Unlock full versions of game demos
Once you have unlocked all the playable ending demos, use the following trick to unlock their full game counterparts. Go to Sonic The Hedgehog (either version), Sonic 2, Sonic 3, Sonic 3D Blast, Sonic Spinball, Robotnik's Mean Bean Machine, or Sonic Chaos. Keep intentionally killing Sonic until you are out of lives. The game will end, then restart at its own title screen. From there, you can start at level 1 of the game and play until the timer reaches zero.
Unlocking Museum bonuses
To unlock most of the pictures in the Museum, just start each of the main games five or ten times. Then, play each one for a few hours. Just leave the game idling; you do not have to be actually playing for that amount of time.
To unlock the playable endings, three movie trailers, and the last picture in the museum faster, change the day portion of the PlayStation 2's system date. For example, change August 25, 2005 to August 26, 2005. Then, start the game. Once you go to the museum you will have more playable endings and/or movie trailers unlocked. Repeat this process until you have all three movie trailers and sixteen playable endings in the museum. This will also get you closer to unlocking the final illustration.
Unlocking Museum games
Play Sonic Gems Collection once every day and accumulate over 24 hours of game play time. Then, start the game 30 to 70 times to unlock the different end Bosses to many classic Sonic games that you can play.
Vectorman
Have a saved game file from Sonic Heroes or Sonic Mega Collection Plus on your memory card to unlock Vectorman. Alternately, accumulate a total of five hours of game play time in Sonic Gems Collection.
Vectorman 2: Display map coordinates

Vectorman 2: Transform
Pause the game and press Circle, Square, Left(2), Down, Square, Down repeatedly until the sound of the orb weapon stops. Press Start to resume the game as a Fire Ant. Repeat this code to transform into a Shield Bug. Note: Playing the bonus rounds as a Shield Bug will result in invincibility.
