QMC2 – SDL MAME Front End for Mac OSX

QMC2 is a GUI for use with SDL MAME and MESS. SDL MAME is much easier to use with a good front end. Just point and click. It originally started as one of the first front ends for UNIX. Go check out their webpage and pick up the app.

Download the latest build of QMC2 for Mac OS X (x86) here: qmc2-0.2.b20.dmgQt-wise, the package is self-contained, that is it already includes the Qt 4 framework (4.7.3). You only need to additionally install the SDL framework(1.2.14), which is required for MAME & MESS anyway on that platform.

The binaries require Mac OS X 10.4 or higher and have been created and tested on 10.6 (x86 architecture). If you need binaries for a different platform, you’ll have to build them from source (explained in this FAQ).

Please note that there’s a Qt/Phonon bug that may cause a post-mortem crash on exit, which you can safely ignore (though it may be annoying). If it happens to you, there’s nothing we can do about it, but you can disable the annoying crash report dialog if you will:

$ defaults write com.apple.CrashReporter DialogType none

To re-enable the crash report, just replace none with prompt.

You may also look here for builds of intermediate/test releases (and the latest final release): Mac OS X packages


SDL MAME for Mac OSX now sits at .141u4. This is an experimental version. Grab the 64 bit version from the Box File Widget or check out their homepage.

Let’s check out the changes.

Source Changes
Decreased color saturation and alpha of internal fake shifter layout
to make it less distracting. [hap]

Fix OS/2 compile [K.O. Myung-Hun]

Various Aristocrat Mk4 / Mk5 fixes [Palindrome]

Documented Aristocrat Mk4 init procedure [Heihachi_73]

Implemented proper vblank read-back on Aristocrat Mk-4 HW
[Angelo Salese]

naomi: Reorganized the driver to put games in order by type and put
similar functionality together [f205v]

New driver for Winners Circle (Corona), dual CPU hardware.
[Roberto Fresca]

Exposed the M68000 supervisor flag for external MMUs to determine the
current address space. [Curt Coder]

Removed unnecessary machine parameter from device-specific
input_port_read. [Curt Coder]

Exposed the complete Function Code of the M68000 (instead of just FC2
as previously). [Curt Coder]

Corona.c: Fixed the visible screen area to improve the Winners Circle
aspect. Also fixed visible screen area and rotate properly the RE-800
sets. Minor clean-ups. [Roberto Fresca]

Converted core_options to a class. Removed a bunch of marginal
functionality in favor of alternate mechanisms. Errors are now
reported via an astring rather than via callbacks. Every option must
now specify a type (command, integer, float, string, boolean, etc).
Command behavior has changed so that only one command is permitted.
[Aaron Giles]

Changed fileio system to accept just a raw searchpath instead of an
options/option name combination. [Aaron Giles]

Created emu_options class dervied from core_options which wraps core
emulator options. Added mechanisms to cleanly change the system name
and add/remove system-specific options, versus the old way using
callbacks. Also added read accessors for all the options, to ensure
consistency in how parameters are handled. Changed most core systems
to access emu_options instead of core_options. Also changed
machine->options() to return emu_options. [Aaron Giles]

Created cli_options class derived from emu_options which adds the
command-line specific options. Updated clifront code to leverage the
new class and the new core behaviors. cli_execute() now accepts a
cli_options object when called. [Aaron Giles]

Updated both SDL and Windows to have their own options classes,
derived from cli_options, which add the OSD-specific options on top of
everything else. Added accessors for all the options so that queries
are strongly typed and simplified. [Aaron Giles]

Updated nmk/olympia/pacific/pce/phoenix/rare/seibu/seta to
driver_devices. [Atari Ace]

Updated sigma/stern/subsino/tatsumi/tch/tecfri/technos/tehkan to
driver_devices. [Atari Ace]

roul (roul.c) [stephh] :
 * Fixed Dip Switches and Inputs (after verification of the Z80 code)

ksys573: Fix some wrong machine driver selections [O. Galibert]

Allow serial receive without ES enabled. [Couriersud]

sgnascar: Added dump of mask ROMs [Guru, R. Belmont]

Added correct bitswap for point blank 3 [smf].

inptport: Add existence and used bits interface for automatic
controller adaptation [O. Galibert]

Converted psx cpu core to c++ [smf]

Corona.c driver improvements. A lot of input/output work, accurate
periodic interrupt timing for sound CPU, meters, DIP switches, and
other minor things. We got Winners Circle 82 playable. [Roberto

