After showing the video to a Gaming Expert on CRT, this was her analysis. ""The effect of the "false" scanline added to the allaying of the screen graphics offers a strange "grid" effect that completely fails the result. In fact, scanlines are not rows added to the video, but free spaces between a horizontal line and the other, that is, they are not additive but should be implemented by "spanning" the horizontal lines rendered by MAME. I talk to you with an eye accustomed to a Sony Trinitron CRT and an arcade monitor.""
