intended differences from previous behavior. For drivers,
the main change is that input_port_read() no longer exists.
Instead, the port must be fetched from the appropriate device,
and then read() is called.
For member functions, this is actually simpler/cleaner:
value = ioport("tag")->read()
For legacy functions which have a driver_data state, it goes:
value = state->ioport("tag")->read()
For other legacy functions, they need to fetch the root device:
value = machine.root_device().ioport("tag")->read()
The other big change for drivers is that IPT_VBLANK is gone.
Instead, it has been replaced by a device line callback on the
screen device. There's a new macro PORT_VBLANK("tag") which
automatically points things to the right spot.
Here's a set of imperfect search & replace strings to convert
the input_port_read calls and fix up IPT_VBLANK:
input_port_read( *\( *)(machine\(\)) *, *([^)]+ *\))
ioport\1\3->read\(\)
input_port_read( *\( *)(.*machine[()]*) *, *([^)]+ *\))
\2\.root_device\(\)\.ioport\1\3->read\(\)
(state = .*driver_data[^}]+)space->machine\(\)\.root_device\(\)\.
\1state->
(state = .*driver_data[^}]+)device->machine\(\)\.root_device\(\)\.
\1state->
input_port_read_safe( *\( *)(machine\(\)) *, *([^,]+), *([^)]+\))
ioport\1\3->read_safe\(\4\)
IPT_VBLANK( *\))
IPT_CUSTOM\1 PORT_VBLANK("screen")
sound devices for each of the Midway 8-bit sound
boards. This will also aid in eventually hooking them
up to pinballs.
Enhanced the mixer interface support to allow for
more than one output line. To use this you need to
use the MCFG_MIXER_ROUTE macro instead of
MCFG_SOUND_ROUTE so that the mixer output index can
be specified. See midway_ssio_device for an example.
from 4 to 5. This means any diff CHDs will no longer work. If you
absolutely need to keep the data for any existing ones you have,
find both the diff CHD and the original CHD for the game in question
and upgrade using these commands:
rename diff\game.dif diff\game-old.dif
chdman copy -i diff\game-old.dif -ip roms\game.chd -o diff\game.dif -op roms\game.chd -c none
Specifics regarding this change:
Defined a new CHD version 5. New features/behaviors of this version:
- support for up to 4 codecs; each block can use 1 of the 4
- new LZMA codec, which tends to do better than zlib overall
- new FLAC codec, primarily used for CDs (but can be applied anywhere)
- upgraded AVHuff codec now uses FLAC for encoding audio
- new Huffman codec, used to catch more nearly-uncompressable blocks
- compressed CHDs now use a compressed map for significant savings
- CHDs now are aware of a "unit" size; each hunk holds 1 or more units
(in general units map to sectors for hard disks/CDs)
- diff'ing against a parent now diffs at the unit level, greatly
improving compression
Rewrote and modernized chd.c. CHD versions prior to 3 are unsupported,
and version 3/4 CHDs are only supported for reading. Creating a new
CHD now leaves the file open. Added methods to read and write at the
unit and byte level, removing the need to handle this manually. Added
metadata access methods that pass astrings and dynamic_buffers to
simplify the interfaces. A companion class chd_compressor now
implements full multithreaded compression, analyzing and compressing
multiple hunks independently in parallel. Split the codec
implementations out into a separate file chdcodec.*
Updated harddisk.c and cdrom.c to rely on the caching/byte-level read/
write capabilities of the chd_file class. cdrom.c (and chdman) now also
pad CDs to 4-frame boundaries instead of hunk boundaries, ensuring that
the same SHA1 hashes are produced regardless of the hunk size.
Rewrote chdman.exe entirely, switching from positional parameters to
proper options. Use "chdman help" to get a list of commands, and
"chdman help <command>" to get help for any particular command. Many
redundant commands were removed now that additional flexibility is
available. Some basic mappings:
Old: chdman -createblankhd <out.chd> <cyls> <heads> <secs>
New: chdman createhd -o <out.chd> -chs <cyls>,<heads>,<secs>
Old: chdman -createuncomphd <in.raw> <out.chd> ....
New: chdman createhd -i <in.raw> -o <out.chd> -c none ....
Old: chdman -verifyfix <in.chd>
New: chdman verify -i <in.chd> -f
Old: chdman -merge <parent.chd> <diff.chd> <out.chd>
New: chdman copy -i <diff.chd> -ip <parent.chd> -o <out.chd>
Old: chdman -diff <parent.chd> <compare.chd> <diff.chd>
New: chdman copy -i <compare.chd> -o <diff.chd> -op <parent.chd>
Old: chdman -update <in.chd> <out.chd>
New: chdman copy -i <in.chd> -o <out.chd>
Added new core file coretmpl.h to hold core template classes. For now
just one class, dynamic_array<> is defined, which acts like an array
of a given object but which can be appended to and/or resized. Also
defines dynamic_buffer as dynamic_array<UINT8> for holding an
arbitrary buffer of bytes. Expect to see these used a lot.
Added new core helper hashing.c/.h which defines classes for each of
the common hashing methods and creator classes to wrap the
computation of these hashes. A future work item is to reimplement
the core emulator hashing code using these.
Split bit buffer helpers out into C++ classes and into their own
public header in bitstream.h.
Updated huffman.c/.h to C++, and changed the interface to make it
more flexible to use in nonstandard ways. Also added huffman compression
of the static tree for slightly better compression rates.
Created flac.c/.h as simplified C++ wrappers around the FLAC interface.
A future work item is to convert the samples sound device to a modern
device and leverage this for reading FLAC files.
Renamed avcomp.* to avhuff.*, updated to C++, and added support for
FLAC as the audio encoding mechanism. The old huffman audio is still
supported for decode only.
