Sonic R

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 GameCube'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.

Accumulate a total of seven hours of game play time in Sonic Gems Collection and
play Vectorman at least once to unlock Vectorman 2.
