integer value, regions are now referred to by a region class and
a region tag. The class specifies the type of region (one of CPU,
gfx, sound, user, disk, prom, pld) while the tag uniquely specifies
the region. This change required updating all the ROM region
definitions in the project to specify the class/tag instead of
region number.
Updated the core memory_region_* functions to accept a class/tag
pair. Added new memory_region_next() function to allow for iteration
over all memory regions of a given class. Added new function
memory_region_class_name() to return the name for a given CPU
memory region class.
Changed the auto-binding behavior of CPU regions. Previously, the
first CPU would auto-bind to REGION_CPU1 (that is, any ROM references
would automatically assume that they lived in the corresponding
region). Now, each CPU automatically binds to the RGNCLASS_CPU region
with the same tag as the CPU itself. This behavior required ensuring
that all previous REGION_CPU* regions were changed to RGNCLASS_CPU
with the same tag as the CPU.
Introduced a new auto-binding mechanism for sound cores. This works
similarly to the CPU binding. Each sound core that requires a memory
region now auto-binds to the RGNCLASS_SOUND with the same tag as the
sound core. In almost all cases, this allowed for the removal of the
explicit region item in the sound configuration, which in turn
allowed for many sound configurations to removed altogether.
Updated the expression engine's memory reference behavior. A recent
update expanded the scope of memory references to allow for referencing
data in non-active CPU spaces, in memory regions, and in EEPROMs.
However, this previous update required an index, which is no longer
appropriate for regions and will become increasingly less appropriate
for CPUs over time. Instead, a new syntax is supported, of the form:
"[tag.][space]size@addr", where 'tag' is an optional tag for the CPU
or memory region you wish to access, followed by a period as a
separator; 'space' is the memory address space or region class you
wish to access (p/d/i for program/data/I/O spaces; o for opcode space;
r for direct RAM; c/u/g/s for CPU/user/gfx/sound regions; e for
EEPROMs); and 'size' is the usual b/w/d/q for byte/word/dword/qword.
Cleaned up ROM definition flags and removed some ugly hacks that had
existed previously. Expanded to support up to 256 BIOSes. Updated
ROM_COPY to support specifying class/tag for the source region.
Updated the address map AM_REGION macro to support specifying a
class/tag for the region.
Updated debugger windows to display the CPU and region tags where
appropriate.
Updated -listxml to output region class and tag for each ROM entry.
* Input ports are now maintained hierarchically. At the top
level are input ports, which contain a list of fields. Each
field represents one or more bits of the port. Certain fields
such as DIP switches and configuration switches contain a
list of settings, which can be selected. DIP switch fields
can also contain a list of DIP switch locations.
* Normalized behavior of port overrides (via PORT_INCLUDE or
by defining multiple overlapping bits). All fields within a
port are kept in strict increasing bit order, so altered DIP
switches are now kept in the appropriate order. This addresses
MAMETesters bug 01671.
* Live port state is now fully separate from configured
state. This is manifested in a similar way to devices, where
a const list of ports can be managed either offline or live.
Each port has a pointer to an opaque set of live state which
is NULL when offline or valid when live. Each port also has
a running_machine * which is also NULL when offline.
* Because of this new arrangement, the conversion from tokens
to a list of ports now requires reasonably complex memory
allocation, so these port lists must be explicitly allocated
and freed (they are not mantained by automatic resource
allocation).
* Custom and changed callbacks now take a pointer to a field
config instead of a running machine. This provides more
information about what field triggered the change notification.
The machine can be found by referenced field->port->machine.
* The inptport.c module has been cleaned up and many
ambiguities resolved. Most of this is internal, though it did
result in osd_customize_inputport_list() being changed to
osd_customize_input_type_list(). The parameter to this function
is now a linked list instead of an array, and the structures
referenced have been reorganized somewhat.
* Updated config.c to pass machine parameters to its callbacks.
* Updated validity checks, XML output, and UI system to handle
the new structures.
