Nintendo Wi-Fi Connection

Tetris DS Nintendo Wifi Connection
This is primarily a technical document describing the servers that the Nintendo DS connects to to perform Nintendo Wifi. It would appear that at login, Tetris DS reports what it believes to be its rank to Nintendo. This also occurs every time you switch opponents. This process is done via a handshake between the DS and Gamespy. This is also what allows the wonderful device known as action replay to be so nasty to the highscore board.

Web Servers
These servers are used to display the score board: (nintendowifi.com)


 * 192.195.204.176

This is the server to which the DS connects in order to initiate its connection (conntest.nintendowifi.net)


 * 192.195.204.176

Not entirely sure why the DS makes a connection to these yet (nas.nintendowifi.net)

Gamestats server
Metroid and Tetris seem to do this differently, hence this documentation. Metroid makes a connecton to port 29920, whereas Tetris seems to prefer to use HTTP (port 80). More details to come.
