Cedega

Cedega (formerly known as WineX) is TransGaming Technologies' proprietary fork of Wine (from when the license of Wine wasn't the LGPL but the X11 license), which is designed specifically for running games written for Microsoft Windows under Linux. As such, its primary focus is implementing the DirectX API.

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