* Moved large table of default input settings to a separate
include file inpttype.h.
* Removed gross hacks in trackfld and hyperspt NVRAM. These
may be broken as a result.
to write RGB bitmaps. Unfortunately, the only option is fully
uncompressed, which means the resulting AVIs are *HUGE* and
may not play correctly in realtime due to high data rate. The
intention is that these uncompressed AVIs are post-processed
by other utilities to compress the video and produce a
realtime playable result.
Added new command-line option -aviwrite which works just like
-mngwrite, except it produces AVIs and streams sound to them.
Updated documentation accordingly.
Shift+F12 still produces MNGs for now, though this might change
in the future.
Modified fileio.c to retain the full pathname to the file so
that it can be queried while the file is open.
Subject: [patch] Remove more Machine globals, #include "deprecat.h"
Hi mamedev,
The attached patch goes through and converts a number of Machine
globals to machine locals, and then removes #include "deprecat.h" if
appropriate. The script that generated it is included, since the
patch itself is rather large and would have been time consuming to
produce otherwise.
The script doesn't convert cases of Machine that aren't in common
macros. I'll try to tackle those later if someone doesn't beat me to
it.

Subject: Machine -> machine cleanups
This patch changes "Machine" to "machine", when the runnin-machine
parameter is already available. In some cases I could even remove the
dprecat.h.
I will look for some occurances where it can be easily changed and
afterward take a step at adding the running_machine parameter in a
few places.
Added DEVINFO_INT_TOKEN_BYTES, which is queried before device
startup. It should return the size of the structure that will
be hung off of device->token. It must not return 0.
Changed the core device interface to allocate and zero a block
of memory the size of DEVINFO_INT_TOKEN_BYTES before calling
device_start. The pointer to this memory is already attached
to device->token at the time device_start is called.
The primary motivation for this is to allow the device_start
function to make internal calls and pass the device_config *
around as if the object were fully constructed. Since the token
is used to indicate whether or not a device is live, this makes
the device "live" at the time device_start is called rather
than after it completes.
than tokens and individual bits to the device callbacks. Updated
all existing devices accordingly.
Removed machine from the parameters of some of the device_get_info
and device_set_info calls because that information is stored
with the device now.
to use the macros.
Added the concept of device classes. Devices specify their class
in their get_info function. Classes can be used to walk through
devices at a more general level than their type. Functions have
been added to iterate through devices by class just as you can
by type.
Removed some unused fields from device_config.
constructors to tokenized lists. For the most part
this is a non-invasive change, except for those drivers
using MDRV_WATCHDOG_TIME_INIT. In order to allow for
tokenization of attotimes, a set of new macros is
provided called UINT64_ATTOTIME_IN_x() which follows the
same pattern as ATTOTIME_IN_x() but packs the attotime
down into a single 64-bit value for easier tokenization.
Separated MDRV_DEVICE_CONFIG_DATA into 32-bit and 64-bit
versions. Added floating-point versions with configurable
resolutions.
Fixed several errors in the machine drivers which were
caught by the additional checks now done in the machine
config detokenization code.
Converted speakers into devices. Machine->config no
longer houses an array of speakers; instead they are
iterated through using the new macros (defined in sound.h)
speaker_output_first() and speaker_output_next(). Updated
all relevant code to do this.
Improved game info display with multiple screens. Fixed
bug which caused all screens to display equally.
Added typedefs for all the machine config callback
functions at the top of driver.h.
The idea is to create extra work if a driver wants to use these and hopefully
gives an incentive to look for an alternate solution
- Added #include of deprecat.h that rely on these contructs
- Removed a bunch of unneccassary #include's from these files
- removed years from copyright notices
- removed redundant (c) from copyright notices
- updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
The attached patch adjusts most conditional logging in MAME to use the
idiom "do { if (VERBOSE) logerror x; } while (0)". This has the
benefit that the compiler checks the syntax of the logging even in the
case it will be eliminated, and in fact a number of cases here needed
adjustments to compile because of this.
