- CPU
  . DEC T11: More accurate emulation of interrupt acknowledgment. Added PF and HLT interrupts. This is accurate behavior for the T11, but it makes some of the driver changes a bit more awkward than they probably should be, given that one device is standing in for every CPU vaguely related to the PDP-11 family. Galaxy Game obviously wasn't written for a T11, and the BK-0010's K1801VM1 doesn't look like a lot like the T11 either.
  . Hitachi HD6309: Removed 0x20 opcode (m6809\hd6309.ops). Note $1020 is an illegal opcode on the 6309. On the 6809 it is a rarely used form of LBRA. I tested on a real 6309 and $1020 vectors to Illegal.
  . Intel 8085A
    . Stop in debugger after an interrupt is taken, not immediately before.
    . Interrupt updates: Eliminated special-casing and three-in-one loading of CALL (and JMP) vectors in favor of fetching each byte in succession like a normal instruction. Added INTA callback, called only when INTR (and not any other interrupt) is acknowledged. Enforce that TRAP (NMI) must be held at a high level until acknowledgment.
  . Intel 8086: Correct a fortuitously harmless typo in state registration (i86\i86.cpp). Updated m_prev_ip (and therefore CURPC) after taking interrupt. Added exception hook for debugger gex command.
  . Intel 8086/80186/80286: Don't automatically clear IRQ state upon acknowledgment (i86\i86.cpp). Added byte registers to debugger state and improved tracking of previous PC for debugger. Added exception hook for debugger gex command.
  . Intel 80186: Initialized variable as needed to avoid timing regression in some leland.cpp games in debug devnoclear builds (i86\i186.cpp)
  . Intel 80286: Don't clear INT state upon acknowledgment and added exception hook for debugger (i86\i286.cpp). Updated m_prev_ip (and therefore CURPC) after taking interrupt.
  . Intel i960KB: Added missing opcodes. Rewrote disassembler (i960\i960dis.cpp). Added partial support for all IAC messages (i960\i960.cpp).
  . Mitsubishi M37710S4: Rename some registers to agree with Mitsubishi documentation
  . Motorola MC6801
    . Clear OCF when output compare register is rewritten, not read from. Fixed #define TOH.
    . Removed hack, the real cause of (MESS) Coleco Adam locking up at boot was fixed recently with TCSR_OCF clear. TCSR upper 3 bits are read-only.
  . Motorola MC68000: Added exception hook for debugger gex command (m68000\m68kcpu.cpp). Added fmod instruction (m68000\m68kfpu.hxx).
  . NEC Vxx: Added exception hook for debugger gex command. Added byte registers to debugger state. Improved tracking of previous PC for debugger. Use more NEC register names.
- SOUND
  . K053260 KDSC: Fixed panning, interrupts and general volume for The Simpsons.
  . Namco C352: Allow byte accessing. Modernized save states. Added notes. Use shorter/correct type/argument values.
- DEVICE
  . 6522 VIA: Correct vocabulary, raise cb2 on shift in to make open-collector work correctly. Don't lose sync on edge count when the serial clock is external.
  . Discrete Netlist
    . Fixed Clang-tidy warnings. Fixed some windows build issues in build\makefile. Improved const-awareness and tidy changes. Identified a number of code locations which could accept const arguments.
    . Added 74163 4-bit counter, 74393 device and unit test.
    . More code maintenance. Make some calls private which were public before. Eliminated functions which would be executed only once. Make terminal reference functions in twoterm.h return const. Clearly identify the use cases which need a non-const ref to terminals.
    . Fixed "--cmd=listdevices". Broken for quite a while this is now working again (prg\nltool.cpp). Fixed documentation build on windows in makefile. Documentation should be created on Windows using make mingw PARAMS=doc. Admittedly this is ugly and the makefile needs to be changed to use something like "make HOSTOS=windows doc".
    . Fixed some edge cases in static compile. Comes with a new version of static_solvers.cpp.
    . Stub implementation of 566 VCO. Added NE566 to netlist.lua. Fixed output stage on NE566
    . Added the NE566 as a macro device. The device can be found in nlm_other.cpp. Removed nld_ne566.*. Added SYS_SW, SYS_SW2 and SYS_COMP. These are single switch, alternating switch and a analog comparator with digital outputs. Renamed RES_SWITCH to SYS_SW. Added example ne566.cpp in netlist/examples.
    . nld_log now writes out last value at end of run
    . Fixed polarity issue in CCCS device. Note: This affects all use cases of CCCS.
    . Faster LM3900 model (macro\nlm_opamp.cpp)
    . Unknown parameters really should be fatal. Unknown parameters like Solver.ABCD now will cause a fatal error to be generated. Fixed unknown parameter on ne566 and VS 2019 build.
