Castlevania: Lament of Innocence

Clear the game with Leon once and save that game. Start a new game on another slot and enter the name @LLSKILL. Leon will have all his skills when he begins the game.

You can duplicate items early and a very easy way early in the game. First off you must have at least one of the items you want to duplicate. Example would be a High Potion. Now go to the very first save point in the game. Its on Leons right as he enters the castle. Now before you actually go to the save point you really just need to go to the hall where the save point is. If you walk on the left side of the screen on the red part of the carpet you should see a green part of the floor where it looks like the moon is shining through green. You need to stand on the red part of the carpet facing the window on the green spot of the floor. Next press start and go to items. Scroll down to the item you want to duplicate. You should notice that all of your items are going up by one. You can get a max of 9 in normal mode and 5 in Crazy mode doing this. You can do this for any item. Try it with a gem like a diamond then sell the diamonds back to get infinte money.

There's a way to duplicate your items. Enter the castle and head to the door that leads to the Save Room and the room to the other 5 stages. In the hallway near the Save Room, look on the carpet for a green spot of color. Go stand on it, facing the window and open up your subscreen and go to your item list. By scrolling through your item list each item mysteriously increases by one.

There is a second spot inside the Pagoda of Misty Moon where items can be duplicated (again). On the second floor hallway, stand near the second circle design on the carpet (on the map, it will be near the east side of the stage). Press START to enter the item screen and glitch away.

The hallway outside the VI Stone room allows items to be duplicated through the start menu (see Duplicator Glitch #2).
