This fork's goal is for improving the accuracy of the SH3 / SH4 implementation within MAME.

The MAME project as a whole is made available 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. A great majority of the source files (over 90% including core files) are made available under the terms of the 3-clause BSD License, and we would encourage new contributors to make their contributions available under the terms of this license.

Please note that MAME is a registered trademark of Gregory Ember, and permission is required to use the "MAME" name, logo, or wordmark.
