@Alexpop2: It is just at the location TSHyper had found: 0E9808 in the dune2000.dat There is 00 there if you search it via any hex-editor. Change this value to 01 and start the game (desktop colour depth should be 16-bit and no "run in win95 compatibility mode" or "run in 640x480" should be selected - in fact none of the XP compatibility options for older games should be selected or it will still go fullscreen no matter what). But it won't do you any good unless you accept that it is locked to the upper left corner of the screen ;)

I found it, thank you very much! It is in the dune2000.dat not the executable. But the window is not centered, it appears in the upper left corner and if you move it it will "snap" back into that position. I presume there is no way to center the window somehow...? ;)

@TSHyper: Well, I may be a bit late but some time ago you wrote: "There is a bool here, "gFullScreen" - 004EB008 (raw: E9808), change this to "00" and the game will run in a desktop window, the logic is messy though..." I would like to play Dune 2000 in windowed mode but couldn't find this value in hex in any of the files. Which file do I have to edit or where can I change this value to play Dune 2000 in a desktop window? Thank you very much for any hints in advance.
