Hacking Discussion Switch backup loading using Atmosphere-NX LayeredFS

[MrGizMo]

Today is going to be a fine day for the Switch

 

[longxa762]

Just read a bit of the OP, is it a real backup loader
or more like a Switch Loadiine?
I'm a bt confused here

Seem to me it work by replacing the game you currently have with another one, not running the backup directly

It was my own personal dump - Tiny Barbarian

Thank you very much! Great!

I did everything but I don'T get this part, can someone explain what to do? Opened with Notepad++ but which line do I need to change?

5) Edit titleid in main.npdm (in exefs) to contain target title id (this might help ...)

 

[Zumoly]

You know what will be dope?
To actually replace the demo game with the full one!
I'm guessing cart games won't work with this because...redirection?
Anyway nice pof.

You need to use a hexeditor like HxD and change the title id in the ACI0 header. Look at the wiki page.

No worries. Doing a scene dump next, with an injected cert. We'll see how that goes.

Edit - Tested Lost Sphear. Boots but graphical issues until you home button out and back in.

XCI dumps do work with this.

I have tried with a big game (6go) and it keep loading the games for severals minutes. Nothing works lol

So you can download a bunch of demos and then replace each demo with a game that you actually want. Then it's just a matter of remembering which demo is which game. Or is there a way to change the game thumbnail also?

 

[dovah]

another tip,
when patching main.npdm and you don't want to read the NPDM wiki (on switchbrew), you could just search your title id in little endian mode (reversed bytes).

so, for instance, if you have this title id 0100000000010000
search in your hex editor for 0000010000000001 and patch properly following the same format

I'm sure at some point yes!
But what'lll be inconvenient is to run out of demos.
Maybe a homebrew to install a blank title might help?

You can't install homebrew apps as title to home menu just yet.

Yes.
Extract the secure partition from the XCI and the biggest nca there is the one you want to use with my tutorial.

So, I've setup hactool, I decrypted a Puyo Puyo Tetris xci. I'm looking at a bunch of stuff.

what'd i do wrong

Switch backup loading is here: [prebreak]1[/prebreak]

1) Get a title id of any game you have installed from http://switchbrew.org/index.php?title=Title_list/Games (this is your target titleid)
2) Create a directory on SD : sd:/atmosphere/titles/*target_titleid*
3) use hactool to extract the romfs.bin and exefs files from your main nca from the game you want to run instead of your target (its in secure from XCI - the biggest one)
4) put romfs.bin in sd:/atmosphere/titles/*target_titleid*/romfs.bin, exefs files into sd:/atmosphere/titles/*target_titleid*/exefs/
5) Edit titleid in main.npdm (in exefs) to contain target title id (this might help http://switchbrew.org/index.php?title=NPDM)
6) run a fs_mitm containing CFW release, run your target app (https://gbatemp.net/threads/how-to-get-layeredfs-working.507460/)

Note that saves don't work for me atm, you should wait for mememenu/similar.
Minecraft works, others not tested.

nothing wrong, romfs.rofms is, well, your romfs file.
the rest are exefs files
