Dolphin 3.5 Wind Waker Low FPS

[Shonumi]

I'm fairly sure you can edit your .ini configuration file for this game to use EFB Copies -> Texture instead of RAM. That may provide you with some speed-up. See Garteal's post here: http://forums.dolphin-emu.org/Thread-great-computer-slow-dolphin-with-windwaker?pid=236957#pid236957

Also, check out the Dolphin Wiki or the Wind Waker thread in the Game Disucssion forum for ways of getting around black screens. It's a well known issue for this game, but fortunately a number of solutions exist.
