yes it can. all action replays and replay codes cam mess up your game ...forever
action replay works by intercepting the game from talking to the system and telling it to listen to it instead of the game. it will do nothing to the game itself, it may however make you console get slower over time and can mess up you files you save while using the action replay.
they sell them at target, for 20$. beware:they mess up your game!

SUCK MY BALLS
Not usally
get a action replay for the ds and the dsi
action replay! other options: Pokemon league! PS: action replays might mess up your game
An Action Replay hacks into a DS game to unlock certain cheat codes from the game. Sometimes, it could mess up the game and corrupt the file or break the Action Replay, and it's around a 85% chance that it will never break {unless you break it with a hammer or something, that doesn't count}
not always the first time but excessive use of cheats will have a 50% tendency to make your game freeze and/or crash on you
it won't work or it will mess up your game boy
If your action replay is not working after you type in a code then the person you got that code from is a bad person with pokesav. He makes codes that mess up your action replay. BEWARE!!!!!!!
