-avr8: Implemented MULS, ANDI, STD Z+, LD -Z, LD Y+, LD -Y, LD -X, SWAP, ASR,
ROR, and SBIS opcodes. [MooglyGuy]
-avr8: Moved Timer 0-2 into the CPU core itself, 30x driver speedup [MooglyGuy]
-cratft.c: Fixed DAC bit order, audio now plays but is 40% too slow [Mooglyguy]
- Fixed some glitches with the SE/30's built-in video
- Added preliminary infrastructure for LC and '030-type processor-direct slots
- Support for SE/30 processor-direct slot version of RasterOps Colorboard 264
types. Created a binding_type_exception which is thrown when
a bind attempt fails due to mismatched types.
Added helper templates to driver_device to wrap legacy
device read/write handlers into driver_device member functions.
This should help move some things forward until more common
code is converted into proper devices.
Introduce new module devcb2 which contains modernized
versions of devcb. Compared to previous implementation
this one is simpler overall, trampolining calls through
a single internal set of adapter functions. The new
versions are also designed to be specified in the
machine_config rather than in structures, so they are
no longer simple POD types. Additional new/changed
features:
* reads and writes can map to delegates for line or 8/16/32/64-bit
* reads and writes can map to an I/O port
* reads can be mapped to a constant value, with or without logging
* writes can be mapped to a device's input line
* all reads/writes can have a shift, mask, and/or xor applied
* devices can opt to make the functions safe-if-NULL when resolving
* only member function types are supported
Rewrote the YM2151 interface to be fully modernized, and
removed the ym2151_interface struct in favor of inline configs
using the new devcb2 mechanism. In many cases, removed
no longer needed trampolines, instead taking advantage of
direct support for input line writes.
greatly improving performaces (e.g. Manic Miner demo went from 20% to 380%
ingame). Plus added some very preliminary softlists. [David Haywood]
(MESS) spectrum_cass.xml: added very preliminary softlist containing some
interesting test case for emulation. [David Haywood]
Remaining TODO list:
- take WP into account
- test the amstrad, implement its observational format (edsk) using
pasti as a start. Or find the legendary amstrad IPFs. Or both.
- correct read track, the implementation is completely wrong. See
previous for testing, it's only used in protections the check the
inter-sector gaps.
- shake and bake on the amstrad, protections are the best to find bugs
in a fdc
- add the scan id commands, but nothing seems to use them
- debug the 2.88M formatting which is unreliable. Fix its IDAM/DAM
gap size on formatting too (but that's not what's making it
unreliable)
- test all the systems that were hit, and fix what needs to be fixed.
Beware that multiple problems may happen:
- upd765 may be wrong
- the driver may not be working
- the hookup may be wrong/incomplete (bitrate selection and floppy
rpm in particular)
- the driver may be too limited for the new implementation (the x68k
dma device does not handle non-instant dma yet for instance)
- report invalid command when appropriate depending on the actual chip
emulated
- add the russian clones with their real names
and added a new command line option of "-viewlist" which will print out a list
of all the devices that can be viewed in human readable logic equations.
Also updated the jedutil regression test to support passing in an additional argument of "debug" to print out a detailed log. Also moved the jedutil regression test
data into separate directories composed of the device's name to make things
more organized. [Kevin Eshbach]
non-templatized helper class so that the code can live
co-located, rather than invading device.h.
Changed the read/write delegates to derive from
device_delegate. Updated the address map macros to create
these properly.
Removed remnants of the old AM_BASE/SIZE macros from the
memory system.
eventually, nes_mmc and its pieces (nes_pcb, nes_ines & nes_unif) will contain a cart slot device and allow for
things like on-cart sound chips and eeprom devices to be properly emulated
---------------------
Blankity Bank (PCP) (SYSTEM80) [TTX]
Changed FME drivers to use per-driver layouts, rather than awpvid generic ones - should make tiny builds a bit easier, and gives more opportunity to tweak for hardware specific stuff. (nw)
Made some modifications to the jedutil tool to allow the viewing of simple combinatorial jeds (adding support for registered and gals in the future) by taking a jed file and printing out human-readable equations. Changed the command line options of the jedutil tool to know take an initial argument to specify what the tool should do.
For example to convert a jed to bin the command is now:
jedutil –convert <source.jed> <dest.bin>
jedutil –convert <source.bin> <dest.jed>
To view a jed file with human-readable equations the command is
jedutil –view <source.jed> <pal type>
Added a simple regression test for the tool that just verifies that the currently known pals have the row and column fuse location mapped correctly and at the moment this tool runs under windows only.
Under the directory src/regtests/jedutil there is a Windows Script File with the name jedtest.wsf that if run from the command line with the command “cscript jedtest.wsf” will verify that a dump of the jeds in src/regtests/jedutil/jeds matches the good dumps in src/regtests/jedutil/baseline. Reference jed files created using the tool eqn2jed which is included with Opal Jr and these files are in src/regtests/jedutil/eqns.
and a sparse bitmap for tracking which areas got updated.
This allows sprites to be rendered independently to their own
bitmap and then mixed in a final step. Converted the Sega
sprite device over to this new model, and moved the mixing
steps out of the sprite implementations and into the driver-
specific video updates where it belongs. [Aaron Giles]
Added some further methods and helpers to the bitmap_t and
rectangle classes. [Aaron Giles]
Created a sega_16bit_common_base class which handles the
common Sega palette RAM mappings and open bus reads.

