Cedega (formerly known as WineX) is TransGaming Technologies' proprietary fork of WINE, which is designed specifically for running games written for Microsoft Windows under Linux. As such, its primary focus is implementing the DirectX API.

The community have managed to keep Wine in touch with developments in Cedega, many of the games and 3D applications run as well as if not better.

WineX was renamed to Cedega on the release of version 4.0 on June 22, 2004.

License

Transgaming makes the source available from a CVS under a non-Free license, and while the license would permit non-commercial redistribution of the software, Transgaming has threatened to close their parts of the source entirely if this would happen. They also strongly discourage distributions like gentoo from using the CVS source and letting people build their own version of Cedega.

Quote from the license:

"Note that while this license does permit certain kinds of non-commercial 
distribution of pre-compiled binary packages of Cedega, doing so on a large 
scale is discouraged, as it affects TransGaming's ability to continue
to improve and develop the code.  TransGaming reserves the right to 
change the license under which TransGaming-owned copyright code is made 
available, and will not hesitate to do so if non-commercial distribution 
of pre-compiled binary packages adversely affects the financing of continued 
development."
