Since it's zelda, you can use UHLE. But, if you have a fast pc (550mhz-1GHz) you can use 1964 or pj64 (1964 is much faster due to schibo & rice's leet dynarec core

)

Now, you'll need the rom which we can not provide. Alot of times you can find them on IRC, but i can't say where exactly, as this is copyrighted material and use of it in rom form is illegal.
If your 3d accel is not a geforce or a radeon, you should use glide64+evoodoo.

http://www.evoodoo.emulation64.com (evoodoo)
Now, if you're going to use glide64+evoodoo, you should put evoodoo in your system directory (e.g. for Xp, 2k, C:/windows/system32. For 98, 95, C:/windows/System)
Once it's all setup, go to start>run>econtrol. Configure it
without fast alternate Zbuffer. It can cause some clipping issues.
If your hardware is a geforce/radeon, then you're fine. Just use the plugins supplied (you'll need to download pj64 1.5 to get the plugins, even if you're going to use 1964) But keep in mind jabo's Dsound 1.5 will not work with 1964. Good luck.
