- CPU
  . Dynamic Re-Compiling
    . Implemented asmjit emitter (cpu\drcbex86.cpp and drcbex64.cpp). Consolidated many helpers. Corrected previously reported bugs (cpu\drcbex64.cpp).
    . Fixed logging problem (cpu/drcbex86.cpp and drcbex64.cpp). Implemented asmjit emitter (cpu\drcbex86.cpp).
  . Hitachi HD6309, KONAMI CPU and Motorola MC6809: Fixed ASR8 and ASR16 opcodes. Still perform an IRQ acknowledge cycle on software interrupts (cpu\m6809\base6x09.ops). Fixes (MESS) Fairlight CMI IIx memory-map diagnostics.
  . Intel XScale PXA255: Added preliminary support for RTC, clock and power management registers. Correct PXA255 CPU ID. Added placeholder devices for PXA250 and PXA270.
  . Kawasaki Steel KL5C80A12: Emulated MMU within CPU device. Internalized internal RAM and clock divider. Updated notes.
  . MIPS-III: Removed depricated DRC flag and added a flag to disable intrablock branching (cpu\mips\mips3drc.cpp and mips3.h)
  . MOS Technology 6502: NMI is edge triggered, fixes (MESS) Intelligent Chess.
  . Motorola MC68000: Eplicitly set rounding mode for FREM opcode (m68000\m68kfpu.hxx)
  . Toshiba TMP95C06x: Fixed MAX instruction (tlcs900\900tbl.hxx)
- SOUND

  . ICS2115 WaveFront Synthesizer: Improved envelope behavior and debugging registers. Fixed ramping.
  . K007232 PCM Controller: Updates and cleanup. Use device_memory_interface for fetching sample. Fixed frequency behavior. Allow dynamic clock changes. Use shorter/correct type values. Simplify update routine.

- DEVICE
  . 3dfx Voodoo Graphics
    . Disabled backbuf debug key (L), it interferes with player 3 default controls
    . Only flag texture controls as changed if they are actually changed (video\voodoo.cpp).
    . SSE use shift left by 8 instead of floating point multiply by 256 for perspective correction calculation (video\vooddefs.ipp and voodoo.h).
    . Fixed outdated missing MAX macros used for statistics (video\polylgcy.cpp). Added checks for bilinear filter vector routines (emu\validity.cpp).
  . 6821 PIA: Guard against side effects when these should be disabled (machine\6821pia.cpp)
  . 8042 Keyboard/Mouse Controller: Generate data for mouse only if mouse is enabled. Now it is possible to use the (MESS) Nvidia nForce PC BIOS setup without it crashing.
  . Discrete Netlist
    . Code maintenance. Decreased use of reinterpret_cast. Changed some defaults for better TTL game optimization. Various code cleanup.
    . Include file refactoring. The purpose of this ongoing exercise is to remove unnecessary dependencies in header files. Netlist implementations should only have access to what they need. The same applies to device implementations. Core stuff will be moved to the core subdirectory going forward.
    . Fixed 74377 pin assignment. Fixed parameter value resolution on rom devices. Also simplifiy a return. Documented parameter value resolution.
    . Added hints for outputs not connected. Logic and analogue outputs can now be flagged as "NC" (not connected). Example: "HINT(IC13.4, NC)". This will suppress info messages to be logged. The HINT must apply to an existing terminal. HINTs for non-existing terminals are treated as fatal errors. Terminals and logic inputs not connected are still treated as warnings. These need though and a proper fix.
    . Fixed crash on Windows when freeing netlist objects (plib\palloc.h). Fixed static_assert warnings at the origin (plib\palloc.h and pmatrix2d.h). Rework hints to broaden their use and fix NC hint. Use NC hint for 74377. Fixed debugging in MSVC (plists.h). Moved everything not needed by netlists from nl_setup.h into core/setup.h. Fixed some Clang tidy warnings.
    . Added comparison operators to plib\pfunction.cpp. Comparison operators evaluate either into 0.0 or 1.0. Thus they can be used like "(a==1)*(b==2)" which will only result in 1.0 if a equal 1 and b equal 1.
    . Added log() to plib\pfunction.cpp. Added parameter to varclock (devices\nlid_system.h). Align design VARCLOCK to AFUNC (devices\nld_system.cpp). Added more constructors and () operator to plib\pfunction.h.
    . Added progress indicator to nltool. When running a netlist "--progress" may be used to display a progress indicator. Fixed pfunction if. The if postfix evaluation corrupted the stack. Fixed polarity of 74LS125 tristate input.
    . Added basic unit testing support. Added google test syntax compatible unit testing support. This is a very limited subset of the google test framework and not intended ever to be a replacement. Adding a dependency to google test for the functionality required was considered to be an overkill. nltool -c tests runs unit tests if linked in. This is *not* the case for the version of nltool compiled with TOOLS=1. Added unit tests for plib::pfunction.
    . Removed soft reset support. Electronic circuits and base components like resistors or capacitors do not have a reset line. You can use them to create reset circuits. There is thus no point to support soft reset, the equivalent to pressing the reset button. Fixed some bugs around reset and start up logic. This also fixes the "scramble F3" crash.
    . The pfunction now supports unary minus operators. Updated documenation on noise sources. The pfunction supports unary minus and removed duplicate code.
    . Removed some warning suppression from netlist\build\makefile. Fixed signedness warnings in ptime.h.
    . Unit test macros now have a "P" prefix. Will allow to use both googletest and Catch frameworks. On unexpected std::exception include what() in error message.
