Dunno if it was just a bad burn but this isn't working for me on Wiikey, US console. Boots up ok, Konami screen, Wiimote held sideways screen (happens to be in English for some reason..), and then a black screen. Tapping a button turns the screen white. The home button still works and I can exit the game.
That is not normal if you can exit , a non working game always freeze the console , so like you said it is a bad burn or simply a bad release wich can also be possible .
Keep us inform if you have more news . Really hope that beauty will work .
Between Mooyah have you also tried that jigsaw puzzle and puyo puyo , those are the 2 games left i dont know either if they works on ntsc u wii or not . Thanks a lot for all the infos you already gave for ntsc u users .
