No.... N64 run on either 240p or 480i depending on the game, let me also add that most all the N64 games are 240p and won't play on most newer TVs and is only properly viewable on SDTV CRT's. 480i is full reselution SDTV signal and is viewable on any SDTV and HDTV. I ran into this problem when I was trying to circuit-bend my sega genisis which runs on 240p and had to stick a digital pass through between the TV and sega. Digital pass throughs (DPT) are fairly easy to obtain for low cost. Radioshack sells a DPT called a RF Modulator and I believe it goes for 35-50. That will fix your problem with the N64's resolution.
