A mysterious Famicom board found!

Well I went to the thrift store and found this board of a Famicom game. I'm wondering what it is but I won't be able to figure it out tomorrow since I'm just too lazy to plug the Famicom right now. har har har! Anyways, I'll take photos and show them here so lets hope it's something interesting. I hope it sure is! Cya later!

I wonder what it is!
