Sure, my wish was meant as an option feature, not as a standard feature. I strongly disagree with you, that this look is "better" then the original look of the Lynx. The graphics looked awesome on the original console and they were programmed to look best with this particular display.
I personally prefer a look close to the original, as an example take a look at newer versions of Stella on Windows, Linux or the Mac. They have a special filter to simulate a CRT Television Set. The results are stunning and the games look much closer to the original. On almost every system, programmers use the limitations of the given hardware to produce certain effects, those effect are sometimes lost in a straight emulation. For me the scanline look of the Lynx is such an effect, which I would like to see back in the emulation, cause it gave the games a very "arcadish" look. Most arcade monitors worked with scanlines too, cause scanlines can be used to give the impression of a higher resolution.
