The Last Ninja 3, a Commodore 64 title, was pulled from the Virtual Console. The title, which was put online back in late 2008, apparently didn’t get a proper emulation on the Wii. This created a bug that would make the game unplayable beyond the first stage.
Originally a patch for the title was planned, but the patch never saw the light of day.
Whether or not The Last Ninja 3 will ever be placed back online with proper emulation is unknown, but for now Nintendo is refunding Wii points to consumers who have purchased the title.
Thanks Masamune for confirmation!
