Nintendo of Japan's website (Pages 5 through 14) is showing pictures and videos which show some of the features and functionality of the Nintendo Wii. It shows how virtual console games are accessed and their start screens. A photo viewer is also featured, as is the Opera web browser. The virtual console will also use a points system similar to XBLA.