    . Fixed a long standing bug in proxy/family code. This never materialized because proxies were always connected to GND in existing netlists (netlist\nl_base.h).
    . Added simple ZDIODE model. The model is driven by three additional model parameters: NBV, IBV, BV. Example code how to define a typical 7.5V Zener diode: ZDIODE(ZD, "D(BV=7.5 IBV=0.01 NBV=3)") or NET_MODEL("A1234 D(BV=7.5 IBV=0.01 NBV=3)") ZDIODE(ZD, "A1234")
    . Changed license for netlists in examples to CC0 (public domain). Moving over to Clang-tidy-11 and enabling more warnings.
    . Adding prandom.h (PseudoRandom Number Generator (Mersenne Twister))
    . Added two noise sources. The two sources act as voltage sources, though noise may also be injected as conductivy or current noise. SYS_NOISE_MT_U: Mersenne Twister uniform noise and SYS_NOISE_MT_N: Mersenne Twister normal noise. nld_sys_noise is templated: Using NETLIB_NAME(sys_noise_mt_u) = NETLIB_NAME(sys_noise);. Thus the approach is scalable. The implementation is state save aware, and thus reproducible results are guaranteed. An example use case is provided as well, see examples/noise.cpp.
    . Restructered the save state system. This change makes state saving contract based. Objects which need to save state need to have the following template member: template  void save_state(ST &st) { /* Example */ st.save_item(m_p, "m_p"); st.save_item(m_buf, "m_buf"); }. This member function is called when the object is passed to the state manager save function.
    . Fixed two nlwav bugs. First one corrupted wav files produced on windows. The second one produced wrong sample integration results.
    . New nlwav functionality: nlwav now supports 16 and 32 bit integer format (wav16s, wav32s) as well as 32 bit float format (wav32f). The "wav" format is no longer supported. Added support for high and low pass filtering the wav output. Dynamic volume adjustment (use "-a 0") --hpboost can suppress spikes at the beginning of the file (<10ms). The addition of the float format simplifies debugging significantly since it covers the whole dynamic format. Added nlwav to the local VS 2019 build.
    . Added elif processing to preprocessor (plib\ppreprocessor.cpp)
    . Moved nld_power_pins to nl_base.h. This removes a large number of dependencies on nlid_system.h.
    . Reduced the usage of NETLIB_CONSTRUCTOR_DERIVED to implement dip package objects. This aligns the programmatic approach with the approach used in the macro folder, i.e. using netlists. Untangle model definition and interpretation as well. This changes are a first step in aligning models and families and thus simplify the source further.
    . Fixed VCCS definition (netlist\analog\nld_fourterm.h)
    . Removed family_setter. Naming alignment and family becomes model. Architecture cleanups. Reviewed reset logic. Pass truthtable family as string to factory. This is another set of changes on the path to align logic families and models. As a side effect, the object model now makes a clear distinction between analog models and logic models. The number of macros in nl_base.h has decreased significantly due to these changes.
    . Provided more information for warning on connecting two terminals already on the same net
    . Logic devices now support model parameter. This a big forward to allow reuse of code. Still a longer way to go but the foundation there. Also brings quite a number of simplifications and dead code removal.
    . Added undef support to the preprocessor. Added support for empty #defines to preprocessor. Added detection and reporting of re-definitions (netlist\plib\ppreprocessor.cpp)
    . Extended functionality and code cleanup: Working macro level parameters. Simplified code significantly. Fixed a number of hidden issue. Dead code removal. It is now possible to define netlist level parameters (see example). The code also has been prepared to allow something along the lines of LIBENTRY_MODEL(DM74LS00_DIP, DM7400_DIP, "LS74XX") to define a LS version on top of an DM7400_DIP bare TTL implementation. This however will need more efforts to existing devices to honour some timing adjustment in the model definition. It will already honour different output specifications between LS series and bare TTL if connected to analog components.
    . Code cleanup to better separate the following stages: Parsing, setup and run. In addition preliminary native tristate support was added. Not yet production ready, please don't use it.
    . Added 74377/74378/74379 devices to netlist. Re-do the 74377/8/9 as macros. Added devices CD4013, CD4069 and CD4070.
    . Fixed Breakout SLOW_BUT_ACCURATE
    . Rewrote rom devices from scratch. This is a rewrite from scratch for rom devices. It uses a generic template to implement rom devices which is used together with a description struct to define a rom device. This leads to highly efficient code since all information is available at compile time. This is also a step forward to support tristate outputs. All rom devices covered by this approach have tristate or open collector outputs and thus all code changes to support tristate outputs can now be made consistently in one file.
