Is the Wii edition of the game out of date for speedrunning? Just curious as I notice not a lot of times are on the Wii version.

There's nobody actively playing it, but I wouldn't call it out of date necessarily. Gamecube is the oldest version and many people still play it, so age doesn't really make something out of date but yeah, wii is an inactive version. Even though it's not competitive, it would be a plesent version to run, as it has consistent loads and is very stable

Does the Wii really count as a HD edition of the game? The specs in regard to framerate and resolution are essentially the same as the PS2 and GCN since the Wii can't really do better than 480p

Alright thank you I was getting ready to start practicing using this version so wanted to clarify where the submission would fit.

Wii is the most stable version, very smooth fps, no lags and consistent loads, so you're making a good choice. PC is obviously the fastest / most competitive, but you can get a very solid learning / fun playing on the Wii. I advise purchasing a Wii2hdmi.
