Welcome to the cheats for Disgaea: Hour of Darkness for the PlayStation 2. Below are the cheats.
Etna's diary
There are two hidden switches in the castle. One is behind the throne, and another is near the skull on the counter of the Rosenqueen shops. Flip both of them to allow access to Etna's diary, which is in the middle corner of the intermediate hallway between the throne room and the shops. If you visit this area consistently for each chapter, you will be rewarded with a Testament item in the final chapter.
Get the most out of your turn
If you are trying to level all of your characters mainly by using team attacks, etc., move all your characters into position for a team attack. As long as none of them besides the initial attacker have not performed any actions, after the team attack you can move them back to their original locations and move them again. Repeat this as desired. This also works if your characters are just out of a healers range; you can move them, heal them, then move them back into battle.
Easy experience
In stage 5, level 3 (Terrible Cold), there is only one Geopanel that does not have the invincibility attribute. Combine all the enemies by throwing them into each other, making one high level enemy. Throw the enemy onto the Geopanel that is green. Trap him/her on the Geopanel without invincibility by surrounding him with your characters. Since all of your characters are on invincible panels you cannot be defeated, yet you can wear down the high-level enemy who is trapped on the non-invincible panel. This is a great way to jump 10 levels at once early in the game.
