Lost Kingdoms 2 Cheats

Play as Kendarie Warrior In Vs. Mode
Defeat the Kendarie Card Master Boss (not the lower Kendarie Knights) in the Kendarie Fortress in the first region. Save your game and when you load it again in vs. the Kendarie Warrior becomes available for choosing.

Play as Rashiannu in Vs. Mode
Beat the Royal Tower Upper Level (This final normal stage for single player mode). Then let the game save the completion settings. When you load up that data in vs. mode, Rashiannu will be available in the character roster.

Play as Thalnos from Lost Kingdoms in Vs
After you beat Helena and Leod in the Scared Battle Arena 2 (you can only fight Leod here after you beat the game), go to the northern most door in the area and go in. Fight Thalnos and after you beat him save your game. When you load this data in vs. mode, Thalnos will appear on the character roster.

Play as Urbur Cultist in vs. mode
Defeat one of the cultists that you encounter in battle (most likely, the first one you'll meet is in Ruldo Forest, but any will do), then complete or abort the stage you're on. Save your game and when you load your file in vs. mode, the Urbur Cultist will be available to play (the character is marked as "unknown" on the list).

Duplicate any card
To accomplish this trick, you must have two separate saved games. You can't just save to a different file or memory card. Start a new game, abort the first mission, and save your progress in a separate file.

Now go to the VS mode and load your primary game (the one you want to copy your cards to) for player 1, and your new game for player 2. Wager whatever cards you want to duplicate, then lose to player 2. Load your new game, then save that game in however many slots you want (don't overwrite your primary game!) Go back to VS mode and load your primary game as player 1, and whichever copy of your new game as player 2. Win as player 1, and take back your cards, then go through all the duplicate new games, making wagers of whatever cards you want duplicated. This even works with the very expensive capture card!
