- Allow stringing multiple callbacks together recursively. Chained callbacks will be read or written in sequence, and each can be configured with its own type and mask/shift/XOR parameters. - Chained input callbacks cannot have overlapping masks (there's no such thing as a free multiplex). Chained output callbacks have no such restriction. - Remove the constant parameter for the LOGGER callback type: it makes no sense for output, was always zero in existing usage, and is now unnecessary with callback chaining. - Change LOGGER behavior for writes to log the user-defined message only if the output as masked is nonzero. With callback chaining, this can be used to monitor when individual bits become active. - Constant read callbacks can no longer have MCFG_DEVCB_XOR or MCFG_DEVCB_INVERT specified (makes no sense in this context). - Add a MEMBANK callback type to allow output bits to be used for bank-switching. - Add ASSERTLINE and CLEARLINE callback types that raise or lower an interrupt line if the selected bit of the written value is active. These are intended for where periodic or ready-pulse signals from devices are used to trigger IRQs that the CPU program will independently acknowledge. - Add MCFG_DEVCB_BIT as shorthand for masking and shifting out an individual bit for a callback. - Removed DEVCB_LINE_DISPATCH_<n>. Where we're going, we don't need line dispatcher devices. The incompatibility of compilers with regard to post-C90 printf string formats is shockingly bad. There seems to be no easy way to format a 64-bit value and please both gcc and clang, let alone MSVC. |

What is MAME?
MAME originally stood for Multiple Arcade Machine Emulator.
MAME's purpose is to preserve decades of software history. As electronic technology continues to rush forward, MAME prevents this important "vintage" software from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the software is usable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully?). Over time, MAME absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in addition to the arcade video games that were its initial focus.
How to compile?
If you're on a *NIX or OSX system, it could be as easy as typing
make
for a MAME build,
make SUBTARGET=arcade
for an arcade-only build, or
make SUBTARGET=mess
for MESS build.
See the Compiling MAME page on our documentation site for more information, including prerequisites for Mac OS X and popular Linux distributions.
For recent versions of OSX you need to install Xcode including command-line tools and SDL 2.0.
For Windows users, we provide a ready-made build environment based on MinGW-w64.
Visual Studio builds are also possible, but you still need build environment based on MinGW-w64. In order to generate solution and project files just run:
make vs2015
or use this command to build it directly using msbuild
make vs2015 MSBUILD=1
Where can I find out more?
- Official MAME Development Team Site (includes binary downloads for MAME and MESS, wiki, forums, and more)
- Official MESS Wiki
- MAME Testers (official bug tracker for MAME and MESS)

Coding standard
MAME source code should be viewed and edited with your editor set to use four spaces per tab. Tabs are used for initial indentation of lines, with one tab used per indentation level. Spaces are used for other alignment within a line.
Some parts of the code follow Allman style; some parts of the code follow K&R style -- mostly depending on who wrote the original version. Above all else, be consistent with what you modify, and keep whitespace changes to a minimum when modifying existing source. For new code, the majority tends to prefer Allman style, so if you don't care much, use that.
All contributors need to either add a standard header for license info (on new files) or inform us of their wishes regarding which of the following licenses they would like their code to be made available under: the BSD-3-Clause license, the LGPL-2.1, or the GPL-2.0.

The MAME project as a whole is distributed 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 files (over 90% including core files) are under the BSD-3-Clause License and we would encourage new contributors to distribute files under this license.
