Matt must have slept with Perrin or something, because IGN got their grubby mitts on a Wii debugging unit and a few games, to boot. On the latest IGN Weekly, Matt spends around ten minutes going through the Wii interface (mainly, the options menu) in detail. The menu seems to confirm the existence of one Wii code per system, as opposed to per game, which should make matchmaking at least slightly more convenient. He goes through Sound, Screen, Parental Controls, Sensitivity Options, and pretty much everything you'll see come November 19th. It's worth a watch, so check it out.
