Cedega (formerly known as WineX) was the proprietary fork by TransGaming Technologies of Wine, from the last version of Wine under the X11 license before switching to GNU LGPL. It was designed specifically for running games created for Microsoft Windows under Linux. As such, its primary focus was implementing the DirectX API. WineX was renamed to Cedega on the release of version 4.0 on June 22, 2004.
