Can you run this through the PCE-ifier utility that changes pics to 'legal' PCE colors? SNES games are usually very nicely colored (no argument there), but I doubt that this particular pic would lose much in the translation.
<- full noise dithering
<- full pattern dithering
<- 33% diffusion dithering
<- no dithering. Straight conversion
Ignore the dithering on the sprites in the first 3 pics. They convert directly to PCE's palette since all the sprites in DKC are 15 colors. The thing you don't see in that pic, is that the foreground scroll of 'honey' dripping down - is transparent. In motion, it looks a different obviously.
What game is this in English?
Genesis one looks better.
No way. Not that the game looks spectacular, but the PCE as more detail in colors.
