YouTube user renebarahona recently gave us a taste of what HD Wii would have been like by cranking up the visuals of a few titles to 720p using the Dolphin emulator on PC. We've got two examples, Super Smash Bros. Brawl and Final Fantasy Crystal Chronicles: My Life as a King, posted after the break (be sure to turn on HD mode).
We're not advocating the shameless emularceny of Wii titles, though it is interesting to see how these games look with a bit extra graphical endowment. To use a standard rate of exchange, it's about the visual equivalent of three GameCubes duct-taped together -- maybe even three-and-a-half. We're not quite certain.
