i have wii key 1 firmware 1.9s
That's the latest version.
wii firmare 3.2U
4.2 is the latest firmware but is not needed to play all games.Lookup Dop Ios Mod v9 it can update all your ios files
so you can play the latest games.It will require a network connection on your wii in order to use it.If you do not have
network connection available then get NUSD and download the latest ios files of each version and install them with
wad manager.DO NOT GET ANY STUB VERSIONS THOUGH.
and i have homebrew channel but probably an old version
You probably still have the HAXX version.Get the latest hackmii installer from hackmii.com and run it to install the latest HBC.
and nothing else
i have no idea if i need loader or anything
Only need a loader if your going to use an external usb hard drive.You wiikey will play burnt games so you don't need a loader for that.
