those games were made to be played fullscreen, so play them fullscreen

Fullscreen looks awful on a TFT, when the image gets interpolated...

You can try switching your desktop resolution to 640x512

robertmo, that would do exactly 0 to help the fact that the image would still be interpolated.

Screen has 1280x1024 pixels.
Image has only 640x400 pixels.
In order to stretch the 640x400 pixel image to 1280x1024 pixels, one needs to interpolate.

If your LCD is 1280x1024 this means:
1280x1024 looks perfectly and
640x512 (1280/2x1024/2) looks perfectly too.
All the other resolutions would be ugly

so you can play dosbox (in a 640x480 or in a 640x400 window) on 640x512 desktop with same effect as with playing dosbox with imaginary scaler=normal4x on 1280x1024 desktop

I have just found out even better way.
It should be possible to run it fullscreen.

After you have added 640x512 resolution in your windows drivers (so you can switch your desktop to 640x512) you will be able to run dosbox (CVS) fullscreen with this resolution.

Just modify your dosbox.conf this way:
fullfixed=true
fullwidth=640
fullheight=512

Hey, yes that sounds cool.

Well initially I thought the same as Snover - changing desktop resolution must give interpolated blurry display - but changing to half width and half height still means interpolation but in a power of two, every pixel gets doubled in both dimensions and must therefore be as sharp as desired.

I'll give it a try and tell you about it.

(In the meantime I had been starting to implement it by myself, but it slowed down things significantly and would have been some hard work.)

Hi Robertmo,

fullfixed, fullwidth and fullheight are actually features, that are only implemented in CVS, couldn't tested though, because compilation seems to be broken with Visual C 6.

Already compiled windows versions are here:
Help with Chronomaster Visuals
and here:
CVS Builds (once a week)

Even if it doesn't help you can still try running dosbox in a window mode as I suggested before 😀

Hi,
well I've finally managed to persuade Windows to switch to 640x512.
Yes, it's working, but I get a light blurryness, so it's not really nice.

That's going to happen because it's interpolating to fill up 1280x1024 pixels with 640x512 pixels. That's how LCDs do it.

Snover, it's cool to be justified, isn't it?

It doesnt work correct 😒 (0.61)

My Desktop is 1280x1024
when I set fullscreen in

640
480

than there is a black line on the top...

when I set fullscreen more than 480, the screen resises to the half and centers in the middle 😒

If you don't want to have that black line swich to 640x400

under 480 it is too high and the first line is missing 🙁
