I've looked about but couldn't see anything like this. I have two nunchucks and one of them just doesnt seem to register movement and/or orientation like it should. They both function equally in Zelda, both capable of spin attacks and shield shoves but in Wii Sports Boxing, the fault nunchuck is incredibly sluggish by comparison. Worse yet, in Metroid the grapple beam function is entirely impossible with that nunchuck. Anyone know anything like that? Is it broken?
