Disgaea: Hour of Darkness Portable

This can be done at any time: Get any character, purchase or get equips/weapons that add HP (Health) and make sure you have a good amound of money. Equip, then un-equip the chosen items, and re-equip them again. After doing so, the selected character will end up with it's original HP and have the MAX HP from the equipment boost. If you can see, there is missing HP. Go to the hospital, pay the person to heal your character, and it will add HP Points into the total. Redo these steps and get your points in the hospital higher and higher. Eventually, the hospital rewards you with an item for the amount of points recieved. (This cheat is able to work with HP, SP and Deaths. HP = HP Equips, SP = SP Equips, Deaths = All-around statted item). When you get your reward, add it or swap it with another HP equip that is lower statted. Eventually, you'll be able to recieve equips that add much needed Health, SP or stats.

Multiple Endings can be achieved by doing one of the following:

Disgaea: Afternoon of Darkness includes the Etna mode, which is basically a twist to the story and features Etna as the main character. Below are several endings that can be unlocked in Etna mode.

There is a hidden mode in Disgaea Portable called Etna mode. Normally you have to get this mode by going through the game and reading Etna's diary every chapter, but you can unlock it instantly by entering the following code during the title screen, with the pointer on "New Game." If you're successful, you'll hear Etna's voice.

In order to open Etna's Room, you must find two secret button's in Laharl's Castle. The first is found behind the Throne and the second is found inside the Skull that is seated on the RosenQueen's Store Counter. Once you have pressed these two buttons, go to the room where Longinus, Ghoss, a prinny, and Gargo hang out. Press X in the corner behind the prinny to uncover the door.

You can fight these three characters in the game however you won't be able to get them, here's how:

Zetta-(Makai Kingdom) Max the 'more stronger enemies' bill then talk to the gate keeper. She will say something about the stellar graveyard that is something powerful is going on there. then head to the promidial soup at the stellar graveyard. Watch the scene, after fight your way through him. His level is actually 9999, but with three level 100 super robo suit and any super weapon, this will be a peice of cake.

Adell-(Disgaea 2) Finish Cave of Ordeal, when you reach demonhall mirror, fight all enemies in there. The enemies will keep on changing and actually stronger. After fighting a sereis of battle, the next time you go in to the demonhall mirror, there will be a scene. It's Adell!! this battle will actually be easy except for the geo symbols, just destroy them with a dimension slash and it will all be easy.

Rozalin-(Disgaea 2) After you fight Adell, go into the demonhall mirror once more, there will be a scene agian. This time you will fight her but with Adell. This battle is of course harder because now they are two of them you will be fighting. Use the same strategy when you fought with Adell.
