I'm not certain, but I *think* that one of the blurry screenshots you posted of Mario Galaxy (from the introductory watch-the-castle-get-kidnapped sequence) is actually pre-rendered video and not rendered by the game engine in real time. If that is so, then it's probably limited to whatever resolution it was in the original game, and not available in the high-resolutions possible when your PC video card is doing the rendering.
Also, I that blurry background for Mario Sunshine is the way it was in the original game (I think it's supposed to be heat-shimmer to make things look like a hot tropical environment). It just stands out a lot more when you're running the game at much-higher resolutions than it was designed for. I'd think it would be possible for the Dolphin developers to add a feature that makes that effect optional, but I don't think it's been implemented yet.
Looks like you're trying to run Mario Sunshine with the widescreen hack? If you run it in 4:3, you don't get the "ghosting" of characters. And I think that the widescreen hack exaggerates the heat shimmer effect too.
