The option to have the 'Stretched, 4:3 Aspect Ratio (CRT-like)' is great but I was wondering if it was possible to add a version which doesn't have the scanlines much like how there are console emulators where it's optional and you can play with a hard pixel look if you wish.
I have set the resolution in some games to where it is a perfect lowering of what modern screens have for their resolution and make it close to the original resolution of the games. So for example because 640 x 480 doesn't scale perfectly with modern displays I set it to 720 x 540 which is still fairly close but is exactly half of 1440 x 1080 or a quarter of 2880 x 2160 meaning I can get a perfect integer scale with the pixels showing as 2 x 2 or 4 x 4 for a single pixel.
However the only way I can do this and have sharp pixels is with the scaling setting mentioned above which then introduces scan lines. I have tried to set the scaling to integer in the nvidia control panel and tested all the different scaling modes in dgVoodoo but none of them have the same effect, it is upscaled and blurred regardless of the setting which is why I think a version of the setting mentioned here without the scanline filter would be the only way to do that.
Similarly would this same thing be possible in cases where there are backgrounds/UI elements that are 640 x 480 and to have those display correctly you'd run the game at 1280 x 960 or 2560 x 1920 making black boxes appear around the picture. At the moment that is only possible with the 'Centered, keep Aspect Ratio' option but it means you have to run it at a higher resolution to have it not be tiny. The only solution to that I can think of would be to have it set where you type in the resolution you want and then set a separate integer scale option to 2x, 3x, 4x depending on your screen resolution which again could have the option for no scanlines or have them be there.
