The swift12 test built for the Wii behaves differently than the PC version when it comes to specular lighting: it looks like it adds a 50% of extra white light over the geometry. This can be easily seen when disabling all lights but the specular one: on the PC version, all unlit areas are pitch black, whereas on the Wii the whole teapot is at least grey in the unlit areas too.
