i personally reccomend using the voidsw sourceport, since its being developed by the eduke32 team, and is rather straightforward to use.

head over to the eduke32 website[www.eduke32.com], and download the version that fits your system the best.

go into your shadow warrior directory. (if you dont know where yours is, right click the game in steam, go to local files, then browse local files)



you should see two folders, a bin folder and a gameroot folder. the gameroot folder contains all of the game data, and the bin folder should contain dosbox as set up when you downloaded the game. go into the bin folder, and delete every file in it. then copy all of the files from your sourceport into the folder and rename the exe file that launches the port "dosbox.exe" (without quotes). if youre using voidsw, your bin folder should now look like this:

now if you launch the game in steam, it should launch your sourceport and track your time in game! if something doesnt work, just reply to this guide with what sourceport youre using and links to screenshots of what happens when you launch it. have fun!
