Is there someone know how to edit the code in main file of exefs folder.
Or some tools to do it.
Please, I need to translate a game to another lanuage, so I have to rewrite the code so that I can set the path to my own font Atlas.

What you need:
> nx2elf & elf2nso for decompressing and compressing main file
https://github.com/shuffle2/nx2elf
https://github.com/switchbrew/switch-tools

In attachment i uploaded compiled binaries for this tools.
Decompress.bat will decompress main to main.elf
Compress.bat will compress main.elf to main.nso - just rename to main
Ignore errors if it will show something - it's still good to edit.

> IDA Pro 7 (not free version) with SwitchIDAProLoader or nxo64.py for deassembling (it's loading original main file, don't try to open with them decompressed main files)
https://github.com/reswitched/loaders/
https://github.com/pgarba/SwitchIDAProLoader

And just wait until app will show "idle" in left lower corner of app (it will play windows jingle). If you do something in IDA when it's deassembling code, it will slow down dramatically.

Which redists are needed to run nx2elf?
I have installed c++ redist 2015-2022 for both x86 and x64 and it still doesn't launch because of missing the following files:
UCRTBASED.DLL
MSVCP140D.DLL
VCRUNTIME140D.DLL

Thanks in advance.

I used Il2CppDumper GUI 2.1.0 with main(.nso) and global-metadata.dat and got these files
Can I continue with main(.nso)?

This "advise" is outdated as f.
For IDA use this, read readme

https://github.com/TSRBerry/nxo64

Then when loading original main it should detect by default that it's compatible with nxo64, don't change architecture

thank you so much :)

after installing nxo64, I tried to open a plain main file and got this error message :(
what`s going on?

    @BigOnYa,
    I don't listen? What didn't I listen at? I just want to know all the possible risks on that part
  • A @ ATEMVEGETA:
    Hayato even said it's dangerous to backup the save files to CFW
  • A @ ATEMVEGETA:
    how is this dangerous? A ton of people did this it's the most common thing to do with CFW
  • BigOnYa @ BigOnYa:
    Then do it

    dude, whatever

  • A @ ATEMVEGETA:
    For example, HOW is is risky to get banned if you extract the save files to the CFW?
  • A @ ATEMVEGETA:
    isn't this proccess be done while you're offline?
  • BigOnYa @ BigOnYa:
    We are not Nintendo, so we don't know exactly how/why/when they ban, but better to stay on the safe side and not do shady stuff, if you don't want to be banned. Hayato is one of the most knowledgeable ones here on the subject and I believe what he says.

  • A @ ATEMVEGETA:
    @BigOnYa, Yes ofc we don't know how Nintendo bans work, but if there are situations where a lot of people have tried safely then we can at least assume that this path is pretty much safe. To say don't try anything homebrew relative just to be safe forever is the easiest thing to say to someone. What I am trying to figure out here is with which cases and what actions got most of the people their bans for.
  • A @ ATEMVEGETA:
    Most things I can find resulting to a ban is save-editing reasons, like Pokehex, etc, and going online afterwards.