More improvements to corona.c driver. Splitted new machine, memory
map, and complete multiplexed inputs/outputs for Lucky Roulette type
games. Also added NVRAM and inverted blitter [Roberto Fresca]

Implemented MC6845 row/column addressing mode. [Curt Coder]

Make shift/alt+right work on channel volume sliders (fractions between
0 and 1 were always rounded down) [hap]

splash.c driver improvements. [Tomasz Slanina]
 * The Return of Lady Frog : added sound
 * Funny Strip : added sound, patched few more protection checks, fixed
    sprite ram access

Added inputs to Tetris Fighters - game now boots. [Tomasz Slanina]

Lot of improvements/changes to corona.c driver. Input/output work and
new set supported. Redumped the winner82 sound program. [Roberto Fresca]

SDL: Fix uimodekey for MESS [Barry Rodewald, R. Belmont]

More work on corona.c driver. [Roberto Fresca]
 - Cleaned up and improved memory maps
 - Added NVRAM to all winners circle sets
 - Fixed the ay8910 clock for winners circle 82 type to match the other
 - Fixed a blitter buffer to bitmap problem.
 - Reparented the sets.
 - Added new technical notes.

carjmbre: [hap]
 * use 4 bit clut instead of 3 bit
 * calculate palette with resnet info from Popper (same year, same
    company, very similar hardware)
 * make bgcolor emulation more logical
 * small cleanups

Use correct roms for the Japanese 1941 set [Brian Troha]

Fixed sound regression with Mission 660 [Angelo Salese]

Major toaplan2.c updates  [Alex Jackson]
 * Some sets reparented and renamed as well as a cleanup of source
    comments: grindstm (parent), vfive (clone) kingdmgp (parent),
    shippumd (clone) The set formerly known as "sstrikera" is now
    "sstriker" and is now the parent of mahoudai (clone). Reverted
    batrid to batrider and bkraid to bbakraid.
 * Put common init code into MACHINE_START, leaving DRIVER_INITs only
    for games that actually need unique initialization.
 * Dead code cleanup: Removed old hacks and some no-longer-used used
    member variables from the driver class.
 * ROM banking cleanup: Added a device address map for the OKI in
    fixeightbl. Stopped misusing the bank system for memory that isn't
    actually bankswitched (fixeightbl again) Simplified the Z80 ROM
    banking (and loading) in the Raizing games.
 * Address map cleanup: Unified 8-bit shared RAM handling between the
    Z80-based and the V25-based games. Replaced lots of pointless
    READ_HANDLERs with AM_RAM_WRITE. Moved fixeight EEPROM handling
    into the input ports instead of using READ/WRITE_HANDLERs.
    Incidentally, this makes toaplan2.c the very first MAME driver to
    use the AM_READWRITE_PORT macro.
 * Removed IPT_VBLANK input ports (no longer used since the video
 * Removed Truxton 2 player 2 "button 4" (after confirming that the
    game never reads it) and changed player 1 "button 4" to an
    IPT_OTHER not bound to any key by default, since it's clearly some
    kind of test/debug input not meant to be hooked up in a regular
    cabinet (for one thing, it works whether you're actually playing
    or in attract mode)
 * Added button 3 to Batsugun Special Version. It's a full auto fire
    button like Cave games have. The service mode input test doesn't
    show it, presumably because Toaplan didn't bother to update the
    service mode code from the original version of the game.
 * Fixed region jumpers and dipswitches in many sets, based on
    analysis of the program code and strings in the ROMs.
 * Added a #define to optionally make Truxton 2 stereo (commented out
    by default). See the comments at the top of the driver and in the
 * Corrected kbash ROM names, thanks to information from Charles
    MacDonald. Also fixed inconsistent ROM naming between some of the
    batrider clones.
 * Loaded bbakraid default EEPROM as a ROM rather than hardcoding the
    contents into the driver.
 * Completely removed audio/toaplan2.c, which isn't needed any more now
    that all the V25s are decrypted and hooked up.

Technical changes to reel games.  [James Wallace]
 * Fixed lamp timing in MPU4 and laid groundwork for MPU3 support in
    the steppers (I've also cleared up the reel code in drivers).
 * Removed some unneeded timing code.
 * BwB support is here, but preliminary, it's mainly to show people
    how the CHR chip might work in those games.