Added a variant of core_fload that loads to a dynamic_buffer.
Tweaked winwork.c a bit to not limit the maximum number of processors
unless the work queue was created with the WORK_QUEUE_FLAG_HIGH_FREQ
option. Further adjustments here are likely going to be necessary.
Fixed bug in aviio.c which caused errors when reading some AVI files.
and paths consistently for devices, I/O ports, memory
regions, memory banks, and memory shares. [Aaron Giles]
NOTE: there are likely regressions lurking here, mostly
due to devices not being properly found. I have temporarily
added more logging to -verbose to help understand what's
going on. Please let me know ASAP if anything that is being
actively worked on got broken.
As before, the driver device is the root device and all
other devices are owned by it. Previously all devices
were kept in a single master list, and the hierarchy was
purely logical. With this change, each device owns its
own list of subdevices, and the hierarchy is explicitly
manifest. This means when a device is removed, all of its
subdevices are automatically removed as well.
A side effect of this is that walking the device list is
no longer simple. To address this, a new set of iterator
classes is provided, which walks the device tree in a depth
first manner. There is a general device_iterator class for
walking all devices, plus templates for a device_type_iterator
and a device_interface_iterator which are used to build
iterators for identifying only devices of a given type or
with a given interface. Typedefs for commonly-used cases
(e.g., screen_device_iterator, memory_interface_iterator)
are provided. Iterators can also provide counts, and can
perform indexed lookups.
All device name lookups are now done relative to another
device. The maching_config and running_machine classes now
have a root_device() method to get the root of the hierarchy.
The existing machine->device("name") is now equivalent to
machine->root_device().subdevice("name").
A proper and normalized device path structure is now
supported. Device names that start with a colon are
treated as absolute paths from the root device. Device
names can also use a caret (^) to refer to the owning
device. Querying the device's tag() returns the device's
full path from the root. A new method basetag() returns
just the final tag.
The new pathing system is built on top of the
device_t::subtag() method, so anyone using that will
automatically support the new pathing rules. Each device
has its own internal map to cache successful lookups so
that subsequent lookups should be very fast.
Updated every place I could find that referenced devices,
memory regions, I/O ports, memory banks and memory shares
to leverage subtag/subdevice (or siblingtag/siblingdevice
which are built on top).
Removed the device_list class, as it doesn't apply any
more. Moved some of its methods into running_machine
instead.
Simplified the device callback system since the new
pathing can describe all of the special-case devices that
were previously handled manually.
Changed the core output function callbacks to be delegates.
Completely rewrote the validity checking mechanism. The
validity checker is now a proper C++ class, and temporarily
takes over the error and warning outputs. All errors and
warnings are collected during a session, and then output in
a consistent manner, with an explicit driver and source file
listed for each one, as well as additional device and/or
I/O port contexts where appropriate. Validity checkers
should no longer explicitly output this information, just
the error, assuming that the context is provided.
Rewrote the software_list_device as a modern device, getting
rid of the software_list_config abstraction and simplifying
things.
Changed the way FLAC compiles so that it works like other
external libraries, and also compiles successfully for MSVC
builds.
almost certainly some regressions lurking. Let me know if
something seems busted.
Bitmaps are now strongly typed based on format. bitmap_t still
exists as an abstract base class, but it is almost never used.
Instead, format-specific bitmap classes are provided:
bitmap_ind8 == 8bpp indexed
bitmap_ind16 == 16bpp indexed
bitmap_ind32 == 32bpp indexed
bitmap_ind64 == 64bpp indexed
bitmap_rgb32 == 32bpp RGB
bitmap_argb32 == 32bpp ARGB
bitmap_yuy16 == 16bpp YUY
For each format, a generic pix() method is provided which
references pixels of the correct type. The old pix8/pix16/pix32/
pix64 methods still exist in the short term, but the only one
available is the one that matches the bitmap's pixel size. Note
also that the old RGB15 format bitmaps are no longer supported
at all.
Converted model1, megadriv, and stv drivers away from the RGB15
format bitmaps.
New auto_bitmap_<type>_alloc() macros are provided for allocating
the appropriate type of bitmap.
Screen update functions now must specify the correct bitmap type
as their input parameters. For static update functions the
SCREEN_UPDATE macro is now replaced with SCREEN_UPDATE_RGB32 and
SCREEN_UPDATE_IND16 macros. All existing drivers have been
updated to use the correct macros.
Screen update functions are now required for all screens; there
is no longer any default behavior of copying a "default" bitmap
to the screen (in fact the default bitmap has been deprecated).
Use one of the following to specify your screen_update callback:
MCFG_SCREEN_UPDATE_STATIC(name) - static functions
MCFG_SCREEN_UPDATE_DRIVER(class, func) - driver members
MCFG_SCREEN_UPDATE_DEVICE(tag, class, func) - device members
Because the target bitmap format can now be deduced from the
screen update function itself, the MCFG_SCREEN_FORMAT macro is
no longer necessary, and has been removed. If you specify a
screen update callback that takes a bitmap_ind16, then the screen
will be configured to use a 16bpp indexed bitmap, and if you
specify a callback that takes a bitmap_rgb32, then a 32bpp RGB
bitmap will be provided.
Extended the bitmap classes to support wrapping a subregion of
another bitmap, and cleaner allocation/resetting. The preferred
use of bitmaps now is to define them directly in drivers/devices
and use allocate() or wrap() to set them up, rather than
allocating them via auto_bitmap_*_alloc().
Several common devices needed overhauls or changes as a result
of the above changes:
* Reorganized the laserdisc base driver and all the laserdisc
drivers as modern C++ devices, cleaning the code up
considerably. Merged ldsound device into the laserdsc
device since modern devices are flexible enough to handle
it.
