You want higher resolution to Worms United? It's easy. Go to your Worms United folder and find the dosboxWORMS.conf file. Open it with Notepad. Almost immediately you'll find a short explanation and a little further down you'll see the line fullresolution=original. Change 'original' to whatever resolution you want (as the example given; 1024x768 or whatever). Save and then it's done.

I'd also suggest you change the output=overlay line. Replace 'overlay' with opengl. It slightly looks better I think. I even changed the scaler from 'normal2x' to 'advmame2x'. But you do that if you so please. It's not really important.

Thanks dude! That really helped me out as my screen was only half visible. Changed it to native to fit on my screen and it worked!
