My stepfather did when we first got the Nintendo way back in 1985 I believe. I don't remember using it much, and remember my stepfather put it in the back of a closet. All I really remember about it is that it really didn't work well. I think it was supposed to work with Gyromite and Wrecking Crew. I'm not sure, but I also think it was supposed to play against you if you didn't have any friends with ya. I remember hearing they took it off the market due to it not working and shorting out alot. If anyone can clarify this, thanks alot.
