Recently I have the same problem with my Wii, the fps drop and the same thing happens to me on the mario kart channel as in the video that the guy uploaded, what do you recommend I do? I am buying the triwing screwdriver to clean the console
The same thing happens to me too, there are fps drops in some parts, it doesn't only happen to me in lego games, in no more heroes and others too. It's not normal and I still don't know how to fix it
