0kb

That's not right! Try getting it again! It should be 138 ko

 

[M-Gardevoir]

Tried 4 times, always at 0kb.

There no download source for the files ?
