FINAL FANTASY CHRONICLES CHEATS

PS2

In-game reset:
Hold L1 + L2 + R1+ R2 + Start + Select during the game to return to the main menu.
 
Secret Developer's Room (Final Fantasy 4):
The "Secret Developer's Room" is hidden in the Dwarf Castle in the Underworld. Between the weapon and armor shop is an odd section of wall that is actually a doorway to the "Rally-Ho" pub. On the right side of the pub is a fake wall. Go through this wall and you will reach a staircase which leads to the Secret Programmer's Room.
 
Skip Sealed Cave event (Final Fantasy 4):
When you go to the Underworld and go to the Dwarf Kingdom, after you have to fight the dolls in the secret crystal chamber, Rydia returns and helps you fight. After you are done and back in the main chamber, use her warp spell to get back to the crystal room. The crystal will still be there. Approach and examine the crystal to take it. Later when you have to go to the Sealed Cave, if you have the Crystal, you will not have to enter it. You can skip that event and the game will automatically go to the sequence that normally happens as you are coming out.
