Nick

This article is about the unique nick name of a profile. For the character, see Nick (L4D2).

A nick or user nick is a unique nick name of a profile and its profile id. It is created by the Wii and contains 20 characters.

Some examples for Mario Kart Wii:

A nick can be divided into 3 parts:

1. The first 9 characters represents a 43 bit number printed as a Base32 like string with 32 characters (0-9 and a-v) as alphabet. The number is always the same on a single Wii. The largest possible string is »7vvvvvvvv«.
2. The second part is always RMCJ, the Japanese game id of Mario Kart Wii.
3. The last 7 characters represents a 32 bit number printed as a Base32 like string with 32 characters (0-9 and a-v) as alphabet. The number is different for each profile id. The largest possible string is »3vvvvvv«.

Server gpsp.gs.nintendowifi.net has only one functionality: It translates profile ids into nicks.
