I've read some stories online about users wii's getting bricked. I'm not exactly sure what all this means.. but for the main part, they aren't able to use their wii anymore, and need to buy a new one when this happens? a lot of wii users got their wii bricked when trying to play a backup of paper mario.. how safe really is the a modded wii.. with the wiikey? ..I guess if you play it safe, and make sure somebody else tests it out first.. and follow their instructions you'd be safe. for example.. ppl have posted saying to do a wii update before trying to play a backup of paper mario and it worked fine.
