Do you think it's a major cheat to use an action replay device?
What about people who just use it to get things that you can't normally get like safari balls, or things that are rarely able to get such as event items like the azure flute?
What about people that just use them to get themselves shinnies?
What about people that use it to get rare pokemon that you just can't seem to find anymore, or to clone really rare pokemon?
What if they could do all these things and still come out with pokemon that aren't missing data and won't crash the game?
