@_@ Don't have one. Don't want one. I'm against them. =\ But... that's probably only because I don't have one. (Although if I *did* have one, I probably wouldn't use it for fear of messing up everything I'd worked for ._.) My brother's friend has that... Action Replay thing, or whatever it's called, and my brother used it on his game to max out his Pokemon and also to get limitless items. So, since he's got an unfair advantage, I refuse to battle or trade with him. @_@;;
o.o; But... I wouldn't wanna risk using them anyway. I've heard the rumours. >_>'
