This is probably common knowledge now but there is a Wii/Gamecube emulator called Dolphin which allows players to make their games prettier and run at higher resolutions. It’s actually the first emulator that produces quality better than the actual console.

I have heard there are some graphical issues (artifacting) and an impassable bug which crashes the game, but Dolphin sure makes Skyward Sword look nice.
Wow, I mean just look at that! I won’t be able to post too many high-resolution pics, as they’ll kill my bandwidth, but I’ll do at least one direct comparison.
Here is one between Link on Dolphin and Link on the Wii. Man oh man, I wish Nintendo would make a 1080p console already.
