The Nintendo 64 3D Converter is originally going to be an accesory that plugs into the controller or connect the N64 and Virtual Boy (as a link cable) and the infamous Virtual Boy console and allows the N64 to transfer data with Virtual Boy, original games that downloaded into the Virtual Boy, or the Virtual Boy can be a separate controller and 3D glasses. It was originally going to be released at the same time the Nintendo 64 was released but it was cancelled due to Virtual Boy's failure.
