Super Speed
Catch the robot in each boss level with super speed. Press down on the control button along with the "A" button to make Sonic do the spin dash move. Release the control button and instantly jump with the "A" button. Sonic will then run at ultimate speed. Do not run into the robot, or this will stun Sonic and you will have to do over the move.
Unlock Blaze
You can conquer all three acts of Zone 1 with Sonic the Hedgehog. Save your game and reset the game to see the main menu again. Select the Game Play mode and you will see that the character, Blaze, will be available to play with in the game.
Extra Zone
Play through all the levels and obtain all of the seven Chaos Emeralds before conquering the game. Complete the game with Sonic the Hedgehog and with Blaze to unlock a special Zone and make it available to play.
Chaos Emeralds
Each of the acts has a gimmick with handles that you can grab to enter the portal for the Chaos Emerald. Build up speed using your spin dash move by pressing down on the control button and pressing the "A" or "B" button. Release the control button and let Sonic go. Jump towards the gimmick and grasp the handle bar. Hold down the "X" or "Y" button to enter the portal. You will have a target number of rings displayed on the screen that you must collect inside the portal. Collect the needed rings to obtain the Chaos Emerald.
Defeating the Bosses
Each Zone boss has a pattern to his movements in trying to defeat Sonic. Watch the pattern that the robot boss repeats to maneuver Sonic around him safely. Jump up when the robot boss is low enough to hit the cockpit area with Dr. Robotnik inside. The cockpit area is the only weak spot on most of the boss robots. Hitting the robot anywhere else will cause health damage to Sonic.
