tinyE: Wolfen as in the movie or am I totally screwed up wrong here?

To play in the Quakespasm sourceport do the following (This worked for me):

1. Unzip the dopa.bat and pak0.pak from the download
2. Rename pak0.pak to pak2.pak
3. Move dopa.bat and pak2.pak to the id1 subfolder in your Quake installation files.
4. Play!

I have no idea how to do this in other ports of Quake or software/DOS Quake. I'm not that experienced with Quake. :P

Wishbone: It seems to work fine in Darkplaces as well, but for that you don't need the .bat file.

hyperagathon: No need for the renaming and shuffling about, just do

quake -game dopa

where "quake" is your source port of choice and "dopa" is the path to the directory containing this episode.

So, assuming you're using quakespasm and are currently in the directory where you've unpacked dopa:

quakespasm -game dopa

On Linux, putting it in your .quakespasm makes typing out paths / getting to the directory unnecessary.

haydenaurion: That didn't work for me on Quakespasm, though I may have had files in the wrong location.
