The Raiden comparison is yet another very interesting comparison because of the color differences between the two systems. I tempted to say that the more drab and washed out colors of the SNES version are more fitting here (one noticeable thing to point out is the street in the fifth screenshot, where light off shades of pink and green are used in the PCE version instead). Sometimes the vibrantness of the PCE versions looks cooler though, like the eigth and ninth screenshots.
You mean as opposed to the
paler pink and green used in the SNES version.
That's one aspect I agree with, although I'm guessing that the colors look better on real hardware (similar pale shades were available on PCE, it makes no sense for them to use
neon shades).
To me pretty much all the PCE shots look better, vibrancy aside just because of the general coloring. The SNES version was colored like a poorly done Genesis game, where much of the detail and objects disappear within similar shades of the same color. Like the crashed ship at the top right corner of the second shot and the tank stuff Nat mentioned. The 8th SNES screen could be a Gameboy screen shot run through a Super Gameboy.
Even the shot you mentioned still looks better on PCE because 90% of the screen of the SNES version is grayish green/greenish gray. From the screen shots given, it looks like the entire SNES version is colored with strictly greyish shades of pale green and brown with grays inbetween(even the water). The red player ship actually stands out in every shot as being pretty much the only thing not gray, green or brown other than tiny highlights on random objects.
Now I'm curious to see how the arcade was colored. I'm also guessing that the Genesis version
has to look better overall than the SNES version, unless it's a terrible port.
