What region should i use on my drivekey to an region changed wii?
I has a Korean firmware version before but i change it to an USA Firmware.
If you region changed it to US then thats what you want to use (NTSC). I'm just curious though... why do you want or why did you buy a modchip if you are Softmoded? Softmod is much better and can do far more than a chip can.
