What is MAME?

MAME is a multi-purpose emulation framework.

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 (originally stood for Multiple Arcade Machine Emulator) 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.

MAME 0.237

27 Oct 2021

For everyone who’s waited patiently all month, MAME 0.237 is out today! As well as the updates to the UI and debugger that we’ve already announced, there are several updates to the included plugins:

  • A brand-new input macro plugin.
  • The data plugin can now show text from the Japanese command.dat file (or a Chinese command.txt file if you rename it to command.dat).
  • The location the hiscore support plugin uses to store its data and configuration has changed. You won’t lose your high scores, but you need to move the .hi files from the hi folder to the hiscore folder in your plugin data (homepath) folder.
  • The configuration format for the autofire plugin has changed. Unfortunately, you will need to add your autofire button settings again.

Interesting machines added this month include a Mexican TRS-80 Color Computer clone, Tronica Thunder Ball (a re-skin of Space Rescue with a nautical theme), the original version of Pengo that the widespread bootlegs seem to be based on, the original hardware revision of the Laser 128 (Apple II clone), and a slightly older version of Street Fighter Zero 2 Alpha for Asia.

Master of multi-memory controllers kmg is still on a roll broadening NES/Famicom and clone cartridge compatibility. Highlights of the month include:

  • Railway management simulator A Ressha de Ikou.
  • Recent NES/Famicom games released by Ancient to promote Gotta Protectors (Minna de Mamotte Knight). NES development is still alive over two decades after the last licensed title was released in 1995.
  • The two Korean Brilliant Com (영재컴) edutainment games.
  • Some multi-game cartridges featuring the ambitious Titenic game, inspired by a highly successful James Cameron film.
  • Kart Fighter – using the engine from an unlicensed NES port of Street Fighter II, and unlicensed depictions of the character roster from Super Mario Kart, this is almost a premonition of Super Smash Bros. It even features Yoshi’s tail smash, and depicts Kinopio (Toad) as a bare-knuckle brawler long before the Mii costume was available for purchase.
  • Well-known low-effort Mario-themed hack 7 Grand Dad. PUSH ↑ START BUTTON. GET ADDITION GAME. AND NOURISH THE BLOOD

Amiga software compatibility has been improved this month, the NEC PC-6001 family has gained a cartridge software list, and another batch of Commodore 64 cassettes has been added. An issue was identified with “fake E7” Apple II cracks that could prevent them from working if they were written out to disks to use on original hardware. Although this didn’t prevent them from being used in MAME, disk images with the issue fixed have been added to the software list. Over a hundred Apple IIgs cracks have been added, too.

Upcoming Changes in MAME

19 Oct 2021

We’re well on our way through the current development cycle, and MAME 0.237 is going to have some significant changes, not just in terms of emulation, but in the user interface and debugger. Don’t worry, no functionality has been removed. In fact, we’ve added several features. It just might take a little while to adjust to the differences.

First of all, we’ve added support for localised system name files, as used by front-ends like Retrofire, MxUI and MAME Plus! Popular files include mame32j.lst (Japanese) and mame_cn.lst (Chinese). You’ll be able to put your preferred system name file in the DATs (or “history”) folder, and select it in MAME’s UI customisation settings menu. UI localisation support is more complete, and MAME 0.237 will include high-quality Chinese and Greek translations, thanks to YuiFAN and BraiNKilleRGR.

Mouse/trackball navigation has been improved (you can even click DIP switches to toggle them), and the system and software selection menus have been tweaked to include more information and make better use of space.

Lots of debugger commands have been enhanced to work better with newer memory system features. We’ve also updated and expanded the debugger documentation, both on our web site and for the built-in help command.

If you’re compiling MAME yourself, Python 2.7 will no longer be supported: compiling MAME now requires Python 3.2 or later (this won’t affect you if you just use MAME, Python isn’t required to run MAME). Most operating systems have included Python 3 for years, and our MSYS64/MinGW build tools for Windows already include Python 3.8 – as long as you have a python3 command, you should be good to go.

Read on for a more complete list of changes.

MAME 0.236

28 Sep 2021

The big event of the day is here! MAME 0.236 is ready for your enjoyment! Sadly, this month marked the passing of Sir Clive Sinclair, who it could be argued did more to put computers into the hands of everyday people than anyone. There’s a small update to MAME’s ZX Spectrum software list in this release.

The effort to dump and preserve protection microcontrollers is still going well. This month’s additions include Juuouki and Wonder Planet. Protection simulation has been removed for Wonder Planet and Space Harrier. Remember, this is a worthy cause that provides multiple benefits: it improves accuracy by taking guesses out of emulation, helps people maintain and repair ageing arcade boards, and simplifies MAME’s code.

MAME’s NEC PC-8001 now supports floppy disks. The PC-8001 and PC-8801 software lists have been reorganised to match, and a big batch of items from the Neo Kobe collection have been added. MAME continues to improve its NES/Famicom cartridge coverage. There are a whole lot of games you can play now, including Chinese RPGs, fighting game bootlegs, and pirate multi-game cartridges. Experience a parallel universe of software of such inconsistent quality that you can’t stop going down the rabbit hole! Saturn emulation has seen a few improvements, with several games that didn’t boot previously reaching playable status this month.

