Super Mario Kart: All Stars/Beta Elements

There is some beta elements of Super Mario Kart: All Stars (FunnyIdeaGuy34's Game).
The game was going to be called Mario Kart 64 Deluxe, but it was canned because the developers didn't want it to be an remake of Mario Kart 64 and they had considered naming it Super Mario Kart: All Stars.
Another item, called, the Reverse Mega Mushroom, was planned to be in the game, but it was dropped because of the Question Mystery Mega Mushroom getting adding into the game.
