I've got a NTSC US Wii chipped with WASABI ZERO. I have no problem running US backup titles, but I can not get JAP backups run. with a JAP backup inserted, the wii channel screen doesn't respond to wii remote so I have to eject the DVD and manually push the power button to reset. I've always set the configuration "Wii Region Free" - Enabled. I also tried several different JAP backup titles but ended up getting same results. any idea?
