Is it possible layeredfs is failing for some titles because of the titleid offset o.o Holy fuck think about it, whats a title that hasnt run at all yet? 1-2-Switch. What offset is that using? 0x430, not 0x440 like almost every other title.
If anyone can, try verify im correct on this topic.
I dont have lfs source so I cant do any tests.
It's very possible the titles that isn't running is caused by this.

How to use LayeredFS for Backup Loading

Firmware Supported: ONLY 5.x.x
Use the PRAGMA LFS Kit below.

PRAGMA's LFS Kit

DOWNLOAD
SOURCE

• Go from NOTHING in your SD Card to playing a game backup in a few clicks!
• Decrypt .XCI -> romfs/exefs folder with main.nmpd auto edited aswell as folder's name auto renamed to donor titleid
• Download NOTHING except LFSKit!

ENJOY!

• Picking a Donor Title and getting Donor TitleID
• Running 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. Look below for the Title ID or google it and remember it, jot it down on Notepad, we will need it later.
• 
  
  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).

Working Titles - DO NOT ATTEMPT TO USE TITLES ONLINE!

If the title is infinitely loading or black screen, leave it for roughly 5 minutes, press home button, go back into the donor title and see if it loads.
Some games just need a little push.
I have a theory that some games work and some dont due to SD Card and LayeredFS filesize reading limitations.
Of course, I could be wrong, but is it really a coincidence most of the BIG games dont run?
If a title FREEZES when loading, just close the game and try again. Try 3-4 times. If it still freezes, try rebooting.
Some testers had freezes on games for ex: DOOM + Fortnite(donor) yet some testers did that combo, and got through.
