Set LP Damage Dealt: Sets the next instance of LP damage dealt to your choice. Make All Cards Prismatic: A cool, but aesthetic cheat only. An option to enable instant win, setting your opponent's LP to zero, causing you to win right on the next LP check. God Mode, Instant Win: Sets your LP to 10,000. Though I helped this a bit by using subtle amounts. This data translates to your Play Records so it can make you appear suspect to those who can access your stats, (like Konami).
Duel Results (unimaginative name): Sets a bunch of dueling data, affecting duel assessment and giving 8700 points. A cheat table for the single-player, grinding part of the game.
