Sonic CaDa is a hack of Sonic the Hedgehog by CamManS5.
This hack features, new music, new art, secret paths, and multiple end points in each level that offer different rewards. The Special Stages have been changed into Bonus Stages. There will be new Special Stages based on the 2D Special Stages found in Sonic Triple Trouble. Since the new Special Stages are not implemented yet, the Chaos Emeralds cannot be collected at this time without cheating.
