@Felthry any% is 0x now due to a bug in the Wii Virtual Console's emulation - but it's still an official Nintendo release, so it counts
@Dex I thought there were other A presses that couldn't be removed on VC?
@Felthry Actually, after checking, I got this the wrong way round:
The original method for accessing the Secret Aquarium was fine on VC, but would crash the N64 version because the N64 crashes if the camera travels to a parallel universe, and you can't lock the camera in one position while you're in the castle like you can in the levels.
However, then they found a way of getting to it without parallel universes so it's doable on both.
@Felthry The Secret Aquarium would be skippable anyway if needed - the any% route gets 95 stars, and you only need 70 to beat the game.
