The algorithm used to verify the integrity of the database is based on [http://srecord.sourceforge.net/crc16-ccitt.html CRC16-CCITT], though it's an incorrect implementation. It is the same algorithm used to verify [http://wiibrew.org/wiki/Mii_Data#Block_format Mii Data on the Wii].
The algorithm used to verify the integrity of the database is based on CRC-16/XMODEM. It is the same algorithm used to verify [http://wiibrew.org/wiki/Mii_Data#Block_format Mii Data on the Wii].


To obtain the correct value for the checksum, apply the algorithm to the first 0xC81E bytes of the database. This can be done using [https://gbatemp.net/threads/tutorial-give-your-mii-gold-pants-and-use-it-for-streetpass.379146/page-24#post-6569186 FixCRC]; alternativly a pseudocode implementation of the checksum algorithm is given below:

====Special (gold) Miis====
Specialness will override any other color and make the Mii non-editable.
Specialness will override any other pants color.


Copying is rumored to have to be disabled.
A special Mii cannot have sharing on or else it will be deemed invalid.

A red Mii that happens to be the first in the file!
The Mii doesn't really need to be red, it is only red because the personal Mii is always favorited.
