{{copy edit|date=December 2016}}


The [[source code]] of these commercially developed and distributed [[video game]]s is available to the public or the games' communities.


== Motivation ==
{{Orphandate=October 2016}}
Commercial video games are typically developed as [[Proprietary software|proprietary]] [[closed source]] [[software product]]s, with the source code treated as a [[trade secret]] (unlike [[open-source video game]]s). When there is no more expected revenue, these games enter the [[end-of-life (product)|end-of-life]] as a product with no support or availability for the game's users and community, becoming [[abandonware]].
The '''Punjab Right to Service Act''' is an Act of [[Government of Punjab, India]] that came into force on 28 July 2011. The objective of this Act is to deliver services to the people of the state within time limits.<ref>{{cite weburl=http://rtspunjab.gov.in/title=Right to Service Commission Punjab:Homewebsite=rtspunjab.gov.in}}</ref> This Act was enacted on the recommendations of [[Punjab Governance Reforms Commission]].


== Description ==
==Services covered under Punjab Right to Service Act==
In several of the cases listed here, the game's developers released the source code expressly to prevent their work from becoming abandonware. Such source code is often released under varying (free and non-free, commercial and non-commercial) [[software license]]s 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 (programming language)|Python]], and distributed as raw source code without being [[Compiler|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 file]]s through time-demanding [[reverse engineering]] techniques.
The [[Government of Punjab, IndiaGovernment of Punjab]] has notified 351 services<ref>{{cite weburl=http://rtspunjab.gov.in/notifiedservics.aspxtitle=Right to Service Commission Punjab : Notified Serviceswebsite=rtspunjab.gov.in}}</ref> under [[Punjab Right to Service Act 2011]] vide notification no: 5/27/2014-2GR-2/425953/1 dated 02.03.2015 and no. 5/27/2014-2GR-2 (PF)/668042/1 dated 15.01.2016.Initially number of services covered under the Act was 206 <ref>{{cite weburl=http://economictimes.indiatimes.com/news/politics-and-nation/punjab-government-notifies-206-services-under-right-to-services-act/articleshow/46503622.cms?intenttarget=notitle=Punjab government notifies 206 services under Right to Services Actfirst=last=PTIdate=9 March 2015publisher=via=The Economic Times}}</ref> which was increased to 351 vide above mentioned notification no dated 15-01-2015.As per Act delivery of these services has been made time bound.In case of delay the concerned official(s) will be answerable to the authorities and affected person(s) may appeal to the designated officers/Appellate Authority.For this purpose First Appellate Authority, Second Appellate Authority has also been notified.
Source code availability in whatever form allows the games' communities to study how the game works, make modifications, and provide technical support themselves when the official support has ended, e.g. with [[unofficial patch]]es to fix bugs or [[source port]]s to make the game compatible with new [[Computing platform|platforms]].

When much time and manual work is invested it is however still possible to recover or restore a source code variant which replicates the program's functions accurately from the binary program. Techniques used here are [[Decompiler|decompiling]], [[Disassembler|disassembling]] and [[reverse engineering]] the binary [[executable]]. This approach typically does not result in the exact original source code but a diverging version as a binary program does not contain all information originally carried in the original source code. Comments and function names cannot be restored if the program was compiled without additional [[Debugging|debug]] information. The here given in "[[bottom up]]" development methodology re-created source-code of games is able to replicate the behaviour of the original game exactly ("clock-cycle accurate", "pixel-per-pixel accurate"), unlike [[game engine recreation]]s which are often made in [[top down]] methodology resulting in general [[game engine]]s and not accurately representing the original game.

===Simplified application proforma===
To avail the services a standardised and simplified application proforma was introduced for the convenience of the citizen. Earlier there were not only different types of proformas in different offices to avail these services but they varied also from district to districts. In addition to it earlier a lot of undesired documentation was involved in old proformas which was curtailed and documents specifically related to the service only were made mandatory in the simplified proformas. Specimen of the simplified proforma is given below:

Revision as of 05:31, 21 July 2017

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

Motivation

Commercial video games are typically developed as proprietary closed source software products, with the source code treated as a trade secret (unlike open-source video games). When there is no more expected revenue, these games enter the end-of-life as a product with no support or availability for the game's users and community, becoming abandonware.

Description

In several of the cases listed here, the game's developers released the source code expressly to prevent their work from becoming abandonware. 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. Source code availability in whatever form allows the games' communities to study how the game works, make modifications, and provide technical support themselves when the official support has ended, e.g. with unofficial patches to fix bugs or source ports to make the game compatible with new platforms.

Games with reconstructed source code

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.[596][348][597][598][599][600][601] On the closure of Atari in Sunnyvale, California in 1996, the original source code of several milestones of video game history (like Asteroids or Centipede) were thrown out as trash.[602][603]

When much time and manual work is invested it is however still possible to recover or restore a source code variant which replicates the program's functions accurately from the binary program. Techniques used here are decompiling, disassembling and reverse engineering the binary executable. This approach typically does not result in the exact original source code but a diverging version as a binary program does not contain all information originally carried in the original source code. Comments and function names cannot be restored if the program was compiled without additional debug information. The here given in "bottom up" development methodology re-created source-code of games is able to replicate the behaviour of the original game exactly ("clock-cycle accurate", "pixel-per-pixel accurate"), unlike game engine recreations which are often made in top down methodology resulting in general game engines and not accurately representing the original game.

It was megabytes of undocumented, disorganised, messy assembly language. Andy Clitheroe, the lone programmer of both games, must have been some kind of genius, I think. The official release was of the TKG source code. However, when poking around the CD I found the original (and equally messy) AB3D source too." (archived, 2009)

Before there was a Leisure Suit Larry, Chuck Benton created the only non-graphic game Sierra ever sold, Softporn for the Apple ][. I later used its puzzles as the basis for LSL1: Leisure Suit Larry in the Land of the Lounge Lizards. Still later, Gary Thompson reprogrammed it for the IBM PC. Here's your chance to see whether the changes I made to this classic game were improvements or not!

When the original developers of Star Control 2 contacted the online Star Control fan community, they presented an enticing question: if they released the source to the 3DO version of Star Control 2 under GPL, would anybody be interested in porting it to modern-day computers? Michael Martin, a 26-year-old Ph.D. student at Stanford University, answered the call. After removing proprietary 3DO-specific components from the code, the developers released the source for Star Control 2 to the public. {{cite web}}: Unknown parameter |deadurl= ignored (|url-status= suggested) (help)

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.

The source code will now be distributable more freely, under a licence agreement similar to the GPL (GNU Public Licence)."
