It's a simple connection really.

There should be an outlet on the back of the 64, that splits off into 3 RCA cords, male cords. One is white or black, red, and yellow. 2 for the audio, and one for the video, that plugs into the back of your television.

The cord shouldn't cost more than $10. I don't know the exact name for it, but I hope this description helps some
