Wii: I purchased a rechargable batter docking station. The two batteries are fused together into an insertable battery pack. Problem is, the pack does not appear to fit into the controller in the same way as do the two individual battreries I am using. Doeds any Wii controller use the rechargable battery pack or must I buy a special controller? The wii users guide says nothing about this. I'd try to force the pack into the controller but I am known in my family to tends to break things when I try to fit them together..
