|Things to keep in mind
:: These images are presented to illustrate the relative differences in quality between the various video connection types. Viewing these web pages via super-high-resolution computer monitors does not provide an accurate representation of how these games look in-motion, in-person, on dedicated 27"+ TV sets that were designed and optimized for the various connection types (ex: S-Video pictures looks better on a SD CRT (looks crisp) made in the mid-90s than a HD LCD TV (looks blurry) made in 2006; coaxial pictures look better in real-life than in the screenshots since we regain some detail while the video noise is in motion; etc.).
:: All S-Video screenshots will appear slightly more saturated (rosier) than the Component Video screenshots. This is the result of the color settings on my old capture hardware (S-Video), which I adjusted to yield more vibrant colors than the default settings years ago. My newer capture hardware (D-Terminal/Component) continues to run on its default settings.
:: All Component Video screenshots will not look as good as the pure RGB frame grabs from other games seen on the internet (still looks better than a lot of the stuff Nintendo shared over the years). My screenshots have been subjected to several stages of quality loss, illustrated in this flow chart.
:: If you're not familiar with the techie vocabulary used in this article, ask Google or Wikipedia, or google "wikipedia".
:: This is not a "Wii vs. GameCube" article. If it was, the article title would say so.
:: I DO NOT guarantee all this is 100% accurate. I only researched as much as laziness permitted. This article is just my opinion, afterall.
