Here are downloads for MAME/MESS on non-Windows platforms including Mac OS X, Linux, and BSD family operating systems.

Technical support for MAME on non-Windows platforms and for MESS on all platforms is available on the bannister.org forums.

Source code download

The following links are for source code, either pre-packaged by MAMEDev or you can simply clone/fork us on Github to follow the team's progress in real-time. Download these if you'd like to learn to develop for MAME/MESS, or if you know how to build the emulator and just want to follow along quickly.

MAME/MESS releases http://mamedev.org/release.html
Live MAME/MESS WIP on Github https://github.com/mamedev/mame

A guide to building MAME/MESS on Mac OS X is available here. An equivalent guide for Linux is available here.

Regularly Updated binaries and packages (usually within a few versions of baseline)

These links are for binaries and/or distribution packages for Mac OS X, the BSD family, and a variety of popular Linux distributions. Download these if you can't or don't wish to build MAME and don't mind waiting for the next release date to see progress. Please Note: In all source release versions starting with 0.162, MAME is a binary which consists the entirety of source (including the former MESS project). As a result, MESS links here will likely only be available up to 0.161 with anything beyond expected to be obtained at the MAME link. For the time being, old MESS can be compiled using "SUBTARGET=mess" while older MAME (arcade only) can be made with "SUBTARGET=mamearcade". Support for these older styles of binaries will be discontinued in the near future.
