WUS is the server which games check to see if your other Wii Friends have the game that you have.
There are two scripts,inquiry andnotify.
inquiry is sent a list of friend codes from the Wii for the server to check. In the same order, it returns a list of 0s and 1s. 0 means the Wii doesn't have the game, and 1 means it does.notify tells the server the Wii has the game.
At this time, this script lacks any connection to MySQL, so a call toinquiry returns a list with every number as 1, and the scripts are very small.