  . GP9001 VDP: Fixed GP9001 sprite drawing, fixes Truxton II sprites flicker or disappear during certain parts of the game (ID 07642).
  . Hitachi HD44780 A00 LCD Controller: Allow function set register to be updated again right after changing the data length. Allow function set register to be updated again right after changing the data length.
  . Keyboard
    . Fixed typos in PORT_CHAR definitions (machine\keyboard.cpp)
    . Fixed for UI Paste with the Default Serial Terminal (emu\natkeyboard.cpp). This fixes the ability for one to use UI Paste with the Default Serial Terminal. Without this fix, 8 characters @^&()\:" cannot be pasted from the UI.
  . I2C Memory: Created i2cmem sub classes for all used device types, fixed the buffer sizes that were wrong, removed the methods for modifying the data & buffer sizes and changed the drivers to use the correct types.
  . Intel 8156 RAM, I/O & Timer: Allow writes to port registers to alter latches whether or not output mode is configured. Turn logging back off.
  . Intel 8259 PIC
    . Z80/8085 slave PICs need 32 bit vectors. Emulated three-cycle acknowledge for non-8086 mode (machine\pic8259.h).
    . Moved recently-introduced inta_call hack down into the only Z80-based driver that still needs it. The hardware-accurate way of synthesizing multiple INTA pulses in a Z80 system (which involves rerouting what would otherwise be normal memory reads) is not so simple and deservedly rare.
  . K052109 Tilemap Generator: Correct video clocks (drivers\simpsons.cpp and video\k052109.cpp)
  . K056230 LANC: Misc demacroization. Documentation updates.
  . Motorola MC6845 CRTC: Max visible lines might not be what really is displayed, see 8088mph (ibm5150.xml Software list).
  . Namco C140
    . Updated data bus behavior and support 12 bit PCM. Verified from Assault (namcos2.c) schematics. Added/Updated notes. Use shorter/correct type values. Fixed address/data bus bits and modernized save states. Fixed spacing. Reduced unnecessary lines and duplicates. Moved little endian interface in c140.h. Moved bankswitch behaviors in each drivers. Reduced noisy sound regression in previous commit remain in vgmplay for compatiblity. Implemented some features from QuattroPlay by superctr. Splitted sound stream update and host interface.
    . Fixed C140 input clock source according to crystal for gal3.cpp and namcos21*.cpp. Added notes.
  . Signetics SCN2674 AVDC: Delayed commands use display pointer address, not screen 2 address.
  . Z80 SCC Channel: Don't invent data (m_rx_fifo_rp_step). Clear IUS not IP.
- atarisy1.cpp: Some of the BIOS roms were wrong (136032.105.l13, 136032.115.j10 and 136032.107.b2) (ID 07656). Clone Road Blasters (cockpit, rev 1) also expects LSI BIOS.
- chihiro.cpp: More precise implementation of rcc and rcp vertex shader instructions (video\xbox_nv2a.cpp)
- chihiro.cpp, naomi.cpp and triforce.cpp: Eliminated get_read_ptr (machine\naomigd.cpp)
- cischeat.cpp
  . Added OKI mirrors to Arm Champs II, fixing missing/erratic sounds.
  . Fixed Scud Hammer/Arm Champs II irq and refresh rate to be measured 59.17 Hz instead of 30. Moved armchmp2 specific I/Os into own state machine, and demoted it to MNW because the arm input not exactly understood and not supposed to require user input at POST anyway.
- dec8.cpp
  . Restoring coin-up sound
  . Identified 3 bad bits in Captain Silver MCU dump, hooked up MCU.
- ertictac.cpp (Archimedes): Switched Erotictac driver and (MESS) Archimedes 310 over to use machine\pcf8583.cpp, which is not currently based on i2cmem.cpp but might be worth merging in the future.

  . Moved delayed sprite drawing function into screen_vblank
  . Use generic gfx layout in suprnova.cpp. Fixed CPU clock related to XTAL. Use device for screen.
- jaguar.cpp: Moved I/O handlers to specific maps, untangle register array usage, to be completed. Nuke duplicate I/O accesses, rename to iobus_r/w, make go_w to be an actual line. Fixed addqmod & subqmod modulo mask for DSP. Refactor TOM to host CPU function, and fix GPU irq lv 3 when a GPU object is encountered. Fixes mutntpng and atarikrt booting. Fixed Jaguar irq line to 2, trusted. Start reworking the blitter. Relicensed to BSD.
- kikikai.cpp: Hooked up Kick and Run MCU. Split up kikikai class.
