I recently put on my wishlist a GBC Game Shark and a DSi Action Replay. Obvious reason why not stated.
But with all the internet chatter I've come across about how people hate getting hacked Pokemon in trades or going up against someone with All Shiny Legendaries, I have to ask...
Why do YOU cheat?
For me, I only put these devices on there because I know by the time I get the games, I'll be SOL in getting some of the event Pokemon. I like to collect Legendaries. I don't use them, but I like to collect them. (Hmmm, that sounds familiar...) I don't expect to get a 3DS and Black/White before April 10, so I intend to use the AR to obtain a Liberty Pass to unlock that event in the game. Similarly, with the GameShark, I plan to use it to unlock Kurt "giving back" the GS Ball to capture Celebi in the Gen 2 game.
