it might if you glitch a new game enough to wreck your game but there is like a 0.1 percent that it will ruin your game
you can, but it might glitch your game.
Action Replay
There is not a glitch that will allow you to get Deoxys. The only way to do it illegitimately would be to use a Game Shark or an Action Replay.
no :(
you must buy an action replay but be careful cause your game can glitch and your game and action replay will not work so use up to 5 cheats every day
You can't unless you cheat with an action replay or figure out the glitch in the game.
Use a codebreaker or action replay
because your action replay is torn up or has a glitch.
it is a glitch
Glitch or Nintendo event
Yes. Use an Action Replay
Not much really happens the only thing is you risk losing your saved file or in rare cases you find a bug or glitch in the game whilst using the Action Replay which could cause your game to corrupt...
