Sonic Mega Collection Plus Cheats
The core Megadrive titles are without a doubt the highlight of this package. Sonic 1, 2, 3, and Sonic & Knuckles all hold up well a decade on, and are still a blast to play.
The compilation also includes various games, features and unlockable content. It includes all the original game manuals, and covers of Sonic comics throughout the years, along with a small collection of pictures and movies from Sonic Heroes.
Unlocking hidden games:
You must accumulate 30 hours of game time for each game. Once the game save window reads 30:00:00 or above, games will begin to unlock. The game will accumulate hours, even if it is just running the title screen. When you need to exit out of the game, make sure to save the game before exiting.
Press R3(for ps2)(Right Analog-stick for xbox) to remove the black border around the games.
Select any game and start it. Allow it to idle while the game is actually running. After a certain amount of time is accumulated, you will unlock the in-game hints for that particular game.