out of whatsnew: I also hooked up the list to the driver, even if I have no idea to which degree the system works these days (I don't know much about this machine).
out of whatsnew: the disk dumps do not come from original media, but given that no more program disks ever appeared in the past two years and that even the website which originally hosted these disks disappeared, it is definitely worth documenting them before they get lost forever...
also mame\includes\multfish.h can/must be removed from source tree coz it is not used by driver. by MetalliC (no whatsnew)

Comment: note, could still do with andreas seeing if he can find a relationship between the encryption tables we've derived from studying the
protection (used to decrypt the various blocks in the protection data
rom) and the final block in the protection data rom..
* Split segas16.h header into separate headers for each system
* Fully modernize segas16a
* Convert multiply, divide, and compare/timer chips into
modern devices
* Fix bug causing tturfu and wrestwar to hang at startup
baseboard there (most of these ones actually run quite well apart from
some moaning about reels) This board used the AY8913, the mod4 board
didn't have that, so it's a logical split point. Also some more identification / tagging etc. of other sets. From Haze (nw)
* Converted FD1089/FD1094 into proper devices, derived
from m68000. They now handle their own decryption and
memory management, so we can remove all the calls for
initialization/reset/etc. The key now lives as a 'key'
subdevice under the CPU, and the FD1089/1094 are now
specified just like any other CPU.
* Removed the horrible s16fd and s24fd files. Good riddance.
* Created a helper class for managing fd1094 decryption
caches.
* Converted the memory mapper into a new modern device
and updated the segas16b, segaorun, and segas18 drivers
to use it. Fixed ROM memory mapping so that the source
ROMs can be loaded contiguously, removing a bunch of
hacks.
* Untangled the joined segas1x_state and split the states
for each system into their own classes. Cleaned up some
implementations.
* Added support for member functions to be called as
DRIVER_INIT functions. To do this, #define
MODERN_DRIVER_INIT prior to #including "emu.h" and you
will be required to specify a class and member function
for your driver init.
* Fully modernized the segas16b and segas18 drivers.

(mpu4dealem.c) because it's a unique expansion, no point in having all
that stuff in the main state. The standard video board it's own state class too, and moved specifics to that, plus converted the scn2674 video chip to be a device (new files there too) again reducing the amount of junk in the base mpu4 state. From Haze (nw)
- Based on timeslot modelling, the implementation models gate delays in logic chips.
- Design ready to be split into a generic and a MAME implementation part.
- Design prepared to merge in discrete components from discrete.*
- Supports code based as well as external net list parsing.
Ultimately, net lists and discrete emulation should share one code base. The class design was set up to accomplish this. There is no point in having multiple 555, 7474 implementations around.
Most of the code will be moved to lib/netlist going forward to allow usage in other projects.

Put liberatr back the way it used to be.
Normalized soundlatch helper function names.
Created delegates for machine/sound/video_start/reset callbacks and
added necessary infrastructure to use them going forward.
- General update which fleshes out some of the 68307 code (not 100% correct hookups, just improved logging and enough to get us somewhere).
- Added various devices to the SC4 emulation, added a default layout showing the VFD, to which most of the earlier games will now write 'Initializing'. Timers and other devices still need to be implemented properly before they actually initialize.
- Put the actual SC4 hardware emulation in drivers/bfm_sc4h.c so that it doesn't get lost in the swamp of sets (scrolling through a file is quite hard when it's almost entirely set definitions)
and the insane 16 graphics banks scheme. Improved the Wild Witch and

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.
- The SDL team has moved from 1.3 to 2.0. At the same time, changes were made to allow SDL1.2 and SDL2.0 to coexist. All SDL2.0 include files are now in /usr/include/SDL2.
- Added sdlinc.h to avoid having tons of #ifdef .. #include in the code.
- Scalemode is no longer a per-window setting
- Fixed a bug in YUV rendering.
- Use SDL_GetClipboard (SDL2.0)
- Updated README_SDL20.txt
Currently, SDL 2.0 is only supported on *nix. Volunteers welcome.
(nw) If anyone has any suggestions on how better to sync per-scanline state than what I'm currently doing, I'd be all ears. The renderer is now pretty darn fast, but every little bit counts.

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.
test driver that (ab)uses the core to single step a CPU executing
arbitrary instructions and capturing before/after state and
tracking memory. Currently this driver is always compiled, but is
not referenced in mame.lst.
Also updated and modernized the dummy empty driver.
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.

