How does this relate to craft and quality?

I have put seven pixels per byte to match the original Apple ][; the Apple uses that extra bit to shift the color signal slightly; by moving from half a pixel, you change from the “pink and green” artifact colors to the “blue and orange”. That doesn’t do anything for us; I mean, it moves things slightly, which might be useful when our resolution is so low, but what about something else?。新收录的资料是该领域的重要参考
