Hello, I have US Wii U console but I wanted to use Japanese firmware so I bought JP Wii U console but I only have US gamepad. The US console has haxachi+mocha+rednand so I can access sysconfig but it does not give me a permission to change DRC0 language on the gamepad. I researched about how to switch gamepad region but I could not find clear answer. Is there any way to do it except using drc-sim? I will look forward to see good news. Thank you.
