Continuing from >>19254592

With Nintendo's servers for the DS & Wii going offline on the 20th (this Tuesday), the DS and Wii homebrew communities have put an effort to create a custom server for patched games to continue using wifi services.
While only Diamond, Pearl, and Battle Revolution are ready for testing right now, it's still advised to register any DS or Wii game that uses friend codes. You MUST have at least 1 fully registered friend to do this. If you don't register your game, you can't use the servers without starting a new game.

>Why do we need to register our games?
So your profile can be saved to the new server. (If your profile isn't saved and you try to connect to it, you'll be given an error because the profile doesn't exist on the server.)

>Why do we need to have a registered friend?
As the link says, it uses your friend code to get your friends' profiles. It can't directly access your own.
