Thanks. Ok I installed chocolate doom- but how do I get to the command line (sorry, I'm tech challenged)? I can launch the game by double clicking the .exe but no command line shows. I also tried using Run to point to the directory & then appended " -fast" to the end, and that didn't work (game launches but monsters aren't fast). Example D:\Downloads\chocolate-doom-2.2.1-win32\chocolate-doom -fast
