And if you want to get really technical then the n64 rf cable IS the nes rf cable with a little dongle to convert that rca jack to the n64's plug. Nintendo has used the original rf adapter from the NES in both the snes and n64. Heck it even says NES on the #### thing.
i ordered an n64 svideo cable directly from nintendo. they sent it to me, i opened it and it said SNES across it. i called back up, saying, well i ordered an64, this one fits, and works but its not really what i orderd, the guy appologized (i got the same customer rep both times, weird.) and said to just keep that one, and hed send me the RIGHT one, that shipping f'ed up. so a week later ANOTHER snes cable. i call and get the same guy AGAIN. (do they only have 1 operator?) and he tranfsers me to his supervisor, she says they are the same cable, and if i could just send back the most recent cable they sent me, it would be appreciated. HAH YEAH RIGHT. sold that sucka on ebay.
