I am sure this has been posted, but I can't find it, so please bear with me. I just d/l'ed the NTSC-U Mario Kart image and when I loaded it, I got a prompt to update my wii firmware. Is this safe to do? Background: WiiKey with 1.9s (Updated yesterday) only NTSC-U games ever played. Haven't done a firmware upgrade in some time. have auto updates off and never played Mario Galaxy or SSBB. I just haven't been keeping up like I should and don't want to brick the console. Any help is appreciated!
