* OPL prep. Define FAMILY constant in register classes, and use that instead of template specialization for family-specific behaviors. Expand channel masks to 32 bits. Add is_keyon() helper.
* Made FM channel and operator mapping more flexible. Operators are now owned by the engine and can be dynamically assigned to channels. Register classes now provide a mapping between a linear set of operators and channels. The register data array is now a regular array instead of a vector.
* Minor change for consistency.
* Introduce OPL registers and create a ymopl_engine. Add support for sustain-less notes and the OPL envelope clocks (which does not divide by 3).
* Moved keycode calculations into register class. Removed unnecessary recalc in phase generator. Lined up OPL frequency, feedback, algorithm, and total level.
* Implement key scale level and OPL-specific LFO and phase handling.
* Create new YM3526 device based on new OPL. Fix keyon and sustain behaviors.
* Fix weird OPL multiple values. Clean up and further document OPL LFO.
* No busy flag on OPL, so no need to do the work. Add a right shift of 1 to the output stage to line up volume with old implementation.
* More compact way of representing key scale level values.
* Move the KSL bitswap into the registers since it's apparently fixed in OPLL and perhaps others.
* Add support for ryhthm generation in OPL. Change compute_volume to take a phase value directly, and expose operator phase.
* Fix OPL timers.
* Start LFSR with a non-zero value to ensure it actually starts generating for OPL.
* Fix silly bug in sustain logic for OPL. Fixes a lot of previously missing sounds.
* Create OPL2 engine. Add waveform support for OPL2/3 waveforms.
* Wire up YM3812 to the new OPL2 engine.
* Reset OPL timers when the mask is written as well.
* Manage rhythm key ons separately. Fixes Wardner awfulness.
* Explicitly make channel logic handle 0, 2, or 4 operators rather than checking each one for null. Also simplify the combining logic for the 2 operator case.
* Reverse bit order of LFSRs to make things a little simpler. Fix OPL LFSR so that it has its full 23-bit period.
* Change outputs along the path to arrays rather than stereo items. This allows for four channel output. Also add a constant for the number of outputs to the register class.
* Move status register bit definitions to the registers class. Generically support the IRQ bit.
* Create shared helpers for FP encode/decode/roundtrip and use them throughout. Also update TMNT to use the FP decoder.
* No need to clamp when using the roundtrip.
* Clear the EOS flag when execute is turned off on ADPCM-B. Fix combine_status in YM2608 to ignore previously set flags.
* Add missing note_select in base class. Don't add 1 to the OPL release rate.
* Move Y8950 over to new OPL engine.
* Remove old y8950, along with fmopl and ymdeltat
* Add updates prior to status reads for ADPCM systems.
* Add status_mask and irq_reset logic into the core. Clean up documentation on family-specific registers. Includes some temporary gross debugging stuff.
* Made debugging less gross by giving operators and channels a reference back to their owner.
* Fix status port address in OPL chips. Reduce ADPCM volume to match previous implementation.
* Fix Y8950 ADPCM start. Return masked status properly.
* Initial cut at OPLL mapping.
* Add YM2413 support based on ymfm; renamed vrc7snd to ds1001; added YM2423 amd YMF281 variants as well. Instrument data is now loaded via external ROMs. Added 'depress' envelope support to the core engine. Fixed a number of issues in the ymopll_engine. Documented hard-coded values. Moved register clear into register-specific reset.
* Add missing identifier.
* Y8950 is OPL not OPL2.
* Some documentation cleanup. Consistency fixes in the register classes.
* Consolidate large comments. Add support for delayed modulators for OPL. Broke out 2-op and 4-op cases to help simplify logic. Fixed overflow handling in fp encoding.
* Fix silly bug.
* Changed operator assignment mechanism to be more readable. Added prepare method to be called at the start of sound update. Added ALL_CHANNELS constant to register files. Updated all consumers to call prepare and use constants where applicable.
* Move YMF262 and YMF278B to use new FM engine for OPL3/4. Fix several issues in OPL3 logic, which now seems to work ok.
* Minor fixes. More documentation.
* Fix MSVC build.
* Add caching of data to prepare methods to improve performance. Moved non-register decoding logic out of the .h file and into .cpp file. Move phase_step calculation into register class.
* More notes. Removed keycode from cache. Split 2/4-operator outputs into separate functions. Changed OPN/OPL to use templates for variants. Added channel/operator_offset helpers.
