Tales of the Abyss Cheats

When you start a game of Tales Of Dragon Buster at Namco Isle, you can use the original Dragon Buster man character's costume. Doing so will give the minigame retro music and sound effects, too!

In order to unlock the secret shop you must completely fill the collector's book in the game (this requires at least two playthroughs). Upon completion, speak to the man dressed in purple at the library in the Daath church to receive Jade's "Item Collector" title. Speak to the man again with the title equipped and the shop will appear near the Inn in Grand Chokmah.

Unlockable: "Unknown" Difficulty
You must defeat the game once.

Unlockable: Sound Test
Beat the game once.

Abyss Replica Facility

The Abyss Replica Facility is a secret dungeon which can only be unlocked on your second playthrough. To gain access to it, you need to have saved Shiba and completed the Ortion Cavern (East) side quest. Go to Sheridan and talk to the two men in the northwest part of town, then Shiba, and you will be taken to the dungeon.
