Ok i have both a Wii & a Wii U connected to my TV both have one Wiimote synched to each but only the Wii U has a sensor bar attached...this is my question how is my Wiimote still working on my Wii when the sensor bar is plugged into my Wii U? they both work just fine it just doesn't make sense to me please someone explain this. Obviously it's a good thing i'm just curious as to how this is happening?
