Doesbox will letterbox most dos games, I believe they are running at a 16:10 resustion. I suggest that Dosemu should do one better and upscale to a 16:10 resulstion by default if available. I can understand if this is not easy(I have not looked at the sourcode).
Not sure what letterbox mean, but try
$_X_aspect_43 = (on)
Letterbox, it means it has black bars at the top and button of the image as a means of peasiving the aspect ratio. I am after the opposite effect of "$_X_aspect_43 = (on)" , when full-screen, I want dosemu to perseve the aspect ratio not stretch too 4:3. Prefable this would be done by deteacting the native resuation of the desktop and either letterboxing the image or if you monitor support 16:9, dispalying the 16:10 image with black bars at the right and left.(pillerboxing)
I wonder why this new stupid SF GUI
doesn't change the "Pending" status
back to "Open" when people reply.
Actually, I am so fed up with this
"new gui", that I'd like to move to
github or anything but SF.
