Their are countless semi-auto weapons found in weasel's "Stranger" wad, yet, i am all the more confounded by how it works. The technique found in the doom armory article doesnt work, as its prone to crashing everytime it goes into the hold state.....

I'm pretty sure it depends on what kind of engine you're using. He's using Gzdoom, so that might be one of the reasons since it has some fancy features not found in many source ports. I'm pretty sure it's impossible in almost all source ports... You could try the Eternity engine. From what I've heard, it's the best engine for Doom.
