Every time I try to load the game It runs in a very small window that looks like the attached image, however I would prefer to play the game in fullscreen, or at least a decently sized window.

I attempted a fix I found in another forum post that said to delete the contents of dosboxT2K and replace it with the following text.
[sdl]

fullscreen=true
fulldouble=false
fullresolution=1920x1080
windowresolution=1920x1080
output=Overlay
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal
mapperfile=mapper.txt
usecan codes=true

[render]

frameskip=0
aspect=true
scaler=normal2x

However this fix did nothing except prevent the game from attempting to go fullscreen. I have also attempted to use alt-enter to get the window to display fullscreen to no effect.


EDIT: I resolved this issue by adding a missing bracket
