Lol, that's a way to fix the issue of having to use batteries.
Yep, a useful hack. XD Now you need to fix the wire problem. I suggest a long extension. XD
I find its optimal usage for holding the controller sideways (Super Paper Mario) or this kind of control method:


You
can use it for other configurations, like for the remote by itself (Wii Sports Resort Bowling) or Nunchuk (Super Mario Galaxy), but yanking cords around could fray them, so I don't recommend it.

Actually the cord looks to be around 6ft. Pretty good if you ask me.
