Hi, I bought this Wii and its already unlocked but its outdated. Looks like the person who made it, did it on its HD. The one I had before used to have his stuffs on that SD Slot on Wii's front. Now I don't know how to updated it lol Do I need to take its HD out? Or is easier to format it and do it all again using the SD Port? Looks like I need to put it on IOS 250, can anyone help? Thanks!