Fixed enormous memory consumption when iterating through all drivers
like -romident does. [Aaron Giles]

Converted namco/thepit/toaplan/unico/upl/valadon/veltmjr/venture/
vsystem/zaccaria to driver_device. Also simplified unico and
disentangled gridlee from balsente. [Atari Ace]

Breaks some driver entanglements to simplify future driver_device
conversion efforts: [Atari Ace]
 * taito_f3 is disentangled from a number of other drivers by using an
    AM_SHARE tag instead of a common variable.
 * Several drivers are made into explicit subclasses of other drivers:
    8080bw from mw8080bw, missb2 from bublbobl, quasar from cvs,
    taito_x from seta.
 * arcadecl is separated from rampart by duplicating the bitmap
    rendering code.
 * jaleco decryption code is moved to jalcrpt.c.
 * cischeat is separated from megasys1 by duplicating some video code.
 * mcr3 is partly separated from mcr.
 * machine/midwunit.c is split into wunit and xunit files with some
    code duplication.
 * midtunit gfx_rom variables are made distinct from midyunit
    variables, making midyunit independent of midtunit.
 * contants in namconb1 are duplicated/renamed in namcofl.
 * namcos2 uses of namcos21 are eliminated by introducing
 * toypop is separated from mappy by duplicating some video code.

Move non-buffered spriteram drivers away from using the generic
spriteram in favor of using spriteram in their own driver_device
classes. [Atari Ace]

Fix long-standing bug in ABS flags in ADSP21xx core.
[Christophe Jaillet]

Removed some legacy NVRAM_HANDLERs in favor of NVRAM devices.
[Aaron Giles]

Added M48T37 variant to timekpr.c. Fixed some bugs that caused
registers to be initialized to 0xff and caused odd behavior. Updated
to modern device timers. [Aaron Giles]

Converted vegas to use M48T37 instead of its own implementation.
[Aaron Giles]

Attached emu_options to the machine_config, and the running_machine
inherits it now. [Aaron Giles]

Mapped KEYCODE_BACKSLASH2 to the OEM_102 key (located between LShift
and Z on international keyboard layouts). [Curt Coder]

Fix micro3d 8051 serial RX, todo: still needs CLEAR behind a 1 cycle
callback [Lord Nightmare]

Fixed parsing of uimodekey from .ini on SDL [Fabio Priuli]

Improved inputs and complete DIP switches to Lucky Roulette Plus.
Also, added new support for Ruleta RCI. [Roberto Fresca]

model3: add protection data for oceanhun (game still doesn't boot)
[Ville Linde]

galdrvr.c: Added background color split to Anteater. [hap]

Convert a number of drivers to use their own private spriteram instead
of the generic one. Only drivers needing buffered spriteram should use
the shared generic version for now. [Atari Ace]

Continued eliminating global/static variables by moving them to the
driver_device classes.  Mostly drivers from misc.a, and some drivers
recently which had dependencies removed. [Atari Ace]

Fixed Z80-DART transmit word length. [Curt Coder]

Decouple memory_region parameters from the ROMREGION flags. [Aaron Giles]

path_iterator::next() now takes an optional filename to append to the
path. [Aaron Giles]

Fix pleiades colours (high/low palette bits exchanged). [Couriersud]

Added DEVICE_SELF_OWNER support for device callbacks. [Curt Coder]

Moved anteateruk/anteaterg to galdrvr.c [hap]

Added possibility of altering default input port setting for devices.
[Miodrag Milanovic]

Galaxian driver: Fixed sprite X offset. [hap]

Continued moving global/static variables to the driver_device classes.
[Atari Ace]

Remove unused static handler entries. Also ensure that subsequent
mapping/ unmapping of static memory types does not change the memory
parameters. This fixes the case where dynamically unmapping memory
could lead to incorrectly reported offsets. [Aaron Giles]

Remove some straggling const address_space references, and get rid of
explicit const_casts in memory.h. [Aaron Giles]

Dedicated galxwars cabs are not b/w but have color maps For now, use
proms from another game and mark sets as bad dump/wrong colors [hap]

contra.c: Changed main CPU to HD6309 as seen on PCB, and set interrupt
source to k007121. [hap]

Add driver_device classes for drivers that don't have any variables,
for consistency (and future development). [Atari Ace]

Further decoupled some driver files to help driver_device conversions.
[Atari Ace]
 1. cclimber and galaxian audio code and seibuspi decryption code get
     their own includes.
 2. galpani2 video declarations are moved from kaneko16.h to their
     own file.
 3. cchance and champbwl subclass from tnzs, xevious/bosco/digdug
     subclass from galaga and vmetal subclasses from metro.
 4. yvg608 is made independent of namcond1
 5. ettrivia duplicates the palette code from naughtyb
 6. mshuttle decryption code is moved into galaxian.
 7. tetrisp2_draw_sprites is split into two versions, one for ms32.c, one
     for tetrisp2.c.

