In general it is up to the game or program to support that resolution, either for this particular chipset or as a VESA-compatible mode.

Understood. But in this case I'm dealing with an application that doesn't set the screen resolution. So I'm wondering if there's some way to tweak that via DOSBox.

For applications the same.

What exactly do you want to do? If you want to run your application in full screen, there are ways to do that. DOSBox will automatically upscale the application's resolution to whatever the resolution of your screen is, using one of various popular upscaling resolutions. But a DOS application written to address a 640x480 resolution will never be able to address a higher resolution, no matter what DOSBox tells it.

I'm running Wordstar 6 for DOS. When I run it in the default window, the font size is a bit too small for comfort. But when I go to full screen the font is too large and blurry. What I'd like is to roughly double the size of the default window. Any thoughts?

I'm using the default "machine=svga_s3" in the DOSBox configuration file. Would changing that have to something else (what else?) have any effect?

Thanks.

DOSBox is really aimed at Games!

A different machine type won't help much. What you want to change is how the DOSBox screen is presented to your real OS, outside the emulation - not the resolution of the emulated environment intself.

So what you need is to use a scaler (and probably set it to 'forced', since we're talking about a text mode app)... check the conf file for info.

Ah ha! Thanks. Futzing with the scaler configuration option solved my problem. Turns out that "scaler=2x forced" does just what I want.
