Speaking of NTSC... what are the best default settings for nes_ntsc or snes_ntsc?
Yes, I know some of these questions have already been answered in this thread, but I'm not about to go through every confusing post when all I'm looking for is some very simple answers to some very simple questions. :p
I'm not talking about the color settings and whatnot.. I of course use all the deafults (which seems to be composite).
I'm talking about the other things that have to be applied afterwards, such as scanline doubling method and aperance of scanlines(if any).
- I already interpolate scanlines while doubling, which looks the best. I assume that this gives the closest results to the real thing once some kind of darkening or brightening is applied to render scanlines, but without that it makes it look 'muddy'.
- Should scanlines be visible, and if so, should they brighten or darken the source relatively? If I remember correctly, the demo darkened, and that's where I took my code from and modified it for my own purposes, but brightening instead seems to give a more realistic effect. What does an actual 1980s/1990s TV with an NES connected to it look like with regards to scanlines?
- Field merging... I hate this, not using it causes jitter on computer monitors but also seems to greatly improve the color quality (such as on MM3's Snake Man stage). Is the color quality loss due to a poor algorithm in the filter, or is it better to just display the interlaced video as-is and put up with the jitter ? (It looks better to me, anyway.).
- Host resolution... I run in 640x480 since my emulator is based upon classic fullscreen designs (as opposed to GUI designs where the window is no bigger than the game screen), and the video is stretched to 602x480 or some such by the filter and simply drawn in the middle of the screen... leaving borders at the sides. I'm guessing that this is the correct aspect ratio, but I'd just like to make sure...
- What's the best way to handle top/bottom picture cropping for NES NTSC games? I know some TVs do it and some don't, and they're usually all different.. but what is the most common case? Are the sides ever cropped? What about the distortion that happens as you get closer to the edges of the screen? Does it affect the colors at all?
- Is any of this stuff changed in a newer version or anything? Just to make sure I'm not asking questions about outdated stuff.
I'm asking all of this because it's now the default filter in my emulator and I'd like some reasonably realistic defaults.
