I believe DOSBox simply captures the picture in whatever resolution the game is in. I have a screen capture of Rail Road Tycoon that is 640x400. In another game they are 320x200.

Quest for Glory 4 run in 320x200 which is why the screenshots are using that resolution. If you want to change the resolution of the screens, I suggest you use IrFanView or some other image processing application.

The best program I have found for resizing DOS game screens is Microsoft Picture Viewer, which used to be bundled with Microsoft Office. Almost perfect for integer scaling.

Try VSO Image Resizer (freeware)

So Loom01.bmp a 320x200 screenshot
becomes LoomImageresizer01.bmp which is a 800x500 screenshot.

I wonder if the visual enhancement will show here as well as it looks on my screen, but I tell you it looks good to me

Moderator edit: Replaced hideous large BMP files with PNG files.

I use ACDSee for this. Actually, any decent image viewer / editior should do the trick. Just watch out if you use any filter, because many of them also smooth the image when resizing.

First of all you'll be killed because of uploading huge .bmps 😉
Please replace them with .pngs

and the output resolution is separate to what the game is running in, right? like it's a filter? so if a game runs @ 320x200 and you have dosbox set to output at 640x400... snapshots will still be taken at 320x200.

correct?

correct

😁 my point was explaining that what dosbox outputs at isnt what the game is run at... the larger image is like overlayed yet screen captures ignore this overlay and take a pic of the original.

Unless you use ALT+PRTSC in Windows or some other screencap program. Then you can capture the scaling. Would be cool if DosBox could do this.

The capture in ScummVM is from SDL and uses whatever scaling the game is running with. From the ScummVM Wiki:

"On platforms which use SDL backend (Win32 and *nix included) Alt+S creates a screenshot file called scummvmXXXXX.bmp inside the current directory."

But even though DOSBox uses SDL, this does not work with DOSBox.

Well if you have the lossless original screenshot you can do anything
with it, apply whatever filters to it.

but my fatal point was supposed to be ACDSee or MS Office are no freeware, while Image Resizer is.
