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

Fixed an annoying inconsistency between memory_share and memory_region:
the width() method of the former returned the width in bits (8, 16, 32 or 64)
while the width() method of the latter returned the width in bytes
(1, 2, 4 or 8). Now both classes have a bitwidth() method and a bytewidth()
method. Updated all callers to use whichever one was more appropriate.
Removed the implicit-cast-to-any-integer-pointer ability of memory_regions,
which was rather unsafe (if you weren't careful with your * operators and
casts it was easy to accidentally get a pointer to the memory_region object
itself instead of to the data, with no warning from the compiler... or at
least I kept doing it) Updated all devices and drivers that were accessing
regions that way to use a region_ptr_finder when possible, and otherwise to
call base() explicitly.

[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):

namely, with this change the emulator displays first a "Loading Game N%" while loading MAME game or MESS system roms,
then it switches to "Loading Software %N" while loading from softlist (this also applies to Megatech, ST-V and NeoGeo lists in MAME)
I'm not completely happy with passing a "from_list" boolean to modify the behavior, but I have found no better solution.
If you find any, please be my guest and replace this solution with yours.

entries. nw.
previously, loading from softlist was using the bios romsize as totalsize to load, explaining both the erratic
percentage values in systems like AES and the totalsize = 0 error in NES and other bios-less systems, which
was requiring a special workaround.
handling is still not perfect (e.g I think that first the bios is loaded and counter goes to 100%, then the cart
is loaded and the count restarts from 0%, so it would be better to have a separate message for the softlist
loading, but I need to study in depth the code before such a change), but it's definitely better than having
AES carts loading up to 12575% or NES skipping completely the soft percentage due to totalsize =0...

memory_region management into the memory manager instead
of directly in the machine. Hid the global region method;
now all regions must be looked up relative to a device.
If you're a member function, you can just use memregion("tag")
directly. If you're a global function or a device referencing
global regions, use machine().root_device().memregion("tag")
to look up regions relative to the root.
S&R to convert all references:
machine([()]*)\.region
machine\1\.root_device\(\).subregion
Then remove redundant machine().root_device() within src/mame:
([ \t])machine\(\)\.root_device\(\)\.
\1
And use state->memregion() if we have a state variable present:
(state *= *[^;]+driver_data[^}]+)([^ \t]*)machine[()]*\.root_device\(\)\.
\1state->
Finally some cleanup:
screen.state->
state->
device->state->
state->
space->state->
state->
And a few hand-tweaks.

a best-effort attempt so that things like CRC(1) SHA1(1) can
be used to force reporting of proper checksums.

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.
