Last night lots of people were getting the error code 20100 for connectivity issues. After searching around it looks like it was on Nintendos end, also people were having problems getting SSBB WFC to work. It appears that it had nothing to do with a chipped console. Referring to some previous posters. The PAL wii channel never worked on my NTSC - u wii either. I was a 9000 rating online and when I switched over to the USA copy it didnt recognize my save file... so I have since started over. Not a big deal since I'm pretty much triple starring all my grand prix races.
see ya on the track.