* Reorganized the v9938 device as a modern C++ device. Removed
v9938mod.c in favor of template functions in v9938.c directly.
* Added independent ind16 and rgb32 callbacks for TMS340x0 devices.
* All video devices are now hard-coded to either ind16 or rgb32
bitmaps. The most notable is the mc6845 which is rgb32, and
required changes to a number of consumers.
* Added screen_update methods to most video devices so they can be
directly called via MCFG_SCREEN_UPDATE_DEVICE instead of creating
tons of stub functions.
parameters for the global SCREEN_UPDATE callback match the parameters
for the driver_device version. Added allocate() and deallocate()
methods to bitmap_t to permit cleaner handling of bitmaps in drivers
and modern devices. [Aaron Giles]
macros with bitmap->pix* functions, and moved bitmap_fill() to bitmap->fill()
among other similar changes. Bitmap fields now only available via accessors.
Replaced sect_rect with &= and union_rect with |= operators for rectangle
classes. Some general cleanup as a result of these changes. [Aaron Giles]
Word around the campfire is this totally works and stuff. More technically, it eliminates a number of double-frees and also now cleans up the shadow mask PNG and hlsl_options allocations. (nw)

This way it is possible to link two or more separated executables with different

No whatsnew: There is no creasing visible to me, using either -window -nomaximize or -nowindow on a 1920x1080 display. If someone can get me a consistently reproducible case, it will be fixed.
Country Entertainment]
- Created two flags, -hlsl_ini_write and -hlsl_ini_read. The former enables
custom HLSL INI writing explicitly, the other enables loading of the same.
- Fixed disappearing aperture effect when using custom INI files.
- Fixed diagonal seam on some games, for serious real this time
- Fixed phosphor simulation, now works as expected
Hand-checked the most popular English word misspellings and made the appropriate changes. Nearly all of the changes made were in commented areas. (no whatsnew)
- MAME will now save an HLSL INI file on the first run of a game that doesn't already have an INI file.
- HLSL INI files must have their parameters left in the order in which they are saved out.
- Fixed a diagonal 'crease' visible on the screen in HLSL mode.
- Fixed set_vector functionality and simplified shaders as a result
- Fixed HLSL presets, 0 to 3, in increasing level of terribleness
- Reduced options footprint from RGB triplets
Next plan: Separate INI writing.
- Reworked default shadow mask settings, eliminating rainbow banding and matching reference shots more closely
- Moved color power to occur after shadow mask, as it is intended to simulate nonlinear phosphor response
- Added a variable-width notch filter to the Y channel in NTSC post-processing, eliminating luma banding on e.g. CoCo 2 and Apple II
Attempting to fix the HLSL 'blurriness' reported by a few people. Now HLSL will auto-prescale to the nearest texture size that is greater than the target screen size on both axes and is also an even multiple of the raw bitmap's size.
- Added the ability to render screenshots at arbitrary resolutions.
- Added the ability to record AVI videos (albeit with no audio) at arbitrary resolutions.
- Added a 43-tap-wide FIR-based NTSC filter with tunable Y, I and Q frequency response.
- Updated scanlines to have a user-tunable pixel-height ratio in addition to the current screen-height ratio.
- Fixed a VRAM leak that was causing many dynamic-resolution drivers to run out of memory mid-run.
Low-level input upgrade. Classes now exist for input_codes, input_items,
input_devices, and input_seqs. Also created an input_manager class to
hold machine-global state and made it accessible via machine.input().
Expanded the device index range (0-255, up from 0-16), and the OSD can
now specify the device index explicitly if they can better keep the
indexes from varying run-to-run. [Aaron Giles]
Note that I've built and run SDL on Windows, but not all the code paths
were exercised. If you use mice/joysticks extensively double-check them
to be sure it all still works as expected.
This is mainly an OSD and core change. The only thing impacting drivers
is if they query for specific keys for debugging. The following S&Rs
took care of most of that:
S: input_code_pressed( *)\(( *)([^, ]+) *, *
R: \3\.input\(\)\.code_pressed\1\(\2
S: input_code_pressed_once( *)\(( *)([^, ]+) *, *
R: \3\.input\(\)\.code_pressed_once\1\(\2
- Created a new OSD function, osd_get_slider_list, which allows OS-specific slider controls.
- Plumbed new OSD-specific slider controls for HLSL parameters on Direct3D 9 targets. And there was much rejoicing.
- Re-worked render target handling to align pixels better, reducing unintentional blurring
- Made major fixes to CVBS simulation, significantly increasing color saturation
- The defocus pass is now switched off when defocus_x and defocus_y are zero, allowing finer-grained performance tuning.
- Removed YIQ convolution from the main color-convolution shader and replaced it with a full composite encode/decode pass. This is slower, but looks amazing(ly like a terrible TV) and can be turned off.
- More authentic NTSC dot crawl and bandwidth limiting.
- Potential fix for some crashing reported by John IV
- Split color convolution and deconvergence into separate shaders for potential GPU savings down the line
- Added light and heavy variants of the color convolution shader, the former with YIQ colorspace removed
- Re-worked defocus to occur prior to shadow mask application, as it would be on a real monitor.
- Removed Edge Detection, as it was just for fun and can easily be added in by users if desired.
- Split "pincushion" into "Pincushion" and "Screen Curvature", the former affecting the only the displayed image and the latter only affecting the shadow mask.
- 5-pass post-processing: Upscale, Post-Process, Store Last Frame, Defocus 1, Defocus 2
- Many tunable effects including: Scanlines, defocus, linear deconvergence, radial deconvergence, pincushion, RGB colorspace convolution, YIQ colorspace convolution, saturation, simulated dot crawl, simulated chroma subsampling, aperture masking, and more.
