Golden pants for everyone!
What is this?
SpecializeMii is an application for the Nintendo 3DS that allows you to set the special-Status on arbitrary Miis in your MiiMaker database.
Normally reserved only for Miis distributed by Nintendo, a special Mii wears Golden Pants and triggers special events in certain applications, such as Mii Plaza.
How do I use it?
Download the lastest release and then either install the .cia with the CIA manager of your choice or use the .3dsx provided with the Homebrew Launcher.
REMINDER: This software alters data in a Shared Extdata archive. It doesn't really do anything harmful, but to be sure, backup archive 0xf000000b with a save file manager such as JKSM or by holding X when launching the application. The backup will be written to sd:/<current date>_CFL_DB.dat.
How do I build it?
Make sure to recursively clone the repository (git clone --recursive ...) and then build by running make.
