Oh wow randomly found a really good article on Doom source ports, explaining what they are, citing examples, and how to use them. The only thing missing, is my favorite sourceport and launcher: Woof! and Doom Explorer. So, in the spirit of helping any one wanting to get into Doom, I'm pinning this on my profile.
Second link is the github page for Woof as my personal recommendation, but you could also use DSDA-Doom.
And third link is the download page for Doom Explorer, with the caveat that it currently does not have a Linux build and for that I use ZDL instead.
