- CPU
  . Analog Devices ADSP21062 'SHARC': Fixed DRC crashes in DEVNOCLEAR debug builds
  . 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. Changed default interrupt vector.
  . 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.
  . Hyperstone: Fixed DRC crashes in DEVNOCLEAR debug builds (e132xs\e132xs.cpp)
  . 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.
    . Fixed old regression with NEG opcode flags. Fixes mysterious deaths in Krull cave scene (ID 06896).
  . 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. Log unimplemented IACs (i960\i960.cpp).
  . KONAMI CPU: Fixed broken ROLD/RORD opcodes (m6809\konami.ops)
  . MCS-51: Added Dallas DS80C320 HSM, Siemens SAB80C535 and Intel 8344AH RUPI-44 disassemblers (cpu\mcs51\mcs51.cpp)
  . Microchip PIC16/17: Added disassembler for PIC17 family and preliminary PIC17C4X emulation. Added a PIC16C70 disassembler.
  . Mitsubishi M37710S4: Rename some registers to agree with Mitsubishi documentation. NOP unused SFR area. Actually SFR area 2-9 is external on some chips.
  . Motorola Atari Jaguar GPU 'Tom': Added notes of debugging feature. GPU code can be executed out of external RAM. Reference: Midsummer Technical Reference Manual.
  . 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).
  . Motorola MC68HC05Cx: Simplified handler signatures. Added MC68HC705C4A type (m6805\m68hc05.cpp).
  . 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.
  . Sony PSX CPU: Switched PlayStation CPU over to memory_access_specific
  . Texas Instruments TMS9995: Fixed different behaviour of the (MESS) tutor.cpp driver in the DEVNOCLEAR branch
  . Texas Instruments TMS32031: Added/Correct notes for internal peripherals and chip family differences. Fixed chip name (no NMOS variant exists) and some descriptions. Fixed Microcomputer mode when 320C30 internal ROM is empty. Reference: TMS320C3x User's Manual.
  . Toshiba TMP95C06x: Splitted derived types into separate files. No need for separate 8-bit and 16-bit maps now. Break up the register blocks (cpu\tlcs900\tlcs900.cpp).
- SOUND
  . Atari C012294 POKEY: Removed #include "machine\rescap.h" (sound\pokey.h, audio\jedi.cpp, drivers\asteroid.cpp, ccastles.cpp, centiped.cpp, cloak.cpp, liberatr.cpp, maxaflex.cpp, mhavoc.cpp, missile.cpp, tempest.cpp and tunhunt.cpp)
  . Atari CAGE: Fixed [debug] assertion in 'San Francisco Rush' and 'San Francisco Rush: The Rock' (audio\cage.cpp) (ID 07668)
  . ICS2115 WaveFront Synthesizer
    . Added imperfect_features related to incorrect/unverified interrupt, interpolation and ramping Interpolation issue is most noticeable in Cave PGM hardware game music (sound\ics2115.h).
    . Use device_memory_interface for fetch external samples and for later DMA and DRAM interface support. Allow ulaw interpolation (some instrument sound samples in IGS PGM Motherboard sound ROM is u-law). Added notes. Reduced duplications.
  . 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.
  . Namco 54XX: Increase the length of the Namco 54XX IRQ to fix Bosconian shot sound regression
  . OKI ADPCM: Added looped sample support. Allow reading current output without decoding. Fixed initial values and descriptions (sound\okiadpcm.cpp)
  . QS1000: Added save state related to loop support (disabled currently)
  . N2A03 APU: Correct noise algorithm
  . Ricoh RF5C164: Verified default register map (datasheet). Implemented some chip variant differences. Implemented RF5C164 default register map (Reference: RF5C68 Datasheet and Mega CD hardware manual PCM sound source). Use STRUCT_MEMBER for state saving.
  . Ricoh RF5C400: Fixed wrong bus width (sound\rf5c400.h)
  . SSi TSI S14001A: Zero-fill variables, fixes missing speech in some (MESS) Fidel chess drivers in DEVNOCLEAR builds.
  . Williams CVSD Sound Board and Williams NARC Sound Board: Fixed the Williams audio HC-55516 digit write to mask the digital input bit correctly (instead of sending a whole byte) and fixed the clock set and clear logic to accurately reflect schematics (audio\williams.cpp).
  . Williams WPC Sound: Fixed wpcsnd memory map to explicitly define mirrors and fixed two swapped write handlers in the map (audio\wpcsnd.cpp)
- 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.
