Hacking SaveDataFiler-Like Extraction of System Saves?

drfsupercenter · Jul 16, 2015

Is this possible? I noticed that SDF only shows saves stored on the SD, not on the NAND. There are lots of saves that affect useful things, like home menu notifications, the activity log, and so on.

Currently the only way to view the contents is to xorpad the NAND FAT16 partition, extract the 00000000 raw file and hope you can parse it... far from ideal.

I know FBI shows apps both on the NAND and on the SD, where DevMenu only shows SD apps (plus the browser for some reason), so in theory it would be possible to do the same for saves.

I don't care if it's "open source" or not, like some people were looking for... just wondering if such a thing exists.

Bump for interest

This is a slightly old thread, but soon @smealum's tdvs ("Test Data Visualization System") will allow you to export and import saves for games. As to when it's coming out, well nobody seems to know, but it might happen within the next few days.

Nice... does it work on system titles too?

What save are you trying to access?

savedatafiller as .3dsx is possible to compile in the format ?

Don't think so since it's Nintendo developed. That's why we're waiting for tdvs, which is pure homebrew software.

But exist this program in .cia format

Because that's the format it came in, and is to be installed? .3dsx is not the same type. Besides, the current ironhax/tubehax/ninjhax 2.x can only run .3dsx.

Yes, installed in cfw. I don't understand nothing about programming. I hope Smea release TDVS soon.

Going by the ironhax installer.3dsx .xml file, it would seem so (this app seems to be a stripped down tdvs). It has a mediatype option, which corresponds to 0=NAND, 1=SD, and 2=cart according to 3dbrew. I can confirm cart and sd media work. I've done some messing around with patching it to write arbitrary files to arbitrary games and had some success. Haven't tested NAND save writing yet.

Using Ironhax source is possible to make a TDVS ? Smea said as release soon.
