First off, the Game Boy palettes aren’t entirely accurate, due to the Super Game Boy’s limitations, and they are more accurate to the Game Boy store kiosks. Next, this list will be updated when I come up with new ideas for palettes. I will soon upload a video on how to enter these into the Super Game Boy for anybody who doesn’t already know. I have only tested these codes with the Japanese Super Game Boy, so I am not sure if these will work in the North American or PAL versions.
