A: It is one out of the 2 versions that can both Rev-Roll into the machines in the Inky and Pinky fights, and doesn't lock Pac-Man on the world map for 3 seconds after a boss.
A: Mainly for emulation inaccuracies, particularly loading times and framerate.
Q: Are USB/ISO loaders allowed (i.e Nintendont)?
A: Yes, ISO loaders in general are considered emulation, thus runs can still be submitted until the categories threshold.
Q: Does Wii load faster than GameCube?
A: It's been chalked up to being no significant difference or if there is it's extremely minimal that it doesn't matter, though it has yet to be tested more in-depth.
