Heh, I thought I remembered something about having to use the higher bits of the colour, but I figured that was for converting to RGB.  But then I never really worked with SNES either; Gameboy Colour just also happens to use 15-bit RGB.  |

I don't understand that equation, but I just figured out that the palette editor will show it. |

First off, it is the other way around, in other words, the blue colour component is the highest one.
Second, you have to act a little bit different if you want to convert a 24-bit RGB colour to SNES.
S = ((R & 248) >> 3) ^ ((G & 248) << 2) ^ ((R & 248) << 7).
This one should be right. |

A few weeks ago, I was finally un-lasy enough to write a few functions that converts SNES colors to PC and vice versa. Maybe I should make a program out of them and release it? |

Is there a way to convert PC RGB values to SNES RGB values? |
