According to a post on the
 
  mamedev website
 
 , the MAME (and MESS) open source license are now OSI-compliant and FSF-approved which makes it officially free and opensource software.
 
 
We can create, modify and distribute MAME/MESS binaries as long as the GPL-2.0+ license and source are being provided.
