MAME becomes FOSS
Almost a year after the folks who maintain the Multiple Arcade Machine Emulator or (MAME) said they would make the project completely open source, they've declared the transition a success.
MAME is seen by many developers to be the foremost emulator of arcade games, and while MAME source code has long been freely available for use, it hasn't technically been open source.
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.
