Hi guys, I have a backup of Karaoke Revolution (the latest version) and when the disc is in the drive, the game channel shows that it requires a system update. My Wii is modded with a Wiikey 2 chip. Has anyone encountered this before? What update is this? Is it something I can get from Nintendo instead of the disc? I'd really like to avoid bricking my Wii, so any advice is appreciated. Thanks in advance.
