An unofficial patch, sometimes alternatively called community patch, is a patch for a piece of software, created by a third party such as a user community without the involvement of the original developer. Similar to an ordinary patch, it alleviates bugs or shortcomings. Unofficial patches do not usually change the intended usage of the software, in contrast to other third-party software adaptions such as mods or cracks.
Motivation
A common motivation for the creation of unofficial patches is missing technical support by the original software developer or provider. Reasons may include:
the software was originally designed to operate in a substantially different environment and may require improvement/optimization (porting)
the developer has gone out of business and is not available anymore[3]
support is not economically viable (e.g. localization for small markets)
a fast solution for a time critical problem (e.g. security holes) when an official one takes too long[4][5][6]
the official developer is unable to cope with the problems[7]
Types
Unofficial patches are also sometimes called fan patches or community patches, and are typically intended to repair unresolved bugs and provide technical compatibility fixes, e.g. for newer operating systems, increased display resolutions[8][9] or new display formats.
While unofficial patches are most common for the PC platform, they can also be found for console games e.g. in context of the emulation community.[10]
Unofficial patches are not limited to technical fixes; fan translations of software, especially games, are often created if the software has not been released locally.[11] Fan translations are most common for Japanese role-playing games which are often not localized for Western markets.[12][13]
Another variant of unofficial patches are slipstream like patches which combine official patches together, when individual patches are only available online or as small incremental updates.
Methods
The most common case is that the source code and the original development tools are not available for the software. Therefore, the faulty software's binary must be analyzed at run time by reverse engineering and debugging. If the problem is found, a fix to the program must be applied. Sometimes only small changes in configuration files or the registry are required, sometimes binary hacks on the executable itself are required to fix bugs. If a software development kit (e.g. for modding) is available, fixes to the content can be easily produced, otherwise the community would need to create their own tools. These found fixes are typically packed to user deployable patches (e.g. with NSIS, Innosetup).
While no court cases have directly addressed the legal ramifications of unofficial patches, similar cases have been tried on related issues. The case of Galoob v. Nintendo found that it was not copyright infringement by a user to apply an unauthorized patch to a system (while the scope was very specific to the Game Genie). On the other hand, the case Micro Star v. FormGen Inc. found that user-generated maps were derivative works of the original game. In Sega v. Accolade, the 9th Circuit held that making copies in the course of reverse engineering is a fair use, when it is the only way to get access to the "ideas and functional elements" in the copyrighted code, and when "there is a legitimate reason for seeking such access". According to Copyright law of the United States 17 U.S. Code § 117, the owner of a copy of a program can modify it as necessary for "Maintenance or Repair",[24] without permission from the copyright holder; an argumentation also raised by Daniel J. Bernstein professor at the University of Illinois at Chicago.[25]
Similar user rights are given also according to European copyright laws. The question of whether unauthorized changes of lawfully obtained copyright-protected software qualify as fair use is an unsettled area of law.[26] An article of Helbraun law firm remarks, in the context of fan translations, that while redistributing complete games with adaptions most likely does not fall under fair use, distributing the modifications as a patch might be legally permissible; however, that conclusion has not been tested in court.[27]
Reception
Reception of unofficial patches is mixed, but by large, copyright holders are ambivalent. When the software is not considered commercially viable unofficial patches are ignored by the copyright holder as it is not seen as a source of lost revenue.[11][28]
There have been seldom cases of cease and desist letters to unofficial patch and fan translation projects.[29][30]
Bug fixes, unhandled exception crash fixes, Windows 8 / 10 / 11 support, more screen resolutions (including 4k and the custom screen resolution generator), DirectX 9 support, G-Sync / FreeSync and high monitor refresh rate fixes, unlimited camera zoom settings, changed low-quality sounds, new options in game (e.g. more population, cycle time of day, disable crowns system and leaders), integrated language changer, integrated private multiplayer server and many more new features (fully customizable), frequently updated.[58]
