The game is fresh, the Dolphin SVN build used to record the video too and the Full HD resolution is a luxury no Wii physical machine could afford, something made possible just thanks to the magic of emulation and (of course) the PC platform superior power.

The videos are pretty nice, its a shame Nintendo let HD slide this generation.
