Re: Pixel Perfect 1280 x 1000 resolution?

TomVDJ wrote on 2021-01-14, 18:06: Last commit was on July 9, 2019. No idea if he is still working on it, but I'll give it a try... Thank you for contributing to the community. If one man solves it, everybody else can use his solution. I myself will look into it after I finish my current work on a …

Re: Pixel Perfect 1280 x 1000 resolution?

In the meanwhile I also tried the dosbox version from here: https://github.com/bladeSk/DOSBox-pixel-perfect and I was able to get what I wanted (see other attachment "Pixel Perfect Patch") but only this does not work with "vgaonly". Only works with svga_s3, which results in some colors being off, …

Re: Pixel Perfect 1280 x 1000 resolution?

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.

Re: Pixel Perfect 1280 x 1000 resolution?

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 …

Re: Pixel Perfect 1280 x 1000 resolution?

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= …

Re: Pixel Perfect 1280 x 1000 resolution?

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.

Re: Pixel Perfect 1280 x 1000 resolution?

Ah, damn, yeah, I tried with different output values there, none of them seemed to work. Also not openglpp. Could you just let me know what settings SHOULD work for the [sdl] and [render] section of the config file? Not until tomorrow evening. In the mean time, post screnshots of DOSBox ECE and its …

Re: Pixel Perfect 1280 x 1000 resolution?

Oh man, I don't seem to manage. I think I missed some parameter in my config. I now got a small screen with artefacts around it. In attachment my lemmings.conf file (I start it with a bat file that calls dosbox ece with this config file). I've put machine=vgaonly (instead of svga_s3) since this …

Re: Pixel Perfect 1280 x 1000 resolution?

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 ( …

Re: VIDEO Patch for pixel-perfect scaling (SDL1)

Just a note, I've ported the Pixellate shader to DOSBox SVN, it can be found here: https://github.com/tyrells/dosbox-svn-shaders . Some screenshots of the shader in action can be seen in the following forum post: https://www.vogons.org/viewtopic.php?p=835314 . I see no screenshots in that post. Did …

Re: DOSBox ECE (for Windows & Linux)

Honestly, ECEs future doesn't look to bright atm... Maybe it's time to quit and leave the stage to more capable people, who know better what they're doing (I'm looking at DOSBox-X or dosbox-staging). I concur with the recommendation about dosbox-staging , which already contains opus and the pixel- …

Re: VIDEO Patch for pixel-perfect scaling (SDL1)

Interesting post about Pixellate shader (i know its not possible in Dosbox right now, maybe only in Retroarch core?), what do you think about it? https://www.resetera.com/threads/how-do-you-like-to-display-your-retro-pixel-art-games-filtered-or-unfiltered.90135/#post-16387673 Looks good to me, if a …

Re: VIDEO Patch for pixel-perfect scaling (SDL1)

I've tested various combinations of outputs & scalers, each with aspect corretion on & off. That is a lot of tests. I don't have time to study and comment on them all. For each test I've captured a screenshot of my whole screen, in order to let you evaluate also the content of dosbox's console …

Re: DOSBox ECE (for Windows & Linux)

The tearing issue only occurs when machine is set to vesa_nolfb . If I use vesa_nolfb it tears even when I use the internal DOSBox video recording. It doesn't matter if V-Sync is enabled or not. Does it tear only with the outputs introduced my patch, or with other outputs too? If I enable V-Sync ( …

Re: New forum suggestions/Feedback

in Milliways
I agree about the wasted vertical space. Possible solutions are: remove the greeting line and the two empty lines around it; place the greeting line and banner on the same line: I like this, except that the width of the display is unknowable, so it’s not possible to reliably position anything to …
