Yeah, i meant your pixel perfect shader in previous post 😋 Both your screenshots are truly pixel-perfect, with 2x2 square pixels and no apsect-ratio correction. The original resolutions are 640x400 for the first and 640x480 for the second screenshot. The first one has PAR of 1.2 (5:6) and should …

The source looks good. Have you sample screenshots online demostrating the pixel-perfect upscaling of 5:6 PAR DOS games and programs (text-modes are a good test of pixel-perfect)?

Is it possible to achieve the same result with pixel shaders? (there is one that i used, ported from https://tanalin.com/en/articles/integer-scaling/ ) Hardly possible without some preparatory calculations on the CPU to find the best PAR approximation in terms of aspect-ratio error and usage of the …

I used your build few years ago because at the time I liked to have pixel perfect patch but I'm in DOSBox Staging camp now. They have burned pixel-perfect mode at the stake, replacing it with blurry vertical-only and horisontal-only interger scaling modes, so that the Staging project has no output …

Thanks for your enormous effort of maintaining ECE through the years. As the first unofficial built to include my pixel-perfect patch , ECE helped make it available to more conneseurs of low-res pixel-art aesthetics, who were not satisfied with the blurry interpolation of the standard output modes.

Hello, all I remember playing an old strategy game for MS-DOS where one of the achievements/advances/discoveries in the research tree was—Logistics. I thought it was Civilization until I checked it. What game could it be? P.S.: It is the right sub-forum for my question?

Solo761, What about my question apart from Sound Blaster and DOS? I can find a T610 easily, whereas procuring a T5710 will be harder. As to CPU speed, have you tried any of the various throttling utilities, e.g. throttle?

Only works with svga_s3, which results in some colors being off, …

How did you activate the log window? Well, I don't think I shall be able to fix this old and unsupported patch in an old and unsupported version of DOSBox ECE, but I may try to do so in some active fork. I will also try to find a way to turn off doublescan.

Yep, the version before that works fine (R4296). For space quest it does exactly what I want. For Lemmings however it gives me this result: A screen of 960 x 800 with 4x3 pixels. While the aspect ratio is perfect, The ratio is 3:4 (width:height), and it is far from perfect, because it yields an …

To be clear: I used the Dosbox ECE version r4301 I found here: https://dosboxece.yesterplay.net/ in the archive folder, since I read here on Vogons it was the last version supporting Pixel Perfect. Maybe that statement was not correct? (Found it here: https://www.vogons.org/viewtopic.php?f=32&t= …

Thanks for the screenshots. Your DOSBox ECE does not seem to work correctly in pixel-perfect mode. I will test it on my side. I also asked you to post a screenshot of its log output window. Can you do that?

BardBun, the problem is not the centering of the image, but the scaling algorithm. I don't think you can always achieve correct integer scaling in full-screen by changing fullresolution. LCD displays must always work at their native resolution for a sharp image.

I rediscovered "Lemmings" and would like to play it pixel perfect with DosBox. The original resolution of Lemmings is 320 x 200. With aspect correction to 640 x 480 it means that 20% is added to the height. What I'd like to get, is pixels of 4 x 5. Ideal aspect correction would be not 4x5 but 5x6 ( …
