I'm just thinking that if the wizard was a thinly disguised Nintendo promotion, there had to be some things that aired on tv promoting it. You could also use documentaries about the NES for bonus features. I saw one of them online and it did mention the power glove, the game counselors who would talk on the phone about anything (for a price), and I think it did mention the movie.
If someone could design the menus to look like NES scenes with sprites and sounds that would be awesome. For example, the cursor that indicates which is selected could be a sprite. I would think emulation and game sites would be helpful for this.