  . 8042 Keyboard/Mouse Controller: Initilized variable that caused problems for the PCI PC drivers in DEVNOCLEAR builds (machine\8042kbdc.cpp)
  . Atari Slapstic: Transfer legacy slapstic handling routines from machine\atarigen.cpp to device. Eliminated address_space argument from legacy read/write handlers (machine\slapstic.cpp).
  . 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)). Simplified pfunction state handling. Removed dependency on pstate.h.
    . 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 (machine\nl_breakout.cpp)
    . 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.
    . Added working 74125 and 74126 implementations. These tristate buffers natively support tristate outputs. For use cases with fixed enable inputs the devices support a parameter FORCE_TRISTATE_LOGIC which if being set to 1 makes the device behave like a logic output. Added additional syntax and consistency checks for tristate outputs. Updated the example and added dip implementations including documentation.
    . Improved typesafety for source locations. During object creation netlist tracks the source files which provide object creation. This is later used e.g. by nltool to create documentation from source.
    . Added missing TTL_74125 definition (netlist\macro\nlm_ttl74xx.h). Added 7421 device.
    . Improved timing accuracy for sound devices. Better alignment between netlist_time and attotime.
    . Simplified factory call structure. This change will make it a lot easier to add enhanced functionality to the factory infrastructure. Using integral constants also improves linking stability. Improved syntax of generic device descriptors.
    . Added tristate support for rom devices. Rom and prom devices now properly support tristate outputs. Native OC output still on the todo list. In addition this commit fixes a number of bugs around dealing with macro level parameters and improves documentation by adding a parameter table. Also srcclean.
    . Consolidate 9316-type counters. This needs more attention since for certain compilers there is a considerable performance degregation. It looks like this is only triggered if too many variants are declared in one cpp file and the compiler stops inlining.
    . Fixed performance issues and VC2019. For reasons unknown to me compile optimizations do not behave for template code. If the implementation is in separate compile units, the code compiles and performs.
    . Better integretation of INT128. Moved penum into own header file (netlist\plib\penum.h).
    . Pong (Rev E) [TTL] now peaks at 589% compared to 570% before. Amongst a number of improvements in nl_base.h and the 7493 was touched. Also has some code cleanup and hopefully faster compilation due to extern template declarations.
    . Moved configuration entries into netlist namespace and netlist parsing where it belongs. Memory system cleanup.
    . Fixed NVCC compile for 10.2. plists.h was splitted into plists.h, pmulti_threading.h and ptimed_queue.h. In addition removed plists.h from a number of files it wasn't used in. Certain minor adjustment needed to be made for CUDA toolkit 10.1 and 10.2.
    . Refactored ppmf.h. Make more use of C++. Prepare coexistence of different delegate types. Untangle code. Reduced macro usage. Changed use of NETLIB_DELEGATE macro. The macro now has only one parameter, the local name of the delegate. Use callbacks to access terminals (debugger). Device factory enhancements. Factory elements can now pass additional parameters to device constructors. This makes the design of interface objects like analog callbacks easier. The change also allowed to remove some "deep" calls into the core from the MAME interface in netlist.h. Drop C++11 support. This wasn't working since the last factory changes. Removed it. Basically replace C14CONSTEXPR with constexpr. Moved multiparameter streaming into nl_interface.h. Clang-tidy, header order fixes.
    . Enabled UTF7 filenames on windows. Fixed visibility of classes in nlid_system.h and tidy warning for penum. Reduced macro usage and make use of pstring UTF8. Fixed win float exceptions.
    . More C++14, use enable_if_t instead of enable_if. Cleaned up the use of memory allocation arenas. Reduced MACRO usage, use std::conditional where possible. ppmf simplification. Arena code maintenance. Fixed MSVC build. MSVC has an issue with SFINAE and overloading resolution. A discussion can be found here:  https://stackoverflow.com/questions/31062892/overloading-on-static-in-conjunction-with-sfinae. The previous code compiled with GCC and Clang on all platforms and compilers apart from MSVC. Replaced with double template specialization. Allow selection of base arena for pmempool_arena. Further optimize ppmf.h: Moved towards a pure c++ constexpr solution to derive the optimal pointer to member function solution. All the macro madness is centralized to a compile_info struct with static members. For the time being the evaluation result is compared against the previous approach. Going forward this will be dropped as well as the support for MINGW with GCC <= 4.6. Prepare path to non-virtual update functions.
    . Fixed win32 compile and all targets without INT128 support
    . Improved static solver performance by 5%. Use a more condensed matrix format for go, gt and Id matrices. In addition, optimize the static compilation code. Make fostrm actually write to file.
