ROM Hack 3DS Mii Modifier (Computer Utility)

[Ryccardo]

Thanks! The text under your table sounds perfectly fitting to some of the unknown values in mine

 

[SomeGamer]

I just saw this thread and the new Mii page on 3dbrew. I added all my findings on Miis (mainly about which part can vary how much).
It's all from NTR debugging so not really useful as is.
I'll map those NTR addresses to decrypted Mii offsets when I'll get some time.
If some are interested in Mii research I have a Java app that can concert a QR code to a an encrypted .bin (and vice versa), a small HB that unwrap an input.bin to output.mii (and wrap an input.mii to output.bin), not sure that would be useful, thus not posting if no one interested.

Just post your app! I'm sure there's interest for it, including myself.

 

[Goombi]

I take note of that. That will be tomorrow, gotta sleep and I have to remove debug shit in main() and all before throwing it in the wild.

 

[DrakeLyon]

@GamerDudeK upon taking away golden pants from my Primary Mii with this program, I'm unable to re-enable Sharing again. Is there a way you could possibly implement a feature to fix this for the primary Mii when disabling golden pants?

 

[Goombi]

Okay I finally got my shit together:
Here is the QR code encode/decoder (and futur encrypt/decrypt/edit app). Did I said that was in Java? Well I wanted everyone to enjoy it without having to install Java.
And here is the Mii decryptor. Use the QR code decoder to get a .bin and place it in the homebrew folder as input.bin.
Launch the HB and choose the option you want. Basically it's a APT:Wrap/Unwrap wrapper.

Hope those tools will help!

EDIT: Those expect decrypted Mii to be 0x60 bytes long. If you read your CFL_DB.dat they are 0x5c bytes long. You can add 4 null bytes, none of my apps nor the 3DS checks it but those bytes are required when reading the QR code.

Nice! Is there a self-hosatble version?

So what exactly can we do with this?

 

[Goombi]

Well you can't host it offline for now, I call Google chart API to generate the QR code. If you want to host it elsewhere, just download the page, your browser should do the rest.

Well not much outside of doing research of offsets and making special Mii QR Code.

Thanks! I had a fear it had an online dependency. I don't know why, I like to host these kinds of things on my LAN.

I understand that very well, removing that dependancy is on the TODO list, I'll @' you once that's sorted out

How about a "Mii research lab" thread instead of being topic-borderline?

 

[SomeGamer]

How about a "Mii research lab" thread instead of being topic-borderline?

Great idea, after all, this thread is for the app.

 

[that girl]

Feel free to bring the discussion to [Concept]EnQRypt Mii.
the apps @Goombi made are pretty close to my concept.

 

[Jiro2]

Well, there's one of the very few advantages of a NNID, personal mii sync

----

Given how you're forced to create one before any other Mii, I wouldn't be too surprised if your personal Mii is just the first one in the file, hmmmm

The problem I am having is that I can't edit my personal Mii because the system thinks I didn't create it (since it was imported from another machine). So I would need to change whatever identifier is in the Mii to match my current machine so that the system will let me edit it.

 

[Nyap]

I'm trying to do this on linux using wine but when I choose my "CFL_DB.dat" it says "Load Error! No Miis Detected!"

edit: also, when I open up the other .exe (fixcrc.exe) it crashes and says:

[Nyap]

I just made a winxp virtual machine and tried running this but the same error appears

 

[Nyap]

Making another mii and then using that CFL_DB.bat seems to have fixed the "Load Error! No Miis Detected!" but when I select to make my personal mii a golden mii, and then I click the "apply and save" button, the program crashes. I think this is because the fixcrc.exe doesn't work.

 

[Nyap]

I'm also having a similar problem with the program throwing an error after saving.

Here's the image of the program opening before I click the save button.

Then, once I click, I see cmd open and close like it's supposed to and the program throws an out of bounds exception.
Here's the image:

Here is the text containing the details of the error:

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I haven't tested the results yet.
I've tested the results. My Mii shows up with Gold Pants. Great.
You should note in your OP that if you want your Gold Pants Mii to be in Mii Plaza you gotta reselect your Mii again.

I tried it on winXP again and I get the same error as this guy but no golden pants when I tested it D:

I tried it on winXP again and I get the same error as this guy but no golden pants when I tested it D:

edit: output from wine in terminal:

You have an entirely different error than mine. My best guess is that your exported Mii file from your 3DS got corrupted in some way.

Here is what I recommend to try and fix:

1. With your 3DS SD already inserted, load Mii Maker on your 3DS. Click on your Mii. Check to see if anything is wrong. (For an extra step make a Mii and then delete it)
2. Exit Mii Maker by going back to the home menu and X-ing it out. Reboot your 3DS
3. Now export your Mii Maker file as OP described.
4. BACK UP THAT SAVE FILE
5. DOUBLE CHECK THAT YOU BACKED IT UP
6. Try the program again.

 

[DrakeLyon]

Anyone having an error with your Primary Mii not being your own anymore, just go to your Nintendo Network ID Settings and edit your avatar. It'll take away the gold pants, but you can simply bring it back later.

This system doesn't have a NNID. I never created one.
