You wrote about potentially dimming the display. Have you considered outlining the characters in a black or dark grey? I've seen other overlays that do this and it does a pretty good job in making the text readable in most lighting conditions.
Exactely, I don't plan to create a completely polished system - just to show how it can be done
The dimming of the text background is very easy. It would be nice to add a black outline to the characters, but that would require another way to blast the pixels or some timing skills
I haven't found any solution, unfortunately.
