Yes, I have found a emulator that might work for you... if you have one hell of a computer. You need a PII-266 or better, 64MB of RAM (approx.), a 4MB Video Card, and a 6MB or better Graphics accelerator. The emulator is called "N64 Ultimate." The address for the emulator is
http://members.xoom.com/n64ultimate. But that is just the emulator. Zelda 64 is another problem altogether. I don't think it is findable right now. Give it another month or so. The game as a ROM will be about a 22 or 23 Megabyte file when you do find it. You're best bet would probably look for it on FTP sites. Not many people have 20 Megs of free internet space to use on one game. Oh well, good luck.
