SDLMAME is an “embedded port” of the popular MAME™, by which I mean that although Couriersud and I maintain it, it’s included with the main MAME source tree.

Note: MAME is a console application, use Terminal.app or a frontend!

There are a few principles that guide it’s development:
1) run on Linux/Unix, Mac OS X, and other SDL supported operating systems with as few changes as possible to the base Windows code. This means we can track changes faster than larger more conventional ports such as MacMAME, and we also maintain what I call “Firefox compatibilty” where learning a major app only needs to be done once per application, and it then applies across many operating systems.

2) MAME developers are important. By keeping quickly up to date, we make it easy for people on non-Windows platforms to make and submit changes to the core MAME code, and we offer native implementations of MAME’s multi-window GUI debugger on both Linux/Unix and Mac OS X.

Requirements:
OS X 10.6+
SDL runtime library installed
64-bit Intel
