I currently have a PAL Wii still with the version it came with on launch day and I want to play Super Paper Mario using the WiiKey. If I took my Wii to someone else's house and did the update then played SPM at home would that work or do you need to have the Wii online when you put in the SPM disc? I have heard from some people to have it online but some say it doesn't matter. Which is it? Thanks!
