Use rgbasm's GameBoy graphics literal for initializing wCreditsFaux2bpp In the 2BPP format, two bytes %ABCDEFGH %abcdefgh define eight pixels %Aa %Bb %Cc %Dd %Ee %Ff %Gg %Hh. Four valid colors: %00 = 0 = white, %01 = 1 = dark, %10 = 2 = light, %11 = 3 = black. Thus `22222222 = pixels %10 %10 %10 %10 %10 %10 %10 %10 = bytes %11111111 %00000000 = $ff00.
