Seems to run reasonably well.
Quote:This video shows off gameplay of Harry Potter and the Prisoner of Azkaban for the Nintendo GameCube using the Dolphin Wii / Gamecube emulator for Windows (version 4.0-1192).
I ended up using this particular version of Dolphin because it was the only version out of the 5-6 that I tried that didn't cause the game to freeze.
Seems to run reasonably well.
