Re: DOSBox ECE (for Windows & Linux)

It's an Nvidia card. Here's the option in the control panel. Without actually measuring, it looks correct to my eyes when running Lemmings in DOSBox with the black bars on both the top/bottom and sides in fullscreen mode. Again, fullscreen=original must be set. Thanks. I am familiar with the Nvidia …

Re: DOSBox ECE (for Windows & Linux)

Another option (assuming your video card supports it) is to temporarily turn on integer scaling in your video card's control panel (Has a large impact on performance to keep it on all the time). Then keep DOSBox set up with opengl, the fullscreen=original, and no scaler or glshader. I'm not aware …

Re: DOSBox ECE (for Windows & Linux)

I guess a shader (these seem all to be compatible with vgaonly) that does the exact same thing would be my best option... I would just use the sharp shader at 1440x1080. It only does interpolation on the edges of the pixels. With something like Lemmings with the large areas of contiguous color, it …

Re: DOSBox ECE (for Windows & Linux)

Maybe there's a scaler out there for DosBox ECE or SVN that does exactly this? You can always go back to the newest version of ECE with the PPP. You'll have to go back through this thread and it's mentioned here when it happens. As for SVN, I think you can just add the patch? Not sure if it's still …

Re: DOSBox ECE (for Windows & Linux)

No, the scaling amounts for each axis are independent. So upscaled 5x horizontally and 6x vertically using integer scaling (to 1600x1200), then the bilinear filtering stage does nothing because it's already at the target resolution. Ok, great. That's what I originally thought was going on. I …

Re: DOSBox ECE (for Windows & Linux)

Even shader=none (with output=opengl) will use integer scaling if the output size is an exact multiple of the input size, since filtering gets disabled for that case. Okay. That explains why I never ran into the issue (being that I have a 4:3 resolution). So, from what you're saying, I'm getting …

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)

I guess the sharp shader also tries to keep the EXACT 4:3 aspect ratio, and does not scale to a resolution that's not 4:3? So 1600 x 1200 is OK, but 1280 x 1000 not? The sharp shader works fine, and a lot of people use it so I think it's something with you setup. First of all, exactly what are you …

Re: DOSBox ECE (for Windows & Linux)

Someone suggested there I should also ask the question here in the DosBox ECE thread. This isn't an ECE specific question. The sharp shader works perfectly for me. Basically, you are telling it to scale 320x200 to 1280x1000. Sharp does this by integer scaling 320x4 and 200x5. In my config for ECE …

Re: DOSBox ECE (for Windows & Linux)

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 nice 4x5 pixels, and some square 4x4 pixels). So close, but no cigar :-(. You have to force the output resolution to 1000. …

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 …

_Rob wrote on 2020-12-23, 21:48: DBGL works fine as a graphical front-end with DOSBox ECE. That looks really good. It's basically what I'm looking for, except that it requires Java. I don't have any Java stuff anymore, not sure if I would install it again just for this.

Re: DOSBox ECE (for Windows & Linux)

What's wrong with having 2 DOSBox configs? I've always found this to be a PITA myself. There are enough different possible combinations of settings for different games that it makes more sense to have one for each than it does to group games into similar configs and launch from the command line. …

Re: DOSBox ECE (for Windows & Linux)

Also, the text at the bottom of the page seems incomplete: "If you like DOSBox ECE and would like to support further development, feel free to" It seems text has been cut off at the end? On my browser, there is a donation button after that text. You may be using a more efficient ad blocker than me. …

Re: Emulating MT-32 on an RPi2

in MT-32 General
Well I was able to get everything working by downgrading to the last version of Raspbian Stretch! Was not working on the latest Buster version. Is this a known issue that I just overlooked? Not with Munt in-general. I have Munt running on Buster from around July or so, after they upgraded to USB …

in MT-32 General
Well I went through and did everything manually. Installed the latest Raspbian OS and then installed munt. Everything went smoothly except I can not see the Roland UM-One USB MIDI device inside of munt. There is just a blank window when I choose New Midi port. Is there something special I am …

Re: DOSBox ECE (for Windows & Linux)

SLI is messing things up with DOSBox. That doesn't surprise me. Nvidia seems to be downplaying SLI. It's only going to be available on the 3090 in the new generation, so who knows what's going to happen to driver support. And let's face it, driver support for multi-gpu setups has never been that …

I have been trying to use the Pi3 image from this thread on my Pi3b+ and a Roland UM-One cable. After writing this image to a sd card and booting it up it just hangs at a grey desktop screen after logging in with username "pi" and password "raspberry". Am I supposed to do anything to the image …
