Use the AV connections that come with the N64 if at all possible. Sure, if you are going to be toting your N64 around with you, they are a nice thing to have, but they give less quality, and greater headaches than the simple connections that come with the system. I used to take my N64 to friends' houses all the time, and for a while all I had was the RF adaptor (the AV was lost for a long time), and I was getting very tired of screwing it in and out, and to and from this and that... it was just a real pain.But the worst part of it all is that you cannot hook up the sound to your stereo if you choose to do so (as I do)!
