Savage Empire:

In full screen mode the game does not work. When I alt-enter to the significantly smaller window, everything works fine, but is completely un-playable due to miniature size.

how do i correct this to play it full screen?

What exactly do you mean by that? Does the game do absolutely nothing? Does it start but you can't use the mouse or create a character? We'll need some more information to help.

Maybe changing the graphic mode in the setup might help.

Changing dosbox graphics from surface to ddraw should fix this. I am not sure if it can be done with Graphic mode setup, because I run dosbox games on Linux.

If there is no setting for that, you may modify your dosboxULTIMAx.conf file on game installation directory, and change the output=surface to output=ddraw

On Linux, I use a DosBox frontend to allow me to tweak the settings a bit easier.

I use DBGL

In there I changed the settings under Display to have:

Output is openGL
scaler is set to hardware3x
window resolution 1024x768

This makes for a nice large window on my widescreen display (1080p).

And all of these settings can be tweaked in the dosbox config file.
I would look at :
Program Files/GOG.com/The Savage Empire/dosboxSAVAGE.conf


For me the output config that DBGL creates is: HTH

This did the trick!! Thank you, thank you, thank you!!!

When you are on it, you may get little bit better graphics by changing the line scaler= to some different value. I am using scaler=advinterp3x which gives quite nice graphics.
