Sonic Mega Collection Plus Cheats

Have a Sonic Heroes completed game save file on your Xbox hard drive. When you start the Sonic Mega Collection Plus game up, you will have Comix Zone and The Ooze unlocked from the start!!

To unlock the Hints text for each game, keep it open for three hours. You don't have to play the game, just let it run. After three hours, exit out, and when you reenter the game, or check the Hints menu in the Options area, that game's hints will be available.

Play Mean Bean Machine at least 30 times to unlock Flicky. You can just enter the game and exit as soon as it loads up. After the 30th time, exit to the title screen and enter the games menu again.

Play Sonic the Hedgehog and Sonic 3D Blast 20 times each, exit to the title screen and then go back into the game select screen and Blue Sphere will now be unlocked.

Extra Stage:
To play stage 14 in Sonic 3 and Knuckles, play through the game with Sonic and collect all of the chaos emeralds. When you get to the Death Egg Zone (stage 13), you'll have to fight Dr. Robotnik in what appears to be the last battle when he's in a giant robot. However, if you have all of the chaos emeralds, the fight will continue as Sonic changes into Super Sonic. The game mechanics are changed for this short stage, but it brings the final conclusion to the Sonic series. (This code also works for Sonic and Knuckles without Sonic 3, except the stage numbers will be different).

Alternate Endings:
Beat Sonic and Knuckles with Sonic, you'll get 1 ending, beat it with Knuckles, you'll get another. Play Sonic 3 and Knuckles and beat it with Tails, you'll get another. Beat the game using Sonic with all chaos emeralds, you'll get another ending; same when you beat the game with Knuckles with all chaos emeralds. Beat Sonic 3 and Knuckles with Sonic with all of the super endings, you'll get a slightly altered ending to the ending while beating the game with all the chaos emeralds; same with knuckles with all of the super emeralds.

Play and exit all non-gamegear games 50 times each, exit to the title screen and then go back into the game select screen and Comix Zone will now be unlocked.