As you might expect, the FM Towns, PC-98 and V.Smile software lists have been updated as usual. A couple of recently dumped prototypes have been added to the SNES and Game Boy software lists. The SpongeBob SquarePants Jellyfish Dodge game has been dumped and emulated, and a Korean version of Sotsugyo Shousho known as Jor-eop Jeungmyeongseo has been found. More pleasant surprises include working emulation for the IDE protection dongle included in Killer Instinct 2 upgrade kit, and some fixes for Atari 8-bit home computers using the ANTIC video chip.

For people with more exotic tastes, MAME has added its oldest working software list additions: Munching Squares and Punchy for the MIT TX-0. There’s also a new disassembler for the DEC VAX architecture. In more mundane news, you can now reduce the proliferation of duplicate ROM sets for families of similar keyboards and other devices.

Of course, there’s lots more going on, and you can read all about it in the whatsnew.txt file, or get the source and 64-bit Windows binary packages from the download page.

MAME 0.235

27 Aug 2021

What’s in store with MAME 0.235? First of all, the lost unencrypted version of Rafflesia has resurfaced, ending a long saga! A genuine copy of Bubble Buster, an early North American version of Puzzle Bobble, has been found, and a prototype of Tecfri’s Sauro known as Sea Wolf has been dumped. This release includes an update to BGFX and fixes for the long-standing issues with YUV decoding, so LaserDisc games can be played with BGFX shaders.

Konami Viper emulation now has sound support thanks to Windy Fairy, and a big batch of unlicensed multi-game cartridges for NES/Famicom are now playable. As usual, the Apple II, FM Towns and PC-98 software lists have been updated with the latest dumps.

You can find out about all the updates in the whatsnew.txt file, or get the source and 64-bit Windows binary packages from the download page.

MAME 0.234

28 Jul 2021

Hi everyone! After four busy weeks, MAME 0.234 is ready! Newly supported systems include Runaway (a licensed version of Sega’s Head On made by Sun Electronics), Konami’s Magical Twin Bee (the European version of Twin Bee Yahhoo!), and Tronica’s LCD hand-held Spider (same program as Space Mission, but with different artwork). Although it was added last month, VS Mahjong Triangle is now working. This is a rare early example of a mahjong game supporting two simultaneous single-player games, or a two-player game – a format popularised a decade later by Psikyo’s Taisen Hot Gimmick.

There have been two significant sets of improvements for 3D arcade games this month: rewritten 3dfx Voodoo Graphics emulation, giving significant performance gains in many cases, and continued development on Konami’s ZR017 and GTI Club hardware. Although not directly related to 3D graphics, bug fixes for the Fujitsu TGP DSP make Motor Raid more playable. We haven’t forgotten 2D arcade games – Namco racing games have seen another round of fixes for missing or incorrectly positioned sprites, and missing sprites are now drawn in Data East’s Chanbara.

For home systems, our friend kmg has been hard at work adding support for pirate NES/Famicom cartridges, and Brian Johnson has fixed a couple of video issues on the Epson QX-10. Kelvin Sherlock added support for the LANceGS card, providing another networking option for Apple II users.

You can read about everything that’s been going on in the whatsnew.txt file, and the source and 64-bit Windows binary packages are available from the download page.

MAME 0.233

01 Jul 2021

Are you ready for MAME 0.233? With dozens of reported issues fixed, over a hundred pull requests merged, and a flurry of development across all areas, our mid-year release is huge! Some of the more interesting machines added this month include several prototype JAKKS Pacific TV Games, the elusive English version of Namco’s Armadillo Racing, and the LCD hand-held game Space Mission from Tronica.

There are lots of new Apple IIgs and Macintosh software list items, tying in nicely with the recently improved emulation of these systems, as well as an update to the Colour Genie collection, and a massive haul of MicroBee floppy dumps. A few more Mattel Juice Box cartridges have been dumped, allowing you to marvel at the poor-quality, 6 frames-per-second video.

Significantly improved systems include the Atari Portfolio, Tandy MC-10, and Tandy VIS. Carl has continued to work on Japanese home computers, and Ville Linde is back this month, bringing a batch of updates for the Konami Hornet platform. Juno First, The Tin Star, The Empire Strikes Back have all had bugs squashed, and some of the last remaining regressions from the Yamaha FM synthesis rewrite have been resolved. David Haywood has turned his attention to bootlegs of games including Final Lap 3, Guttang Gottong, and Alien Storm.

This release includes preliminary sound support for the Super A'Can console. On the topic of sound, some Yamaha synthesisers have been promoted to working, and MAME can now play back standard MIDI files to exercise machines that take MIDI input.

There are several general usability improvements in this release, including updated Chinese and Greek translations, better configuration handling for slot devices, and a few small enhancements to the built-in user interface. Issues with artwork using SVG and Windows DIB (BMP) images on ARM/AArch64-based Linux systems should also be fixed.

As always, you can find much more detail about all the action in the whatsnew.txt file, and the source and 64-bit Windows binary packages are available from the download page.
