Tips

2 Lives in Wing Fortress Zone

The lives are at either end of the plane, the first one is after you go up the platforms that go from horizontal to vertical, after going up those, keep going left till you find a conveyor belt going up the tail of the plane, jump onto that, jump onto another one of those horizontal/vertical platforms and knock the life off the tail, as it is too high to jump on to itself, it should be at the bottom of the tail of the plane when you fall.

The second one is after you defeat the machine in the room with the spiked platforms, instead of jumping down the hole and following robotnik, jump across it and keep going right till you can't go further, then jump and press right and you've hit it, then go back and jump down the hole.

Or, if you use debug, go straight up as an object at the beginning of the level and slightly right and place yourself above the life and jump on it, and for the second one you can just skip defeating the machine to get it.

3 lives and a shortcut

In the Chemical plant zone act 1, follow the path until you godown a huge pipe. You'll get shot up and the tube hole will turn into a spring. Grab onto the wall on the right and climb up it. At the top of the tower there will be a life. Fly to the left and there sould be another life. If you keep on flying, you'll reach another tower with another life. Then, jump off the left side and there will be an invincibility and rings.

easier special stages.

If you really want to defeat those frustrating special stages and become the all powerful super sonic, it's best to use sonic on his own instead of both sonic and tails because of tail's tendancy to take alot of rings and then get hit by a bomb causing you to lose valuable rings. It would be alot easier to do the special stages this way.

Easier way to beat final boss

after you beat metal sonic and follow robotnik until he jumps into his machine, go and stand near the left wall. Robotnik will walk towards you and stop, and as he bends down to lift off, hit him above his arms. He will then lift off into the air and home in on you. While he is aiming on you, rev up your spin dash and once he has established his lock, release and roll to the far right of the screen. Wait there while he shoots his arms at you, they will not hit you if you stay at the wall, and when he lifts off, repeat the spin dash manuver. He will again walk towards you and stop, hit him again and repeat the entire process until you defeat him. You can additionally sneak a hit in right after he lifts his machine out from the ground, but make sure you hit him pretty near the apex of your jump, otherwise you'll hit his spike-hands and die.

Getting All Chaos Emeralds Easily Without Cheating

Note, you should set it to "Sonic Alone" so it will be easier to complete the Special Stages. On the first few stages of the game (preferably Emerald Hill Zone 1 & 2 and Chemical Plant Zone 1 & 2) get 50 or more rings and do as many Special Stages as possible. Then purposely get a Game Over and restart (DO NOT TURN OFF THE GAME!). When you get a Game Over, the game will save the amount of Chaos Emeralds you were able to get, which is why it's important to not turn the game off or you will lose your Chaos Emeralds. Repeat this process until you get all the Chaos Emeralds. At this point (if you did this process on earlier stages) you will be able to go through most of the game as Super Sonic.

Green Sonic

How to beat the last level

There are two parts to deathegg zone. The first one is the robot sonic. In order to damage him you have to hit him at an angle when he is just standing there. If you hit him directly on top, you will die. if you are really skilled you can hit when he shoots across the floor standing up. I would suggest trying to hit him twice when he is standing that way you won't have to guess what he is going to do next.
After you beat robot sonic you face doctor robotnic. I won't lie he is very hard and it takes 12 hits for him to die. When he first stands up be close to him. (Not to close) and move slowly away from him as he walks toward you. (don't try to hit him!) When he goes up in the air, you will see a circle form around you. As soon as this happens run to the middle of the screen, press down and super sonic spin. Keep doing that until you see a little red circle around that starts to blink really fast. Then make sonic spin to your left side of the screen. When he lands, his back should be facing you. Be as far away from him as possible. He will most likely shoot two sets of bombs out of his back. When he does this just stay where you are. He will shoot up in the air again. Repeat the step on super sonic spinning while he is in the air. When he lands the second time, his back should be facing toward you. He will only fire one set of bombs and then he will start walking forward. Fallow him but keep your distance. When he stops walking, jump up and hit his back. Be sure to keep away from his fire that comes out of his back at all cost. If you have time you can try to hit him again before he shoots up in the air again. If you are really good you can hit him while he is walking but i would not recommend it. When he shoots up in the air again repeat the sonic spin move but only go to the right of your screen. He should repeat the same steps as before. Here is the order you should super sonic spin at. Go left twice then right twice, then left twice then right twice... if you mess up the order and he lands facing toward you then I think he goes at random. If he ever faces toward when he lands he does one of two things he will either walk toward you or shoot his spikes at you. When he walks toward you just stay where you are. He will not harm you unless you are not at the far side of the screen. If he shoots his spikes at you just jump straight up and dodge each spike. Don't try to hit him. Remain patient when fighting him and don't get greedy on the number of hits.

Play 2 Player Co-Op

Make sure the current character set is Sonic and Tails. Connect 1 more controller into the game system so that you now have 2 controller connected.

Now go to one player, and when you're playing have player 2 move the controller around. Notice how Tails reacts to player 2's commands?

Reset Trick

How would you like to get the emeralds without the debug cheat, but don't want to risk going through the game because of annoying enemies? Then this is the trick for you. (This is not simply blatant advertising) When you have enough chaos emeralds or lost too many times, push reset on your Genesis( configure game options for Sonic only and push A) and go to the options menu. Push A on the character select option and when you reach a special stage, and you'll notice you're on the special stage you left on. Don't go through the option at the main menu that says one player, or you'll start over in terms of special stages.
