Homebrew 3ds extdata dump and restore tool (extra data editing!)

[WateredFire19]

Check http://3dbrew.org/wiki/Extdata#NAND_Shared_Extdata Look at the description for 0xf000000b. It says it contains "clear text Mii's". Does the mean we can hex edit it or something?

Making a play coin setter now.

One already exists. For Gateway and CN/NH

"System apps with a certain access right can mount arbitrary extdata."

Does this mean we could make a "system" app and modify all of the extdata via GW?

Maybe even via Ninjhax. Who knows.

Here is the code of my Mii and the Rainn W special mii.
EDIT: For some reason, after editing the names and retoring the CFL_DB.dat file, the name restores to normal. And when i re-dump the CFL_DB.dat, the names also revert THERE too.

That MIGHT be a big thing! Remember on the Wii, those special colored symbols? http://i349.photobucket.com/albums/q364/MikeYoshi/all_symbols_highquality.png

Maybe we could do this for 3DS!

Yay ive accomplished somefin'! But does the 3DS's font have those?

Yeah, I'll look further into this tonight. You said it reverts? Probably because we need something like the "enable theme-cache" like on the Theme extracter.

Right. When i modifiy the names in CLB_DB.dat and restore it onto my DS, the names do not appear different in Mii Maker. And then if i re-dump the CLB_DB.dat, it does not evem mantain the edited names.

Just making sure- are you sure you correctly edited the Miis name?

R a i n n W

There is spaces between each character.

Yup. thats what ive been doing. And for every real space there are 3 spaces. Like Bewtween Rainn W

 

[WateredFire19]

I've found something interesting. If i modifiy CFL_OldCB.dat the same way, It deletes my Mii's. Strange.

Okay, I see. But aren't miis linked to NNIDs? Maybe if it sees an edit thay isn't supposed to be there, it goes with the NNID Mii snd overwrites it?

We're leeeeeearning!

NNID's? Never heard. MrCheeze said that his extData tool can access shared extData where Mii's are stored

That is interesting. If we renamed CFL_OldDB.dat to CFL_DB.dat and CFL_DB.dat to CFL_OldDB.dat, the edits would take effect.
