My son just got Lego Batman 2, but it is asking to update. We can't seem to buy one game lately that doesn't ask for an update. We bought this Wii in the US, but was living in China and needed it modified in order to play games there. Now we are back and are frustrated! So, I either need to get around the update or change my Wii back. Please help and keep in mind that I don't know all the computer/wii lingo and to speak as if speaking to a child Thanks!
Install Priiloader via the homebrew channel. Doing this will allow you to turn disc updates off. Read this thread.
