ROM Hack Question Copy saves between users

[D-Jay]

Hey guys n girls,

just a short and simple question: Is there a way to copy saves between user profiles?
Any tool or something else?

Thanks :-)

Yes, create a save on the profile you want to transfer the save to. Then backup both saves with Checkpoint. After that, on the pc, copy the save files from the original profile to the new one.

 

[D-Jay]

I know about Checkpoint. I want to prevent using homebrew because of Nintys bans. :-/

The "easiest" way would be to backup your current legit NAND, go do your stuff it in airplane mode with Checkpoint, then when done backup the modified raw save from your NAND to your PC, restore legit NAND back, and copy the modified save back (that is in SYSTEM partition /save). It will work.

 

[D-Jay]

And that's what I've done :-)

 

[alkar]

Happy to help.

 

[D-Jay]

Uhm... I think I was misunderstanding your hint.
Could you please explain how to copy the save files back to the Switch?

I've done a NAND backup with Hekate of the clean NAND.
After that I've made a backup of the saves with Checkpoint.

So... after restoring the clean NAND... how can I replace the saves exactly?

 

[alkar]

you need to backup/mount your modified NAND and copy the raw modified save that is in the USER partition (not SYSTEM, sorry my mistake) to your PC. Then after restoring your clean NAND, copy it back (if it needs renaming to match the old save, rename it).
Usuually you can isolate the file by sorting the SAVE folder by date. The file name for the raw save should be something like 0000000000000XX (some numbers or letter).

 

[D-Jay]

Okay, HERE is what I was missing.
How do I mount the NAND file to my PC?

 

[alkar]

Use hacdiskmount.

Obviously you need to dump your bis keys too. Which is safe since it’s done by a payload in rcm and not by home brew.

 

[D-Jay]

That worked, thanks so far.
My next question... Checkpoint gives me two files, a Common,bin and a File1.bin... so how do have to inject / convert them?

 

[alkar]

extract the other save you wanna inject these to, replace the common.bin & file1.bin on the other save, and reimport these on the other save.

When this is done, do what i've told up above.

 

[D-Jay]

OMG... I'm so sorry. I really didn't understand what you mean. After some coffee it's clear. Sorry for my foolishness!

How extremely inconvenient to go through all of this just because you fear being banned for homebrew.
Has anyone actually been banned for using homebrew only? No backups, no cheating, no illicit nsps. I don't think so.

 

[D-Jay]

You're absolutely right. It would be a one time scenario because I played with the wrong user on my switch.
Doing this everytime would be a pain. ;-)

 

[alkar]

It’s inconvenient indeed but that’s the only way to be 100% safe. Maybe it is not worth the hassle but let’s not take any risk if there is a 100% safe solution ?

 

[D-Jay]

100% safe just if you don't play xci and install nsp images ;-)

And who knows if Ninty checks the hashes...

 

[D-Jay]

Okay, the save copy method doesn't work for me.
I've copied the save and saveMeta folders, started the game and it stucks at the Nintendo / Switch logo loading screen.

As soons as I start the game the second time, the old saves were removed and I have to play from the scratch.

 

[alkar]

savemeta isn't needed, I didn't try the trick though but it should have worked. Sorry :/
