Hidden audio
While the game was in development, the game programmers wanted to implement speech. However in the final version, the speech was not included. The speech was only in the battle system. Use the following steps to hear the voices that they were going to use. Turn on the Dreamcast with no disc. When the system screen shows up, go to CD player. You will see there is no CD when you go in the CD player. While at the screen with the CD Player controls, insert either game disc. When the disc is loaded in the CD player, the Skies of Arcadia CD will appear. Select "Play" to hear the hidden audio.
