MAME is now Free and Open Source Software
The MAME (Multiple Arcade Machine Emulator) project has announced a license change,
moving from the old, unique "MAME License" to the GNU GPLv2-or-later
for the full codebase, with many individual components available under
the 3-clause BSD License. The announcement notes that a considerable
effort went into the relicensing process: "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.
" The old license
