OpenMW: A reimplementation of The Elder Scrolls III: Morrowind

OpenMW is an attempt at recreating the engine for the popular role-playing game
Morrowind by Bethesda Softworks. You need to own and install the original game for OpenMW to work.

Version: 0.17.0
License: GPL (see GPL3.txt for more information)

Font Licenses:
EBGaramond-Regular.ttf: OFL (see OFL.txt for more information)
VeraMono.ttf: custom (see Bitstream Vera License.txt for more information)


Run the installer.

Ubuntu (and most others)
Download the .deb file and install it in the usual way.

Arch Linux
There's an OpenMW package available in the AUR Repository:

Open DMG file, copy OpenMW folder anywhere, for example in /Applications


TODO add description here


The data path tells OpenMW where to find your Morrowind files. From 0.12.0 on OpenMW should be able to
pick up the location of these files on its own, if both Morrowind and OpenMW are installed properly
(installing Morrowind under WINE is considered a proper install).

If that does not work for you, please check if you have any leftover openmw.cfg files from versions earlier than 0.12.0. These can interfere with the configuration process, so try to remove then.

If you are running OpenMW without installing it, you still need to manually adjust the data path. Create a text file named openmw.cfg in the location of the binary and enter the following line:

data=path to your data directory

(where you replace "path to your data directory" with the actual location of your data directory)
