Kirby's Dream Land 2 is one of a few games that have custom palettes built into the GBC bios.Remember when I said that it's not a good idea to play monochromatic Game Boy games on a Game Boy Color? Well, look at this screenshot from Kirby's Dream Land 2.
The colors are, without any shadow of doubt, really horrible.
The Gambatte emulator should be able to run it in properly in GBC mode using the bios palettes. Or you can run the game on actual hardware in a way that the GBC sees the Kirby header when the game starts.
This was the only screenshot I was able to find and most people seem to screenshot it in SGB mode.
