So I have a modded Wii and I use USB loader. I did a softmod using bannerbomb and all that junk, and it works perfectly. My Wii is 4.0U. I haven't really used it in a few months, and I was wondering if I can play New Super Mario Bros Wii without there being any problem? Do I need to update my system, at all? How would I go about doing that if that's the case?
