I have somewhat of a similar problem although mine do not screw up like yours al of the time. I usually jusy reset and it all gets back to normal.
One of my maracas is broken, although the other works fine and it seems the base doesnt have a problem with it. I ordered a single marca which should be here in a couple of days, When I recieve it I will be able to clarify whether it is the base or the maraca casuing the trouble. Do you know if I can use the controller extension with the maracas?
Being drunk, stupid and deciding to stumble over the motion sensor on the maracas =P. It could have been that I stepped on it, or that it was surged.. I am not positive, but i think i was just pulling the marcas so i could use the controller for some weasy points on challenge mode
Well, I can attest to the fact that being at least slightly tipsy does add to the fun of this game at a party. Everyone is a little more willing to give it a go after they've had a few beers. But their motor skills have taken a bit of a hit and their control over the maracas can be a little dicey :
