Im starting to learn 70 star, but i realize something that im confused about. Everytime i get to wet dry world, the water level is very high, when in all the run's i watch, the water level is always at ground level. Can someone explain to me why mine is different?

Im curious what would be the best 3rd party N64 controller or the best place to buy an actual n64 contoller. I don't want to continue using an Xbox Controller, and use the official option.