- Requires a GPU that supports Shader Model 3.0 to be enabled and a powerful GPU, the entire pipeline consists of approximately 30 texel fetches and approximately 230 arthimetic ops.
- Will supersample the framebuffer up to 9x in both X and Y, but this requires an enormously powerful GPU that has not been invented; users with Radeon 5000-class cards should limit themselves to 3x, Radeon 4000 to 1.5x.
- The default configuration will NOT appear to do anything; it requires tuning to the user's liking.
- Should nicely fall back in all cases except missing shaders, and it might fall back correctly in that case as well. Report any anomalies.
- For obvious reasons, the Direct3D8 renderer cannont support this.
- non-device timer callbacks
- machine state changing callbacks
- configuration callbacks
- per-screen VBLANK callbacks
- DRC backend callbacks
For the timer case only, I added wrappers for the old-style functions.
Over time, drivers should switch to device timers instead, reducing the
number of timers that are directly allocated through the scheduler.
existing modern devices and the legacy wrappers to work in this
environment. This in general greatly simplifies writing a modern
device. [Aaron Giles]
General notes:
* some more cleanup probably needs to happen behind this change,
but I needed to get it in before the next device modernization
or import from MESS :)
* new template function device_creator which automatically defines
the static function that creates the device; use this instead of
creating a static_alloc_device_config function
* added device_stop() method which is called at around the time
the previous device_t's destructor was called; if you auto_free
anything, do it here because the machine is gone when the
destructor is called
* changed the static_set_* calls to pass a device_t & instead of
a device_config *
* for many devices, the static config structure member names over-
lapped the device's names for devcb_* functions; in these cases
the members in the interface were renamed to have a _cb suffix
* changed the driver_enumerator to only cache 100 machine_configs
because caching them all took a ton of memory; fortunately this
implementation detail is completely hidden behind the
driver_enumerator interface
* got rid of the macros for creating derived classes; doing it
manually is now clean enough that it isn't worth hiding the
details in a macro
loader rewrite, which is still in progress....)
Replaced mamedriv.c with a new driver list mechanism that is generated
by the build tools. The emulator core now expects the presence of a
file called src/$(TARGET)/$(SUBTARGET).lst which is just a raw list of
driver names, one per line. C and C++ comments are still permitted.
This file is parsed by a new build tool makelist which extracts the
driver names, sorts them, and generates a file called drivlist.c, which
is consumed by the core. [Aaron Giles]
Added new osdcore function osd_malloc_array() which is identical to
osd_malloc() but obviously hints that the underlying allocation is for
an array. Updated all callers to use the appropriate form. Modified the
Windows allocator to only use guard pages for array-style allocations,
allowing us to enable them once again in debug builds. [Aaron Giles]
Created new static class driver_list to wrap accesses to the list of
available drivers. Improved speed of driver lookups by relying on the
presorting done by makelist. [Aaron Giles]
Created helper class driver_enumerator as a helper for iterating through
the list of drivers. This class supports basic filtering and iteration,
and also serves as a temporary cache of machine_configs. [Aaron Giles]
Created cli_frontend object to wrap all the CLI handling code in
clifront.c. Updated/simplified all the code to take advantage of the
driver_enumerator. [Aaron Giles]
Created media_auditor object to wrap all the auditing functions in
audit.c. Updated all users to the new interface. Note that the new
auditing mechanism is slightly out of sync with the romload code in
terms of finding ROMs owned by devices, so it may mis-report some
issues until the new ROM loading code is in. [Aaron Giles]
Added concept of a per-device searchpath. For most devices, their
searchpath is just the short name of the device. For driver_devices, the
searchpath is driver[;parent[;bios]]. This searchpath will eventually be
used by the rom loader to find ROMs. For now it is used by the media
auditor only. [Aaron Giles]
Created info_xml_creator object to wrap all the info generation functions
in info.c. Converted the file to C++ and cleaned up the input processing
code. [Aaron Giles]
(not for whatsnew ... Known issues: auditing of CHDs appears busted, and
debug builds report unfreed memory if you use the built-in game picker)
Remove redundant machine items from address_space and device_t.
Neither machine nor m_machine are directly accessible anymore.
Instead a new getter machine() is available which returns a
machine reference. So:
space->machine->xxx ==> space->machine().xxx
device->machine->yyy ==> device->machine().yyy
Globally changed all running_machine pointers to running_machine
references. Any function/method that takes a running_machine takes
it as a required parameter (1 or 2 exceptions). Being consistent
here gets rid of a lot of odd &machine or *machine, but it does
mean a very large bulk change across the project.
Structs which have a running_machine * now have that variable
renamed to m_machine, and now have a shiny new machine() method
that works like the space and device methods above. Since most of
these are things that should eventually be devices anyway, consider
this a step in that direction.
98% of the update was done with regex searches. The changes are
architected such that the compiler will catch the remaining
errors:
// find things that use an embedded machine directly and replace
// with a machine() getter call
S: ->machine->
R: ->machine\(\)\.
// do the same if via a reference
S: \.machine->
R: \.machine\(\)\.
// convert function parameters to running_machine &
S: running_machine \*machine([^;])
R: running_machine \&machine\1
// replace machine-> with machine.
S: machine->
R: machine\.
// replace &machine() with machine()
S: \&([()->a-z0-9_]+machine\(\))
R: \1
// sanity check: look for this used as a cast
(running_machine &)
// and change to this:
*(running_machine *)
to private member variables with accessors:
machine->m_respool ==> machine->respool()
machine->config ==> machine->config()
machine->gamedrv ==> machine->system()
machine->m_regionlist ==> machine->first_region()
machine->sample_rate ==> machine->sample_rate()
Also converted internal lists to use simple_list.