- leland.cpp: Initialized variable as needed to avoid timing regression in some Leland games in debug devnoclear builds (i86\i186.cpp)
- model3.cpp: Added screen raw parameters
- namconb1.cpp: Reduced duplicates. Moved virtuals under protected. Use shorter/correct type values and fixed spacing. Converted sprite bank delaying behavior into unique_ptr. Removed unnecessary device.
- naomi.cpp: NAOMI2 USA BIOS Rev.C and Korea BIOS Rev.B dumped
- peplus.cpp: Fixed regression in peps0615 introduced in MAME 0.220, the game writes to the page buffer then sends a spurious start condition before the stop condition that writes the buffer.
- peyper.cpp: Simplified handler signatures and mask SL for reads
- redalert.cpp
  . Audio updates (audio\redalert.cpp): More accurate emulation of 555-based IRQ timing. Use 6821 PIA device to generate sound IRQ in Demoneye-X. Simplify handler signatures.
  . Various fixes
  . Fixed Panther input labels, marked maincpu ROMs as bad and volum (sic) lever is vertical not horizontal. Reduced input defs. Added communication hand-shake and fixed audio mapping, emits a few sounds.

- Renamed (magibomb) to (magibomba)
- MAME
  . DEVICE
    . Removed colon as a patch seperator (emu\diimage.cpp)
    . Initialized a couple of variables, fixes numerous bugs in devnoclear debug build with BIOS roms in devices (emu\device.cpp).
  . Timer system
    . Added to_string() to get a human-readable version of the time (emu\attotime.cpp)
    . Periodic timers are not adjustable, be a little more affirmative about it (machine\timer.h).
  . LUA engine: Consolidated code for pasing enum strings
  . Programmable Logic Device (PLD): Added GAL20V8 support to the jedutil tool
  . Misc demacroization (machine\k056230.cpp, drivers\model2.cpp, stv.cpp, machine\315-5838_317-0229_comp.cpp and pgmprot_orlegend.cpp)
  . Moved some RC timing macros out of the core (machine\rescap.h; drivers\bfm_sc1.cpp, bfm_sc2.cpp, capbowl.cpp, gottlieb.cpp, lockon.cpp, mpu3.cpp and mpu4.cpp)
  . Simplified many handlers and READ/WRITE macros removal 
- VGM player: Implemented some features from QuattroPlay by superctr
- Compiling
  . Fixed GCC 10 uninitialized (modules\vzdos.cpp) struct warning and GCC 10 fix for sqlite3 (scripts\genie.lua)
  . Get rid of missing end-group warning for MinGW (scripts\genie.lua)
- Debugger
  . Refocus debugger on CPU when one of its watchpoints is hit (debug\debugcpu.cpp). This solution may be less than ideal for some multiprocessing environments where CPUs share spaces, but it prevents the focus from shifting unpredictably to whichever CPU happens to be next in line to execute (e.g. when synchronization for a soundlatch write aborts the original CPU's timeslice).
  . Added PC to debugger exception hit message (debug\debugcpu.cpp)
  . Added optional condition parameter to debugger gex command
  . Fixed focus command (debug\debugcpu.cpp)
  . Fixed debugger regression with systems such as fi6845/fi8275 where a DMAC or other non-focusable executing device is scheduled first of all (debug\debugcpu.cpp)

- CPU
  . ADChips SE3208: Use callbacks for interrupt acknowledgment
  . AM9517A: Assert EOP during rather than after final DMA transfer. uPD765 may not care much about the timing of this signal, but other devices (notably NCR5380) expect it to occur simultaneously with the read/write strobe. This *might* break drivers/devices that expect EOP to be continuously active as it was previously emulated, rather than pulsed. Those likely need to latch the edge of EOP or one of the ACK signals.
  . Intel I386: Added alias for fstp st(i) (cpu\i386\x87ops.hxx)
  . Intel P8x9x: Added more device types, some with 16-bit buses. Implemented quasi-bidirectional port structure (cpu\mcs96\i8x9x.cpp). Location 0 is just 0 (mcs96\mcs96d.cpp). Fixed EXTINT and added some very preliminary HSI stuff. Implemented HSO CAM status flags in IOS0 (cpu\mcs96\i8x9x.cpp).
  . Motorola MC6800: Removed unneeded 6800ops workaround
  . Motorola MC68000
    . Don't iterate to save arrays. Eliminated legacy prepost registration (m68000\m68000.h).
    . Pload does an explicit table walk (m68000\m68kmmu.h)
  . Motorola MC68010: Correct DBcc timings. This fix prevents certain Marble Madness clones (e.g. marble2) from watchdog resetting while cheksumming the ROM (m68000\m68k_in.lst and m68kops.cpp).
