Per-game parameters are (tag, value) pairs that follow the same tag
structure than everything else. They're added within a ROM section
with ROM_PARAMETER(tag, value). You look them up through the device
method parameter(tag) which returns the string, or "" if not present.
A *lot* of drivers can benefit from that stuff. It should kill most
game-name keyed tables, and the alternative approach of
bazillon-of-driver-inits.
Possible evolutions, if someone wants to do it:
- output them in -listxml
- push the softlist parameters present in the xml through that
- maybe allow to change/set them through the command line

[Aaron Giles]
* these classes now no longer take a resource_pool; everything is
managed globally -- this means that objects added to lists must be
allocated with global_alloc
* added new auto_pointer<> template which wraps a pointer and auto-frees
it upon destruction; it also defaults to NULL so it doesn't need to
be explicitly initialized
* moved tagged_list template to tagmap.h
Redo of the low-level memory tracking system: [Aaron Giles]
* moved low-level tracking out of emu\emualloc into lib\util\corealloc
so it can be shared among all components and used by core libraries
* global_alloc and friends no longer use a resource pool to track
allocations; turns out this was a wholly redundant system that wasted
a lot of memory
* removed global_resource_pool entirely
* added global_free_array to delete arrays allocated with
global_alloc_array
* added tracking of object versus array allocation; we will now error
if you use global_free on an array, or global_free_array on an object
Added new utility helper const_string_pool which can be used to
efficiently accumulate strings that are not intended to be modified.
Used by updated makelist and software list code. [Aaron Giles]
Updated png2bdc and makelist tools to not leak memory and use more modern
techniques (no more MAX_DRIVERS in makelist, for example). [Aaron Giles]
Deprecated auto_strdup and removed all uses by way of caller-managed
astrings and the software list rewrite. [Aaron Giles]
Rewrote software list management: [Aaron Giles]
* removed the notion of a software_list that is separate from a
software_list_device; they are one and the same now
* moved several functions into device_image_interface since they really
didn't belong in the core software list class
* lots of simplification as a result of the above changes
Additional notes (no whatsnew):
Moved definition of FPTR to osdcomm.h.
Some changes happened in the OSD code to fix issues, especially regarding
freeing arrays. SDL folks may need to fix up some of these.

delete it, which you can't):

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.

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

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 *)

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.

and manages a collection of hashes, and can be built from an internal
format string which is stored with each ROM. All core instances are
cleaned up to use the new interfaces, but it's likely that hashfile
code in MESS will need an update.
Also compacted the form of the hash strings used for ROMs, and fixed
verification/hashing of non-ZIPped files.

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.

are still intact. The new state_manager class has templatized methods
for saving the various types, and through template specialization can
save more complex system types cleanly (like bitmaps and attotimes).
Added new mechanism to detect proper state save types. This is much
more strict and there will likely be some games/devices that fatalerror
at startup until they are remedied. Spot checking has caught the more
common situations.
The new state_manager is embedded directly in the running_machine,
allowing objects to register state saving in their constructors now.
Added NAME() macro which is a generalization of FUNC() and can be
used to wrap variables that are registered when directly using the
new methods as opposed to the previous macros. For example:
machine->state().save_item(NAME(global_item))
Added methods in the device_t class that implicitly register state
against the current device, making for a cleaner interface.
Just a couple of required regexes for now:
state_save_register_postload( *)\(( *)([^,;]+), *
\3->state().register_postload\1\(\2
state_save_register_presave( *)\(( *)([^,;]+), *
\3->state().register_presave\1\(\2

out of whatsnew: to avoid too much duplicate code, I implemented this as follow:
for parent, we pass a location tag "list/parentname" to search for the roms (no
changes in this case); for clones, we pass a composed location tag
"list/clonename%list/parentname" (notice the '%' separator) and then it is
open_rom_file to split it, if it finds a %, before searching for the rom.
out of whatsnew, 2: I also added the same support for cassettes and floppies (in
devimage.c), but it is still commented out because I had only a few files for testing.
as soon as I'm sure nothing gets broken, I'll enable it.

device interface. This means all ROMs are now exposed via devices,
and thus the process of enumerating ROMs gets simpler.
Changed all instances of temporarily allocating machine_config objects
to just put them on the stack for simplicity, letting the destructor
handle the cleanup work automatically.
Changed machine_config constructor to take a game_driver, from which
the machine_config constructor is obtained. This also means the
resulting machine_config holds a reference to the game_driver.
Changed running_machine constructor to no longer take a game_driver,
since the game_driver is now obtainable via the machine_config.

- 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!)

useable as a stack object. Also designed the interfaces to allow
for chaining operations. And added a casting operator to const
char * for seamless use in most functions that take plain old C
strings.
Changed all uses of astring to use the object directly on the
stack or embedded in objects instead of explicitly allocating
and deallocating it. Removed a lot of annoying memory management
code as a result.
Changed interfaces that accepted/returned an astring * to
use an astring & instead.
Removed auto_alloc_astring(machine). Use
auto_alloc(machine, astring) instead.

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.

to be working reliably.
Deprecated the ROMREGION_DISPOSE flag, as 98% of the use of it no
longer is applicable with on-the-fly decoding, and the remaining
cases are difficult to identify among the others.

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.

- added running_machine to internal structure, removed as explicit parameter
- added new function rom_file_size() to compute the size of a ROM
- removed rom_first_chunk() and rom_next_chunk() which are no longer needed
- changed progress display to be based on size of ROMs loaded, not number
- changed temporary load buffer to be dynamically allocated
- fixed reload logic to handle skipped BIOSes
Also changed rand_memory() to use a fixed seed for consistent behavior.

Updated romload to use an astring for accumulating errors (I always feared
busting that buffer with some huge romlist).

|
|
|
|

ROM_DEFAULT_BIOS("biosname") in the ROM definition. This can be
used to ensure a correct default BIOS for ROM versions that care.

now have their tags auto-prefixed with the device's tag. This allows for
multiple instances to be present. For example, the PR-8210 laserdisc player
has a CPU with a tag of "pr8210". When it is included as a device by a
driver, the driver may tag the device "laserdisc". The resulting final
CPU tag name will be "laserdisc:pr8210". Also updated the debugger
expression engine to support names with embedded colons.
Added warnings to ensure that tags used for CPUs, sound chips, regions, and
devices follow some basic rules: they should be less than 12 characters long,
be all lower-case, and only contain letters, numbers, underscores, or dots
(no spaces). This is to ensure that they can be used properly in debugger
expressions and don't get too long or unwieldy to type (even 12 chars is a
bit long).

device to provide a set of ROM regions to be loaded along with the game
ROMs. It is expected that most regions defined for devices will use the
ROMREGION_LOADBYNAME flag to enable the ROMs to live in a central location.
Added new device interface selector: DEVINFO_PTR_MACHINE_CONFIG. This allows
a device to specify a partial machine driver which is appended to the end of
the machine driver for any game using that device. The intention for this is
to allow devices which have their own BIOS logic to specify CPUs and other
characteristics common to all systems using the device.
Added new ROMREGION flag: ROMREGION_LOADBYNAME, which means that if the ROMs
in that region are not found in the usual driver files, then the name of the
region will be used as a driver filename for loading.
Extended the ldcore interface structure to allow each player type to provide
its own ROM region and partial machine driver.
Moved preliminary PR-8210 emulation code from ldplayer.c to ldpr8210.c. It
is currently disabled behind the EMULATE_PR8210_ROM compile time flag.
