Hey Dude I have just read your other threads. Are you trying to kill your Wii ??? Read read read the softmod any wii guide follow it then check problematic games. You may be too late. No there is no MASTER reset to my knowledge. If you mean a Magic button bad luck. Wait for an answer before you totally kill it. I'm sure you had boot 2 and a Nand backup ???????
is there some sort of Master reset at all?????