    . Added 74113, 74121 and 74157 devices and refactor 74123 code. Migrated DIP devices to netlist devices. Refactor code to be based on device description structs. Fixed 74121 clocking logic.
    . Improved dealing with non-convergence situations. No changes for well-behaved netlists. Netlists reporting "newton loops exceeded" messages should now report a lot less of these messages. In case newton-raphson does not converge, netlist will reset the state back to the beginning of the timestep. It will than use a number of very small timesteps to hopefully deal with the non-convergence due to a too big timesteps. Afterwards solving continues using dynamic timestepping until the time-slice is complete. This is a lot better than the previous approach. This is meant as a performance optimization helper. Ideally, your netlists never produce "newton loops exceeded" messages. Any events for connected analog and digital inputs will happen after the timeslice is complete. Thus this approach - as the previous one - are not suited for high-frequency (such as video outputs) situations. In these case, only dynamic timestepping or reducing the fixed timestep are a suitable solution.
    . Use threads on netlist logs. This significantly increases the performance of output/terminal logs. Added a psemaphore class to pmulti_threading.h.
    . Fixed power pin names for CMOS devices. For truthtable cmos devices the power pin names will now be set according to the logic family. Fixed some issues for CD4538. Changed "already connected" warning to info level. Some ICs (CD4538) connect pins internally to GND and the schematics again externally. This will cause this info to be printed. The warning now is a lot more verbose.
    . All inputs now explicitly specify a signal handler: Currently devices use the "update" function if no handler is given for an input. For this to work the update function has to be virtual. This will cause issues on shared execution schemes like CPU/GPU using NVCC. This is the first batch of changes to ensure that handler resolution is static.
    . Emit a warning every 100 invocations of Newton Raphson resolution (solver\nld_matrix_solver.cpp)
    . Always take power pin names from logic family. Default NMOS power pins to VCC and GND. MOS uses VDD/VSS - update gamemachine netlist.
    . Reduced overshoot impact on NE555 astable frequency: If TRIG and TRESH are connected overshoot compensation will be enabled. The approach is raw but delivers results (at 5 to 10 steps per discharge/charge) within a couple of percent. Please take into account that any datasheet formulas are idealistic. Neither capacitor, resistor, internal resistor tolerances are taken into account. Nor are ambient temperature and chip temperature.
    . Fixed Inductor state saving (analog\nlid_twoterm.cpp). Code maintenance: More handler alignment. Dead code removal. Removed update calls which do nothing. Comment out empty reset and update calls.
    . Avoid NE555 oscillation due to overshoot compensation. Fixed Clang error: No matching constructor for initialization of 'analog::nld_twoterm' (devices\nld_4066.cpp).
    . Prepare road towards trapezoidal integration. This is a long term transition goal. Documented in source (see NL_USE_BACKWARD_EULER).
    . Potential regression trigger: Removed update and NETLIB_UPDATE completely. Startup initialization order may change. This may cause regression tests to trigger. This is expected. Logic TTL devices do not have a defined power-up state. That's why reset circuits exist which create a reset signal *after* all power supply lines are stable.
    . Include timestamp in newton-raphson loop warnings (solver\nld_matrix_solver.cpp). Fixed logging of final timestamp (devices\nld_log.cpp).
    . Added netlist simulations for the following games: Armor Attack, Barrier, Boxing Bugs, Rip Off, Solar Quest, Space Wars, Speed Freak, Star Castle, Star Hawk, Sundance, Tail Gunner, War of the Worlds and Warrior. Removed previous samples-based sound.
    . Modernized 74164 and 74393 netlist TTL devices
    . nld_matrix_solver is now owned by nld_solver. Added frontier documentation (devices\nlid_system.h).
    . Rewrote scheduler scheduling: All solver scheduling is now handled by nld_solver. Previously, for dynamic timestepping the sub solvers would be responsible for their scheduling themselves. This prevented any attemps to use parallel execution of solvers. Now the route is free towards experiments to use parallel execution of solvers. Uses ptimed_queue_linear in solver scheduling. Improved netlist queue implementation (template now). Added const delegates and subsolver stats. Removed dead code.
    . Separated nl_base.h into separate header files. This clean-up exercise will hopefully make it easier to navigate the core code. Another long term goal is to further straighten the object model.
    . Include GMRES solver in build. The GMRES solver for larger matrices (>>100) can outperform Gaussian elimination. Including it so it gets wider attention. As far as I know netlist is the only SPICE-like circuit simulation providing a GMRES solver.
    . Sub solvers now have their own parameter set. Example: PARAM(Solver.Solver_0.METHOD, "GMRES"). Will use the GMRES solver instead of the default MAT_CR solver. Same applies to all Solver parameters. Please use with care. If you change your netlist (e.g. using frontiers) the allocation of nets to solvers and the number of solvers may change. Thus this type of tweaking should only be used after the netlist completely works.
  . Floppy
    . Fixed spinup on interrupt command. Do not RESTORE at reset WD1770/72 (machine\wd_fdc.cpp).
    . A single missing sector was causing it to give up on an images, as incompatible. Being a little more permissive here helps working with some old recovered disk images with some lost sectors (formats\wd177x_dsk.cpp).
  . Imagetek I4100 052 VDP: Partially fix flip screen. Fixed sprite position, tilemap offsets and glitches in Hyper Duel.