  . Motorola MC68705: Added more documentation of mask ROM versions. Added HD6805S1 device for future use.
  . Motorola MC68HC05: Support M68HC705C8A internal banked RAM (cpu\m6805\m68hc05.cpp). Only reset due to NCOP when it's enabled.
  . NEC uPD7810/11: Nominally distinguish NMOS and CMOS device types
  . NEC Vxx: Added 8080 mode (nec\nec80inst.hxx)
  . Signetics 2650: Get the vector from the IRQ ack request, removed use of set_input_line_and_vector and HOLD_MODE. Fixed interrupt-related regressions in 2650-based games.
  . Zilog Z8000/Z8002
    . Clean up reset sequence (don't read program space at device_reset time). Use callbacks to vector all external interrupts; correct data pushed during acknowledgment. For NMI and NVI, a vector is read from the bus but merely stored on the stack (most Z8000 systems seem to just leave the bus open here). For VI, the vector offset calculation has been changed for the Z8001: the low byte is multiplied by 2, not 4, so AD0 generally must be driven low.
    . Fixed unreliable order of operations in operand calculation for certain instruction modes (z8000\z8000cpu.h)
    . Memory access refinements. Implemented byte smearing for memory and I/O writes. More accurately handle unaligned word I/O without breaking PCOS-M24.
    . Z8001: Expanded address space to 23 bits
    . Z8002: Correct width of I/O space (16-bit, not 8-bit). Documented pinout.
  . Zilog Z80180: Internalized certain registers and make clock divider software-selectable
- SOUND
  . Atari C012294 POKEY and Yamaha YM2414 OPZ: Modernized struct saving
  . Discrete Sound: Documented DISCRETE_FILTER1 and DISCRETE_FILTER2 better (sound\disc_flt.hxx)
- DEVICE
  . 7474 TTL: Changed output to deliver either 0 or 1, not -1.
  . 74161 TTL: Fixed state machine and made TC signal asynchronous
  . 74543 TTL: Added octal registered transceiver
  . Atarigen and Atariscom (General functions for Atari games)
    . Separated various drivers from atarigen_state (machine\atarigen.cpp; drivers\arcadecl.cpp, eprom.cpp, klax.cpp, shuuz.cpp, toobin.cpp and vindictr.cpp)
    . Moved interrupt handling down into drivers (machine\atarigen.cpp; atarig1.cpp, atarig42.cpp, atarigt.cpp, atarigx2.cpp, atarisy1.cpp, atarisy2.cpp, blstroid.cpp, cyberbal.cpp, gauntlet.cpp, rampart.cpp, skullxbo.cpp and xybots.cpp)
    . Eliminated ATARI_CLOCK_xxxMHz macros in favor of standard XTAL constants (machine\atarigen.cpp)
    . Separated 'Atari Sound Communications' from machine\atarigen.cpp. Moved IRQ handling to audio\atarijsa.cpp (not a property of the actual device)
  . DECO 55 / 56 / 74 / 141 Tilemap Generator: Added notes of Locked 'n Loaded PCBs. Fixed transparency/transmask handling in custom draw case.
  . DECO BAC06 Tilemap
    . Fixed flagsmap handling. Reduced unnecessary values.
    . Updated drawing behavior. Use tile callback. Converted pen masking into set_transmask behavior. Added notes. Reduced duplicates and unneeded values.
  . DCS Audio: Removed some dummy_space() calls. Fixed reset control. Changed DCS reset control to active low in Midway drivers (atlantis.cpp, kinst.cpp, midvunit.cpp, seattle.cpp, vegas.cpp, midtunit.cpp, midwunit.cpp and midxunit.cpp).
  . Discrete Netlist
    . Fixed parsing of netlists by nltool. Reduced memory allocation calls in non-core code. Performance improvement.
    . Fixed netlist syntax errors (machine\nl_dpatrol.cpp). Fixed standalone build and doxygen mainpage (netlist\build\makefile and netlist\documentation\mainpage.dox.h).
    . Improved performance up to 65% on audio netlists. This commit introduces precompiled static solver code. Due to additional optimizations the compiler can use because the detail calculation steps for the solution are known e.g. the kidniki netlist sees a 100% speed increase. In all environments (windows/*nix/osx) the source for the static solver code can be created using bash lib\netlist\nl_create_mame_solvers.sh. This will create lib\netlist\generated\static_solvers.cpp which is compiled into the mame binary. The script is just a temporary workaround. The intention is that nltool whill be able to create this file with one call. There are other improvements in this commit speeding up the processing of timestep and dynamic calculations.
