List of commercial video games with available source code

From Wikipedia the free encyclopedia

For open source video games, see 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.

This is a list of commercial video games with available source code. The source code of these commercially developed and distributed video games is available to the public or the games' communities.

In several of the cases listed here, the game's developers released the source code expressly to prevent their work from becoming lost. Such source code is often released under varying (free and non-free, commercial and non-commercial) software licenses to the games' communities or the public; artwork and data are often released under a different license than the source code, as the copyright situation is different or more complicated. The source code may be pushed by the developers to public repositories (e.g. SourceForge or GitHub), or given to selected game community members, or sold with the game, or become available by other means. The game may be written in an interpreted language such as BASIC or Python, and distributed as raw source code without being compiled; early software was often distributed in text form, as in the book BASIC Computer Games. In some cases when a game's source code is not available by other means, the game's community "reconstructs" source code from compiled binary files through time-demanding reverse engineering techniques.

Games with reconstructed source code[edit]

See also: List of game engine recreations

Once games, or software in general, become an obsolete product for a company, the tools and source code required to re-create the game are often lost or even actively destroyed and deleted.[260][261][262][263][264][265][266] For instance, with the closure of Atari in Sunnyvale, California, in 1996, the original source codes of several milestones of video game history such as Asteroids and Centipede were all thrown out as trash.[267][268]

When much time and manual work is invested, it is still possible to recover or restore a source code variant which replicates the program's functions accurately from the binary program. Techniques used to accomplish this are decompiling, disassembling, and reverse engineering the binary executable. This approach typically does not result in the exact original source code but rather a divergent version, as a binary program does not contain all of the information originally carried in the source code. For example, comments and function names cannot be restored if the program was compiled without additional debug information.

Using the techniques listed above within a "bottom-up" development methodology process, the re-created source-code of a game is able to replicate the behavior of the original game exactly, often being "clock-cycle accurate", and/or "pixel-per-pixel accurate". This approach is in contrast to that used by game engine recreations, which are often made using a "top-down" development methodology, and which can result in duplicating the general features provided by a game engine, but not necessarily an accurate representation of the original game.

As we celebrate Wing Commander III's first widespread retail availability since the late 1990s, we would like to mention for anyone that we have the game's source code in our offline archive. We know it's frustrating for fans, who could do amazing things with this, to read these updates... but it's also in everyone's best interests to remind EA that we have the raw material from which they could port Wing Commander III to a modern computer or console. Just let us know!

As with Wing Commander I and Wing Commander III, we are pleased to announced that an extremely kind former EA/Origin employee has provided a copy of the Wing Commander IV source code for our preservation efforts! We can't offer it for download at this time, but it is now preserved for future use.

The existence of decaying technology, disorganization, and poor storage could in theory put a video game to sleep permanently -- never to be played again. Troubling admissions have surfaced over the years concerning video game preservation. When questions concerning re-releases of certain game titles are brought up during interviews with developers, for example, these developers would reveal issues of game production material being lost or destroyed. Certain game titles could not see a re-release due to various issues. One story began to circulate of source code being lost altogether for a well-known RPG, preventing its re-release on a new console.
