Hi,
I hope somebody can help me here. Recently I installed DosBox and tried to play Tornado.
The sim loads without problems and I can see the GUI as expected; the problem begins when I commit a mission (simulator, free flight, campaign, whatever) and I see the game as if I were looking a negative image.
Here is a screenshot showing my problem.

I use DOSBox 0.73. My video card is an ATi 4870 with 1024MB.
I tried all the machine=xxx options from vga_only to vesa_oldvbe, all with the same results.
I have read the README and searched in this forum, but couldn't find any solution.
I know the sim runs well because there are videos in Youtube from a german guy who also uses it (that's is how I found about DOSBox); I contacted him to ask about his configuration but he didn't answer me yet, but in a previous mail, he told me that he uses the sim with the default DOSBox options.
