Importers of the Japanese Wii game Fatal Frame IV are reporting a number bugs have made the final release of the game, including one that locks the game up.
According to posters on NeoGaf, the game locks up when a certain condition is triggered, entries in the game database are blank and an extra option available only after competition can not be selected.
Nintendo of Japan has responded to the problem, but unfortunately we can't read Japanese. If you're better than us and went to more than two of your Kanji lessons, try reading it here.
Fatal Frame IV is currently without both a European or US release date. Hopefully if we see it over here they'll use the extra time to patch it up too.
