Simple question really: How can I get the game to run in Windowed Mode, preferably 1024x768? I havent messed with DosBox settings much so I am honestly not sure how to pull it off.

In the game directory, find the file called dosboxBAK.conf (assuming you are talking about Betrayal at Krondor, it will be a different name for Betrayal in Antara). Make a backup of the file, then open the original in Notepad or another text editor. Find the line reading "fullscreen=true" and change it to read "fullscreen=false". That will make the game start in windowed mode. Then find the line reading "windowresolution=original" and change it to read "windowresolution=1024x768". That will resize the window to the 1024x768 resolution. Remember to save the file after making the changes. Now when you run the game from the shortcut or start menu, it should run in the appropriately sized window.

By the way, you can press ALT+ENTER at any time to switch between windowed mode and fullscreen. I found that Betrayal at Krondor stretched to fill my widescreen monitor when running at fullscreen... turns out this is because it runs at 320x200, which is not actually a 4:3 resolution but it used to be displayed in 4:3 aspect ratio, with non-square pixels. So the art is actually designed around non-square pixels in a 4:3 aspect ratio. To fix it I just found the line that said "aspect=false" in dosboxBAK.conf and changed it to "aspect=true". This causes DOSBox to force the 320x200 resolution to run in 4:3, so it now displays properly when fullscreen on my widescreen monitor, with black bars on the sides. Just in case you wanted to use fullscreen at some point.

Post back if you have any trouble getting it to work.
