i Agree with that if somebody hacks and there game crashes its there fault. only bad thing is if hackers put hacked mons on the gts and it gets to somebody elses game. theres a problem there because there file may corrupt and they dont hackeWell like Justin said, AR is sold in stores. It could even be considered illegal for Nintendo to ruin games because of a hack, but I think I the GTS should either not allow hacks at all or have some kind of label that says that it's a hack, and maybe even a filter option that asks if you don't want to find hacks in your search results, which is exactly what Justin said, but with that it's a matter of the hacker's honesty, though. The only way for the GTS to ensure that hacks aren't being labelled as legit is for it to have a filter that labels the Pokemon automatically, otherwise you still have people that would lie about hacking. And actually, I believe AR has a warning on the back of the package that says it can corrupt save files and is not approved by Nintendo, right? I think it says something like that... I'm positive it warns you that it can ruin your save file though. I know it ruined my Diamond game once (which is why I no longer hack). Theoretically, if Nintendo were to make the games more sensitive to hacks (since they allow a lot of extra data right now) then it would technically be the hacker's fault, because AR even warns about ruining games. In all reality... A hacker can do a lot that a legitimate trainer can't do. A hacker can put 255 EVs into every stat, give every Attack a certain amount of PP that's ridiculously high, and even give them 1,000 for every stat. The games allow for that extra data, only gameplay prevents it from occurring. If Game Freak were to remove the room for this extra data, which may be their system for stopping hacks if this is true, then a hack can completely ruin a game and it would be the hacker's fault for doing something illegitimately. This wouldn't prevent hacking entirely though, but it would prevent overpowered hack monsters with impossible attacks from being in the games, which is still good enough I guess.