  . Intel 8255 PPI: Set ibf flag in output mode for port A
  . MC6840 PTM: Fixed a couple of issues related to the T3 divisor
  . Printer: Initialized the data output high. High is the restful state for RS232. The low level could cause continual breaks to be received by an attached device and this could cause problems for some drives (bus\rs232\printer.cpp).
  . Sound Blaster and Game Blaster Sound Card: Fixed SAA1099 output and clock inputs (verified from real hardware)
  . V3021 RTC: Support serial interface. Implemented RAM and address commands. Use device_rtc_interface for RTC handling (machine\v3021.cpp).
- aleck64.cpp: Modified burn_cycles method (machine\n64.cpp)
- bigkarnk_ms.cpp, bloodbro_ms.cpp, galpanic_ms.cpp, raiden_ms.cpp, splash_ms.cpp and toki_ms.cpp: Minor improvements. Misc work on sprites for Raiden (Modular System).
- cave.cpp: Use gfxdecode for sprite decoding. Use generic gfx layout for 4bpp tilemap. Reduced duplicates and unnecessary values.
- cinemat.cpp
  . Added netlist simulations for the following games: Armor Attack, Barrier, Boxing Bugs, Rip Off, Solar Quest, Space Wars, Speed Freak, Star Castle, Star Hawk, Sundance, Tail Gunner, War of the Worlds and Warrior. Removed previous samples-based sound, fixes (ID 02603), (ID 03307) and (ID 03720).
  . Added built-in minimal artwork for Warrior. Decreased noise level in Space War and Barrier to allow filtering to kick in.
- ddenlovr.cpp: Replaced Z80 CPU1 with 'Kawasaki Steel KL5C80A12' in Mahjong Daimyojin and Mahjong Momotarou
- exidyttl.cpp
  . Death Race roms 36 and 35 were corrupt, fixed with correct images from clone Robot Hunting (bootleg of Death Race). Added note about format of image 36 [Frank Palazzolo].
  . Clone Robot Hunting (bootleg of Death Race) roms now match Death Race 100%. Driver now uses Death Race rom images.
  . All Demolition Derby 512 byte roms were set to length 256 (incorrect length). Some upper bits in nibble-wide roms were not set to default zero.
  . Added newly dumped Destruction Derby roms from Exidy PCB, images now match fixed images from Demolition Derby (expected). Redundant with Demolition Derby in chicago.cpp, but it is a different PCB layout and different company.
- goldnpkr.cpp: Clean-ups, fixes, updated links and a new addition.
- gotcha.cpp and zerozone.cpp: Minor cleanups
- hng64.cpp: Emulated MMU in KL5C80A12 CPU. MMU handling in HNG64 has been moved to the core; the rest is not implemented yet.
- hyprduel.cpp
  . Fixed sprite delay
  . Fixed Imagetek I4100 052 VDP glitches in Hyper Duel
- megaplay.cpp: Added 5x motherboard PLDs
- midzeus.cpp
  . Moved some Zeus2-specific members into the appropriate subclass and added more state registration
  . Added skeleton devices for the IBM 21S850 IEEE 1394 PHY controller and the TI TSB12LV01A IEEE 1394 link-layer controller. 'The Grid' no longer hangs. Added skeleton IBM 21S850 IEEE PHY support, hooked it up in midzeus2 to accurately reflect the PHY model used.
- nemesis.cpp: Fixed VLM5030 speech at least halfway in TwinBee (gx400_speech_w; drivers\nemesis.c) (ID 07537)
- pgm.cpp
  . Simulated 'Photo Y2K 2' sprite offset decode (machine\pgmprot_igs027a_type1.cpp) (Game now playable). Support for V3021 RTC serial interface. Implemented RAM and address commands. Use device_rtc_interface for RTC handling (machine\v3021.cpp).
  . Use struct for sprites and raw parameters for screen. Fixed timing of intro sequences in some games. Use generic gfx layout for foreground. Moved VBlank IRQ into screen_vblank. Reduced duplicates. Added notes.
- photon.cpp: Cleanup
- seattle.cpp and vegas.cpp: Fixed 8 way and 49 way joystick selection on Vegas and Seattle drivers (ID 07340)
- segas18.cpp: Fixed controls do not work in Laser Ghost and Wally wo Sagase! (ID 07708)
- sigmab98.cpp
  . Eliminated hack to force starting PC. Changed Sammy medal games to use KL5C80A12 CPU device with proper MMU emulation (animalc, gocowboy, haekaka, itazuram, pyenaget and tdoboon).
  . Execute enough of the Sammy medal game BIOS to initialize things properly. Split up driver state class.
- taito_l.cpp
  . Removed old rombank debug logging
  . Fixed Fighting Hawk rombank mask, fixes background graphics garbled (ID 07696).
- tigeroad.cpp: Minor cleanups
- tourvis.cpp: Added BIOS V4-54

  . Added default port mapping for 8WAY players. Fixes a crash in Road Burners caused by trying to read undeclared io ports. Set default ioport IN2 to IPT_UNUSED for analog games.
- midyunit.cpp: Cleaned up the banking on the Williams System 11 Background Sound/Music board device to support banking up to 27c010 sized EPROMs, which are used on the prototype Funhouse pinball and on High Impact Football on Midway Y-Unit hardware. Added more notes about the operation/hookup and variants of the System 11 Background Sound/Music board.
