- Hooked up PIC and connected keyboard and vblank interrupts
- Implemented HLE keyboard (all keys mapped, using the translation ROM for keycodes)
- Increased shared memory to 40k
- Fixed interrupt flags register
- Implemented cursor and roll offset
* 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.
* Moved sprite handling to a device.
* Adjusted audio balance on mechatt (channel 0 was overpowering everything).
* Adjusted priority handing on mechatt (planes now correctly rise from underground hanger on stage 3, train carts in later level).
* Split driver in two, general refactoring etc.
* Removed player 2 inputs from mechattu1 - it doesn't respond to them at all.

Fedora Linux.
* Explicitly mentioned that Ubuntu modifies GCC to enable "fortify
source" by default in the relevant section.

* Added compile-time option to disable recompiler W^X mode.
* NuBus image device current directory doesn't need to be pinned.
- 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.
* shuffle a few things around re: the BBL ST2302U based handhelds, give bbl338 its own map due to internal ROM etc.
* fake some interrupts on bbl338
* better document test draw command, so that we can verify we're in test mode

-st62xx: Various changes. [Ryan Holtz]
* Fixed RETI and LD rr,A opcodes.
* Optimized internal register handling.
* Converted to use logmacro.
* Added initial timer support.
* Started moving Lua class reference to docs. Expecting people to find
the class reference material in the source isn’t going to help make it
approachable. The docs allow longer explanations, better formatting,
and cross reference links.
* Added another layout scripting example to the docs.
-goldnpkr.cpp: Minor clean-up.
* Improved the short names for Witch Card and Witch Game clone sets.
* Made Witch Up & Down artwork clickable.
* Added working Video Klein sets where the parent is a working Video
Klein set to the tiny subtarget.

a readon.
* set additions, see main decription
* not working additions, see main description
* more not working bits, see main description
* more not working additions, see main description
* consistency fix
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.

* Translate clamp_to_12bits_neg to a constexpr method
* Fix crashing in main ms32 driver, except it now has very broken priority for seemingly no reason
* Fix nasty spriteram buffer RAM allocation bug
* Make objectram_size to be calculated at init time
* First (naive) pass in moving common interface to a ms32_base_state
Move m_irqreg save state from video_start to machine_start fn;

Add bitswap for bnstars1 mahjong panel;
.bytes() -> .length() for objectram_size;
* bnstars: template video handlers
* bnstars: fix config, split sprite chips/gfxdecode/palette into two, fix palette ranges
* ms32.cpp: implement proper irq acknowledge lines
* Add config setter in sysctrl for inverted vblank/field lines, make tp2ms32 and wpksocv2 happy
* Move f1superb to own state
* MS32 merge sound maps
* Remove TIMER_DEVICE_CALLBACK_MEMBER in favour of emu_timer
The things that were previously called device iterators are not
iterators in the C++ sense of the word. This is confusing for
newcomers. These have been renamed to be device enumerators.
Several Lua methods and properties that previously returned tables now
return lightweight wrappers for the underlying objects. This means
creating them is a lot faster, but you can't modify them, and the
performance characteristics of different operations varies.
The render manager's target list uses 1-based indexing to be more like
idiomatic Lua.
It's now possible to create a device enumerator on any device, and then
get subdevices (or sibling devices) using a relative tag.
Much more render/layout functionality has been exposed to Lua. Layout
scripts now have access to the layout file and can directly set the
state of an item with no bindings, or register callbacks to obtain
state. Some things that were previously methods are now read-only
properties.
Layout files are no longer required to supply a "name". This was
problematic because the same layout file could be loaded for multiple
instances of the same device, and each instance of the layout file
should use the correct inputs (and in the future outputs) for the device
instance it's associated with.
This should also fix video output with MSVC builds by avoiding delegates
that return things that don't fit in a register.
