A Nintendo insider said: “A chipped Wii might sound cool but it is useless. The latest Wii extravaganza, seeing Mario back in a racer at the front of the pack, Mario Kart Wii, would be useless on a chipped Wii. You’ll never get the interaction or support when it all unravels. You’d have to be pretty stupid to think online gaming won’t be easily log-able in such digital days! Chip it and you brick it, as we say around the office. There is only one real Wii experience – and it doesn’t come chipped!”
Where does it say "Chipping disable on-line play." The only thing I can guess at is that they are saying pirates won't get the wheel (interaction) and that they won't get support for using a pirate copy. Not interesting.