    . Documented alternative approach to CD4016. The CD4016 is an analog switch IC. Document an experimental approach to implement the analog switch as a 3 terminal element which is completely being dealt with as part as the linear system. The intention was to improve convergence when the switch is in a feedback loop. One example are two-opamp tridiagonal wave generators. Unfortunately the approach did not work out and in addition was performing far worse than the net-separating original code. Also updated comment in nld_generic_models.h.
    . Fixed linking order of netlist. Moved netlist between dasm and utils,expat,... link statements. This fixes the resolution of symbols in netlist code which may be used in machine\netlist.cpp. Changed tested on Ubuntu, Windows and MacOSX. Removed a FIXME in plib\pmain.cpp.
    . Added parameter to split_paragraphs to allow passing in a custom line end string (plib\poptions.cpp). Basename function now accepts a suffix to remove (plib\putil.cpp). Move macros where they belong. Fixed a macro expansion bug. Fixed alternative LM3900 implementations (macro\nlm_opamp.cpp).
    . nltool usage and static compile changes. This commit simplifies the creation of static solvers. For this to happen the following changes were made: nltool does no longer support the "-f netlist_file.cpp" option. All parts of netlist which used the option now expect the file to be specified after all other options. The static compile command now supports an "--output" option to specify the file to be created and accepts multiple input files. To be create the static solver file for MAME use the script provided or: nltool --cmd static --output=src\lib\netlist\generated\static_solvers.cpp. Updated documentation and examples provided by nltool --help.
    . Removed code duplication. Clang-tidy, srcclean and pedantic warnings fixed. Code maintenance on plib\pfunction.cpp.
    . Compile time improvement and code maintenance. Added a define NL_USE_ACADEMIC_SOLVERS and disabled it in the build. This will not compile in solvers which are either illustrative or only perform for large sparse matrices like GMRES.
    . Simplified object structure a bit
    . Code maintenance and edge case fixes. "Edge cases" are compiles were the floting point type used for the core may be different from the one used by solvers, e.g. double/float. This does not happen in MAME, here currently this is always double/double. Since floats are better suited for GPUs whose double performance is limited it was time to review the code. This commit fixes warnings about type conversions and precision loss. In addition there is better support for INT128 and FLOAT128. The MAT solver has seen some minor performance increases.
    . Fixed a segfault happening only under for certain netlists (netlist\nl_setup.cpp). This seems to be a compiler/standard library issues.
    . Documentation update (netlist\documentation\mainpage.dox.h, primer_1.dox.h and test1-50r.svg)
    . Documented trapezoidal capacitor integration (netlist\analog\nld_generic_models.h)
    . Improved readability. The purpose is to make clear what is actually done and to reduce usage of calls to update.
    . Unify solver calls. Calls to the solver used different paths. These changes unify these calls and provide a common call for discontinuous state changes on analog components (change_state).
  . Epson RTC-65271 RTC: Added intrq_r method to query interrupt state. Use existing interrupt flag for intrq_r (machine\rtc65271.cpp).
  . Floppy: Save INTRQ and DRQ states (machine\wd_fdc.cpp). Case of the missing floppies solved (isa\fdc.cpp).
  . Hitachi HD63484 ACRTC: Simplified and unified handlers. The actual bus interface makes no provision for the upper/lower byte masking performed by the previous implementation.
  . MC6850 ACIA: Prevent transmission of a spurious character following master reset
  . Microchip PIC16: Added PIC16 generic disassembler with extended instructions (tools\unidasm.cpp)
  . MOS 6551 ACIA: Clear IRQ state upon hardware reset. Not doing this at device_start time avoids a race condition in digel804 that was causing the Z80 interrupt to be raised in advance of machine_start.
  . Namco Custom
    . Namco custom chip improvements. Wire up reset lines on Namco custom chips. Removed debug logging.
    . Emulated Namco 51xx via low level cpu. Previously, this was using high-level emulation. This had some game-specific hacks.
    . Emulated Namco 06xx the NMI and chip select lines more accurately. Three control bits are used for the clock divider. Clarify timer delay is zero.
    . Fixed MB88xx MCU interrupt handling. m_nf is basically the IF flag. It should be set when the int line is active (when its low). Only trigger an int when the line was previously high.
    . Removed quantum hacks in galaga and polepos. With the better Namco custom chip emulation, this doesn't seem to be required anymore.
  . PC hardware: Fixed faulty EOP propagation that broke floppy disk loading (machine\genpc.cpp)
  . PCI: Fixed 'Fatal error: install_ram_generic: In range cdcdcdcc-9b9b9b98 mirror 0, start address is after the end address' for pcipc in devnoclear debug builds (machine\pci.cpp).
