I read a lot about dolphin not working with 3dripper, but i dont see the problem, just use gl render, play the game to the scene you want to rip, save state, quit, change options to DirectX render, launch 3dripperdx, launch game, load state, rip and enjoy 
.
when i do that way, after launching game in dx mode, game runs about 0.4 fps, but for ripping purposes, thats not a problem.
That works for me with SVN3661, so far only tested GC games and it works, and not only rips geometry, also textures. only checked .obj in blender and textures works perfectly, dont know if same happends with .3ds file.
PS. sorry if my english is not good enought
Update: Also tested with Wii zelda and and rips works as well. Happy Rippings :p