- 18 Holes Pro Golf: Documented differing opcode in clone (set 2) which causes the wrong ball positioning
- 280-ZZZAP: Improvements to 280-ZZZAP netlist audio. Noise-based sound effects corrected. The original strength of the zener noise voltage was about three orders of magnitude too low for the current being passed through a zener of this type. This prevented the noise generator from working as designed and made the noise far too weak for the noise-based sound effects to work properly. Those effects now sound much closer to the real hardware. Implemented faster high-level emulation version of noise generator (Credit to Couriersud for suggesting this). The corrected noise voltage made the component-level emulation of the noise generator much too demanding on the minimum timestep needed to produce accurate results without unrealistic voltage spikes, and so will not run accurately at reasonable emulation speeds. But by replacing it with a simple but effective AFUNC()-based comparator, we get a functionally similar noise signal generator that produces effectively identical output while still being able to run with 48 kHz static timestepping. So we get both decent emulation speed and correct-sounding noise effects. Added output voltage clipping on post-crash sound to remove voltage spikes, resulting in a smoother, more accurate sound (Credit to Aaron Giles for suggesting this clipping method). Changed output to be taken from second LM3900 output opamp (inverted signal) for smoother waveform and better tone quality. Added master volume potentiometer which can be user-set, set to midpoint by default. Adjusted output scaling and offset to match. Various explanatory comments expanded or corrected.
- AGEMAME
  . Added AY8913 sound chip back to MPU4Video boards to fix the 'lock in warning' sounds in The Crystal Maze. Adjusted internal layouts to fix ESCAPE button alignment.
  . Adjusted clock speed of sampled sound board in 'The Mating Game' and clones, fixes playback. Adjusted inputs to match reports in test mode
  . Fixed some clone relationships in v4mazbla, v4psi14d, v4psi20d, v4psi214, v4psia, v4psib and v4tetrs1.
  . Allow 'Strike it Lucky (v0.5) (MPU4 Video)' and 'Barquest (v2.6d) (MPU4 Video)' to decode questions
  . Protection workarounds to get more games showing video
  . Basic layout and input tweaks to v4addlad
  . Hookup joystick interfaces to Tetris Payout and Prize Space Invaders
  . Added inputs and layout for Strike it Lucky. Corrected inputs for Adders and Ladders.
  . Added support for simple LED extender to mpu4.cpp driver 
  . Added inputs and layout for Barquest and Barquest 2, added DIL switches to Prize Space Invaders and Prize Tetris. All games in this driver now default to a common set of inputs for easier discovery (drivers\mpu4vid.cpp). Corrected typo in logger (machine\mpu4.cpp).
  . Added payout shelf opto to Prize Space Invaders
  . Start to untangle and split apart and properly identify some mpu4vid sets now that they boot. There's nothing actually new here, despite it appearing that there are a lot of new clones and new sets, they're just the result of finally being able to identify some things properly, work out what belongs where, and gain a better understand of what is missing - some things were in entirely the wrong drivers, or paired with the incorrect ROMs.
  . Tweaks to some MPU4 Video inputs
- Block Gal: Partial DIPs fix (ID 07702)
- Bosconian: Sprites have a lower priority than background (video\bosco.cpp)
- Captain Silver: Redumped and verified the i8751 MCU
- Dobou-Chan: Moved game from BishiBashi to KonMedal68k driver, GFX are mostly corrected.
- Double Dragon: Modified clone Double Dragon (bootleg with 3xM6809, set 1) machine config to actually reflect what's on the PCB
- Escape from the Planet of the Robot Monsters: Fixed game freezes upon end of demonstration (ID 07691)
- EuroPlay 2001: Added new motherboard BIOS
- Four Trax: Fixed default gearshift binding
- G-LOC Air Battle: Dumped drive board rom
- Gun Fight: Multiple improvements to Gun Fight netlist audio: Model for transistors adjusted, replacing default NPN transistor model with a high-gain NPN transistor type that more closely resembles those used by the real Gun Fight sound circuits. This has a quite obvious effect on the shot sounds, and it seems the circuits were designed for this effect. Made all volume potentiometers user-adjustable; previously fixed at 50%. Replaced abstract model of noise generator with component-level one, including a model of the generator's zener diode. Zener noise is provided by an associated Gaussian white noise source running off a 48 kHz clock. Both the zener diode and Gaussian white noise source are component models recently added to the netlist library. Supply voltage to amplifying transistors tweaked downward from 16.5 volts to 16 volts, determined by properly analyzing power supply circuit and confirmed with a documented reference. Much more commentary describing the sound circuits' function and modeling issues.
- IGMO: Added color prom, palette is now correct.
- Image Fight: Dumped i8751 MCU
- King Derby: Fixed debug assert in clone Cow Race (King Derby hack) (ID 07690)
- Lethal Crash Race: Minor cleanups
- Mahjong Senka: Decrypted game, gets in game but glitches heavily.
- Mortal Kombat: Fixed sound and added PAL dumps to clone Mortal Kombat (Yawdim bootleg, set 2)
- Moon Cresta: Merged Sirio II (Calfesa S.L. Spanish Moon Cresta bootleg, set 1), Sirio II (Calfesa S.L. Spanish Moon Cresta bootleg, set 2) and a third dump in a single correctly dumped set 'Sirio II (Calfesa S.L. Spanish Moon Cresta bootleg)'. All three had corrupted ROMs.
- PinMAME
  . Switch all the pre-WPC Williams pinballs to using io port arrays for their switch matrix, which gets rid of runtime lookups and fixes MAME crashes if a value with more than one bit set is written to the column select (drivers\s3.cpp, s4.cpp, s6.cpp, s6a.cpp, s7.cpp, s8.cpp, s8a.cpp, s9.cpp, s11.cpp, s11a.cpp, s11b.cpp and s11c.cpp).
