MAME is now Free and Open Source Software

Tue Mar 08, 2016 1:42 am

http://mamedev.org/?p=422
After 19 years, MAME is now available under an OSI-compliant and FSF-approved license! Many thanks to all of the contributors who helped this to go as smoothly as possible!

We have spent the last 10 months trying to contact all people that contributed to MAME as developers and external contributors and get information about desired license. We had limited choice to 3 that people already had dual-license MAME code with.

As a result, a great majority of files (over 90% including core files) are available under the 3-Clause BSD License but project as a whole is distributed under the terms of the GNU General Public License, version 2 or later (GPL-2.0+), since it contains code made available under multiple GPL-compatible licenses.

If you have contributed to the MAME source code and believe we have not contacted you, please reach out to us at our contact page.

Also, just for clarification, "the MAME project is provided under the GNU General Public License version 2 or later as of Git revision 35ccf865aa366845b574e1fdbc71c4866b3d6a0f and the upcoming release of MAME 0.172. Source files may also be licensed as specified in the file header. The license change does not apply to prior versions of MAME."
