So I figured out how to go into windowed mode, but I cannot for the life of me alter the window size. I just want to make it a tad bigger so I can more easily see it.

Anyone have any suggestions on how to do this?

In the CONF file or GOG's setup program, try different scalers like normalX3 or normalX2.

Go into dosbox_por.conf in wordpad etc. and find the line that says windowresolution=__whatever___ , I think it is windowresolution=original by default and change "original" to the desired window resolution with no spaces.

For example, a 800 x 600 window would be "windowresolution=800x600"

Save and exit. Test. Game on. Etc. :)