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]
Out of whatsnew: I've surely screwed up some stuff, though I have
smoke tested a bunch of things. Let me know if you hit anything odd.
Also I know this change will impact the WINUI stuff, please let me
know if there are issues. All the functionality necessary should
still be present. If it's not obvious, please talk to me before
adding stuff to the core_options class.
to pass a core_options object to the constructor, along with
a search path. This required pushing either a running_machine
or a core_options through some code that wasn't previously
ready to handle it. emu_files can be reused over multiple
open/close sessions, and a lot of core code cleaned up
nicely as things were converted to them.
Also created a file_enumerator class for iterating over files
in a searchpath. This replaces the old mame_openpath functions.
Changed machine->options() to return a reference.
Removed public nvram_open() and fixed jchan/kaneko16 to
stop directly saving NVRAM.
Removed most of the mame_options() calls; this will soon go
away entirely, so don't add any more.
Added core_options to device_validity_check() so they can be
used to validate things.
- Rewritten some checks to be runtime instead of compile dependent
- Added winmenu.c and "menu" option in windows build
- winmenu.c provide just dummy implementation, and makes linking with actual menu implementation easier.
Yes, it is intentional that the x86/x64 backends compile everywhere.
Backends are now derived from drcbe_interface and implement several
required overrides.
x86emit.h now uses namespaces so that the x86/x64 emitters can co-exist.
New file uml.h/uml.c actually describes the UML language, separating
out several concepts from drcuml.c.
Lots of other changes/fixes.
by preceding it with "0x". This allows F4 to work properly, for
example, on the 68000 stepping to address a6, which also happens
to be a register name.
if it owns a given font (based on the name), and if it does, it is
responsible for generating bitmaps on the fly as characters are requested.
Added new option -uifont to specify the UI font. It can be set to a filename,
in which case a BDF font will be loaded. It can also be set to a font name
(assuming the OSD support is present), in which case the OSD font by that
name is used. The default value is 'default' which can be used by the OSD
to substitute a default font or by the OSD, which will default to ui.bdf
as before. In all cases, it falls back to the built-in font by default if
none of the previous options works.
On Windows, the OSD will default to Tahoma as the font name. Also on
Windows, font names can be specified with [b] to indicate bold or [i] to
indicate italic.
module osdepend.c with default empty implementations. Changed
mame_execute() and cli_execute() to accept a reference to an
osd_interface which is provided by the caller.
Updated SDL and Windows OSD to create an osd_interface-derived
class and moved their OSD callbacks to be members.
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.
Moved -effect implementation out of OSD code and into core since
the implementations were identical across Windows/SDL and implemented
in the core itself.
Log: Added preliminary support for saving debugger window locations. [Andrew Gardner]
(Notes)
* I only save the values for the SDL debugger for now.
* There is no loading of these values yet, but if this patch is confirmed good,
loading should be relatively straightforward to add.
* There is a slight chance this might not compile on OSes other than linux.
I will be available via e-mail for the next 10 hours and will assist
with any compilation problems if they occur.
* The patch seems like the "right way" to do things, but if I am doing anything
suspect, please feel free to make suggestions and corrections.
devices. Debugger now creates one for each device. C++-ified most
debugger operations to hang off the debugging class, and updated
most callers. This still needs a little cleanup, but it fixes most
issues introduced when the CPUs were moved to their own devices.
Got rid of cpu_count, cpu_first, cpu_next, etc. as they were badly
broken. Also removed cpu_is_executing, cpu_is_suspended,
cpu_get_local_time, and cpu_abort_timeslice.
Some minor name changes:
state_value() -> state()
state_set_value() -> set_state()
DECLARE_LEGACY_CPU_DEVICE and DEFINE_LEGACY_CPU_DEVICE. Changed CPUs
to be their own device types, rather than all of type CPU with a
special internal subtype. Note that as part of this process I removed
the CPU_ prefix from the ALL-CAPS device name, so CPU_Z80 is just
plain old Z80 now. This required changing a couple of names like
8080 to I8080 so that there was an alphabetic first character.
Added memory interfaces to the list of fast-access interfaces. To do
this properly I had to add a separate method to devices which is
called immediately after construction, when it is possible to perform
dynamic_casts on fully-constructed objects. (This is just internal,
no changes necessary to the devices themselves.)
Some additional notes:
* SH2 and SH4 had typedefs that conflicted with their CPU_-less names
so I bulk renamed to structures to sh2_state and sh4_state; RB, feel
free to choose alternate names if you don't like 'em
* SCSP was caught doing something to the 3rd indexed CPU. Since several
systems that use SCSP don't even have 3 CPUs, I had no idea what
this was supposed to do, so I changed to it reference "audiocpu"
assuming that stv was the assumed target. This is really gross and
should be a configuration parameter, not a hard-coded assumption.
* created dynamic_bind<> template class to handle dynamically binding to
optionally-supported functions
* wrapped stack walking code in a class
* wrapped symbol lookup code in a class
* added support for parsing objdump-produced symbol dumps which include
non-global functions for much better stack dumps and profiling in gcc builds
Also: modified makefile for win32 targets to automatically run objdump and
produce a .sym file if SYMBOLS is enabled.
- always available now, just specify -profile <n> to enable it
- supports stack walking to uniquely identify call chains; the <n> parameter
to the -profile option specifies how deep to go
- automatically turns off throttling and multithreading, and sets the number of
processors available to 1 (since we only sample the main thread)
- output now uses the common symbol lookup, which actually uses the PDB for
MSVC builds and gives excellent results (may eventually figure out how to
extract gcc symbols someday)
- the top 30 unique call chains are output
running_machine definition and implementation.
