xoreos is an open source implementation of BioWare's Aurora engine and its derivatives, licensed under the terms of the GNU General Public License version 3 (or later). The goal is to have all games using this engines working in a portable manner, starting from Neverwinter Nights and ending with Dragon Age II.
The following games are valid targets for xoreos:
- Neverwinter Nights
- Neverwinter Nights 2
- Knights of the Old Republic
- Knights of the Old Republic II: The Sith Lords
- Jade Empire
- Sonic Chronicles: The Dark Brotherhood
- The Witcher
- Dragon Age: Origins
- Dragon Age II
Currently, the "foundation" work of managing resources, reading many basic file formats, displaying graphics and playing sounds has been done. Some games show a working menu or even partial ingame graphics and working scripts, but no actual "normal" gameplay is implemented yet.
For further information about the status of specific games, please visit our wiki.
Note: We are always looking for people to join our efforts in reimplementing those games. Right now, the most pressing matter is a rewrite of the graphics stack. Please see the related blog post.

First, you need to fully install and/or copy the game you want to play with xoreos onto your hard disk. How you do this depends on the game, your operating system and where/how you have bought the game.
xoreos does not yet have a launcher GUI or anything like this. You need to start it from the command line. Run xoreos with the command line option "--help" (without the quotes) to get a help text about further command line options.
The quickest way to start a game in path /path/to/game/ would be to call
If you're on Windows and the path is, say, D:\Path\To\Game\, call
In general, xoreos can read the configuration which game to run from either the command line, a config file or both. Additionally, when you first specify a new game on the command line, xoreos will add a related entry in the config file (creating it first, if necessary).
To accurately identify a specific instance of an installed game, xoreos uses the concept of a "target". Each target has a separate section in the config file, and each of their options apply only to that target. The special target "xoreos" is a global section applying to all games, although the same option in a game target overrides the global option.
[xoreos] width=1024 height=768 fullscreen=false [nwn] path=/home/drmccoy/games/nwn/ fullscreen=true volume_music=0.500000 volume_sfx=0.850000 volume_voice=0.850000
You can then start the game with the target "nwn" with
and xoreos will do the rest. This will start the game in the path /home/drmccoy/games/nwn/, running it in fullscreen at 1024x768.
As you can see with the volume options, xoreos also saves settings you made in the game' actual GUI into the target's section of the config file.
The place where xoreos expects the config file depends on your operating system:
- On GNU/Linux, the place is $XDG_CONFIG_HOME/.xoreosrc. $XDG_CONFIG_HOME defaults to $HOME/.config/
- On Mac OS X, the place is $HOME/Library/Preferences/xoreos\ Preferences/.xoreosrc
- On Windows, the file is called xoreos.ini and is in the subdirectory xoreos in either $APPDATA or $USERPROFILE, depending on your Windows version
