Dosbox in a scaled fullscreen

I have a laptop with a modern nVidia graphics card in it, and I want to run dosbox in fullscreen, having the games scale to the 1680x1050 display I have.  I've been tinkering with ~/.dosboxrc (a configuration I created), and can't get it just right I suppose.  When I Alt+Enter, the app goes in fullscreen, but it's centered, not scaled.  What settings so I need to set in .dosboxrc to do this?

Re: Dosbox in a scaled fullscreen

You can try changing aspect and scaler settings in the render section  of dosbox.conf , but i doubt this will result in what you want.


Another approach is to add modes like 1024x768,800x600, 640x480 , 320x240 & 320x200 in your xorg.conf .

In the sdl section of dosbox.conf use this :

fullscreen=true
fullresolution=original

When you start dosbox it will attempt to choose the screenmode from the ones listed in xorg.conf that is closest to the original mode.
The scaling will be done by your videocard/monitor this way

Sidenotes :

- low res games look a lot better in a window than full screen on modern hardware

- Test which modes are supported by your videocard / monitor
  The 320x200 and 320x240 are often not supported by modern hardware.


- Dos games were written for CRTs. If you happen to have a working 14" or 15" inch CRT lying around use that as external monitor for your laptop.


Multi-init booting with apg Openrc and systemd coexisting
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

Re: Dosbox in a scaled fullscreen

I think that some outputs will scale and others won't. Using

[sdl]
fullresolution=1280x800
windowresolution=original
output=opengl
...

[render]
aspect=true
scaler=normal2x
...

works for me.

EDIT: Personally, I like the look of blurry scaling better than tiny crisp windows for my DOS games.
