Probably the most recent twist in the constant evolution of Mac gaming has been the work of TransGaming, a company that first cut its teeth with a product called Cedega for Linux. Cedega is a website that is dedicated to providing accurate information about the Cedega software which was used by Linux gamers to run Windows games on the Linux platform. The software itself is no longer in use today. It was retired in 2011, a few years after it changed its name to Cedega.
Cedega (formerly known as WineX) was the proprietaryfork 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 DirectXAPI. WineX was renamed to Cedega on the release of version 4.0 on June 22, 2004.
Cedega Gaming Service was retired on February 28, 2011. TransGaming announced that development would continue under the GameTree Linux Developer Program,[1] however this proved moot as the company's core technology divisions were shuttered in 2016.
Licenses[edit]
Though Cedega was mainly proprietary software, TransGaming did make part of the source publicly available via CVS, under a mix of licenses.[2] Though this was mainly done to allow a means for the public to view and submit fixes to the code, it was also frequently used as a means to obtain a quasi-demonstration version of Cedega. TransGaming released a proper demo of Cedega because of complaints of the difficulty of building a usable version of the program from the public CVS, as well as its outdated nature. The demo released by Cedega gave users a 14-day trial of a reasonably current version of the product with a watermark of the Cedega logo which faded from almost transparent to fully opaque every few seconds. This demo was removed without comment.
While the licenses under which the code was released do permit non-commercial redistribution of precompiled public-CVS versions of the software, TransGaming strongly discouraged this, openly warning that the license would be changed if they felt that abuse was occurring or otherwise threatened. TransGaming similarly discouraged source-based distributions like Gentoo Linux from creating automated tools to let people build their own version of Cedega from the public CVS.[3]
The Wine project originally released Wine under the same MIT License as the X Window System, but owing to concern about proprietary versions of Wine not contributing their changes back to the core project,[4] work as of March 2002 has used the LGPL for its licensing.[5]
Functionality[edit]
In some cases it closely mimicked the experience that Windows users have (insert disc, run Setup.exe, play). In other cases some amount of user tweaking is required to get the game installed and in a state of playability. Cedega 5.2 introduced a feature called the Games Disc Database (GDDB) that simplifies many of these settings and adds auto-game detection when a CD is inserted so that settings are applied for the inserted game automatically.
A basic list of features:
- Some types of copy protection
- Pixel Shaders 3.0
- Vertex Shaders 3.0
- DirectX 9.0
- Joystick support including remapping axes
- The ability to run some Windows games
History[edit]
Cedega subscribers dwindled as users expressed a number of complaints[6] due to lack of updates, fatal problems with supported games and with Wine having achieved a number of features that were unique to Cedega, giving even better compatibility in some cases. Users attributed the apparent lack of interest from TransGaming on Cedega to their focus on Cider, a similar Wine-based API layer for Mac OS X systems, supported by Electronic Arts to bring their Windows native games to Mac.[7]
On November 13, 2007's Development Status report, TransGaming explained that a number of modifications have been made to Cedega’s code to add Wine's implementation of the MSI installation system and to be able to incorporate more of Wine’s codebase.[8] It was never confirmed if those changes were in conformance with Wine's LGPL license.
Also on the November 13, 2007 report, it was announced that all of the work done on Cider would be merged back into Cedega (since both share the same code). Among the new features are “new copy protection, 2.0 shader updates, a head start on shader model 3.0, performance upgrades, a self updating user interface” and others.[8]On September 23, 2008, Cedega officially presented the new version 6.1.
Cedega Gaming Service was retired on February 28, 2011.[9]
Controversy[edit]
TransGaming’s business practice of benefiting financially from the Wine project, without contributing anything back to it has drawn criticism. TransGaming obtained the source to the original Wine project when it was under the MIT License and this license placed no requirements on how TransGaming published their software. TransGaming decided to release their software as proprietary software.[10] Cedega includes licensed support for several types of CD-based copy protection (notably SecuROM and SafeDisc), the code for which TransGaming said they were under contract not to disclose.
In 2002 the Wine project changed its license to the GNU Lesser General Public License (LGPL). This means that anyone who publishes a modified version of Wine must publish the source code under an LGPL-compatible license. TransGaming halted using code contributed to Wine when the license was changed, though this has resumed with TransGaming integrating certain LGPL portions of Wine into Cedega and placing those portions of the source code on their public servers.[citation needed]
TransGaming offers a CVS tree for Cedega without copy protection related code and texture compression through its own repositories with mixed LGPL, AFPL and bstring licensing.[11]Point2Play graphical frontend for Cedega is also not found on the CVS.
Scripts and guides have been made by the community to facilitate building Cedega from the source tree.

The company is aligned with Plazacorp, a property development company, which is its major shareholder.[1] The current CEO is Sruli Weinreb.
A former technology company, it was founded by Gavriel State, who ran the Linux product division at Corel. TransGaming's Graphics and Portability Group was acquired by NVIDIA in 2015, paving way to NVIDIA's first office in Canada, located in Toronto.
In 2016, TransGaming Inc. decided to change its business focus from technology and gaming to real estate financing.[2] In August 2016 its last remaining gaming division, GameTree TV, together with its subsidiaries and offices in Tel Aviv and Kyiv, were sold to TransGaming Interactive UK Limited, a subsidiary of General Media Ventures based in the United Kingdom.[3] This company, now renamed to PlayWorks Digital Ltd.[4], carries on the former GameTree TV business under the PlayWorks name.[5][6]
Former technology products[edit]
Cider[edit]
Cider was a technology marketed towards developers that allows Windows games to run on Mac OS X. It shared much of the same core technology as Cedega but was designed for video game designers and publishers. Like Cedega, Cider was a proprietary fork of Wine.
At the 2007 World Wide Developer Conference (WWDC07), Electronic Arts announced their return to the Mac, publishing various titles simultaneously on both PCs and Macs, using Cider on the Mac.[7]
Cedega For Mac Pro
In a newsletter dated 2007-11-13, the company announced that Cider's improvements will be merging back into Cedega.
GameTree Linux[edit]
GameTree Linux was a developer program dedicated to the further development of Cedega, which is a compatibility layer for running Microsoft Windows games on Linux.There are games that run on Cedega but not on Wine, and games that run on Wine but not Cedega. Users that want to play a specific game usually look for it on the games databases available on the web.[8][9]
SwiftShader[edit]
SwiftShader is an advanced software renderer with Direct3D 8/9 class features, including shaders. SwiftShader was sold to Google in 2015 for $1.25 million USD.[10]
GameTree TV[edit]
In 2010 Transgaming launched their new app, GameTree TV, a cloud-based, on-demand entertainment platform for Smart TV. In 2012 Transgaming acquired the connected TV division of Oberon Media and integrated them into their GameTree TV platform.[11]
Cedega For Mac Computers
Digital rights management (DRM)[edit]
In a press release dated 2008-08-20, TransGaming announced that they 'will utilize Sony DADC's SecuROMdigital rights management (DRM) solution for all video game titles enabled through TransGaming's Cider portability engine for Mac games.' TransGaming's use of SecuROM is notable because of the company's decision to use SecuROM technology for all Mac games enabled through Cider, irrespective of distribution channel (download vs. retail) and whether SecuROM was used for a game's Windows PC release.[12][13]
