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

[RachelB]

But what already there is " FE 98 ".

Yes, change it to whatever new checksum you calculated after editing the file.

 

[WateredFire19]

So what i do is: 1. Replace Mii id with Huntereb's 2. Find checksum 3. replace old checksum at 0xc81e with new checksum 4. save and restore?

 

[RachelB]

Yeah, that will work.

 

[WateredFire19]

Didn't work. Still red pants.

 

[MrCheeze]

Strange, my Special Miis are editable and Streetpassable, though you can't get a QR code for them. To be clear, the only thing you need to edit besides the Mii ID is the disable sharing bit. Also, I don't recommend doing this with your primary Mii, since they're required to be sharable - mine just changed back out of his gold pants.

Oh, and it's probably identical to Rachel's, but here's my checksum fixing program as well. Source included. https://dl.dropboxusercontent.com/u/183608682/mii_checksum.zip

 

[WateredFire19]

What line does the Mii id go? The one someone else posted had two Mii's in it but i only have one

For 64 bit only systems?

That's unusual, I couldn't get them to work with Streetpass under normal conventions.

 

[WateredFire19]

IT WORRRRX But when i try to do my personal mii it wipes out all my mii's

 

[MrCheeze]

oh yeah. one more thing. when editing the Mii ID, it's probably best to ONLY change the first digit from 9 to 1, and not mess with the rest. Just in case the rest gets used for something.

actually, two more things. this may be obvious, but it's possible to backup CFL_DB.dat and restore it later. so probably best to back it up before changing anything, despite the system having its own builtin backup.

 

[gudenau]

Um. This tool already does that, that's what the folders in the f0000000+ range are.

Oops, I meant the BOSS data. :-/

 

[MrCheeze]

Ah, alright. I wish you luck then!

Mind posting the data for one of yours that can be streetpassed/edited?

 

[Huntereb]

Let me give editing one like Cheeze did a try, I just based mine off a Nintendo Mii.

The two bolded digits are the only ones I manually edited (9 to 1, and 2 to 3). The rest was a preexisting Mii, that originally had sharing and copying enabled.

EDIT: The first bolded digit should always be 1. The second one should be one higher that it used to be (i.e. enable the least significant bit).

 

[WateredFire19]

MrCheeze what points on hex do they start and end?

We're getting closer.

 

[Huntereb]

Didn't work on my end, deletes the Mii. Not sure exactly how it's determined, but I have a way of doing it so I'll stick to it. I'll follow this thread, kinda curious where the "Console ID" is stored that I seem to be writing over with all of my 0's. That's probably what determines which Miis can be used in Streetpass, whether you created it or not.

 

[themperror]

So ehm.. Now I'm at a loss, Is it possible to have your MAIN mii have a gold pants and thus have it in the streetpass games and show up at others's streetpass?

Ah, just editing those two bytes worked!