  . Fixed old copypaste mistake (m_pias->irqa_handler() --> m_pias->irqb_handler(); drivers\s8.cpp, s8a.cpp, s9.cpp, s11.cpp, s11a.cpp and s11b.cpp). Added override for all early williams pinballs.
  . Switch William system 11/11a/11b/11c pinballs to use input_merger for the maincpu and audiocpu IRQ inputs, and rewrote the timer IRQ generator to be more accurate vs hardware. Fixes the advance and up/down operator inputs, and may make certain games more stable.
  . Make drivers\wpc_dcs.cpp and wpc_s.cpp class definition style more consistent with the other Williams pinball drivers
  . Williams System 11/11a/11b/11c pinballs: Further consistency fixes with device and function names, more fixes (missed a few earlier) relating to the CVSD speech clock polarity and digital input bit masking, and corrected some memory/device mirroring issues to be consistent across the drivers.
  . Williams System 11C "background" Audio Board: Added PIA portb and cb2 write callbacks and synchronize fences, and hook them up, this fixes the "MUSIC ERROR" and various bg-music feedback-triggered sounds in Williams System 11C pinballs, i.e. the "song" in Dr. Dude works correctly now. This is also preparation for renaming this device to "Williams D-11581 Audio Board" as the same PCB is also used on some Midway Y-unit arcade games, some Williams System 11A pinballs and all Williams System 11B pinballs (except Jokerz), not just on Williams System 11C pinballs. Added notes to Williams D-11581 Audio Board device.
  . Williams System 11B: Switched to use the Williams D-11581 "Audio Board" device instead of its own implementation. Document the switches needing to be held to get in-game in all of the System 11B pinballs. Fill out the remainder of the System 11B switch matrix to allow all 64 possible switches to be hit.
  . Fixed the input matrices in Williams System 11/A/B/C and the WPC Alphanumeric drivers, so all possible inputs can be triggered with keyboard keys. Fixes lack of coins (which are mapped in a non-standard location) in the WPC versions of Dr. Dude. Add some notes about the WPC S11 sound interface adapter board used by WPC version of Dr. Dude and the prototype version of Funhouse.

- MAME
  . VIDEO RENDERING SYSTEM
    . Properly clean up d3dintf (render\drawd3d.cpp)
    . More lenient with resizing very large views in windowed mode. Reduced minimum window height (osd\windows\window.cpp).
    . Added default flags parameter in draw function (TILEMAP_DRAW_ALL_CATEGORIES; emu\tilemap.h)
    . Don't add parent set external artwork if artwork found (emu\render.cpp)
  . DEVICE
    . Removed m_totalcycles workaround (emu\diexec.h)
    . Added workaround for GCC and Clang 8 (emu\devcb.h)
  . UI
    . Able to show emulation warnings from tab menu. Swap order of popup screens (gameinfo first, warnings second) and added "press any key" to gameinfo.
    . Get help from website instead of files that don't exist (mame\clifront.cpp)
  . PLUGINS: Don't save empty configuration files file (plugins\autofire\autofire_save.lua)
  . Validity: Added checks for bilinear filter vector routines (emu\validity.cpp)
  . Device Network Interface: Set default network device to be none to avoid inadvertantly spamming a network (emu\dinetwork.cpp)
  . Updated RTD docs theme to 0.5.0 to fix search box (docs\themes\sphinx_rtd_theme). Preliminary work on -joystick_map redesign. Adjustments to phrasing for analog mapping (docs\source\commandline\commandline-all.rst). Added Health warning text.
  . Enabled save state support in big10.cpp, blackt96.cpp, kas89.cpp, kurukuru.cpp, littlerb.cpp, looping.cpp, lucky74.cpp, luckybal.cpp, namcos2.cpp, sfkick.cpp, srmp6.cpp, supertnk.cpp, tigeroad.cpp and tonton.cpp. Fixed save state support in luckybal.cpp and rulechan.cpp.

  . Switch appveyor GCC build to -O3 (appveyor.yml). Appveyor MSYS2 workaround: Work around appveyor not being able to update MSYS2. There has been a change to MSYS2 package maintainers, meaning that the packages are now signed with a different key:  https://www.msys2.org/news/#2020-06-29-new-packagers. Import the new keys manually until appveyor image is updated with a new msys2-keyring package. Explicitly kill msys2 before the second pacman call (appveyor.yml).
  . Removed superfluous semicolons in various devices and drivers (x();;)
  . Restored some standard library #includes, added some things that were used but not #included and clean up some #include guards.
  . Fixed SOL2 build on GCC 10.2 by working around overload resolution problem (3rdparty\sol2\sol\)
- Debugger: Added debugger command saver for memory region and debugger command loadr for memory region (debug\debugcmd.cpp).

- New Clrmamepro:  https://mamedev.emulab.it/clrmamepro/#downloads
- CPU
  . ARM7: Fixed THUMB ROR behavior for shift values of 0 or >= 32. All tests in FuzzARM (CPU test for Game Boy Advance) now pass (arm7\arm7thmb.cpp)
  . Kawasaki Steel KL5C80A12: Emulated KP69 interrupt controller. Clean up KP69 code a bit. Don't latch masked-out requests. Prepare for device variant. Log kc82 MMU changes.
  . MCS-48: Fixed cycles not deducted for timer IRQ, get rid of (MESS) Kaypro 10 hack. Burn opcode cycles before executing opcode. Get rid of wy100 irq hack. Fixed possible missed timer overflow if burn_cycles is larger than 2. Fixed cond jump address if argument fetch was at 0x7ff or 0xfff (mcs48\mcs48.cpp).