    . Performance improvement and refactoring: Kid Niki now achieves up to 910% when run with static solvers and with nltool. That is significant better than the 860% we have seen previously. This increase is driven by using a global memory pool in the solver code. In addition the following refactoring and code maintenance work is included. Please excuse the large commit, some of this took interfered with other work and the detail development steps were ugly. GSL support: This commit adds pgsl.h which implements a very limited number of the functionality of the gsl header described in the C++ core guidelines. Clang-tidy fixes. A significant refactoring of palloc.h. Aligned hints were removed, they added complexity without a significant performance gain. Vector operations should better be done on special spans/views. The code has been tested on linux with G++-7, G++-9, Clang-11. On Windows MinGW-10, VS2019 and OSX Clang-11.
    . Fixed for some compilers not being CWG 1579 compliant (netlist\nl_setup.cpp). Fixed copy elusion bug on OSX and Clang < 8. Solution discussed with AJR in chat (machine\netlist.cpp and nl_setup.cpp). Fixed nltool build on CWG 1579-noncompliant compilers.
  . Floppy
    . Improved HLD behavior, always activating output at start of type II & III commands. Use attotime::to_string instead of custom time-to-string method and fixed command logging messages (machine\wd_fdc.cpp).
    . Improved HLD/HLT handling, fixed FD1771 timings and enable spinup_on_interrupt. Do not delay SEEK with no Verify flag. Improved write protection. set BUSY during initial restore to make it correctly interruptable (machine\wd_fdc.cpp).
    . Accept new commands while in busy state, workaround for spurious recursive calls if HLD used for drive motor control, don't change track and data registers during reset (machine\wd_fdc.cpp).
  . 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.
  . 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 8155 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.
  . Intel 8279 KDC: Keyscan overhaul: Improved handling of multiple key depressions. Emulated debounce cycles (emulation partly disabled due to MAME updating inputs only once per frame). Added switch closed status flag for sensor matrix mode.
  . K037122 2D Tilemap: Updated K037122 hardware information. Added screen raw parameters (verified in both 3DFX Voodoo and K037122 display timing parameters).
  . K052109 Tilemap Generator: Correct video clocks (drivers\simpsons.cpp and video\k052109.cpp)
  . K056230 LANC: Misc demacroization. Documentation updates.
  . Keyboard
    . Fixed typos in PORT_CHAR definitions (machine\keyboard.cpp)
    . Fixed for UI Paste with the Default Serial Terminal (emu\natkeyboard.cpp). Without this fix, 8 characters @^&()\:" cannot be pasted from the UI.
  . Konami PowerPC Common Functions: Removed 7seg LED hack (machine\konppc.cpp)
  . MC6850 ACIA: DRE should read clear in reset and set coming out of reset. Fixes a lockup running UniFlex on the SWTPC09. Tested on hardware, the TDRE flag reads as zero in the reset state and reads as set when taken out of reset, and even if data has been written to the data register while in the reset state.
  . Motorola MC6845 CRTC: Max visible lines might not be what really is displayed, see (MESS) IBM PC 5150t demo 8088mph.
  . 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.
  . Namco 50xx/51xx/52xx/53xx/54xx/05xx: set_input_line is synced, don't need extra synchronize.
  . NVRAM: Don't save 0byte file (machine\nvram.h, emu\dinvram.h, machine\rp5c01.h and emu\machine.cpp)
  . PSX GPU: Initialized a couple of variables that were causing problems in DEVNOCLEAR debug builds
  . Signetics SCN2674 AVDC: Delayed commands use display pointer address, not screen 2 address.
  . Voltage Regulator: Fixed problem with DAC stream slice update (sound\volt_reg.cpp)
  . Z80 SCC Channel: Don't invent data (m_rx_fifo_rp_step). Clear IUS not IP.
- 40love.cpp: Use MB14241 device
- 8080bw.cpp: Periodic timer can't be adjusted (audio\8080bw.cpp)
- aleck64.cpp: Initialized variable that caused problems in DEVNOCLEAR debug builds (machine\n64.cpp)
- atarifb.cpp: Improved interrupts, LED multiplexing and sprite raster effects (ID 01731).
- 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.
  . Fixed Road Blasters steering wheel does not auto center. The RoadBlasters steering wheel is very much like the Star Wars yoke, without the vertical (Y) axis (ID 07671)
- cdi.cpp
  . Various CD-I changes: Started hooking up the Quizard MCU. Renamed CDI_SLAVE to CDI_SLAVE_HLE in prep for an LLE device. Added more comprehensive notes to the driver. Removed NO_DUMP cdic.bin as the CDIC is apparently not an MCU. Copied SERVO and SLAVE MCUs into cdimono1 set from cdi910 set and marked with BAD_DUMP. Replaced protection HLE with proper MCU hookup. Philips SCC68070: Improved UART Tx/Rx behavior, though it still functions in parallel rather than serial.
