Can you delete all the games off an action replay without messing it up?

it can....but it shouldn't if it does turn your game off and then back on.....

the percentage is:

99.99%-----------------------------------------------------00.01%

not delete delete

But let me assure you it won't....

I know from experience....

me and my friends used one and it deleted none of our games!

I'd get a new one off of play.com or ebay!