  . PLA: Allow reparsing after device started (machine\pla.cpp)
  . Taito Ensoniq Sound System: Removed obsolete workaround for M68000 reset issue (audio\taito_en.cpp)
  . Taito TC0030CMD (C-Chip): Fixed typo in taito_cchip_device (upd7811->upd78c11)

- Dirt Dash: Mark pointroms as bad
- DoDonPachi III: Added redumped sprite rom b04401w064.u1. NOTE: b04401w064.u1 on all the other ddpdoj sets was found to be corrupt (doesn't match checksum on ROM) this was redumped and replaced in the sets, exept for in the bootleg set, which is based around the corrupt dump.
- Drift Out: Updated clocks and rom labels for clone Drive Out (bootleg). Added UM5100 voices.
- Express Raider: IRQ cleanup
- Filetto: Identified UM5100 sound chip control ports (8923S-UM5100 is a HC55536 with ROM hook-up). Added UM5100 voices.

- Great Swordsman
  . Decapped, dumped and hooked up AA-017 microcontroller, fixes coin handling. Confirmed microcontroller roles/locations.
  . Updated clone Great Swordsman (Japan?) with new AA-017 dump and updated notes.
- Gun Fight: New netlist-based audio implementation for Gun Fight, derived from Midway audio schematics. Sound checked against several YouTube videos and seems to match, apart from acoustic effects of cabinet. Removed the old sample-based sound, which is no longer necessary (The samples for that version were actually from the newer game Boot Hill and didn't match Gun Fight's sound hardware; they even included Boot Hill's funeral march tune!). Although the netlist version has much greater overhead, performance is still acceptable on modern hardware.

- Description changes of Big Run (11th Rallye version, Europe?), Elevator Action (EA, 5 PCB version, 1.1), Elevator Action (BA3, 4 PCB version, 1.1), Front Line (FL, 5 PCB version), Jumping Break (set 1), Kick Off - Jaleco Cup (Japan), Kick Off - World Cup (bootleg), Magic Bomb (Ver. BR4.4), The Mah-jong (Japan, set 1), Missile Attack (U.Games bootleg of Missile Command), Pac Man (U.Games bootleg of Puck Man), Pocket Gal (Yada East bootleg), Route 16 (Centuri license, set 1), Route 16 (Centuri license, set 2), Route 16 (Centuri license, set 3, bootleg?), Space Invaders Part II (Taito, bigger ROMs), Super Contra (set 1), The Tin Star (TS, 5 PCB version) and The Tin Star (A10, 4 PCB version)
- Renamed (elevator) to (elevatora), (elevator4) to (elevator), (franticf) to (franticfa), (frontlin) to (frontlina), (mooncrstu) to (mooncrstuu), (route16a) to (route16b), (route16) to (route16a), (tinstar) to (tinstara), (tinstar2) to (tinstar), (turbod) to (turboe), (turboc) to (turbod), (turbob) to (turboc), (xmen) to (xmenu) and (xmene) to (xmen)
- MAME
  . VIDEO RENDERING SYSTEM: Initialization outer box darkened/less distracting (emu\render.cpp)
  . MEMORY SYSTEM: Fixed memdump command causes MAME crash (MAME 0.209: Removed obsolete alignement limit (emu\emumem.cpp) and correct start/end on big endian (emu\emumem_mud.cpp)) (ID 07560). Removed obsolete logging (emu\emumem_hedw.ipp).
  . ROM loading cleanup: More flexible constructors for path_iterator and emu_file. More straightforward system/device ROM loading and software loading when using ROM loader. Proper parent walk when searching for identical CHDs with different names from software list. Fixed hangs if software item parents form a loop. Fixed layouts being loaded from bogus empty paths. Note that there are changes in behaviour: For software list ROMs/disks, MAME will now search the software path before searching the machine path. The search path for the owner of the software list device is used, which may not be the driver itself. MAME will no longer load loose CHDs from the media path - it's just too unwieldy with the number of supported systems. MAME will no longer search archives above the top level of the media path.
  . DEVICE
    . Eliminated pulse_input_line_and_vector (emu\diexec.cpp; cvs.cpp, galaxold.cpp, scramble.cpp and zac_2.cpp)
    . Don't clear the input queue on reset (emu\diexec.cpp). This fixes problems where devices are input line changes are missed because a device was reset. One case is at startup, where one device's output is wire to another's input. During start the first device adds, eg, a RESET assertion to the second. When that device starts, it resets itself and clears the pending RESET assertion.
  . LUA engine: Enhancing LUA video:begin_recording() function with optional format parameter.
  . Get rid of a temporary that clang 10 doens't like (emu\mconfig.h)
  . UI
    . Removed auto pause (ui\about.cpp). NOTE: Inconsistent with other Tab menu entries including the fullscreen popup for selecting new machine, and also a bug where it refuses to unpause when closing About popup with Tab.