Converted asteroid/bzone/funworld/itech8/kongambl/legionna/leland/quakeat/
quizpun2/segas24/twincobr/warpwarp to driver_device. [Atari Ace]

Moved Kaneko Super Nova sprite chip emulation inside its own file
[David Haywood]

Put Deco 56 video sprite chip inside its own file [David Haywood]

Deco 56: Allow rendering to a bitmap, with priority data intact, for
manual mixing [David Haywood]

battlex.c: Some driver cleanups, most importantly: [hap]
 * made interrupt generation more logical (assert/clear instead of
 * removed hacky hardcoded palette for background tiles, let it use
    palette ram

Changed clocks based on confirmed XTAL and dumper's notes for Ambush
and clones.  Audio changed to AY8912 as well.
[Tafoid / Tomasz Slanina]

Fixed decrementing transfers in z80dma core [Angelo Salese]

Converted Tattoo Assassins (and Night Slashers) to use deco16ic.c,
fixing some corrupt graphics in Tattoo Assassins (which have been
there since it was first added)  [David Haywood]

Removed globals from a number of device-like shared systems and made them
either statics or actual device variables. [Atari Ace]

Convert cclimber/galpani2/gticlub/namcond1/pacman/seibuspi/tetrisp2/
vicdual to driver_device. [Atari Ace]

Source Changes
- Considerably improved UART communications in the CD-i 68070
implementation, increasing Quizard stability as a result. [Harmony]

Fixed use of the sign bits on the SegaCD Roz parameters, improves
the SegaCD intro rotations etc. which now appear correct. Clamp Roz
stuff to 24-bit, seems to fix the remaining issues with the Sega
logos. [David Haywood]

Moved -effect implementation out of OSD code and into core since the
implementations were identical across Windows/SDL and implemented in
the core itself. [Aaron Giles]

More Clang fixes (verified OK with GCC) [Balrog]

Correctly free textures when screen size dynamically changes. Fixes
texture assert when exiting on a number of games. [Aaron Giles]

Attempt to provide a correct M50458 char rom, used by the Nintendo
Super System [Pat Dardenko, Angelo Salese]

Re-worked Quizard MCU communications handling to be more easily
expanded. [Harmony]

Convert rendlay objects into C++, reduce the number of unused textures
allocated. [Aaron Giles]

Fix texture leak in crsshair.c. [Aaron Giles]

Added new method reset_origin() to screen devices to allow
manual synchronization of VBLANK start against an external timing
source. Updated the MC6845 device to call reset_origin() on its screen
at the start of each frame if a screen is present. [Aaron Giles]

Converted the RCA CDP1802 CPU into a C++ device. Refactored cidelsa.c
to use the new RCA COSMAC CPU. [Curt Coder]

Added new devcb type DEVCB_TYPE_DRIVER, which implies the
driver_device. [Aaron Giles]

specify member functions of the driver device in callbacks.
[Aaron Giles]

Reworked NMK16 irqs by not using cpu_getiloops() function
[Angelo Salese]

Fix custom mapping for dsp56k internal memory. [Aaron Giles]

Refactored the CDP1869 chip into a C++ device. [Curt Coder]

Added explicit control handler for the console. Ctrl+C/Ctrl+Break now
explicitly terminate the process forcefully, rather than unwinding
through the system in an unexpected state. Other console events (exit,
shutdown, logoff) request a graceful exit. [Aaron Giles]

Reworked 1942 interrupts by not using cpu_getiloops() function
[Angelo Salese]

Removed deprecat.h usage from 1943 driver [Angelo Salese]

Removed deprecat.h usage from 40love driver [Angelo Salese]

New Version of SDL MAME for OSX – March 13,2010

There is a new version of Mac MAME and I’m struggling to find ways to make these posts look different then their earlier little brothers. This is the regular, non-experimental, version of MAME. It is now up to date with the .137 baseline. Grab SDL MAME from the Box File Widget or from the homepage. Don’t forget you will want to grab the one that best suits your system. Leopard users go ahead and grab the 64 bit version, for the rest of you grab the 32 bit version.
