'''[[wikipedia:MAME|MAME]]''' (originally an acronym for '''<u>M</u>ultiple <u>A</u>rcade <u>M</u>achine <u>E</u>mulator''') is a multi-platform, open-source, [[Multi-system emulators|multi-system emulator]] written in C++. The philosophy behind the project is to focus on recreating the workings of various machines through emulation, with the software's ability to actually play console games being described as "a nice side effect". MAME is incredibly large, [[MAME compatibility list|supporting thousands of machines and ROM sets]], though what is supported is not what's playable; your mileage may vary. In the event you don't like MAME's own interface, there are [[Frontends#MAME|many alternative frontends]] available.
Much like the name says, MAME was supposed to be for arcade machines like Pac-Man back when it was released in 1997. Over time, MAME has incorporated similar projects out of a necessity to keep development active and prevent duplication of work (as some arcade machines often shared hardware with consoles to ease development of games); the first project to be merged was [[MESS]] at the end of May 2015 starting with version 0.162 and it functioned almost exactly like MAME but for home consoles and other esoteric devices that never got emulated elsewhere. MAME also had a policy against emulating gambling machines, but that decision has since been reversed and the project that aimed to get them working, <abbr title="Arcade Gambling Extensions for MAME">AGEMAME</abbr>, has also been merged. Gaelco Futbol 3 hardware (their rides had nothing to do with soccer), Falgas M89 and Happy Video are only "very small" motion simulators added to the MAME.

We have an outdated compatibility list [[MAME compatibility list|here]]. Although, it focuses on arcade machines, and popular computer & console platforms, it is worth updating. It is highly recommended to instead check the home page on this wiki for any listed computer, console or other gaming device that may have emulation in MAME. You can see the upcoming version's changelog [http://mameinfo.mameworld.info/ here]. Other compatibility lists:

This list has been criticized by MAMEDevs for being overly biased towards RetroArch.

===History===
MAME was first released on February 5, 1997 by Nicola Salmoria as a Pac-Man emulator,<ref name="worldofstuart">[http://worldofstuart.excellentcontent.com/mameover.htm MAME OVER] (0.99)</ref><ref name="History">{{cite web|url=https://www.youtube.com/watch?v=VgJF18Pm7MA|title=A Brief History of Emulation: MAME|publisher=Youtube|accessdate=2018-09-14|date=2017-12-02}}</ref> but before he could do any more work on the project he handed it over to Mirko Buffoni in April 1997 after being required to do National Service in the Italian army.<ref name="worldofstuart"/> Since then, even as early as 2003, the emulator has become very extensive, with the majority of arcade system boards from the 1970's1970s, 1980's 1980s and early 1990's 1990s supported.
MAME originally used a custom BSD license that prohibited commercial use in a few ways. This was mainly used to deter arcade operators from monetizing an emulated version of a widely available commercial title like Pac-Man. However, the MAME team didn't have the funds to afford prosecutors, so this was never effectively enforced. Through an extensive relicensing process in 2016, the project completely changed to a combination of GPL/BSD where applicable. This allowed them to merge the codebase for the MEWUI frontend into the main application starting with version 0.171 (February 2016).
===Support===
You can support the efforts of MAME developers, dumpers and other stakeholders with donations or resources to procure PCBs (Printed Circuit Boards) of arcade games, and all other computing or electronic devices that have digital screen output and in most cases, audio support; upload materials such as artwork of arcade cabinets, special handheld units and pinball tables, among other hardware examples.

==How to==
===Convert Bin/Cue files to CHD===
Many emulators other than MAME are beginning to support Compressed Hunks of Data, mainly because compared to the alternatives, it offers compression (or ''better'' compression) on all fronts. [[Libretro]] is making an initiative to support them thanks to a successful bounties initiative, and in many cores such as their [[Mednafen|Beetle]] fork, they've begun rolling it out for certain platforms like Saturn and PlayStation , so people can test it.
If you're interested in trying it out for yourself, this guide will show you how to convert to the format using MAME's command-line tool called <code>chdman</code>. We'll warn you now that you will need to know how to use either a Unix shell or the command prompt in order to use it. The developers of MAME seemingly don't have plans to give <code>chdman</code> an interface , so if the thought of going back to the DOS days scares you too much, you may have to wait.

:''Note: If you're confident, you can delete files immediately instead of sending them to the recycle bin or trash bin using the keyboard shortcut <code>Shift</code> + <code>Delete</code>. Always back up the files if you're worried you might do it wrong.''
MAME keeps a database of romsets including what each file should be named. If the ROM dump is obtained through a ZIP file, you can uncompress the files inside and transfer them to a 7-Zip file for better compression. The 7-Zip archive HAS to have the exact same name (not the same file extension , obviously).
In case you're wondering why 7-Zip is supported in MAME and not RAR, it's because the LZMA development kit that's developed alongside 7-Zip is in the public domain, and the MAME team uses it for CHDs along with FLAC for audio and data compression; RAR is a proprietary format that can only be decompressed by 7-Zip, not compressed to, as per an agreement with both development teams.