* Fairly substantial overhaul of register interface. Register interface is now stateless and contains family-specific state. Channel and operator accessors are prefixed by ch_/op_ now and require an offset to the specific channel or operator. Moved LFO/noise generation into register class, along with keyon logging.
* Add noise back to OPL/OPLL
* Added early-out for low envelope. Moved waveform logic out into family-specific code. General clean up of ordering. Reduced family base class to minimal needed.
* More aggressively track active channels to help performance.
* Use only summing outputs for consideration of active channels. Centralize the logic of determined 4-op vs 2-op.
* More conservative channel deactivation.
* Add helper to compute the sample rate and use it in all implementations. Remove unneeded chnum/opnum members.
* Fix error in YM2612 that caused crashes.
* Switching parameters and locals to 32-bit values gives a noticeable performance boost. Checkpoint 1.
* More moving to 32-bit values. Checkpoint 2.
* Last of the 32-bit promotions.
* Ensure SSG inverted flag is only tested on systems with SSG support in the innermost loops.
* Make most constants 32-bit as well. Expose some constants via the engine class.
* Expand waveforms ahead of time. Optimize the attenuation lookup a bit.
* If volume is low, don't erase output, just leave it alone. Fixes missing sound in raimais.
* Replace a couple of magic numbers with constants.
* Normalization of FM engine usage across consumers.
* Removed explicit external prepare() call; this logic is now automatically done after writes and periodically. Changed OPL/OPLL to use native formats for block/fnum. Fixed waveform generation. Fixed PM and AM depth on OPL/OPLL.
* Cache multiple value. Clean up output handling a bit.
* Move multiple caching ahead of phase step caching.
* Fully split OPLL from OPL. Remove many hacks now that OPLL registers can have state. Created shared helpers between OPL/OPLL. Removed more aggressive channel disables since it was not rhythm friendly and didn't really buy much.
* Remove old comment
* Remove bad write in OPL mode case. Fixes fsoccer intro. Only call set_reset_status() once per mode call.
* Remove FM output boost in YM2608/2610. Not sure why I did that. Better matches previous volume now.
* Make AM/PM logging less confusing.
* Let's actually set DYNAMIC_OPS properly, eh?
* Improved logging.
* Comment cleanups. Add constant for dynamic phase. Pre-shift sustain level. Srcclean.
* Fix memory regions on YM2608 games.
* Clean up ymadpcm to line up with recent ymfm changes.
* y8950: Reshuffle read/write handlers. Rename them to less confusing names.
* ym2413: Reshuffle read/write handlers. Rename them to less confusing names.
* ym3526/ym3812: Reshuffle read/write handlers. Rename them to less confusing names.
* ymf262: Match read/write details to datasheet and previous tests.
* Use a constexpr function instead of macro for packing operator numbers. Pre-compute OPM LFO waveforms.
* Generate OPL4 engine to support the proper clock divider and new flags. Update YMF278B to use FM timers and status rather than replicating the logic.
* Fix 4-operator enable on new OPL4 instance.
* Fix FM downsampling and adjust balance in YM278B.
What's missing:
- parameters (like the disk name when it exists)
- possibly a cleanup of ram_open and friends (but not sure of the appropriate direction in which to go)
New BSD-licensed implementation of Yamaha OPN and OPM FM audio chips, along with new device drivers for YM2203, YM2608, YM2610, YM2610B, YM2612, YM3438, and YM2151 based upon these.
New working machines

New working clones
------------------
QuizKid Racer (MM5799 version) [hap, Sean Riddle]
If you want to build 64-bit and 32-bit in the same tree without them
stomping on each other, use SEPARATE_BIN=1 (you already need to do this
for TOOLS=1 anyway).
* Separated Acorn IOC and MEMC into devices.
* Emulated 8051-based serial keyboard.
* acorn_machine/memc.cpp: Ensure only one logical page is mapped to a single physical page.
* Fixed RISC OS POST IOC register test.
* aa310.cpp: Added debug code to display RISC OS POST failures.
-machine/archimedes_keyb.cpp: Dumped Acorn Archimedes keyboard microcontroller. [Phil Pemberton]
- sa1110: Added rudimentary support for the ICP and DMA blocks. [Ryan Holtz]
- sa1111: Various changes. [Ryan Holtz]
* Hooked up I2S audio DMA support.
* Hooked up IRQ support.
* Hooked up basic GPIO support.
