Legendary Sonichaos (Sonic, Tails, Knuckles and Espio)

Legendary Sonichaos (4.6mb install) is a good solid Sonic game. Play as Sonic, Tails, Knuckles or the new member of the crew, Espio. The usual Sonic gameplay and moves are all here as well as a nice storyline intro at the start of the game to get you going as you try to save the planet from the falling ruins of Death Egg.

Cheats
You will get a cheat code at the credits screen of the game. Each character gives you a different cheat. Type them in title screen.

To beat Robotnik in Angel Island, just keep jumping over the rocks until you are in a small entrance. Some characters have different effect on rocks, some of them can break them.

In Mushroom Hill, you will bounce a bit higher each time you bounce on a mushroom.

Don't rush and try to bounce as high as you can by simple bouncing on them more.
