Homebrew Question How do I datamine/edit/replace game files?

[TylerZM]

So normally I'm a Wii U modder and the main thing I like to do is datamine/edit/replace game files or saves.
I wanted to get into Switch modding and I've successfully gotten Fusee Gelee working.
What would be the best way of doing this? I can't seem to find a thread explaining it.

First step would probably be trying to open XCIs as an archive.

I have no idea how to do that, but it sounds fimiliar. I'll look into it and let you know if I get anything done.

unsure if you can dump games yet but you can find the roms and then use XCICutter for save export and import either use Checkpoint or Yallarenuts

I figured it was possible because a few Switch titles have been datamined and gamefiles have been uploaded, and I heard someone was model importing for Mario Odyssey. I'm not concerned about save editing just yet

Do you know how I can dump an XCI from a game?

the real question should be when can we mount games directly on the Switch so only specific files are dumped and then load patched versions of said specific files without having to dump and load a copy of the whole game's files on the SD card?

I'm looking for something more like SDCafiine than like Loadiine.

exactly

by mount games I meant mounting them so they are accessed like a set of file directories on the Switch where you look for specific files and copy them to a folder on the SD card for editing and modding purposes

I believe there was a similar tool on the 3DS that no longer works because of homebrew launcher updates and such but it did the same thing for 3DS games where it mounted them like a set of file directories which could have specific files targeted and dumped without dumping the entire game all at once.

The best thing I would be looking for is essentially a Switch ver of ftpiiueverywhere. Not ftpd because thats only for SD files

once again thats not a thing and would most likely have to wait for atmosphere-NX to get released
