Mario Kart Super Circuit ROM hack adds full 60FPS support

A new ROM hack adds full 60FPS support to the GBA classic Mario Kart: Super Circuit. While the game has always rendered at 60FPS, Nintendo originally updated the track rotation at only 30FPS, causing a mismatch between the sprites, backgrounds, and the Mode-7-style track. This new hack updates the track rotation to 60FPS as well, creating a fully cohesive gameplay experience with no extra performance hit.
