Homebrew Edit NAND Save Data?

[gudenau]

I would like to be able to edit save data that is stored on my console's NAND, how should I go about doing this? (From NINJHAX 1/2 would be best)

The only way at the moment is SaveDataFiler. TDVS may be able to do this in the future, but not released yet.

I guess a better question is:
How do I mount a diffrent title's save archive.

Maybe dump it's memory with NTR?

EDIT: Wait, what are you doing with the home menu?

EDIT2: All the nand has is the Launcher.dat. What are you planning?

I already dumped the memory, I still need to edit the save data.

Things, great for us, bad for Nintendo. Mwahahaha*cough*

I am working on stuff than can brick a 3DS, it could also allow one to do a cold boot into a CFW.

PM me the details. And you may be able to do it with a nand dump and a fat16 xorpad.

The save data is packed and has hashes and signitures and junk. :-/
Also, as soon as I get any progress I will make a post about it. No need for a PM.

Oh. I almost said to ask the devs of SaveDataFiler. Yea, how well would that work? Anyway, maybe TDVS?

Not out, as far as I know. Plus, it appears as though it uses a diffrent archive id all together.

Yea, not out yet. And archive id?

In order to access a file you have to open an archive; which can be a file on the NAND, the NAND, the SD card, etc. It works kinda like mount in Linux.

Ok, so we just need to find the archive id, right? And then we can mount it?

I need to figure out what perms I need aswell as how to use the archives, I just used the CTRULIB stdio stuf f before.

Don't worry about perms. You should just be able to run bootstrap before it. Or some sort of that.

I am not sure if that grants all of the FS stuff, I k ow it patches SVC and service stuff perms.

You think we could cause any damage by blindly probing archive ids?
