Start a Tales Of Dragon Buster mini-game at Namco Isle and press L1 + R1 + Triangle at the title screen. You will have the classic Dragon Buster character's costume, retro music, and retro sound effects.

Unlockable list for Tales Of The Abyss:

On the OverWorld, when you not doing any loading, open the disc tray and remove the game disc. Shut the disc tray. Without the game disc, you can go anywhere on the OverWorld. Once you got to the desired spot, open the disc tray and put game disc back in. Close the disc tray. You can now get Asch on the Albiorl and leave Luke forever in the Mushroom Road. Note: You will lose Luke if you do this.

During game play you will learn of the underworld know as the Qlipoth. However, the trees that hold the over world up are called the Sephiroth.

If you are near a savepoint in the middle of a dungeon, simply save and reload your game for all the monsters inside to respawn. This is useful if you want to farm experience and gold.

Simply go to the earlier dungeons before ending the game and win battles as quickly as you can. This may take some time but it will be worth it if you are planning to play the game again.

Early in the game, in Cheagle Woods and after getting Mieu Fire, talk to the pink cheagle outside the nest. She'll tell you about a flag that brings happiness to the bearer.

Backtrack to the second area of this place and take the northeast entrance. There is a path there that is blocked by vines. Use Mieu fire to burn it, defeat the golem and open the box at the end to get S FLAG. Now you can change the active character that you can see on the screen.
