if you follow the 4.3 softmod guide, you should be all set
I have Homebrew Installed I used the Smash Stack To Install it
I have DOP-Mii v14.2
but i dont know what to do with it.
As us3rname says, if you follow the guide, then you will answer your own questions. Use the 4.3 guide or the softmod any wii guide.
