Mii Channel possesses previously hidden connectivity
Wii to DS connectivity has been a largely underwhelming aspect of Nintendo’s two systems, as it has yet to be truly utilized. However, Personal Trainer: Walking, a new title which was recently made available in Japan, will attempt to change that by allowing users to transfer Mii characters between their Wii and DS.
A little unknown (for the most part) gem is DS connectivity that the Mii Channel already supports. By hitting the A, B, 1, and then 2 buttons, the the Wii will look for a nearby DS to connect to. This feature actually has been available on the channel for quite some time, but for some reason or another, has been more or less ignored. By pressing the sequence of buttons, Personal Trainer: Walking will then allow you to transfer Miis from your Wii to a DS. Pretty neat, huh?
