I LOVE this game because it's easy-to-use controls. The speacial stages are easiest. To enter the speacial stage you have to gain 50 or more rings and hit a star post and jump to the star circle above the star post. Now you are in the speacial stage. To win the emeralds you have to gain the number of rings that is told if not the stage ends. To get super tails , use the debug mode.
