address_space. Also added unaligned variants that can read
unaligned values. Rewrote the core handler as a template that
handles all cases, along with a simple unit test to verify that
everything is correct.
Updated 68k, v60, i86, and nec cores to use unaligned read/
write instead of their own stubs for handling misalinged reads.
Fixed memory management of ga2 decryption.
supporting cleaner implementations of drivers in the explicitly OO world.
Expect a follow-on of several more changes to clean up from this one, which
deliberately tried to avoid touching much driver code.
Converted address_space to a class, and moved most members behind accessor
methods, apart from space->machine and space->cpu. Removed external references
to 8le/8be/16le/16be/32le/32be/64le/64be. All external access is now done via
virtual functions read_byte()/read_word()/etc. Moved differentiation between
the endianness and the bus width internal to memory.c, and also added a new
axis to support small/large address spaces, which allows for faster lookups
on spaces smaller than 18 bits.
Provided methods for most global memory operations within the new address_space
class. These will be bulk converted in a future update, but for now there are
inline wrappers to hide this change from existing callers.
Created new module delegate.h which implements C++ delegates in a form that
works for MAME. Details are in the opening comment. Delegates allow member
functions of certain classes to be used as callbacks, which will hopefully
be the beginning of the end of fetching the driver_data field in most
callbacks. All classes that host delegates must derive from bindable_object.
Today, all devices and driver_data do implicitly via their base class.
Defined delegates for read/write handlers. The new delegates are always
passed an address_space reference, along with offset, data, and mask. Delegates
can refer to methods either in the driver_data class or in a device class.
To specify a callback in an address map, just use AM_READ_MEMBER(class, member).
In fact, all existing AM_ macros that take read/write handlers can now accept
delegates in their place. Delegates that are specified in an address map are
proto-delegates which have no object; they are bound to their object when
the corresponding address_space is created.
Added machine->m_nonspecific_space which can be passed as the required
address_space parameter to the new read/write methods in legacy situations
where the space is not provided. Eventually this can go away but we will
need it for a while yet.
Added methods to the new address_space class to dynamically install delegates
just like you can dynamically install handlers today. Delegates installed this
way must be pre-bound to their object.
Moved beathead's read/write handlers into members of beathead_state as an
example of using the new delegates. This provides examples of both static (via
an address_map) and dynamic (via install_handler calls) mapping using delegates.
Added read/write member functions to okim6295_device as an example of using
delegates to call devices. Updated audio/williams.c as a single example of
calling the device via its member function callbacks. These will be bulk
updated in a future update, and the old global callbacks removed.
Changed the DIRECT_UPDATE_CALLBACKs into delegates as well. Updated all users
to the new function format. Added methods on direct_read_data for configuring the
parameters in a standard way to make the implementation clearer.
Created a simple_list template container class for managing the common
singly-linked lists we use all over in the project.
Many other internal changes in memory.c, mostly involving restructuring the code
into proper classes.

To: submit@mamedev.org
Cc: atariace@hotmail.com
Hi mamedev,
This patch removes all global variables from seta.c, seta2.c and
ssv.c. The number of AM_BASE() macros drops by 4% from 3111 to 2989.
Note: ssv.h and seta2.h are new files.
~aa
up the definition, rather than the whole tokenizing system, which lost type
checking. Added a new module addrmap.c which implements the address map
classes, and changed the macros to call methods on the address_map and
address_map_entry classes which are strongly typed.
Fixed a few incorrectly specified memory map entries along the way. Please
double-check to make sure the behavior is expected in: twincobr.c, lordgun.c,
galaxold.c.
This change also means that since the address_maps are now constructor
functions, they are detected when not used, so a number of #ifdef UNUSED_CODE
were added around dangling address map definitions.
Also included with this change:
- removed cputag_clocks_to_attotime() and cputag_attotime_to_clocks() in
favor of just expanding the class
- same for cputag_suspend() and cputag_resume()
* Initial release.
* Preliminary memory map.
* Hooked both PIAs, but need more analysis to confirm the offsets.
* Accurate graphics and color decode.
* Added main PCB and daughterboard layouts.
* Added partial docs and diagrams about the CPU/MCU/ROMs addressing.
* Added debug and technical notes.

* Corrected the way the steering wheel is hooked up, fixing the jittery
steering in the sets with MCUs.
* Added a new layout file for the bootleg sets without MCUs (topracern and polepos2bi).
* Converted clock frequencies to crystal values from xtal.c.
* Added correct ROM names for the Namco-manufactured sets (polepos and polepos2).
* Completely removed the unused global variable polepos_gear_bit.
* Fixed a couple of bootleg ROMs that were very likely bit-rotted.
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.
like them, but it's a start. Split implementation of individual view
types out to separate files. Updated all callers.
Also:
* fixed okim6295 memory view
* changed emualloc to free resource pools from earliest to latest
so that early objects can safely clean up stuff they allocated
- moved image legacy device implementation to devimage.c
- created image.c implementation with initialization of devices/configuration for image devices, used those calls from mame.c
- some minor cleanup of legacy device and initial implementation of some calls
(no whatsnew for now, this is just for log,will put more info on final commit)
- Created legacy image device
- Moved opresolv implementation from MESS
- listmedia is option is available in MAME too
- listxml output now contains image devices
performance as a result of this change. Do not panic; report issues to the
list in the short term and I will look into them. There are probably also
some details I forgot to mention. Please ask questions if anything is not
clear.
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]

side note: the device-fied code (currently included in video/decodev.c) still needs various refinements, but I will clean it up after all the drivers have been converted.
Added driver_data struct to the following drivers: mgolf.c, minivadr.c, mosaic.c and mrdo.c
Enabled save states to mugsmash.c (everything was already saved)
- added support for arbitrary number of containers for render_target
- added command-line parameter -debug_internal (-di) to use the internal debugger when in debug mode
- internal debugger supports all views except memory view
- added "Debug" view to layout/vertical.lay to create more place for debug views in vertical games.
The colors are ugly. Font rendering needs improvement. There are no shortcut keys right now. There is still a lot of room for more improvements.
However, it works and does not depend on any ui toolkit. The interface has been designed to support displaying views programmatically e.g. from the ui.
Currently, the ui render target is used. In order to support views being displayed in separate windows further changes are needed:
- the osd layer must support creating and closing windows (render targets) on demand.
- There must be a mode for render targets where their bounds follows the window size - Currently the render target size depends on the aspect of currently selected "artwork" view.
- Render target needs a name property.
Short HowTo:
- Start MAME with "-debug -di"
- Console, register and disasm views will be shown. Place them by dragging the view on the title bar.
- Views can be resized by dragging the bottom-right yellow square.
- The view having the focus has a green background title bar.
- Hit "Tab" (IPT_UI_CONFIGURE) to show the menu.
- Console and disasm views support a very simple facility to support entering commands and addresses. Just start typing. Hit "enter" when finished.
