If the player uses the original Sonic the Hedgehog or Sonic Compilation, a screen with Sonic, Tails, Knuckles and Robotnik stating "No Way" repeatedly is displayed. By pressing the A, B and C buttons together, players can access a minigame based on the Special Stages of Sonic 3 and Sonic & Knuckles. Players can enter a twelve digit code on this screen, with every number combination generating a different variation of a Special Stage level. This game is retroactively known as Blue Sphere in Sonic Mega Collection.
