A hard drive for the Wii? Hmm.

Nintendo has filed a Wii hard drive patent protection in US, which allows user to transfer Wii games to a hard drive. Nintendo plans to make a separate hard drive partition for each DVD game, when games are saved on a hard drive, Wii displays a directory and shows all available games with box art. This is done by reading virtual DVD partition on the hard drive.