  . NEC uPD7810: Analog fixes (conversion registers, scan mode). Fixed semantics of SKIT NMI and SKNIT NMI. Simplified analog input code.
  . NEC Vxx/V25: Use anonymous namespaces to avoid ODR violations with enums
  . Texas Instruments TMS34010/20: Eliminated pure 8-bit read/write bus accesses (these are always read-modify-write, even if aligned)
  . Texas Instruments TMS34020: Upgraded data bus to 32 bits and add preliminary masking for 16-bit operations.
  . Zilog Z80: Don't continue cpu when halt opcode gets overwritten
  . Zilog Z80180: Correct FRC counting rate and direction. Run programmable reload timer off FRC. Emulated a subtle difference from Z80 behavior in fetching opcode after DD CB or FD CB.
  . Zilog Z8681: Fixed bug in decimal adjust (z8\z8ops.hxx). Fixes PRINT 654 in (MESS) BERT (1987).
- SOUND
  . GI SP0250 LPC: Matched clock divider to real chip measurements. Fixed behavior when not fed enough data; addresses "gapping" in speech in Sega games. Implemented accurate LFR noise generator according to real chip measurements. Added pulse-width modulation DAC output mode for future consumption by netlist. Further verification from real hardware.
  . K054539 ADPCM: Allow side effects. Added imperfect_features related to unverified/unemulated effects and some registers.

  . Sega Universal Sound Board: Improved Universal Sound Board implementation for better accuracy in Star Trek and Tac/Scan (ID 07103). Wrote netlist-based backend for 'Sega Universal Sound Board'; currently disabled due to limitations in the system.
  . Speaker: Added new option -speaker_report  to report clipping and other statistics after each session. This replaces the previous compile-time define and offers more detail.
- DEVICE
  . 3dfx Voodoo Graphics: Disabled debug statistics popup (video\voodoo.cpp)
  . Atari CAGE: Added one missing variable to state saving (audio\cage.cpp), should address MT07724 (No sound when loading from save state in sfrush and sfrushrk).
  . Discrete Netlist
    . Added netlist sound to Destroyer (https://youtu.be/xOxXcZqIoeo), Fire One (https://youtu.be/xOl0NR5in5o), Flyball (https://youtu.be/AaVw4egRCRc), Star Cruiser (https://youtu.be/XwNVSPnM4dQ), Star Fire (https://youtu.be/pOPmgesqO6c), Star Fire 2, Super Speed Race and Tank Battalion (https://youtu.be/Gv5wLv6Ry-o).
    . Added netlist-based sound to Astro Blaster, Eliminator, Space Fury and Zektor.
    . Added netlist for Tank/Tank Cocktail [TTL]. Currently runs at about 0.005% of full speed, unsure why.
    . Fixed building with GCC-10.1 on MinGW32 (machine\nl_palestra.cpp)
    . Removed test code from nld_74125.cpp. Further nl_base.h splitting into headers in core subdir. Fixed a crash if an exception happened during validation (machine\netlist.cpp). Fixed a bug in preprocessor if and elif parsing. Added a missing directive to the file parser. Necessary changes towards runtime processing of macro directory.
    . Source stream refactoring. This is an infrastructure change to enable better error reporting including file/source and line numbers in the future.
    . Added CD4011, CD4024, 7407 and CD4053 devices. Fixed 4011 implementation. Converted CD4013 DIP to macro. Fixed an issue during proxy hookup. Added cd4053 to netlist.lua. Recreated nld_devinc.h.
    . Fixed 74ls629 implementation and some cherry-picking issues. Disable dangerous optimization. This was an over-aggressive optimization. Now prints an info and recommends to comment out if appropriate.
    . Device refactoring: Moved DIPs for 82S16, 82S115 and 2102A devices into nlm_proms. Moved 7448 DIP to a macro. Replaced 7442 with truthtable and macro. Moved 74LS629 DIP into macro. Expand truthtable to handle 10 outputs. Updated 7450, 7473/7473A, 7474, 7475/7477 devices to use DIP macros instead of C++ DIPs. Reworked 7475/7477 more in the style of 7474, leveraging system signal activation and edge detection. Fixed incorrect sense in warning (analog\nld_mosfet.cpp).
    . Added CD4017/4022 devices. Fixed 7492 and roms include bug (devices\nld_7492.cpp and macro\nlm_roms.h).
    . Macro-ized 7483, 7485, 7490, 7492, 7493, 7497, 9310, 9316, 9322, 74107, 74113, 74153, 74161, 74163, 74164, 74165, 74166, 74174, 74393 and CD4006 DIPs.
    . Minor optimization to remove sqrt from inner loop (solver\nld_matrix_solver_ext.h). Moved documentation from header to cpp file: Header files will disappear and only nld_devinc.h which is can be created by nltool will stay. These commits ensure that the documentation is preserved when the header files are deleted at some point in the future.
    . Added example documentation to SN74LS629_DIP (macro\nlm_ttl74xx.cpp)
    . Silence indentation warning in 3rdparty/ under Emscripten
    . Refactored pokenizer. Separated tokenizing and reading of tokens. This enables caching of parsing results on the token level. Implemented caching of token stream. Overall this significantly improves parsing performance (~10x). Next step towards a bare-bone nltool which does not depend on macro devices.
    . Added documentation for devices in nlm_ttl74xxx.cpp. Documentation for all devices in nlm_ttl74xxx now is available in the doxygen documentation.
