Secrets
Guadia Quest - "Beat" the game without beating the game.
This trick will let you see the credits of Guadia Quest without having to go through the entire game, thus earning you the medal that recognizes your completion of the game (for Arino's final challenge). First go to the Mausoleum (the path to get to the Mausoleum is located east of Centraan between some mountains and the ocean; you will need to enter the path from north of the mountains). After you go into the Mausoleum, walk nine steps up (you will be in the top left corner). Then press "A" to open the menu and select "Look." You will discover hidden stairs. Talk to the man below and answer all his questions with "yes" and he will show you the credits of Guadia Quest.
