List of commercial video games with available source code
The video games in this table were originally developed proprietary as commercial closed source software product. On the end of life of these video games when no revenue was expected anymore (e.g. superseded by next generation or beyond support life cycle), the source code was released or became available by other means. Instead of letting these games become unsupported Abandonware, they were opened under varying (free and non-free, commercial and non-commercial) licenses to the game communities or the public. This allows the game communities at least to provide technical support (bug fixes, compatibility adaptations to new hardware and OSs) themselves, e.g. with unofficial patches or Source ports to actual platforms. Artwork and data are seldom released under a free license as the copyright entanglements are often more complicated than with the source code.

When much time and manual work is invested in decompiling, disassembling and reverse engineering the binary executable, it is possible to recover a source code variant of the program. This process will typically lead not to the original source code but to a strongly diverging version as a binary porgram not represents all informations carried in the original source code. Therefore for instance, comments and function names can't be recovered anymore, if the program was compiled as release version without additional debug informations.
|Title||Original release||Source code by decompilation||Genre||Original developer||Additional information|
|Albion||1996||2011||Adventure game||Blue Byte||In 2011 via static recompilation from the original x86 binary executable a port for the ARM architecture of the Pandora handheld was created by fans. The community still updates this recompiled version and released also Windows and Linux builds in 2015.|
|Another World||1991||2011||Platform game||Delphine Software International||In 2011, Fabien Sanglard analysed Another World by reverse engineering and reconstructed a complete C++ source code variant of the internal virtual machine based one a earlier approach.|
|Dungeon Keeper||1997||2005||realtime dungeon simulator||Bullfrog||Tomasz Lis works on reverse engineered version called "KeeperFX" with the resulting source code released as GPLv3.|
|Dungeon Master||1989||2001||Dungeon crawler||FTL Games||In 2001 Dungeon Master (and its successor CSB) was released by Paul R. Stevens in a portable reverse engineered version called "CSBwin". CSBwin was reverse engineered from the game's Atari asssembler code to a pure C version in years of work.|
|Heart of the Alien||1994||2004||Platformer||Interplay Entertainment||After Heart of the Alien became unsupported and unavailable, Gil Megidish took up 2004 the effort of extracting a source code variant from the binary game by reverse engineering to make the game available again on modern platforms. The extracted source code was made open-source and is hosted freely available on sourceforge.|
|Little Big Adventure||1994||2004||Action-adventure||Adeline Software International||Reverse engineered and placed on sourceforge (later GitHub) as "Twin-e" after getting an "OK" by Frederick Raynal.|

|Starcraft||1998||2014||Real-time strategy||Blizzard Entertainment||By static recompilation and reverse engineering of the original x86 version an unofficial version for the Pandora handheld and the ARM architecture became available in 2014.|
|Strike Commander||1993||2013||Flight simulator||Origin Systems||In 2013 a SC reverse engineering project by Fabien Sanglard with a reconstructed source code variant became available on GitHub as the original source code was most probably lost in the take over of Origin by EA (Abandonware).|
|Tennis for two||1958||2008||Arcade||William Higinbotham||In 2008 Tennis for Two, a video game from 1958, was recreated using partly modern parts.|

Instead of giving up on the game, users decided that if Activision wasn't going to fix the bugs, they would. They wanted to save the game by getting Activision to open the source so it could be kept alive beyond the point where Activision lost interest. With some help from members of the development team that were active on fan forums, they were eventually able to convince Activision to release Call to Power II's source code in October of 2003.

Thanks to an extremely kind donation from an anonymous former EA/Origin developer, the source code to the PC version of Wing Commander I is now preserved in our offline archive! Because of our agreement with Electronic Arts, we're not allowed to post recovered source code for download--but rest easy knowing that the C files that started it all are being kept safe for future reference. Our offline archive contains material that has been preserved but which can't be posted, including other source code and budget data from several of the games.

Here is a version for Windows, in case anyone is interested. Unpack it into the directory where Albion is installed - read the Readme for more information (use Albion.cmd to run the game).

I spent two weeks reading and reverse engineering further the source code of Another World ("Out Of This World" in North America). I based my work on Gregory Montoir's "binary to C++" initial reverse engineering from the DOS executable. I was amazed to discover an elegant system based on a virtual machine interpreting bytecode in realtime and generating fullscreen vectorial cinematic in order to produce one of the best game of all time.

Most people assume the source codes and gold versions of all finished games were stored in a Vault somewhere at EA. But after getting in touch with people at Wing Commander CIC, it appeared that all the source code was lost when the company closed.[...]On his first day one developer managed to delete the full 900MB of Strike Commander source tree.