  . Initial changes to get Quizard 3 and Quizard 4 Rainbow working. More CDIC fixes, (MESS) Hotel Mario now has correct audio (machine\cdicdic.cpp).
- chihiro.cpp
  . More precise implementation of rcc and rcp vertex shader instructions. Moved poly_manager dependency to new nv2a_rasterizer class (video\xbox_nv2a.cpp). Fixed "xbox vprogdis" debug command (machine\xbox.cpp). Added placeholder for methods 1e80-1e90 (video\xbox_nv2a.cpp).
  . Added debugger command "xbox vdeclaration", used to decode the vertex shader declaration stored at a certain address (machine\xbox.cpp). Some refactoring before modifying vertex data reading (video\xbox_nv2a.cpp).
  . Big update to chihiro/xbox 3D graphics: Vertex shader and pixel shader refactoring. Register combiners support multithreading. Corrected reading of vertex attributes. Perspective correct vertex attribute interpolation and texture mapping. Basic support for texture address modes. Secondary color and fog color available as inputs to pixel shader. Interpolate all 4 possible texture coordinates. Corrected order of vertices when drawing quad list primitives.

- 280-ZZZAP and Laguna Racer: Updated 280zzzap audio API in preparation for netlist audio. This is only API changes, following the pattern used by cuavas within the past year to update other games in mw8080bw. New netlist-based audio implementation for 280-ZZZAP (audio\nl_280zzzap.cpp), derived from Midway game logic board schematic. The sound generally matches that heard in videos of the machine, though the real machine seems to have more bass and less treble. This may be a cabinet effect or something else, such as a difference in component values. Due to the number of complex components being emulated and the nature of the circuits, this netlist adds a lot of overhead, but it's still fast enough to run at greater than real speed on modern hardware. With minor changes, this implementation should also support 'Laguna Racer'; with somewhat more substantial changes, it would also support 'Super Speed Race'. Both of these games use sound circuits based on those for 280-ZZZAP.

Note: Is the screen horizontal resolution maybe 285? PCB videos do show a slightly larger right border though. Bullet vs tilemap offsets are correct when compared with PCB videos (both playfield area, and radar area). Bullet vs sprite offsets are also correct. The radar area is offset by 3 pixels, also confirmed with PCB video when it does the VRAM check.

- MAME
  . VIDEO RENDERING SYSTEM
    . Fixed prescale option does not work properly on D3D renderer (ID 07536). Removed old StretchRect code. All drivers these days punt it to a shader backend anyway, and it's causing issues with -prescale (render\d3d\d3dcomm.h and drawd3d.cpp).
    . Don't do frameskip related calculations at init time (emu\video.cpp). Frameskip setting is now upper frameskip limit when autoframeskip setting was enabled (emu\emuopts.cpp and video.cpp). Show frameskip max value in speed_text (emu\video.cpp).
    . BGFX: Corrected a data overrun in the D3D12 backend from allocating only enough texture data for width*height, not rowpixels*height. Don't try to invoke a frame immediately after resetting the renderer during tear-down. Fixes crash on exit with the D3D12 backend. Corrected hlsl.json to apply the intended screen tint (bgfx\chains\hlsl.json).
  . MEMORY SYSTEM
    . Slight emu\emumem.cpp speedup. Implemented on the 680x0 for now. memory_access_specific is declared and used exactly like memory_access_cache, but does not cache. It does, however, shortcut the virtual call into address_space, so that's one layer of call less. Gives another nice speedup for accesses with bad locality (e.g. anything that's not opcodes), at the expense of having a specifically typed object in the class. Should do well for cpus in general, drivers can keep using the address_space access calls for easier logistics. Masking before dispatch at top level is not needed because it's already done at the global mask level.
    . Mask address where absolutely necessary (emu\emumem.cpp). This change fixes the edge case of an unaligned accesses to the top of the space not wrapping around, which was causing at least one driver (Alpine Surfer) to crash.
    . Cache and specific change syntax, and are not pointers anymore (emu\emumem.*): Added a template parameter to everything (theoretically the address space width, in practice a level derived from it to keep as much compatibility between widths as possible) so that the shift size becomes a constant. Changed the syntax of declaring and initializing the caches and specifics so that they're embedded in the owner device. Solves lifetime issues and also removes one indirection (looking up the base dispatch pointer through the cache/specific pointer). Protect against savage memsets (emu\emumem.h).
