Screenshotting The Ultimate Doom

[Twinnrova]

How can I take a screenshot of this game and upload it to steam?

I'm playing through DOSBox without any mods. I really would like to take a few screenshots and upload them to Steam, but I'm not sure how to screenshot in DOSBox or how to upload pictures to Steam without the Steam interface within the game.

Any solutions?

I wrote a guide on how to set the game up with modern ports, it might help you.

Note that Steam Overlay won't work with DosBox or Chocolate Doom, at least I haven't found a way. Newer OpenGL ports can however, like GZDoom.

I got screenshots to work with GZDoom and Zandronum.