    . Removed clock freqs trailing 0s on machine info screen (ui\devopt.cpp and info.cpp)

  . Programmable Logic Device (PLD): New device for jedutil and rom name changes: Initial support for viewing the logic equations of the PLS100, 82S100, PLS101 and 82S101. Added support to view the the logic equations of the PALCE22V10 device. Improved the documentation on the Magix game and the undumped PAL's (security fuses blown). Added PAL22V10 as another device that is equivalent to the PALCE22V10 device. Added initial registration test for the PALCE22V10/PAL22V10 devices. Adding PAL22V10 combinatorial regression test data. Updated jedutil with a new command that will take a JED file and list the devices that the JED file could represent.
  . Work around deprecation warning - Removing something in 3.9 when the replacement was only added in 3.2 is typical of Python's disregard for stability (scripts\build\msgfmt.py)
  . Added template save/load code (emu\save.cpp)
  . attotime::zero is not a valid arugment for as_hz et al (emu\attotime.h)
  . Re-Implemented SHA-1 and get rid of the two third-party implementations (util\hashing.cpp)
  . Reduced dependencies on libemu (lib\formats\*.cpp)
  . Software List: Start adding validation for data areas (emu\softlist_dev.cpp). Fixed the errors found by adding validation to software list data areas. Most of them seem to be simple copy-paste errors hidden by the fact that the default device_image_interface loader ignores the data area size (as opposed to the "ROM" loader). Validate ROM labels.
  . Fixed smartquotes by disabling them: While smartquotes are somewhat configurable, it's better if we don't use them at all. Makes sure there are no hidden pit traps for the users (docs\source\conf.py).
  . Fixed assert when starting empty driver - the empty driver magically has no search path, and hence can't have any ROM data regions (emu\drivers\empty.cpp)
  . hiscore.dat update (plugins\hiscore\hiscore.dat)
  . Refactoring of AVI/MNG recording code: Initial refactor of AVI/MNG movie recording, consolidation of copy and paste code, hiding of AVI/MNG behind interfaces. Extracted recording specific code out of emu\video.cpp and put into emu\recording.cpp. Took the opportunity to move slightly more logic out of video.cpp into recording.cpp. Consolidated frame counting logic.
- MAC OS X
  . Use Arial Unicode MS as the default font (fixes missing glyphs in many layouts) and fixed deprecation warnings
  . Avoid crashing in OS X debugger when a nonexistent disassembly or memory view is selected (which may happen automatically with .cfg files)
- VGM player
  . Added multiple spectrogram visualization modes (sound\vgm_visualizer.cpp). Fixed DC offset issue and added more visualization modes.
  . Added rate controls and hold button (drivers\vgmplay.cpp)
  . Added recent Project2612 releases consisting of many New and Updated entries (hash\vgmplay.xml)
- Compiling
  . Removed last remaining uses of generic_space() and many dummy_space() calls
  . Fixed some Clang-tidy-10 warnings
  . Revert "Fixed some modernize-use-equals-default clang-tidy warnings" from MAME 0.218
  . Fixed hang with Emscripten's "upstream" backend (scripts\genie.lua)
  . Fixes for Clang 10.0.0 misleading indentation and XOR used as a pow warnings (src\3rdparty.lua, cpu\z8000\z8000ops.hxx and machine\stvcd.cpp). Fixed VS2019_Clang with LLVM 10.0. Fixed stray character (src/3rdparty.lua).
  . Centralised instantiation of more of the util::strformat engine (util\strformat.cpp)
- Debugger
  . Fixed some deprecations (debugger\qt\debuggerview.cpp)
  . QT debugger: Added '#define horizontalAdvance width' to QT debugger (debugger\qt\debuggerview.cpp and memorywindow.cpp)
  . Misc fixes for bugs that showed up in devnoclear debug builds (cpu\lr35902\lr35902.cpp/h, machine\ds1994.cpp, tc009xlvc.cpp, drivers\megaphx.cpp, machine\inder_sb.cpp and taitosjsec.cpp)
  . Make expressions octal for applicable address spaces in disassembly view. General cleanup (debug\express.cpp, debugcpu.cpp): Changed default base from hardcoded macro to dynamic parameter for parsed_expression. Changed symbol table parameters and variables to references or std::reference_wrapper. Removed the (unused) ability to construct a parsed_expression without a symbol table. Eliminated symbol_table &table and void *memory_param arguments from callbacks (superfluous now that std::function can bind everything necessary). Eliminated globalref pointer from symbol_table. Added explicitly defaulted move constructor and move assignment operator.
