it didnt brooke anything lol if you are using vwii sigpatcher for overclock and dont have a wiivc to overclock with files you will always get blackscreen doesnt matter if its nintendont or a normal wii game, only use the overclock sigpatcher if you need it and to launch titles with the c2w.img ,dont run by default.I mean it doesn't matter I will use an older version lol I think the c2w NINTENDONT implementation is what broke things.
Why to implement it anyway? There is NO use for that.
so your logic is latest nintendont doesnt work for you its nintendont fault? when it works for everyone else? that doesnt make much logic just check your files, redownload nintendont boot.dol and make sure its named boot.dol and not loader.dol.
