Mod chips are illegal in the USA which im pretty sure you live in. Modding is for nerdy fauilers, it voids your warrenty, it is so cheap and wrong. Mod chips are the reason gaming is dieng, without groups like the esa I would't be the hardcore gamer I am today. Nintendo has attacked piracy twice this week shutting down and finding tons of geeks modding their wiis and DS. Don't mod, its a waste of life. If you can't afford to buy games for a system don't get it.
