So I have a mod chip on a US Wii and I just got a Japanese SSBB. Apparently, it doesn't work because after the update it says Invalid system detected or something like that. I have to bet it's the update but at least all my other games still work. (I also have the dual news and weather channels). But I gotta ask, is it also the fact that I'm using a US Wii and not a Japan Wii that's causing the problem? Plus, if I buy an original US retail SSBB, will it work on my US modded Wii? The mod version and mod chip names are confusing, especially since I don't know which I have! PLS HELP!!! P.S., An original retail US version of Super Mario Galaxy definitely works!