Moved global machine-level operations and accessors into methods on the
running_machine class. For the most part, this doesn't affect drivers
except for a few occasional bits:
mame_get_phase() == machine->phase()
add_reset_callback() == machine->add_notifier(MACHINE_NOTIFY_RESET, ...)
add_exit_callback() == machine->add_notifier(MACHINE_NOTIFY_EXIT, ...)
mame_get_base_datetime() == machine->base_datetime()
mame_get_current_datetime() == machine->current_datetime()
Cleaned up the region_info class, removing most global region accessors
except for memory_region() and memory_region_length(). Again, this doesn't
generally affect drivers.

known at construction time, a generic name can be specified and then
overridden later once the configuration is complete.

Also:

NOTE: This is a major internal change to the way devices are handled in
MAME. There is a small impact on drivers, but the bulk of the changes are
to the devices themselves. Full documentation on the new device handling
is in progress at http://mamedev.org/devwiki/index.php/MAME_Device_Basics
Defined two new casting helpers: [Aaron Giles]
downcast<type>(value) should be used for safe and efficient downcasting
from a base class to a derived class. It wraps static_cast<> by adding
an assert that a matching dynamic_cast<> returns the same result in
debug builds.
crosscast<type>(value) should be used for safe casting from one type to
another in multiple inheritance scenarios. It compiles to a
dynamic_cast<> plus an assert on the result. Since it does not optimize
down to static_cast<>, you should prefer downcast<> over crosscast<>
when you can.
Redefined running_device to be a proper C++ class (now called device_t).
Same for device_config (still called device_config). All devices and
device_configs must now be derived from these base classes. This means
each device type now has a pair of its own unique classes that describe
the device. Drivers are encouraged to use the specific device types
instead of the generic running_device or device_t classes. Drivers that
have a state class defined in their header file are encouraged to use
initializers off the constructor to locate devices. [Aaron Giles]
Removed the following fields from the device and device configuration
classes as they never were necessary or provided any use: device class,
device family, source file, version, credits. [Aaron Giles]
Added templatized variant of machine->device() which performs a downcast
as part of the device fetch. Thus machine->device<timer_device>("timer")
will locate a device named "timer", downcast it to a timer_device, and
assert if the downcast fails. [Aaron Giles]
Removed most publically accessible members of running_device/device_t in
favor of inline accessor functions. The only remaining public member is
machine. Thus all references to device->type are now device->type(), etc.
[Aaron Giles]
Created a number of device interface classes which are designed to be mix-
ins for the device classes, providing specific extended functionality and
information. There are standard interface classes for sound, execution,
state, nvram, memory, and disassembly. Devices can opt into 0 or more of
these classes. [Aaron Giles]
Converted the classic CPU device to a standard device that uses the
execution, state, memory, and disassembly interfaces. Used this new class
(cpu_device) to implement the existing CPU device interface. In the future
it will be possible to convert each CPU core to its own device type, but
for now they are still all CPU devices with a cpu_type() that specifies
exactly which kind of CPU. [Aaron Giles]
Created a new header devlegcy.h which wraps the old device interface using
some special template classes. To use these with an existing device,
simply remove from the device header the DEVICE_GET_INFO() declaration and
the #define mapping the ALL_CAPS name to the DEVICE_GET_INFO. In their
place #include "devlegcy.h" and use the DECLARE_LEGACY_DEVICE() macro.
In addition, there is a DECLARE_LEGACY_SOUND_DEVICE() macro for wrapping
existing sound devices into new-style devices, and a
DECLARE_LEGACY_NVRAM_DEVICE() for wrapping NVRAM devices. Also moved the
token and inline_config members to the legacy device class, as these are
not used in modern devices. [Aaron Giles]
Converted the standard base devices (VIDEO_SCREEN, SPEAKER, and TIMER)
from legacy devices to the new C++ style. Also renamed VIDEO_SCREEN to
simply SCREEN. The various global functions that were previously used to
access information or modify the state of these devices are now replaced
by methods on the device classes. Specifically:
video_screen_configure() == screen->configure()
video_screen_set_visarea() == screen->set_visible_area()
video_screen_update_partial() == screen->update_partial()
video_screen_update_now() == screen->update_now()
video_screen_get_vpos() == screen->vpos()
video_screen_get_hpos() == screen->hpos()
video_screen_get_vblank() == screen->vblank()
video_screen_get_hblank() == screen->hblank()
video_screen_get_width() == screen->width()
video_screen_get_height() == screen->height()
video_screen_get_visible_area() == screen->visible_area()
video_screen_get_time_until_pos() == screen->time_until_pos()
video_screen_get_time_until_vblank_start() ==
screen->time_until_vblank_start()
video_screen_get_time_until_vblank_end() ==
screen->time_until_vblank_end()
video_screen_get_time_until_update() == screen->time_until_update()
video_screen_get_scan_period() == screen->scan_period()
video_screen_get_frame_period() == screen->frame_period()
video_screen_get_frame_number() == screen->frame_number()
timer_device_adjust_oneshot() == timer->adjust()
timer_device_adjust_periodic() == timer->adjust()
timer_device_reset() == timer->reset()
timer_device_enable() == timer->enable()
timer_device_enabled() == timer->enabled()
timer_device_get_param() == timer->param()
timer_device_set_param() == timer->set_param()
timer_device_get_ptr() == timer->get_ptr()
timer_device_set_ptr() == timer->set_ptr()
timer_device_timeelapsed() == timer->time_elapsed()
timer_device_timeleft() == timer->time_left()
timer_device_starttime() == timer->start_time()
timer_device_firetime() == timer->fire_time()
Updated all drivers that use the above functions to fetch the specific
device type (timer_device or screen_device) and call the appropriate
method. [Aaron Giles]
Changed machine->primary_screen and the 'screen' parameter to VIDEO_UPDATE
to specifically pass in a screen_device object. [Aaron Giles]
Defined a new custom interface for the Z80 daisy chain. This interface
behaves like the standard interfaces, and can be added to any device that
implements the Z80 daisy chain behavior. Converted all existing Z80 daisy
chain devices to new-style devices that inherit this interface.
