Using Morrowind from gog.com with OpenMW

For some time now I have wanted to try OpenMW, the open-source Morrowind engine recreation, but I was lacking the required game resources.

I wanted to get them from gog, as I like their DRM-free, download and play, approach better than steam.

When Morrowind GOTY was on sale recently, I finally bought and downloaded it.

I thought I could simply unzip/cabextract the game files from the setup.exe, but it doesn’t work like that.
7-zip unpacks the executable just fine, but the bulk data is just a ~1.3 GB [0] file which file designates as data.

From the other extracted files it appears to be a innosetup installer and issuing apt-cache search inno (searching for innosetup does not work) turns up innoextract, which does exactly what it says on the tin.

So after running innoextract -e /path/to/setup_tes_morrowind_goty_2.0.0.7.exe you get all the required game data.

Just point openmw at the extracted Morrowind.esm and you are good to go.

FYI: OpenMW will remember the path to the data, so you might put it somewhere where it can stay.