- uda1344: Added initial pass at audio support, based on DMADAC. [Ryan Holtz]
- sed1356: Added support for BitBLT solid-fill command. [Ryan Holtz]
- jornada: Added more keys, touch pen support, and fixed EEPROM access. [Ryan Holtz]
- render.h: Split out layout class declarations into rendlay.h, with some adjustments for the resulting incomplete types (std::reference_wrapper unfortunately does not allow these by C++17 rules)
- rendlay.h: Move old header contents to layout/generic.h
- vecstream.h: Revert changes made in aa29519528. The std::string_view conversion has been made a non-member function (util::buf_to_string_view) and moved to coretmpl.h.
- strformat.h: Remove the using declaration importing util::string_format into the global namespace. It has been moved to emucore.h and a few tool sources; other references have been qualified.
- osdcore.h: Split out file, directory and path classes and methods to a new header (osdfile.h), Doxygenizing the documentation comments.
- Disaggregate many #includes that were including other standard or custom headers. emu.h now includes basically the same things that it did, but other headers have been streamlined; for instance, emucore.h no longer stealth-includes osdcore.h several ways.
Added methods for enabling and disabling breakpoints and watchpoints,
and made debugger views update when breakpoints/watchpoints are
manipulated from Lua. Made breakpoints and watchpoints objects rather
than tables. (It’s not possible to enable/disable a breakpoint or
watchpoint from the object itself, you have to go through its owners'
debug interface.)
Exposed more device_t members for dealing with child/sibling tags and
devices. Also provided a way to get regions/shares/banks from a device
using relative tags rather than going through the memory manager with
absolute tags.
-netlist: Give devices the C++17 namespace treatment.
-Tidied up compiler warning options for 3rdparty.
-emu/render.cpp: Exposed a few information view item properties.
I've guessed whether break or [[fallthrough]] is appropriate. In cases
where it looked particularly suspicious, I added a FIXME comment. All
of these changes should be reviewed by someone familiar with the code.
- Implemented memory mapper for CP/M.
- Serial printer port.
- External RAM is now scrambled.
- SuperCart bankswitching board implemented for Aquaricart.
- Cartridge images of size 4K, 8K, 16K now supported, was previously 16K only.
* Implement TT5665 emulation
Similar as OKIM6295, but with Support more ROM capacity and phrase spaces, 2 sound outputs
used in bowltry, igs_m036 (for some hardwares with TT5665, ex: cjddzsp)
bowltry.cpp: Fix game name (BOWLING TRY! in both poster and PCB)
* bowltry.cpp: Typo
* Fix endline
* tt5665.cpp: Reduce unnecessary argument
This fixes the "typing on all keyboards at once" issue. You can now
enable and disable keyboard/keypad inputs per device in the Keyboard
Mode menu. Default is to enable the first device with keyboard inputs,
and all device with keypad inputs but no keyboard inputs. The settings
are saved in the CFG file for the machine.
Typing in natural keyboard mode only ever types on one keyboard at a
time, but now you can control which keyboard it types on, as it will be
the first enabled keyboard.
You can easily try this out with something like:
mame64d zorba -rs232 terminal cpm
-ui/inputmap.cpp: Show device descriptions as well as tag paths.
-mac128.cpp: Fixed mouse axis wrap compensation, cleaned up mouse code,
eliminated static variables for mouse input state.
You could see the issue with wrap detection easily enough just by
running mac128k/mac512k/macplus and tapping the arrow keys to move the
mouse one pixel at a time. As you moved past the point where the axis
count wrapped, it would move one pixel in the opposite direction.
There were two function static variables related to mouse input state,
probably still lurking from when the code was initially made to use a
driver state class. This obviously messes with save states and prevents
multiple instances.
- bus/a2bus/mouse.cpp: Fixed mouse axis wrap compensation.
This device had the same bug with wrap compensation as mac128k.cpp.

