It was just that I enabled this Priiloader hack that said Start Wii with a black screen!
I really don't know why I had a hack like that on my list...
I think I must've accidentally enabled it when I was trying to get to save settings (my list is so long that it overlaps it)
I was looking through some Priiloader hacks last night and noticed a couple of them just like that, must be some sort of Kid protection.
Not really doing much Wii stuff these days.