[Aaron Giles]
Changed the way CPU state tables are built up. Previously, these were data
structures defined by a CPU core which described all the registers and how
to output them. This functionality is now part of the state interface and
is implemented via the device_state_entry class. Updated all CPU cores
which were using the old data structure to use the new form. The syntax is
currently awkward, but will be cleaner for CPUs that are native new
devices. [Aaron Giles]
Converted the okim6295 and eeprom devices to the new model. These were
necessary because they both require multiple interfaces to operate and it
didn't make sense to create legacy device templates for these single cases.
(okim6295 needs the sound interface and the memory interface, while eeprom
requires both the nvram and memory interfaces). [Aaron Giles]
Changed parameters in a few callback functions from pointers to references
in situations where they are guaranteed to never be NULL. [Aaron Giles]
Removed MDRV_CPU_FLAGS() which was only used for disabling a CPU. Changed
it to MDRV_DEVICE_DISABLE() instead. Updated drivers. [Aaron Giles]
Reorganized the token parsing for machine configurations. The core parsing
code knows how to create/replace/remove devices, but all device token
parsing is now handled in the device_config class, which in turn will make
use of any interface classes or device-specific token handling for custom
token processing. [Aaron Giles]
Moved many validity checks out of validity.c and into the device interface
classes. For example, address space validation is now part of the memory
interface class. [Aaron Giles]
Consolidated address space parameters (bus width, endianness, etc.) into
a single address_space_config class. Updated all code that queried for
address space parameters to use the new mechanism. [Aaron Giles]
While at it, I also associated ESC to Menu bar toggling when in newui (like many other emulators for Windows), given that user would quit MESS with File > Exit in the menu bar.
split.c: made the "split" return the actual result instead of just 0. [Oliver Stöneberg]
clifront.c: made the identation of the CPU device in -listdevices the same like the others [Oliver Stöneberg]
i386.c: gave some fatalerror() calls in the i386 proper messages [Oliver Stöneberg]
ssem.c: fixed compilation of SSEM core with SSEM_DISASM_ON_UNIMPL [Oliver Stöneberg]
srcclean.c: small wording change in the srcclean summary [Oliver Stöneberg]
sdl/window.c: fixed a potential memory leak in sdlwindow_video_window_create() [Oliver Stöneberg]
- removed ui_use_new_ui check used by MESS code
- moved ui_mess_handler_ingame call in proper place, so device UI callbacks works again
- removed toggle of menu bar (MESS related)
Replaced all occurrences of OPTION_DEBUG in src/osd/* by checking machine->debug_flags
Replaced all occurrences of DEBUG_FLAG_ENABLED in src/osd/* by DEBUG_FLAG_OSD_ENABLED
For the time being, DEBUG_FLAG_OSD_ENABLED is default (set in mame.c)

is now separate from runtime device state. I have larger plans
for devices, so there is some temporary scaffolding to hold
everything together, but this first step does separate things
out.
There is a new class 'running_device' which represents the
state of a live device. A list of these running_devices sits
in machine->devicelist and is created when a running_machine
is instantiated.
To access the configuration state, use device->baseconfig()
which returns a reference to the configuration.
The list of running_devices in machine->devicelist has a 1:1
correspondance with the list of device configurations in
machine->config->devicelist, and most navigation options work
equally on either (scanning by class, type, etc.)
For the most part, drivers will now deal with running_device
objects instead of const device_config objects. In fact, in
order to do this patch, I did the following global search &
replace:
const device_config -> running_device
device->static_config -> device->baseconfig().static_config
device->inline_config -> device->baseconfig().inline_config
and then fixed up the compiler errors that fell out.
Some specifics:
Removed device_get_info_* functions and replaced them with
methods called get_config_*.
Added methods for get_runtime_* to access runtime state from
the running_device.
DEVICE_GET_INFO callbacks are only passed a device_config *.
This means they have no access to the token or runtime state
at all. For most cases this is fine.
Added new DEVICE_GET_RUNTIME_INFO callback that is passed
the running_device for accessing data that is live at runtime.
In the future this will go away to make room for a cleaner
mechanism.
Cleaned up the handoff of memory regions from the memory
subsystem to the devices.
extension).
Improved stack walking on crash in Windows. Now using StackWalk64 to
do the stack walk, resulting in cleaner logs. Also will try to use
system function to look up symbol and source/line information if
present. End results:
- 32-bit gcc: parses symbol info from map file as before (this would
work better if we could coax gcc into outputting static functions in
the map)
- 64-bit gcc: has runtime issue that causes the exception handler to
not be invoked. Will work with mingw folks on it.
- 32/64-bit MSVC: nice stack dumps with symbol and source/line info,
if the PDB file is present. If not, falls back to the MAP file.
- Created new central header "emu.h"; this should be included
by pretty much any driver or device as the first include. This
file in turn includes pretty much everything a driver or device
will need, minus any other devices it references. Note that
emu.h should *never* be included by another header file.
- Updated all files in the core (src/emu) to use emu.h.
- Removed a ton of redundant and poorly-tracked header includes
from within other header files.
- Temporarily changed driver.h to map to emu.h until we update
files outside of the core.
Added class wrapper around tagmap so it can be directly included
and accessed within objects that need it. Updated all users to
embed tagmap objects and changed them to call through the class.
