hook up my nintendo 64?

The yellow cable is the video cable, so you have only actually have one audio cable. You can definitely play the N64 on it, but you may have some audio issues since you'll only get one audio cable in there. You can always buy an extra cable that connects to the red input and allows you to plug both audio cables into it. Otherwise, it should work fine.

Have you actually tried hooking the N64 up to you're T.V. Because that would answer you're question. If the red and yellow mean the same as white and yellow (white being picture and yellow being audio) then it should work just fine. If it doesn't get an RF cable. An RF cable is a cable you hook up to your T.V. through you're cable connection, and if the T.V. doesn't have cable then I don't know what to do.

properly there are 2 issues that u can do a million. u can get a vcr with a cable that links ur vcr to ur television then plug contained in the av cables into the vcr 2. get a sparkling television it truly is all i am going to assert
