Misplaced Pages

Revision as of 21:36, 8 November 2015

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 On the end of life of these video games when no revenue was expected anymore (e.g. superseded by next generation or beyond support life cycle), the source code was released or became available by other means.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. See also Category:Commercial video games with freely available source code

For Open source video game see the List of open source video games. For commercial games which were released as freeware without source code see List of commercial video games released as freeware.

The table below with available source code resulted not from correct releases of companies or IP holders but from unclear release situations, like lost & found and leaks of unclear legality (e.g. by an individual developer on end-of-product-life).

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 program 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.

The community was predictably upset. 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.
