person #2: i don't know can't it mess up your wii?
person #1: the chances are very low and if you didn't update to 4.2 it is almost impossible!! you don't even have to open up your wii which means its still under warranty. the best part is all you need is super smash bros. brawl, an sd card, an internet connection, and a wii (of course)
person #2: wow that sounds great!
