N64 emulator

For an average pc, you should give 1964 or pj64 a try. Just try out different plugins until you get the best results.

PJ64 and 1964 work well for these games, I recommend you use PJ64 and its default plugins, if you have a slower computer ( <1.2GHz ) use 1964, its is definately worth it. Use Azimers audio plugin .55.1 alpha or .4 beta 2 for 1964, Schibos is good audio, but Azimers just has the quality, only use Schibos if you need to be desparate for speed realted issues.

low end systems (500 mhz and lower): 1964, ultrahle alpha, suprahle, ultrahle 2064, corn and Nemu for some games.
higher end systems: PJ64, 1964, Mupen64 and Nemu.

for your PC, P64 or 1964 i'll cut it. Personally like P64 b/c it has a more "user friendly" interface and has less fiddling required for plugins
