Multiple Arcade Machine Emulator is a free and open source emulator designed to recreate the hardware of a wide variety of (mostly vintage) computers, video game consoles and calculators.
The aim of MAME is to be a reference to the inner workings of the emulated machines; the ability to actually play the games is considered "a nice side effect". The source code to MAME serves as this documentation. The emulator now supports over seven thousand unique games and ten thousand actual ROM image sets, though not all of the supported games are playable. It worth mentioning that the sister-project MESS was integrated into MAME.
Unofficial recent MAME 32-bit versions are available here..
Windows: Vista SP1+
Linux: Nothing reported
CPU: Intel Core series CPU or equivalent 2.0 GHz+
GPU: modern card with Direct3D 9.0c+ / OpenGL
Most Recent Changes
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.

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.
It’s time for MAME 0.232, and do we have a surprise for you! The incredibly rare Universal game Mrs. Dynamite has finally been found and dumped! This is an early example of a game where you place bombs to kill enemies that walk over them, showing Universal’s flair for cute characters and cutscenes. Mrs. Dynamite is believed to had performed poorly on location tests, and never had a widespread release. The graphics in the version that has been dumped don’t match what’s shown on flyers. Other arcade additions include Dokaben 2 and a prototype of Spinal Breakers.
Namco racing games have taken a leap forward this month. Final Lap has its sprite chip hooked up subtly differently to later games on the System II platform, which had been causing graphical issues on the title screen. Lack of playback status register emulation in the C140 sound chip was causing issues with engine sounds in Final Lap, Suzuka 8 Hours, and Four Trax. The horizontal position of the road layer has also been adjusted to better match videos made using original hardware.
A number of bug fixes allow previously unplayable Japanese home computer games, including µPD7220 issues affecting the Madou Monogatari games on PC-98, the missing 1-bit DAC sound on PC-98, broken sprites in Asuka 120% Burning Fest. on FM Towns, and background bugs on Sharp X68000. Mac media support continues to improve, with working CD-ROM drives on more Macs, and fixes for high density floppy drives. The V.Smile Smart Keyboard is now supported, in US, French, and German variants. Tim Lindner has continued to fix long-standing bugs in Tandy CoCo 3 emulation.
Software list additions include Taiwanese Game Gear cartridges, Master System prototypes, a big batch of software for the Australian MicroBee series, and quite a few add-on ROMs for the Acorn BBC Micro. We’ve also got the latest Apple II floppy dumps and cracks, FM Towns floppies and CDs, and PC floppies.

The Yamaha FM synthesis rewrite is progressing, with the OPL family (including YM2413, YM3526, YM3812, YMF262 and Y8950) done this month. A number of regressions reported against the previous release have also been fixed. Most things should be improved, but if you notice something wrong with a system using one of these chips, be sure to let us know. Warp-1, a very rare Sun Electronics game from the late ’70s, has been added this month. This is an early example of an “into the screen” space shooter.
For as long as it has been emulated, the “3D” stages in Contra have been too easy. This comes down to the functionality of the Konami 007452 chip, which Konami calls a VRC&DMP. Now we know that VRC stands for Virtual ROM Controller, and controls ROM banking. However, the DMP part has been more of a mystery, assumed to be some kind of protection. This month, furrtek worked out that it’s apparently some kind of Divide/Multiply Processor, for 16-bit maths operations that would be unacceptably slow on the games’s pair of 6809-family CPUs. The great news is the game now runs correctly, the bad news is you’ll probably die a lot more.
David “Haze” Haywood is back this month with fixes for several arcade games that have never been quite right. He’s fixed graphical priority issues in SNK’s Beast Busters and Mechanized Attack, improved timing in Seibu Kaihatsu’s Shot Rider, and corrected layer offsets in Mitchell’s Funky Jet. He also added support for a couple of protected Mega Drive bootleg games from Argentina. Recently, David has been streaming MAME gaming sessions, often highlighting under-appreciated games. You can watch the recorded streams on his YouTube channel. Still on the topic of things that have never been right, sasuke has been busy this month. He’s improved the Nichibutsu 1412M2 DAC playback rate and timer period calculation, most noticeable on the Mighty Guy soundtrack, and made Taito’s unicycling game Cycle Maabou playable.
That’s all we’ve got time for here, but you can read about all the additions, bug fixes, and enhancements in the whatsnew.txt file.
Fasten your seatbelts and get ready for MAME 0.230! There are big changes this month, but before we get to that, let’s highlight some of the more routine additions. Several TV games featuring adaptations of popular Hasbro board games are now supported, as well as a couple of VTech systems featuring Dora the Explorer. Several electronic toys and handheld LED game from Mattel and Invicta have been emulated this month. There’s a big update for the Apple II software lists this month, with clean cracks of lots of educational software from MECC.