    . Renamed DM9312 to TTL_9312 for consistency. Added man target to netlist makefile (help2man).
    . Header file separation. Fixed creation of static solvers. Fixed line-number tracking when at end of line.
    . Align naming of files within the macro folder. Use a consistent naming scheme. Improved parsing performance. Preparational work for easier device addition.
    . More include untangling. nl_base.h now basically only includes files from core. All headers in core compile on their own.
    . Untangle sound and cpu devices. Member variables are now where they belong. Avoid over/underclocking of netlist sound devices.
    . Make streams accept logic parameters as well (netlist\nl_interface.h). Added THRESH parameter to AFUNC (devices\nlid_system.h).
    . Added machine.time() rules. Avoid overshooting sound devices, i.e. advancing past machine.time().
    . Fixed elif processing (plib\ppreprocessor.cpp). Removed printf debugging (netlist\nl_parser.cpp and nl_setup.cpp). Also raises error if during parsing a local source is not found (netlist\nl_errstr.h).
    . buffered_param_setter refactoring: Each parameter to set now has a dedicated buffered_param_setter device. This allows different sample times per device. Updated netlist.cpp for new approach. buffered_param_setter is a template. The template parameter is a class which is expected to support the [] operator. The value passed to [] operator is the requested sample number.
    . Regenerated static solvers and fixed errors preventing static solvers from generating
    . Increase queue sizes to accomodate nl_tank complexity (netlist\nl_config.h). Properly fixed 74165 implementation. Fixed MK28000 address latching.
    . Moved dead code into examples/lostfound.cpp. This work didn't improve performance but still may serve as examples for complex truth table implementations.
    . Added compile-time option to record nltool-compatible CSV files. Improved CD4020 implementation. Fixed CD4053 behavior. Added 74139 device. Added TL082 device.
    . Use posix_memalign with ANDROID (netlist\plib\palloc.h). Optimized 74165. Added AN6551 opamp.
    . Added NETLIB_DELEGATE_NOOP(). This should be used for inputs which do not need a handler. Examples are data inputs which are only accessed on a clock change.
    . Removed duplicate device definitions. Use macro DIP definitons for 74175, 74192, 74193, 74194 and 74365.
  . Fixed-Frequency Monochrome Monitor: Improved handling of interlaced video. Will now detect half lines before vsync and determine field (video\fixfreq.cpp).
  . Intel 8253 PIT: Added explicit synchronization to all writes. Cleaned up some timing calculations to avoid double<->attotime conversions. Fixed cycles computation error due to using floating-point.
  . MC68681 DUART: TX/RX clocking from timer fixed and added partial support for break signal.
  . Microtouch Touchscreen: Added BIOS 2.2

- Funny Strip: Decrypted clone Ring Ball. Currently stuck at initialization / test mode.
- Invasion - The Abductors: Marked PIC dump as BAD
- Laguna Racer: Added Laguna Racer to the 280-ZZZAP netlist audio driver, with conditional changes to the netlist for the circuitry differences between the two games. Adjust some netlist components that apparently changed from the 280-ZZZAP schematic to production machines.

- Legend of Hero Tonma: Redumped and verified the i8751 MCU for Legend of Hero Tonma (World)
- Metal Maniax: Probably fixed regression
- Photo Y2K: Added new sprite roms
- PinMAME
  . Separated Williams System 11 BG sound boards into the 5 functionally different types that existed, and hooked the appropriate types to each system 11/a/b/c driver. Switched to using a rom load region with a listed parent:sub space rather than using a set_romregion function within the device for all users of the s11c_bg device. Replaced the embedded bg sound and bg music board emulation on s11.cpp with the appropriate devices. Updated notes for the WPC Sound board.
  . Added and hook up a device for the D-12338-567 Williams Pin Sound '88 board, used on the Williams System 11B 'Jokerz!' pinball. Switched Williams Pin Sound 88 board to use two device_mixer_interface outputs for its output channels, instead of having speakers handled internally to the device. Fixed the Pin Sound 88 /SYNC_PULSE line to connect to Jokerz' System 11B PIA@3400 CA1 instead of CB1, based on board pictures of the W2/W3 jumper positions. Added a note about the infamous audio hum issue on the real Jokerz! pinball table, and updated device comments to clarify things and fix some minor errors.
  . Share the memory maps for the System 11/A/B/C mainboard maincpu and audiocpu between the s11, s11a, s11b, s11c drivers to remove redundant identical copies in each driver. Made the MC1408 dac a member device of the s11 main class to get rid of some init-time tag lookups and prepare for future enhancements. Put the initialization order of devices in the sound-board specific machine configs in a more sane order.
  . Added inputs to Big 40 Poker (BWB).
- Raiden: Added PCB ASCII layout to Raiden (Modular System), added year and promoted from skeleton to MACHINE_NOT_WORKING.
- Renegade: Renegade/Kunio-kun fixes. Reverted 6809 soundlatch IRQ and improved 6502 IRQ timing.
- Revolution X: Manually restored BAD PIC16 dump and hooked to driver (ID 03228). Cleanup security chip access. Use 8-bit handlers for NVRAM, reducing size to 8192 bytes. Eliminated dependencies on Midway T-Unit driver.
- Rodent Exterminator: Added preliminary decryption
- Sega Bass Fishing: Added KL5C80A16 I/O CPU to configuration

  . Added netlist sound. Removed MACHINE_IMPERFECT_SOUND flag (ID 03090).
