Thanks to Rargh and PeGe's reply.
I finally found out the problem is not the plug-ins - just because my machine is tooooo slow. I tried this game on another machine, and it works fine!
my pc: Celeron 450(oc), TNT2 m64
pc2: PIII 500, TNT2 Pro (this works fine)
But pc2 only the internal spu works. I guess on a faster platform all the stuffs will work.
