I downloaded the games and got the icons on my desktop but when i click them, it opens up dosbox and i am left staring at a blank screen. i thought the game was being loaded but i waited 15 minutes and it didnt pop up, Any solutions?

how do i do that? all i usually do is click the downloaded game and nothing comes up but black screen

Run the graphic mode setup in the game's Start Menu folder and try changing the "graphic mode" box to something else (e.g. "Surface") until you get one where you can see the game.

The graphic mode setup settings are saved separately for each game so repeat as needed for any other games that have the same problem.

Either try Arkose's method and if that doesn't work then go into where you installed the games usually c:\program files\gog.com\The Savage Empire and c:\Program Files\GOG.com\Martain Dreams this is also where you will find a file called secret answers
which gives you the answers to the game's copy protection. There open dosboxSAVAGE and dosboxMARTIAN with notepad and edit the line output= to something else like DDdraw, Surface, or OpenGL

save and then run the game, still doesn't work try a diffrent render option for Output= one should work.
