Tated MAME At Last!! But Why Does It Feel So Good??

Getting something closer to real scanlines these days would require you to use at least 8x the resolution in either direction. Anyway getting into this will take a long time and I have to get ready to fly this evening so I'll leave you these two quality links:

This only true when trying to accurately emulate scanlines on an LCD. On a CRT there is natural blending depending upon your monitor color calibration and brightness. The example pic recap shows is of a screen with red overdriven so far you almost can't see the scanlines. So for CRT based monitors, 640x480 with classic or every other line removed is as close as you can get to the real thing.

This.

It depends. If you've hooked the crt up using a vga-scart cable, then yes - pcbs are probably the next step. Otherwise you really should get/make a cable to get the oh-so-lovely scanlines.
Tate is simply better - also for browsing the web actually

I am very intrigued some1 please enlighten me

1280x960 is NOT "320x240 x 4". More like "x16"

It's a scale factor of 4, even though there are 16 times more pixels (area).


The best bet on a LCD right now is to scale the games to native screen resolution (integer scaling ideally) and add some light texture effects (scanlines, etc...) without any filtering.

On a 31kHz CRT (pc monitors) you can use 640x480 but it really wont look anything like a 15kHz screen, will probably look better than a LCD monitor though.



One day hopefully digital resolutions will be so huge (say 3200x2400) that we will be able to simulate the intrinsic qualities of CRTs on these digital screens. (provided we have enough processing power to handle real-time calculations on 8+ Megapixels)

I agree, it's as good as it gets for CRTs and also as close as it gets in general, for now! I'm really thinking of potential solutions that might become better in the future. On the off chance that LCD resolutions increase to levels that nimitz mentioned (and the refresh rates also increase to allow for simulation of the dynamics ... not to mention the increased computational power required by whatever is driving it), there is a chance for simulation to get even closer to "real" scanlines.

With my own monitor and TV settings, I can still notice the difference. The mask diffraction and phosphor diffusion really determine the thickness of the scanlines. Feed enough power into the tube and of course they will merge, but I haven't played around with the settings enough to see it for myself. In that sense, my opinion on this matter isn't as relevant as yours or cools. In a way though, bi-linear filtering et al. is a low pass on an image, destroying the details, while the presence of scanlines is like a hetrodyne modulation, forcing the retina to look at more "edges". This forces more attention to the details and is perhaps why it is pleasing, arguments of "intended viewing conditions", aside. Thus in that case, you don't want to blend the scanlines too much anyway.

Anyway, like I said, it's the best real time (rather than print/screenshot) solution for now, so please excuse my interruption.
