Homebrew svdt: save data explorer/manager

[ihaveahax]

Thanks! It seems I was missing the asr.dat file.

I'm now currently dumping AC.

BTW, can this be used to put the save file back? Or I must use another tool?

you can change any of the files in the game's save (so backing up and restoring). it also supports "fixing" the secure value for digital games like ACNL.

Awesome, thanks for the help!
Just dumped every save file I needed.

Now I can format my SD to use emuNAND without grief.

I am using this for the first time with a gateway 3ds card and my games are card 1 based games that make .sav files. I also have super mario 3d land installed on the sd card that is inside of the 3ds. I started this up with super mario 3d land and i go inside of it's folder and i find a gamedata.bin file. I then restart it and load up both super smash bros and sonic generations but when i go inside of those folders, i do not see a gamedata.bin file and when i click on my gateway .sav files nothing happens. Does this work with card 1 type games that has it's save file seperate from the game as a .sav?

I get a red screen even with asr.dat.

do you get the ability to choose a game? if so, what game are you picking?

AC:HHD.

 

[ihaveahax]

AC:HHD.

assuming you're using a digital copy, this game can't be used with svdt since it's using 9.6+ encryption. sorry

Also does it only work with gamedata.bin files?

>< pretty much the only game I wanted to keep the save of before formatting & downgrading.

This doesn't work for gba vc games right? I get a red screen on my fire red.

not really possible due to how they work.

okay thank you. Hopefully a way will come out someday.

I guess svdt could be redesigned to work as savedatafiler, but that would need directly reading the save directories, while it now uses the savegame partition functions that usermode provides (thus having access only to that game's savedata).

It might be possible though to modify HBL in some way that svdt is launched under the process ID of 9.6+ games but with the decryption set, since there's already a user made database of 9.6+ key (seeddb.bin I think).
I don't really know how would that work, I expect hax 3.0 to deal with this in some way. I think I'll ask at 3dsdev, see what I get (don't think I have the skills to implement it f it is possible though).

You don't need to format before downgrading. SD card "might" be advised to be formated, but you can backup your sd data on pc and restore it after downgrade.

After you get emunand with a copy of sysnand runing use savedatafiler to get you HHD data, then you can format sysnand, emunand or whatever and restore.

formatting I think is the only solution to some New3DS users who get soft bricks during downgrading. at least until something else comes up.

Well, now that 1.04 is up I guess it is better to ensure the downgrade.

BUT a decrypt9/emunand9 version that uses memchunkhax2 could make a sysnand backup before downgrading, so nothing would be lost even when formatting sysnand since you could use your previous sysnand as emunand. But this is going offtopic.

Decrypt9/EmuNAND9 relies on ARM9 for raw NAND access, and the only ARM9 kexploit above 9.4 is ntrcardhax I think. anyway...

When I try copying Story of Seasons saves from Retail Cartridge into cia, I got this error message:

svdt has encountered an error, and has halted to protect your data. Press START to exit.

How can I solve this?

 

[gangs_08]

can we dump our save files from legit cia's with this tool?

Probably you haven't made a savegame yet in your cia version of the game.

The way svdt detects free space in the savegame partition I think is by extrapolating what the contents of the partition and their size is, if you try to write something bigger it will error out even if there's free space.
If there's no savegame when at svdt's boot, you can't write anything.

This could be adressed since there's a (working) free save partition space function, or at least prompt a warning instead of the standard write error, but for savegame you most likely are overwriting or deleting to reset the save, so the problem were you write to a blank savedata partition is not common.

Except for happy home designer, yes.

This doesn't work with AVGN's game
