No Way
no
yes
you erase your game and use action replay to copy it to another game
Yes, it can. It corrupts your saved game, and sometimes when you turn your game back on, it doesn't even go to your last saved game.
If your trying to and Pokemon platinum to your action replay you, can't it will erase the rest of the games you have in it, and that goes for any game you're trying to put in.
Don't use two action replays on one game it will freeze it or if pass it all and then start using it the game will be unfamiliar with the action replay so it will erase the game, or if you cheat to much then it will freeze and there will be a possibility that you my never use you action replay on your game EVER AGAIN.
If you saved in a mystery zone, you're screwed.
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...
you click ok and then you let it earase the last time you saved it
Im afraid if it has ruined your game, you will have to delete your old saved data and start a new game. Sorry
at the top of your action replay game list is a add new game option it tells you the game id of the game insterted in your action replay at the first screen
rigt when you get into action replay its at the botom left
