New Super Mario Bros. Wii looks sharp, but slow, when run on the Dolphin emulator, a piece of software that has offered a similar high-definition look at Super Mario Galaxy and Super Smash Bros. Brawl.
While the YouTube HD video runs at a snail's pace, the creator of the above video says the Wii game ran at a smooth 60 frames per second on his rig and copy of Dolphin. Place blame on video capture tool Fraps, which makes for a Mario as slow as molasses and the occasional audio-visual glitch.
Wii HD theories may be nothing more than that, but if Nintendo engineers are considering some sort of higher-definition option for future iterations of the console, we super hope it's backwards compatible with at least this particular game.
