it's safe to assume any F-Zero that gets a VC release gets the same rules as the games that are already in it.
so basically, same FZSNES Wii U VC rules for MV, GPL and Climax (Climax is out in JP Wii U VC)
(it sucks when there's no one around to update rules tho...)
i went and updated the rules with Wii U VC info. check it to see if everything is fine.
