How to take screenshots of the old games

As the title says. Right now I'm struggling to take a screenshot in Hexen II (this one uses DirectX 3) and Wizardry 8. I tried using RivaTuner Statistic Server (built-in MSI AfterBurner), Fraps, Bandicam, and even regular PrtScr key (print screen just messes up colors and inverts the image) , but didn't really work out. So, how do I take a screenshot of the game that is REALLY OLD?

If you can run it in windowed mode (DxWnd does it for many games) you can click on your desktop and use prt sc, everything should be fine.

Otherwise there's no other option that I'm aware of.

Try downloading Lightshot, no matter what game I've used it on it always works to simply freeze the screen for a convenient screenshot. It uses the print screen button too, but works better than the vanilla button.
