Doubutsu No Mori plugins?

[Little Nemo]

Okay, here's the deal.

I'm completely unequipped to do N64 emulation, but since Animal Crossing is one of my favorite Gamecube games I've owned, I had to try this.

My PC specs hardly enable me to run anything that's not going up and down a scale between 40 and 60 FPS, but anyway....

I have

900 MhZ Intel Celeron Processor
128 MB RAM
Crap built-in video card.

So far I've determined the following

-I can get flawless emulation so long as the graphics are almost completely nonexistant.(some older plugins)
-When using Jabo's 3DFX plugins, for some reason I get a fatal error when using 7. 6 works, but runs at about 1-10 FPS.(PERFECT picture)

Is there anything I can do to be able to run this? I can run Mario 64 and WaveRace 64 at 60 FPS, but that's about it. I didn't think Animal Forest would be such a daunting task for my non-gaming computer, but apparently it is.

Any help would be greatly appreciated.
