Everything has already being said.
On a software console emulator, to get it full speed on a decent PC, you have to make compromises. The nature of these compromises determines the emulator's accuracy. It could be bad but fast (zsnes), balanced (dolphin), good but somewhat slow (higan, still not perfect), or perfect but slow as hell (PONG transistor).
tl;dr : There won't be a GameCube 100% accurate emulator anytime soon.
