<p><b>New page</b></p><div>=== ScummVM is a free (and open source) software. Does that mean I can do anything I want with it? ===<br />
Not quite. Using a free software comes with certain rights, but also certain obligations. At its core Free Software rely on a set of four freedoms:<br />
* Freedom 0: The freedom to run the program for any purpose.<br />
* Freedom 1: The freedom to study how the program works, and change it to make it do what you wish.<br />
* Freedom 2: The freedom to redistribute copies so you can help your neighbor.<br />
* Freedom 3: The freedom to improve the program, and release your improvements (and modified versions in general) to the public, so that the whole community benefits.<br />
<br />
Based on these, there are many different free software licenses that each have their own set of rights and obligations. ScummVM is using the [https://github.com/scummvm/scummvm/blob/master/COPYING GNU General Public License version 2].<br />
<br />
You can read more on the wikipedia page: https://en.wikipedia.org/wiki/Free_software<br />
<br />
=== Can I sell a game using ScummVM? ===<br />
Yes you can, but there are requirements you need to fulfil (see the next question). One important aspect is that while the executable is governed by the GPL license, this does not cover the game data. So you are not obliged to also provide the source for the game data for free.<br />
<br />
=== So what are the obligations if I want to use ScummVM to release my commercial game? ===<br />
You need to comply with the [https://github.com/scummvm/scummvm/blob/master/COPYING GPL v2 license] used by ScummVM. In a nutshell this means that:<br />
* You need to provide in the software a notice that the game executable (or part of it) is subject to the GPL license together with the full text of the license.<br />
* (Is it also required to distribute the copyright file with the game? - You need to provide the [https://github.com/scummvm/scummvm/blob/master/COPYRIGHT ScummVM copyright file] with the game.)<br />
* You need to provide the full and exact ScummVM source code you used, whether you modified it or not. It can for example be provided with the software, or you could have a link on your web site or store page to download it separately. If it is not provided with the game, you need to ensure that users can easily find the source code at the time they download the game.<br />
<br />
Additional sources:<br />
* https://www.softwarefreedom.org/resources/2008/compliance-guide.html<br />
* http://www.gnu.org/licenses/gpl-faq.html<br />
<br />
=== If I sell a game that uses ScummVM, am I required to contact the ScummVM project beforehand so that they are aware of it? ===<br />
No, but we would definitely welcome such approach. See http://www.scummvm.org/contact/ for information on how to contact us.<br />
<br />
=== If I use ScummVM for my commercial game, do I need to credit the ScummVM project? ===<br />
No, you don’t need to do it. However we would of course appreciate if you do it. This could include:<br />
* Indicating on the store page for your game that it uses [http://www.scummvm.org ScummVM], which is licensed under the GPL v2. This might be a good place to also provide a link or indication on how to get the source code you are using (see the obligations in the previous question).<br />
* Indicating in the documentation for your game that you are using ScummVM.<br />
* Keeping the splash screen that briefly shows the ScummVM logo when starting the engine.<br />
<br />
=== If I modify the source code for my private use, do I need to make the source code available to others? ===<br />
No. You only need to make the source code available if you distribute your modified executable. We however encourage you to make the source code available (for example by using a free account on [https://github.com github]) as it may be of interest to others.</div>Criezy