Added nicer functions for finding devices, ports, and regions in
a machine:
machine->device("tag") -- return the named device, or NULL
machine->port("tag") -- return the named port, or NULL
machine->region("tag"[, &length[, &flags]]) -- return the
named region and optionally its length and flags
Made the device tag an astring. This required touching a lot of
code that printed the device to explicitly fetch the C-string
from it. (Thank you gcc for flagging that issue!)
osd_free(). They take the same parameters as malloc() and free().
Renamed mamecore.h -> emucore.h.
New C++-aware memory manager, implemented in emualloc.*. This is a
simple manager that allows you to add any type of object to a
resource pool. Most commonly, allocated objects are added, and so
a set of allocation macros is provided to allow you to manage
objects in a particular pool:
pool_alloc(p, t) = allocate object of type 't' and add to pool 'p'
pool_alloc_clear(p, t) = same as above, but clear the memory first
pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type
't' and add to pool 'p'
pool_alloc_array_clear(p, t, c) = same, but with clearing
pool_free(p, v) = free object 'v' and remove it from the pool
Note that pool_alloc[_clear] is roughly equivalent to "new t" and
pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also
note that pool_free works for single objects and arrays.
There is a single global_resource_pool defined which should be used
for any global allocations. It has equivalent macros to the pool_*
macros above that automatically target the global pool.
In addition, the memory module defines global new/delete overrides
that access file and line number parameters so that allocations can
be tracked. Currently this tracking is only done if MAME_DEBUG is
enabled. In debug builds, any unfreed memory will be printed at
the end of the session.
emualloc.h also has #defines to disable malloc/free/realloc/calloc.
Since emualloc.h is included by emucore.h, this means pretty much
all code within the emulator is forced to use the new allocators.
Although straight new/delete do work, their use is discouraged, as
any allocations made with them will not be tracked.
Changed the familar auto_alloc_* macros to map to the resource pool
model described above. The running_machine is now a class and contains
a resource pool which is automatically destructed upon deletion. If
you are a driver writer, all your allocations should be done with
auto_alloc_*.
Changed all drivers and files in the core using malloc/realloc or the
old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros
instead, or the global_alloc_* macros if necessary.
Added simple C++ wrappers for astring and bitmap_t, as these need
proper constructors/destructors to be used for auto_alloc_astring and
auto_alloc_bitmap.
Removed references to the winalloc prefix file. Most of its
functionality has moved into the core, save for the guard page
allocations, which are now implemented in osd_alloc and osd_free.
- Changed INLINE to map to "static inline"
- (Windows only) Made -static-libgcc standard for both 32-bit and 64-bit
- (Windows only) Some fixes for MSVC builds
1. Removed CPP_COMPILE option. All files (except expat and zlib)
are now compiled as C++ by default. For now, imagine nothing has
changed. The goal is not to go hog-wild with C++isms, but to
leverage it where it makes the most sense.
2. Mapped INLINE to plain old C++ inline now, fixing several
cases where this was problematic.
3. Marked global const structures explicitly extern since consts
are locally-scoped by default in C++.
4. Added new 'default' make target which just builds the emulator.
Use 'make all' to build everything including the tools.
5. 64-bit builds now get a '64' suffix on them. We might want to
just make this true for Windows builds, but it's on for everyone
at the moment.
6. (Windows) Removed UNICODE option. UNICODE is enabled by default
on all Windows builds now. The 32-bit version links against
libunicows.a for continued Win9x compatibility.
7. (Windows) Removed hacks surrounding unicode handling of main().
They are no longer necessary with the new tools.

Subject: Stack Crawl
To: submit@mamedev.org
This patch enables the stack crawl on windows platforms again (bug
3583).
-numprocessors <auto|value>
Specify the number of processors to use for work queues. Specifying
"auto" will use the value reported by the system or environment
variable OSDPROCESSORS. To avoid abuse, this value is internally limited
to 4 times the number of processors reported by the system.
The default is "auto".
Types are pretty much unified now.
Multiply operations are handled by eminline.h.
Divide operations were just silly in macros.
64/32-bit combination/extraction macros moved to osdcomm.h and renamed.
Also fixed compile errors in recent 68k changes.

This update changes the way we handle memory allocation. Rather
than allocating in terms of bytes, allocations are now done in
terms of objects. This is done via new set of macros that replace
the malloc_or_die() macro:
alloc_or_die(t) - allocate memory for an object of type 't'
alloc_array_or_die(t,c) - allocate memory for an array of 'c' objects of type 't'
alloc_clear_or_die(t) - same as alloc_or_die but memset's the memory to 0
alloc_array_clear_or_die(t,c) - same as alloc_array_or_die but memset's the memory to 0
All original callers of malloc_or_die have been updated to call these
new macros. If you just need an array of bytes, you can use
alloc_array_or_die(UINT8, numbytes).
Made a similar change to the auto_* allocation macros. In addition,
added 'machine' as a required parameter to the auto-allocation macros,
as the resource pools will eventually be owned by the machine object.
The new macros are:
auto_alloc(m,t) - allocate memory for an object of type 't'
auto_alloc_array(m,t,c) - allocate memory for an array of 'c' objects of type 't'
auto_alloc_clear(m,t) - allocate and memset
auto_alloc_array_clear(m,t,c) - allocate and memset
All original calls or auto_malloc have been updated to use the new
macros. In addition, auto_realloc(), auto_strdup(), auto_astring_alloc(),
and auto_bitmap_alloc() have been updated to take a machine parameter.
Changed validity check allocations to not rely on auto_alloc* anymore
because they are not done in the context of a machine.
One final change that is included is the removal of SMH_BANKn macros.
Just use SMH_BANK(n) instead, which is what the previous macros mapped
to anyhow.
