Re: What work would need to be done to get more accurate vector shaders?

I never said that. I said HDR can improve the mimics of phosphors and that in a way better than regular LCD´s.

Only colored vector CRT´s have a shadowmask, B&W vector CRT´s dont have one. But you are right, there are not much differences. If you know what you are doing, you can convert a B&W CRT into a B&W vector CRT with just little effort.

This method is not new, it is just not supported by MAME yet. Black frame insertion is included in RA, but i think it doesnt work properly.

I am really curious, how your changes will look. It sounds interesting.
