I have a good knowledge in wiis and them being bricked but this is weird.
My friend was hacking Mario Kart Wii like today and he turned off his Wii and then when he loaded it up it would give him a green and purple screen. He has a NTSU U Wii and he uses a Dazzle. He also uses a lot of hacks in Mario kart Wii. Can someone help him? I don't know a lot of what happend. You should probably ask him questions on YouTube his YT is bret36262vr
