Sonic the Hedgehog Published by: SEGA Developed by: Sonic Team Genre: Platformer Number of Players: 1 Release Date: US: June 23, 1991 Japan: July 26, 1991 Europe: June 23, 1991

Story: "Dr. Ivo Robotnik, the mad scientist, is snatching innocent animals and turning them into evil robots! Only one tough dude can put an end to the demented scientist's fiendish scheme. It's Sonic, the real cool hedgehog with the spiked haircut and power sneakers that give him super speed.

Help Sonic fight hordes of metal maniacs and do the loop with the Super Sonic Spin Attack. Speed down twisting tunnels and swing over dangerous booby traps. Leap across lava pits and dodge burning rocks. Then splash through the chilling waters in an underground cavern. And if you're lucky, you can warp to the secret zone where you spin around in a floating maze! Your greatest challenge lurks in a secret lab where you come face to face with Dr. Robotnik himself!

Spin through space, loop 'til you're dizzy, save the animals and become the super hero. Be Sonic! Be atomic!"


Confuse Sonic
Did you ever wonder what Sonic would look like if he was possessed? Find out by holding A+B+C, while the demo is playing. (To access the demo mode, just start the game and let the title screen fade out)

Slow Motion
Think the game is gypping you? Play father time and slow time down by pressing Up, C, Down, C, Left, C, Right, C, and then press start. Now when you pause the game you can use the A button to restart the game, the B button to slow the game down, and the C button to advance the game frame by frame.

Debug Mode
You first must enable the “Slow Motion” mode before this cheat can work. After you’ve entered the “Slow Motion” code, pause the game and then hold the A button down until you see Sonic. Once you see Sonic press Start, while still holding the A button down. If you did this correctly you will now see a bunch of hex numbers where the score once was.

To start or stop debugging press the B button, to scroll through the sprites available press the A button, and finally to place a desired sprite on the screen, press the C button.

Level Select
To enable level select mode, press Up, Down, Left, Right, and then hold the A button and press Start during the title screen.

Get Emeralds
Don’t want to bother maintaining at least 50 rings to get into the special zones? Enable the “Level Select” mode and select the Special Zone. Once you grab the first Chaos Emerald, and entered Green Hill Zone Act 1 reset the game and enter the level select code once again. This time when you select Special Zone, you will be taken to another zone to get a different chaos emerald. Repeat this process until you have all 6 Chaos Emeralds.

Control the Ending Sequence
You must first have “Debug Mode” enabled, then at the end of the game when Sonic starts running with all the animals jumping everywhere, press the B button twice. You now have regained control over Sonic and can do as you please. However, you can die if you walk off the screen from where you first came from. What happens next is your screen will turn white and will stay that way until you restart the game. Now if you head all the way back to where Sonic does his ending pose, then you lose control once again.

Here are the set times for the Time Bonus.

Easy Lives
When you’re playing Green Hill Zone Act 3 head straight, crashing through the wall, then through a tunnel, and passing spikes and botniks until you see a yellow spring. Jump over and land in the empty space between the spikes and the yellow spring. Now walk all the way to the left until Sonic is pushing the spring and then turn around and jump over the set of spikes. After the death defying jump behind the waterfall grab the 50 rings and the extra life. Now jump up on to the yellow spring after the waterfall and backtrack a little and jump on the winging platform above the spinning spiky bridge. Keep going left when you make the jump across the other set of platforms take the lower route and jump off to the left and land on top of the “loop-de-loop.” Here comes the tricky part, go kill yourself somewhere, I like prefer the spinning spiky bridge. Repeat until you are satisfied with torturing Sonic.

Marble Zone Shortcut
After you make it past the area where the lava shoots you up, head over the two chandeliers with spikes and jump into the top part of the wall, this will take you to an extra life, and another secret tunnel on the right side of the wall. Use caution when exiting the tunnel because there is another chandelier with spikes right as you exit.

Scrap Brain Shortcut
At the beginning of final Scrap Brain level hit the release button to the platform, and run right off the platform. Continue down hill pass until you reach the water. After you press the button release go through the top part of the water route and head up out of the water. Now when you reach the top jump over the large water gap on to the other side, once you’ve made it across head right and fall into the water. Now continue right until you see stairs going up, when you reach the top you will be at the end of the level in record time.
