blamtnt: Yeah. Both resolutions are the equivalent of my monitor, fullscreen and double are false, output is surface, etc. etc. But like i said, changing something changes nothing. So i really don't know what to do.
output=surface will prevent many other switches from working. For example, there are settings for scaling, but the "surface" output method can't scale, so they won't have any effect. Not sure if that's the problem in your case because I can't tell what you changed exactly, but it could be.
Try setting the output method to "ddraw", or at least "overlay".
What exactly are you trying to do? From looking at the screen, perhaps the game was using 320x200 resolution, and your monitor's aspect ratio is probably not 16:10?
