But the game was made with a 16:10 aspect ratio. To compensate there is a black border under and over the game area. Now I do have a 16:10 monitor and it a pity to have four black borders all around the game area. So I was wondering, is there a way to tell dosbox to crop the output video area? I can mess with the source if needed. Thanks Last edited by ezzetabi2 on 2012-3-11 @ 10:21 am; edited 1 time in total

You may also want to limit the mouse range to be inside the viewable region, or you could lose sight of where the pointer is in the cropped-off border area.

Refer http://www.mobygames.com/game/windows/z...creenshots Also, here's a prior post concerned with the black bars in the game... http://vogons.zetafleet.com/viewtopic.p...6397c37420 My guess would be that such was due to the game using a good amount of video and something akin to Quicktime VR (i.e. 360 degree images), and needing to squeeze it down to fit on 3 CDs. It also uses scan-lines in this video. Regarding a means to resize the image, I'd guess that it may be easier to work out a shader to scale things up with one of the DOSBox revisions that have Direct3d/shader support. On this subject, I find the 2xSaLAA, 4xSaL shaders do a good job of cleaning up FMV games that use alternate row scan-lines (though I'm having trouble locating my source for them). Still hoping for a shader that would clean up triple row scanline things (i.e. typically rgb scanlines used to simulate higher bit color ranges with 8b)