Arcana Heart Full [Tormod, Smitdogg, The Dumping Union]
Comments from Haze: Note, I haven't marked this as a bootleg, but 75% of the rom is actually MAME ROM zips, they've clearly recycled flash chips from one of the MAME multi-boots, so I have a feeling that this might have been a 3rd party upgrade. I doubt they shipped like this from the factory, so I've added a comment to that effect because it should definitely be verified against other copies of the game at some point.

Note: extremely preliminary. No music, just sfx. No per-voice volume/panning. No attempts to optimize. Lots of hardcoding for how the CV1000 uses the chip. I will fix all of these later, but I gotta get to sleep now ;-)
A kind of MSX2 hardware on steroids...

Unknown TMS9980 Poker Game [Roberto Fresca, Team Europe]
Comment: This is mostly konami stuff.. if anybody knows the cpu on konendev please hook it up.. i think the sets are all incomplete, but unless it's missing a bios it should be possible to run the code at least.
Added missing inputs, fixing structure. Added button-
lamps support and layout to saiyukip, coin counters
and complete documented outputs to both games.
Also reworked the DIP switches structure to match
what the test mode shows, with their respective DIP
locations [Roberto Fresca]
and GFX offsets. Both sets are working properly. [Roberto Fresca]

Bingo (set 1) [Roberto Fresca, EMMA Italian Dumping Team]
Bingo (set 2) [Roberto Fresca, The Dumping Union]
- It is used by MESS side i8251 and 6551 are using it now
- Also created simple serial source devices (used by some cassette interface)
This will be optimized and rechecked after new chips are converted to use it
No whatsnew for now, but there will be info for the release.
- adds some additional skeletons BGT, Stella
- adds even more MPS sets, and basic support for what looks like something which was an earlier unknown system similar to MPS/System 80, but with different mappings etc. by Haze (no whatsnew)
- Removed LOADBYNAME, since it is deprecated by using per device rom load_software_part_region
- Created makedev tool to generate array of devices, and created lst file according to current devices usage.
- Changed listxml command to output device roms too
using one cothread for each executable device. This functionality is
strictly internal and should result in no changes in scheduling
behavior. However, it now becomes possible to exit out of a device's
execution in the midst of an instruction by calling
machine().scheduler().make_active(). Note that this is somewhat dangerous
for cores that have logic at the start of their execute loop to check for
interrupts or other conditions, as those checks will be skipped upon
resume, so consider this sort of early exiting to be highly experimental
for now. [Aaron Giles, Miodrag Milanovic, byuu]
- 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
- 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.
Part II: Artwork.
aperture.png: Based on Aaron's aperture_4x6 mask but with more prominent notching to bring out the "brick" pattern that was used on many period colour monitors, including the Commodore 1702 - which was, admittedly, not an arcade monitor, but it looks believable and can be changed.
white.png: Default 8x8 255,255,255,255 texture.
Focus: 8-sample blur that averages 7 samples around a center sample.
Phosphor: Not currently used, treated as a pass-through by drawd3d.c, but could be used to implement additional convolutions in a second pass.
Pincushion: Used (when commented in in drawd3d.c) to pincushion an entire full-screen texture but not otherwise apply any convolutions.
Post: The meat and potatoes. It does scanlines, it does aperture masking, it does dot crawl, it does chroma subsampling, it does YIQ colorspace convolution, it does RGB colorspace convolution, it does pincushioning, it walks, it talks, it does the dishes, it'll screw your wife for you, and if you don't have a wife it will find one for you, get you married to her, and screw her for you, IT IS THAT GOOD, LADIES AND GENTLEMEN.
Primary: Simple passthrough for UI and artwork.
Remove the old tokenizing helpers. Add basic classes for ports, fields,
settings, and dip locations as a first step. These will be fully cleaned
up later. Added machine() method to field to hide all the necessary
indirection. Changed custom/changed handlers into generic read/write
handlers, and added wrappers to convert them to device read/write
lines. [Aaron Giles]
MDEC is now an internal device of the PlayStation CPU [smf]
PlayStation DMA uses delegates so devices can be hooked up.
device_t::siblingdevice() uses device list on mconfig() so it can work before the machine is constructed.
moved unused console code back to mess.
Note that msm8251 would be nice to have on emu section but it depends of serial.c which needs to be rewritten in order to be useful. Also upd765 is used only by MESS and it's pain to keep it in emu since it is not yet bug free.
Converted PlayStation DMA to an internal device to the CPU core. DMA to external devices can be set in the machine config, the old calls are still there until the rest of the code is converted. [smf]
The following MAME core changes have been required to allow internal devices to be configurable by the main machine config & to work with internal memory maps.
device.machine_config_additions() are now processed as soon as the device is added, so sub devices can be configured straight away.
replacing or removing a device removes any devices owned by the device being removed, as now they are added straight away.
device_t::subdevice() uses the machine config device list instead of the machine to find the device as the machine is not created until after all the devices have been created.
devices in an internal address map are assumed to be owned by the CPU, while devices in a standard address maps are assumed to be siblings of the CPU.
A code review and regression test would be a good idea.
