What game did you get to boot on this 3.2kor? I am trying, but have not gotten anything to load here yet. If you load an iso with the Korean key in wiicrubber, it will open and show you the files or it will open and show you bad. Bad mean the iso is not using the korean key. You can do anything to an iso with wit, but it is more complicated, I don't know how atm.
I am ending the worlds shortage of coasters, trying to get something to load. Would help to know what mk iso you got to boot.