vsmile_cart: V.Smile Tanz Mit Center (Germany), V.Smile Défi Gym (France), Gimnasio Interactivo V.Smile (Spain)
-vsmile: Added support for the Jammin' Gym Class dance mat. [bmx, Ryan Holtz]
* Split hc55516 core into separate cores/subclasses for hc55516 and hc55532 (new 'digital' implementation based on decap/die tracing) as well as mc3417 and mc3418 (old existing 'analog' implementation left alone) and hooked the hc55516 and mc3417 implementations to the appropriate hardware drivers. This should vastly improve CVSD sound quality in drivers that use the hc55516. [Lord Nightmare, Sean Riddle]
* Made Exidy's mouse trap use a timer to clock the mc3417 and update the state readable by the z80 rather than relying on the mc3417 to accept a clock parameter and update the z80 state via a callback. The timer implementation ensures proper synchronization and prevents missed clock transitions from the z80 side causing noise in the CVSD audio. [Lord Nightmare]
* Added a biquad-based 2nd order filter emulation for an audio stream (to go along with flt_rc 1st order filter emulation) and hooked it to Exidy's mouse trap (mc3417) and williams drivers (hc55516) following the original schematics. For hc55516 this is necessary as the original chip produces a very pronounced audible 16khz 'carrier' in its output audio even on the real chip, and these filters suppress this. This also happens to a lesser extent with the 8khz quieting waveform noise on both mc3417 and hc55516. [Lord Nightmare]
* Made Williams System 11 and s11_bg relative sound mixing more accurate to the original audio flow on the PCB itself. [Lord Nightmare]
* Switched Williams Joust 2 to use the s11_bg common sound device rather than its own implementation. [Lord Nightmare]
* fmtowns: add a SCSI card slot for the original models
- Add a slot device for the Model 1/2 dedicated SCSI slot
- Add a device for the FMT-121 SCSI Card
- Modify the I/O maps and machine configurations so the slot and the
integrated controller don't overlap
Moved MS DIB parser out of ICO file reader and made it available for
artwork and layout images.
Added more efficient I/O and better error checking for JPEG file loading
(MAME will no longer exit immediately on a bad JPEG file).
Made caller responsible for opening files for loading images, to avoid
decompressing images used in ZIP/7z artwork multiple times.
Added support for JPEG and Windows DIB to picture_image_device.
Added support for SVG image files in external artwork.
Added support for using I/O port value for animation state and masking
animation state values.
Made bounds elements more flexible in layouts.
Reworked headers to reduce dependencies.
Updated layout file format documentation.

TV MegaMax active power game system 30-in-1 (MegaMax GPD001SDG) [David Haywood]
* added files for the VT APU type, currently no extra functionality, but will be built upon
* psixptty: Fix for FreeBSD
We need to check for __FreeBSD__ not __FreeBSD_kernel__
* FreeBSD: Use gl includes from pkg-config
FreeBSD doesn't install the includes from 3rdparty software in a default
location so use pkg-config to get the correct path.
* FreeBSD: genieos is named simple bsd
* Most OpenGL link issues fixed. Two remain from drawogl.cpp.
This isn't working anyhow.
* "-video accel" now uses WebGL. This allows GL based scaling and
provides a performance improvement.
* Fixed pong and other games by adding another function to the
exception whitelist
* Target now is mame.html. This allows emrun to be used for testing.
mame.js is created as well and thus the current behaviour
unchanged.
This adds support for the mini digital cassette recorder that can be
found inside a P2000t. This implementation is based on documentation
that can be found in https://github.com/p2000t/documentation.
In memory of NPM Jansen, who taught me all the magic of bits and bytes.
* animalc: Pile kludge upon kludge for poorly understood video timing register
* gocowboy, itazuram: Increase frequency of one timer interrupt (and hopper timing in gocowboy)
* kc82, kp69: Modernize state_add syntax
* Removed device and macro header files.
* All of those can be generated automatically so going forward there is
no need for these any longer.
* Introduced the modules concept. Modules are netlists for which
automatic lib entries are generated.
* Going forward you just store them in macro/modules and they will be
automatically registered as device elements.
* You need to do a "make generated" is src/lib/netlist/build
* Some_device.cpp still needs to be added to netlist.lua
* Added documentation on how to add devices to netlist.
* Please refer to adding_devices.md for more information.
* Ported Cirrus Logic CS8900A Crystal LAN MAC emulation from VICE and hooked it up to Apple II card device.
* Adds Ethernet networking support for Apple IIgs.
* removed include directory src/lib/netlist from various genie files to
avoid potential issues.
* Code using netlist should use #include "netlist/*".
* Updated includes.
* Fixed standalone makefile depend target to properly deal with relative
paths.
IMGUI_DISABLE_OBSOLETE_FUNCTIONS was defined in osd/modules.lua but not
in 3rdparty.lua. As a result, two different variants of struct ImGuiIO
were being defined, causing a C++ One Definition Rule violation
