Re: DOSBox ECE (for Windows & Linux)

No, the developer of the patch stopped with development. The latest version is not compatible with the machine=vgaonly setting, unfortunately... I guess a shader (these seem all to be compatible with vgaonly) that does the exact same thing would be my best option...

Re: DOSBox ECE (for Windows & Linux)

the target resolution must be 4:3, and it must have some integer path to get there. Yep, looks to me that's the big difference with the PPP: the PPP does not require the aspect ratio to be exactly 4:3. It will try to get as close as possible to that aspect ratio, but also takes into account the max …

Re: DOSBox ECE (for Windows & Linux)

My monitors full resolution is 1920 x 1080. The sharp shader works fine So just to be clear: the sharp shader is supposed to handle a 320x200 that has to be on a 1920 x 1080 monitor like this: - multiply width by 4 - multiply height by 5 - resulting in sharp 4x5 pixels - resulting in a 1280 x 1000 …

Re: DOSBox ECE (for Windows & Linux)

OK, I downloaded ECE r4391 and used the exact same settings you specified here (except the full resolution, since I don't have a 1200 monitor), but don't get sharp pixels. It also scales to 1280 x 960, not 1280 x 1000. I took a screenshot. (Also enlarged it 4 times to show the result, but you can …

Re: DOSBox ECE (for Windows & Linux)

Because you've also got the scaler set to normal2x. The sharp shader emulates integer scaling, but you're forcing 2x scaling before it even gets to the shader. Also with scaler = none, this is not working. Vgaonly mode is outputting 400 lines (200 lines doubled). That's also what I suspect, but one …

Re: DOSBox ECE (for Windows & Linux)

Opengl doesn't do the trick either. I tried all output modes, actually. I see that the pixels are blurry with opengl, while with openglnb they are razor sharp? This patch actually does perfectly what I'm after: https://github.com/bladeSk/DOSBox-pixel-perfect Only thing is that this patch does not …

Re: DOSBox ECE (for Windows & Linux)

Don't I need a sharp.glsl file then or something? Don't have a shader that's called "sharp". Where do I find it? -- Edit -- Oh, OK, it's a build-in one! Tried it and seems to do the trick, also with VGAONLY! But when looking up close, the resolution is not 1000 but 960 in height (resulting in some …

Re: DOSBox ECE (for Windows & Linux)

Did you try using opengl and the glshader=sharp? I tried glshader=pixel-perfect.glsl and also this gives the correct result when "machine = svga_s3" is used (with wrong color pallette), but once you use "machine = vgaonly" the doublescan seems to kick in, and the game screen does not scale …

Re: DOSBox ECE (for Windows & Linux)

Pixel-perfect isn't going to help you run a game at an abnormal pixel aspect ratio (4:5 is neither 1:1 which is what aspect=false implies, nor is it 5:6 which is what aspect=true would give). You would need a custom shader to map the vertices to a 4:3 screen area. I'm not looking for "aspect ratio …

Re: Pixel Perfect 1280 x 1000 resolution?

as we're on dosbox and lemmings, is there a way to fix the wrong color palette in dosbox? I notice that whenever I see lemmings on dosbox. When you modify the config file to... [dosbox] machine=vgaonly ...you get the correct colors, but then also the doublescan kicks in, and pixel perfect patches …

Re: DOSBox ECE (for Windows & Linux)

640 x 400 would have been considered high resolution at that time, which Lemmings definitely was not. Is "640 x 400" not just an artifact of how DOSBox handles this internally? You are right. It's 320 x 200. But when you use the "machine = vgaonly" parameter it shows as if the "original" resolution …

Re: Pixel Perfect 1280 x 1000 resolution?

How did you activate the log window? How do you mean, exactly ? I just switched to it with the Windows key and took a screenshot (Alt Gr+PrtSc)? 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 …

Re: Pixel Perfect 1280 x 1000 resolution?

You are right about the vgaonly. This indeed seems to have impact on the "original" resolution. If I put it on svga_s3, the original resultion of the playing screen indeed is 320x200, and it scales perfectly, just like the other patch does. (see attachment of the result in ECE with svga_s3 instead …

Re: DOSBox ECE (for Windows & Linux)

Quick question: can I achieve this in Dosbox ECE at this moment: scale a 640 x 400 game to a 1280 x 1000 resolution (resulting in "pixels" that are 2 by 2,5). I want to run Lemmings like this. Original resolution is 640 x 400, but you can see that the game itself already has pixels of 2 x 2 (see …

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, I'd prefer to have a 5x4 pixels with an aspect ratio that's slighlty off, but covering …
