Homebrew Hacked Mii to QR Code?

[XeonZephos]

Hello, I'm making this thread because i'm curious whether it's possible to make a hacked mii with a custom name into a QR Code so it can then be transferred to other devices?

Making hacked Mii --> QR Code ----> other systems

sorry for bad english

Let me guess, a gold pant Mii? Else you could easily make a QRcode out of it in the Mii Maker app.

Anyway, I'm currently working on that.
1) (PC) Read it: QRcode -> .bin
2) (3DS) Decrypt it: .bin -> .mii
3) (PC) Edit it
4) (3DS) Encrypt it: .mii -> .bin
5) (PC) Write it; .bin -> QRcode

Only step not working is the 3rd one: the 2 last bytes of Mii's QR codes that are (pure guess) a checksum I can't manage to reproduce :/
Once that will be worked out... Time to port APT:Wrap and Unwrap on PC and find the 0x31 keys.
And that will make a nice Mii editor on PC.

With current ways, you can set the gold pant bit with NTR right after the check but before the QRcode generation.

I didn't do that, but if for some reason my method stops working i'll take this into consideration. Thnaks!
