The Debug Room is only accessible in the U.S. and Australian versions of Final Fantasy IV Advance. The Debug Room is a small room and the player will need a Gameshark device to access it by entering the following Gameshark codes and loading a save game to enter it:
- 7200E002 000C
- 8200E04E 015D
- 7200E002 000C
- 8200E3C4 0078
- 7200E002 000C
- 8200E3C8 0068
Upon loading, they player will only be able to walk a short distance from the starting tile. Opening and closing the main menu will correct this, and the location window in the main menu calls the Debug Room "Search 349". The Save point in the center of the room is not functional. There are six NPCs with debugging options. Unfortunately they use incorrect text strings, but with the exception of the dancing girl, each NPC only does one thing so this isn't really an issue.
People in the Debug Room
The Dancing Girl controls the player's party and the event flags that are currently set. Choosing YES will set the party and event flags listed in the table, then advance to the next option. The player can choose NO after getting the party and flags they want.
|UP 0||Cecil, Kain||*Gives the player one of each key item from the original game.|
*None of the events in the Mist Cave have taken place.
*Talking to the Elder of Mysidia to access the world map seems to set other events to a later state, preventing the events at Mist from triggering.
|UP 1||Cecil||*Landslide at Mist has occurred.|
*Cecil's sprite will become a dark knight and he'll say "I have to find her a place to rest" upon entering Kaipo, but he does not walk to the inn. The inn map will load after a short period of time, but the rest of the event does not play out. This occurs any time the player steps on the first tile inside Kaipo's walls, effectively trapping the player in the town.

*The tanks are positioned outside the Tower of Babil.
|Square Enix logo||Cecil, Rydia, Kain, Rosa||*Golbez will burn the Tower of Babil's stairs upon entering. For whatever reason, the player must get into a battle before the tower's entrance will work.|

|Sight||Cecil, Rydia, Kain, Rosa, Edge||The Giant of Babil has been defeated.|
Elder of Mysidia
He will teleport the party to the Tower of Prayers. Cecil is always reset to his initial paladin stats after this. Depending on which event flags are set, either the events when the Lunar Whale emerges or when the Cave of Trials opens will play out. From here, the Lunar Whale can be used to travel anywhere on the overworld, which allows for easy testing of various events when paired with the Dancing Girl's options.
The Shopkeeper will set all characters' equipment to whatever their strongest weapon and shield in the original game was: Glass Mask, Adamant Armor, and Crystal Ring. The weapon choices are usually good, but can be a bit odd. Rydia ends up with a Wind Spear in her left hand, for example. Cecil gets the Ragnarok and Crystal Shield regardless of what his current job is. Characters with magic commands will have those filled with all of that command's appropriate spells, even if they normally couldn't learn them.
Golbez will show the ending sequence, starting with the Mysidian Legend displayed in front of the solar system.
Fusoya will start the Giant of Babil event when talked to.
The White Mage will show the ending sequence, starting with the Lunar Whale descending into the sea. No music is played until the telescope scene.
