dolphin freezing at certain points

[Lttman]

The game is Zoids: Full Metal Crash (GC)(JAP) on dolphin RC1.
My settings are:
   
   
   

For the most part, the game is fine. The problem is that when you are in story mode and have to fight an Iron Kong, the game almost always freezes when you defeat it (usually on or during the explosion like on the picture)
   
(other fights sometimes cause it to freeze in the same spot, but usually if I do the fight again, it doesn't freeze).

I am using OpenGL because some of the screens in story mode don't work and freezes the game when I use the directx one.

Any Suggestions?

(the dolphin.exe doesn't freeze up, I meant the game just seems to freeze and not doing anything at 0 fps)

EDIT: btw, it does occasionally let me through to the next battle as the screen-shot is the 3rd one I've fought. It usually takes many times before it will let me through though
