After lot of years being under MAME own license (prohibiting any commercial use) and therefore not open source, we are finally moving towards becoming officially open source project. Idea is to keep core under BSD3 license and rest is up to developers that created code (drivers and devices emulation). (options are BSD3, LGPL2 or GLP2)

Hopefully this will bring more new developers to MAME project and give more life to project itself.

Please note that MAME trademark is still valid the "MAME" name and MAME logo may not be used without first obtaining permission of the trademark holder.

If you have contributed in past and we still did not contact you please contact us at mamedev@mamedev.org.
