Castlevania: Portrait of Ruin Cheats

Hard Mode Unlockables
Depending on which Level Cap is used, defeating Hard Mode will yield different bonuses: non-sellable and non-usable "trophies" and permanent stat boosts. Defeating Hard Mode with a lower cap will automatically net items from the higher level caps. For example, defeating Hard Mode with Level 1 cap will give you all 3 sets of bonuses.

Konami Man and +50 Strength: Defeat Hard Mode with Level 1 Cap.
Twin Bee and +50 Intelligence: Defeat Hard Mode with Level 25 Cap.
Vic Viper and +50 Luck: Defeat Hard Mode with Level 50 Cap.

The dark side of Vincent
If you take Charlotte as your main character and press UP for about 10 seconds in front of Vincent, the shopkeeper, he'll make a funny comment. Try with and without Jonathan on the screen!

Luck Bonus
To get a permanent luck bonus for both your characters, beat the last boss in Hard Mode.

Duplicate Quest Reward
Upon completing a Quest, Talk to Wind to open up the quest menu. Press A twice. When you hear the "reward" chime, press START to exit the quest menu. The quest reward is already given to you, however, the quest is uncleared from the list. You can repeat this as many times as you want and get the rewards again.

Jump a few more extra times
This glitch will make your characters be able to jump twice as much as you currently can. For example, if you don't have the double-jump relic, you are able to jump twice with this glitch and if you have it, you are able to jump up to four times. This glitch is useful for sequence breaking and getting items early in the game.

1) First have both characters on the same screen
2) Tap the touch screen above to make your partner jump up to two times (depending if you have the double jump ability or not)
3) Once your partner is high enough, press X to switch characters
4) If timed correctly, you will be able to do an extra jump or two right after switching characters

Use "Grand Cross" Subweapon with Maria
When playing as Richter and Maria once you gain a few levels and have enough MP you can use Richter's "Grand Cross" subweapon and deal massive damage (especially to enemies who are weak to 'Holy'-based attacks). The only problem is you can't move while performing it... with Richter.

Have Richter select the "Grand Cross" subweapon then swith over to Maria with "X" without having Richter out with her. Press "R" to have Richter come out and cast "Grand Cross". The moment he appears (he doesn't even have to have casted it yet) immediately press "A" to send Richter away and the "Grand Cross" will go to Maria except she can move around with it! This works well on bosses since you can pummel them with the cross but still be able to move out of harms way.

Play as OLD AXE ARMOR
Kill 1000 (or more) Old Axe Armor (Monster No. 92). Then SAVE. You need to SAVE in order for the Kill Count to register. Now when you start a New game. You can choose OLD AXE ARMOR as a player character once you've received the Good Ending.
