Wii U owners in Japan have started to report that they are receiving an unexpected error when they attempt to connect to the Wii U eShop. The error also strikes when trying to update the system firmware. Nintendo says that the problem is caused by a program inside the Wii U which will need to be patched. One of the main concerns is the Dragon Quest X beta went live yesterday and those wishing to participate can’t, as it prevents access by not letting users download the beta. Nintendo has said that it is planning a fix this weekend.
