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.

I think i figured out the problem. I tried extracting ARMS and it worked, later i realized that what ARMS and Splatoon 2 had in common were that they required low firmware. So i checked the keys.ini and i found that I only had masterkey 00. However, I tried adding the other masterkeys and tried to decrypt, the application instantly gave me the error, how do i get the keys.ini with all the masterkeys?

the better way to see titles 100% without fail is DEV MENU... very easy and you can take pictures or whatever... install all games and make your own list

I started using this method on LayeredFS and it works beautifully. I use it in airplane mode than I reset the switch, clear the logs as a precaution no ban yet.

 

[Rainbowfied Pokemaster]

if you run the donor "Splatoon 2 Demo" and it actually loads the donor itself "Splatoon 2 demo" (in this case)... that means either you did not have the files setup properly (\\atmosphere\titles\<title id>\exefs and romfs.bin)
or you did not run the right option when Launching Firmware
(for me, in CTCaer mod, it shows "CFW, RomFS, Stock..." example... only RomFS firmware runs the backups)

Welp, now I'm getting "Failed to launch firmware" when booting RomFS

 

[EonFenix]

is your sd card and files this is why i switched to switchblade no need to run romfs just load switchblade and it should work.

Is Super Mario Odyssey title id offset 0x430 or 0x440?

 

[skflich]

Anyone got Mario Tennis Decrypted? I am running into multiple issues with xci2titleconverter, but I can extract all the files with xci explorer. Any ideas?

 

[Frexxos]

I just read about Mario Tennis Aces in a different Forum the following:

I have tested it and it is CONFIRMED WORKING WITH LAYEREDFS with Fornite as donor! (Edit: SAVES WORKING!)

Maybe this will help someone.

 

[Kirby567fan]

i cant find happy birthday titleid :/

The demo version titleid is 010069700af9c000 and for the full game its 010083600ae9e000

Decrypt with hactoolgui. Correct me if I'm wrong but you'll only need the largest nca in the secure partition. Just in case you were extracting everything.

Select extract nca -> Output: Generate emulator ready folder -> Yuzu

That'll decrypt it the way you need.

Oh you'd also have to

• Create the exefs folder
• Put the files that go into that folder into to it
• rename RomFS.romfs to romfs.bin

Yeah got the .nca file but when I use hactoolgui it pops up a cmd box and quickly disappears and leaves the folder blank.... grr

Got it to work by manually using hactool. Was able to execute the following command. hactool.exe --romfs=romfs.bin (DIR\nameof.nca -k (filenameofkeys) then I did hactool.exe --exefsdir=exefs (DIR\nameof.nca -k (filenameofkeys). Now i just got to put the files in the folder for the the title ID I want and also had to patch the main.npdm with the Title id using http://carlus.altervista.org/nx/title_id_patcher.html and now it works.
