so @TomF talked me into making it so blending colors on the #Mega68k console is true blending rather than resolving back to one of the 64 palette colors (so that the output is always 64 color)
i made a utility that takes an image and converts it into a tile layer with only 16 base colors with the framebuffer overlaid using all 64 colors with alpha blending and i can't help but wonder if this isn't too powerful