If you’ve been following along with development, you’re no doubt excited about the new Yamaha OPM/OPN (YM2151, YM2203, YM2608, YM2610, YM2610B, YM2612, and YM3438) sound emulation core. This addresses numerous subtle and not-so-subtle issues, particularly in Sega and Data East games. Windy Fairy and Jennifer Taylor have continued to improve MAME’s support for Konami rhythm games, making beatmania IIDX, Beatmania III, Keyboardmania and ParaParaParadise games playable. Thanks to Happy, a couple more graphics issues with the Hyper Neo Geo 64 have been fixed.
There’s been a lot of work on the Apple IIgs and 68k Mac drivers this month. As well as the flood of machines promoted to working, Apple 3.5" floppy support has been revolutionised, and improvements to ADB GLU microcontroller simulation make the IIgs control panel usable. On the console side, save EEPROM support has been fixed for several Mega Drive games.
Of course that’s not all, and you can read about all the additions, bug fixes, and enhancements in the whatsnew.txt file.
It’s been an eventful month, culminating in the release of MAME 0.229 today. One change that you’ll notice straight away is that the “64” suffix is no longer added to the file name for 64-bit versions of MAME. If you’re unsure, you can see the data model at the end of the window title.
One very elusive Argentinian title has finally made it into MAME this month. We’re very proud to present Ms PacMan Twin, an extensive hack of Ms. Pac-Man with simultaneous two-player cooperative gameplay. Another rarity you can now experience is Midway’s unreleased Power Up Baseball – the NBA Jam of baseball. On the topic of prototypes, Wayne Gretzky’s 3D Hockey Fatality Edition is now supported.
Several TV games for preschool age children from JAKKS Pacific’s Sharp Cookie line have been dumped and emulated, featuring popular characters like Dora the Explorer, Scooby-Doo, Spider-Man and Thomas the Tank Engine. Travelling back a little, Mattel’s representations of Basketball, Hockey, Soccer, and Tag as electronic toys are now supported. Elektronika Autoslalom has arrived from Russia (with love). Another batch of JPM IMPACT fruit machines have been promoted to working this month, making use of new artwork engine features for their internal layouts.
Updates to the Win32 and Qt debuggers add a context menu to debugger views with an option to copy visible text to the clipboard, improve behaviour when views are scrolled to the bottom, and fix a crash when right-clicking some memory views. We’re lucky enough to have received another shader update from cgwg, improving the appearance of the popular crt-geom and crt-geom-deluxe effects. We’ve added support for the NEC/Renesas V850 family to unidasm.
That’s all we’ve got time for here, but there are lots of software list updates, newly dumped bootlegs, bug fixes, and other enhancements that you can read about in the whatsnew.txt file.
Has it already been an entire month? It must have been, because MAME 0.228 is ready today! We’ve added support for two very rare arcade games this month. The first is Namennayo, an overhead-view obstacle course game making unauthorised use of Satoru Tsuda’s Nameneko characters. The second is Get A Way, an overhead-view racing game made by Universal, touted as the “first game in the world to feature a 16-bit microcomputer.” Universal went on to create the much loved Mr. Do! character. Emulation is preliminary – while the game is playable, there are some graphical issues, and sound is absent.
In other arcade emulation news, Windy Fairy has made a triumphant return, bringing numerous fixes for issues affecting Bemani rhythm games running on System 573 hardware. Thanks to the persistent efforts of David “Haze” Haywood, various fruit machines from JPM are starting to become playable in MAME. Interestingly, these machines rely on similar Brooktree RAMDACs to NCD X11 terminals, and Motorola DUARTs used by numerous other systems emulated in MAME. A complete dump of the type 01 program for Zaccaria’s Cat and Mouse has finally been obtained, making both known versions of this obscure game playable at last.
For hand-held consoles, the WonderSwan and WonderSwan Color have had an overhaul, and Game Gear X-Terminator cartridges are now supported. Several Bandai RX-78 cartridges have been dumped, exercising more aspects of the emulation and allowing several shortcomings to be fixed. We’ve also made some progress on emulating Apple’s floppy drive controllers, providing a path to support for SuperDrive high-density floppy drives, and eventually the HD20 external hard disk.
There’s been plenty more happening, including a new LCD shader from cgwg, all the latest FM Towns software dumps, fixes for recent regressions, and more code modernisation. You can read all about it in the whatsnew.txt file
