GB & Gameboy Color Programming (with the GBZ80 CPU)
1 post • Page 1 of 1
We're using our 1 nibble (4 bits) per channel -GRB color definitions... actually the Gameboy Color has 5 bits per channel!
Unfortunately the black and white Gameboy cannot do any real sort of color - it only has 4 shades 0,1,2 and 3 (0=light, because all pixels are off)... I did try to write a converter, but it doesn:t really work well. As the GBC tiles have 4 colors, and there are 4 shades, we'll map each color to a shade - either dark->light or vice versa!