  . Various fixes and cleanups. Correct CPU and video clocks. IRQ is scanline-based, not coin-triggered. Clean up and modernize VBLANK NMI handling. Added watchdog timer. Verify memory map and add mirrors. Added imperfect colors flag (color PROM usage is now known to be wrong). Increase queue sizes to accomodate nl_tank complexity (netlist\nl_config.h).
- Tank/Tank Cocktail [TTL]: Added netlist for Tank/Tank Cocktail [TTL]. Commented out CPU-choking motor sound for now. Fixed a transcription error. At least partially fixed screen parameters. Attempted to hook up proper timing params, doesn't seem to work. Assorted fixes and changes. For some reason, GNE (H4.6) never goes low at the start of the game.
- Tecnodarts: Added PCB ASCII layout
- Venture: Replaced BAD_DUMP gfx1 rom with verified
- Vigilante: Added PAL and PROMs to clone Vigilante (bootleg)

- MAME
  . VIDEO RENDERING SYSTEM
    . Added getter for pixeltime (emu\screen.h)
    . Fixed overwriting last pixel of previous update and rendering whole scanline when update was called inside hblank.
    . Fixed possible issue if update_now and update_partial are both called from driver (emu\screen.cpp)
    . Clean up the preprocessor glue for selecting RGB utility implementation a little and check macros are defined before doing comparisons (emu\validity.cpp, video\rgbgen.cpp, rgbsse.cpp and rgbutil.h)
  . Removed unsupported setter, emumem enforces unmapval 0 or ~0 (emu\addrmap.h).
  . Fixed audit finding sets that you don't have when: 1. A clone has a rom that hasn't been dumped but it has the same name as a rom in the parent that has been dumped. 2. If roms are the same between parent and clone but loaded differently (ID 05556). 3. If parent has all the roms in the clone & you have neither set but you have a device rom that is used (ID 07410).
  . Added widescreen layouts for working machines with shifters: 280-ZZZAP, Buggy Boy Jr/Speed Buggy, Buggy Challenge, Change Lanes, Chase Bombers, Chequered Flag, Cisco Heat, Continental Circus, Destroyer, Double Axle, Enforce (Japan, Analog Controls), Final Lap, Grand Champion, Grand Prix Star, Laguna Racer, Namco System FL, Outrun, Pole Position, Power Drift, Rad Rally, Speed Freak, Speed Race, Stocker, Top Racer, Top Speed, Turbo Tag (Prototype) and WEC Le Mans 24. Added widescreen layouts for non-working machines with shifters: Round-Up 5 - Super Delta Force, Spy Hunter (bootleg on Tecfri PCB), and Over Drive.
  . Cleaned up save/load state menu code. Fixed display names for states saved with keyboard keys. Wait for at least one frame with no keys pressed before saving/loading.
  . hiscore.dat update (plugins\hiscore\hiscore.dat)
- MAC OS X: Pass FORCE_C_DRC_BACKEND=1 on ppc architectures: PowerPC architecture is special in a way that it has some inline assembly code but no DRC support. As a result, NOASM=1 was never configured. In contrast to the old DRC, asmjit only compiles on the architectures it supports. FORCE_C_DRC_BACKEND=1 needs to be passed to the makefile or the compilation will fail (makefile).
- VGM player
  . Added 40 new entries. Fixed a good number of entries for correct shortnames, increased description info and filled in "no_data" fields (hash\vgmplay.xml).
  . Added proper dates to nearly all ?? YEAR fields. Fixed dozens of short names to better match MAME's softlist metadata. Enhanced some descriptions for many Sega titles - properly denoting the actual console when possible (hash/vgmplay.xml).
- Compiling
  . Use swapendian_int16/int32 (i860\i860dec.hxx, machine\dp8390.cpp, machine\gayle.cpp)
  . Fixed redundancy in pacman-key --verify call. Appveyor VS2017 image only ships with pacman 5.1.3 as of now. In that version pacman-key --verify only takes one argument, the signature (appveyor.yml).
  . Added simple .editorconfig. Clean up command-line -h output, tidy up emulator_info class a little and added trim trailing whitespace to .editorconfig.
  . Documentation update for vector options (docs\source\commandline\commandline-all.rst). Fixed compilation of docs for HTML and manfiles.
  . Fixed non-x86 build and try to make sure it does not break silently again. Do not build x64 DRC backend when C backend is forced. New CI target (mametiny + kinst). Switch travis to CI target and appveyor to CI target.
  . Define IMGUI_DISABLE_OBSOLETE_FUNCTIONS consistently: 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 (scripts\src\3rdparty.lua).
  . Clean up Clang options now that Clang 5 is a hard requirement and suppress xor-used-as-pow warning introduced in Clang 10.
  . Cleanup mame\arcade.flt and mess.flt
  . Enable ppc64le for travis: Added akkaarrh to the ci target. Switched Travis CI to Ubuntu Focal. Allow ppc64le CI build to fail. Report CI status as soon as a job has failed or remaining jobs are allowed to fail.
  . CHDMAN: GCC 9.3 is actually the cutoff point for legacy MSVC-style long format flags
  . Make cleansrc target use shell type to select correct syntax rather than assuming Windows uses cmd shell (makefile).
- Debugger
  . Added 'fill' command to debugger. Syntax and operation are similar to 'find' command (debug\debugcmd.cpp).
  . Documented rowsize parameter for dump command in debugger help.
  . #if DEBUG_VRAM_VIEWER instead #ifdef (video\epic12.cpp)
