I just installed the new Pokemon Mystery Dungeon - Light for Wiiware which is in Japanese. When I start it up, I get some kind of error and get thrown back to the data management screen. This could be because the first time I ran it, the wii thought I had 0 blocks available. However, I now have over 500 blocks free, so it's either something else or a bug where the game still thinks I don't have enough space. I tried uninstalling and reinstalling already. Maybe someone who speaks Japanese could let us know their experiences with the game.