    . Fixed bad destruction order by not removing the notifier on cache destruction, they're supposed to be long-lived anyway (emu\emumem.h).
  . DEVICE
    . Initialized a couple of variables, fixes numerous bugs in DEVNOCLEAR debug build with BIOS roms in devices (emu\device.cpp).
    . Removed the space for the handlers, it is not needed anymore (emu\devcb.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).
  . UI
    . Skip -romident matching process and display error message when no files are found (mame\clifront.cpp)
    . Only warn about external artwork when it wasn't loaded (ui\info.cpp and emu\render.cpp)
  . LUA engine
    . Consolidated code for pasing enum strings. Added rom_entry library (mame\luaengine.cpp).
    . Setting analog inputs don't work in LUA (emu\ioport.cpp). Fixed set_value for analog inputs. Expose ioport_setting to luaengine.
  . Programmable Logic Device (PLD)
    . Added GAL20V8 support to the jedutil tool
    . jedutil updates: 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 ythe 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. Initial work on supporting the GAL20V8 device. Adding an initial regression test for the GAL20V8. Tweaked the function to print text to handle the end of line character. Fixed some mis-configurations of the GAL20V8 device. Added regression tests for the GAL20V8 device. Fixed the output of the GAL20V8 when viewing a jed in simple mode to properly display outputs as also being inputs for certain pins. Fixed the output of a GAL16V8 device in Simple Mode to mark relevant output pins as providing feedback as documented in the datasheet. Corrected the output feedback state when in simple mode for the GAL16V8 and GAL20V8 devices.
  . 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
  . First attempt at auto-sort of mame.lst
  . First completed pass of commandline parameters. Get the audio latency numbers right and add PortAudio info. FreeSync/GSync information cleanup. Added tip for keyboardprovider (commandline\commandline-all.rst and usingmame\commonissues.rst).
  . Fixed frame sync regression (emu\machine.cpp, recording.cpp and util\png.cpp). Fixes recorded MNG and WAV files are out of sync (ID 07673).
- MAC OS X: Fixed OS X build with Xcode 7 (scripts\src\3rdparty.lua). Fixed OS X build on older Xcode versions.
- CHDMAN: Support characters outside ASCII in command line arguments. I64 size qualifier is only needed for MSYS64 GCC 9 and earlier (tools\chdman.cpp).
- VGM player: Implemented some features from QuattroPlay by superctr
- 3rdparty: New AsmJit library (https://asmjit.com). Added AsmJit to COPYING.
- Compiling
  . Fixed GCC 10 uninitialized (modules\vzdos.cpp) struct warning and GCC 10 fix for sqlite3 (scripts\genie.lua)
  . Enable option to generate symbols in Release as well as Debug under Visual Studio (this is important because debugging Debug builds is too slow) (scripts\genie.lua)
  . Fixed scripts\target\mame\dummy.lua
  . Updated Travis CI build environments (travis.yml). Switched Ubuntu build from GCC-9 to GCC-10 and MacOS build from Xcode 11.0 (MacOS 10.14.6) to Xcode 11.5 (MacOS 10.15.4).
- 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)
  . Debugger expression and memory access overhaul: Memory references in expressions no longer default to the console's visible CPU if no device name was specified, except when entered through the console itself. Expressions in view windows now use the context of the currently selected device instead. The pcatmem debug command and similar qt mouseover function now produce an error message if the initial address translation fails. Related internal changes: The debugger_cpu class no longer interprets memory accesses. The existing routines have been moved into symbol_table (which used to invoke them as callbacks), and reimplemented in most other places. Thecode duplication is a bit messy, but could be potentially improved in the future with new utility classes. The cheat engine no longer needs to hook into the debugger_cpu class or instantiate a dummy instance of it. The inclusion of debug/express.h within emu.h has been undone. Some debugging structures now need unique_ptr to wrap the resulting incomplete classes; hopefully the performance impact of this is negligible. Another direct consequence is that the breakpoint, watchpoint and registerpoint classes are no longer inside device_debug and have their own source file. The breakpoint list is now a std::multimap, using the addresses as keys to hopefully expedite lookup. The visible CPU pointer has been removed from the debugger_cpu class, being now considered a property of the console instead. Many minor bits of code have been simplified. Fixed crash when attempting to write to memory from debugger (debug\express.cpp).
  . Added '-debuglog' option to log debug console output to file. When this option is specified, all console output is echoed to a log file. Some caveats/limitations: The file-open process was copied from -log, so it has the same limits. Filename is hard-coded (debug.log). File is overwritten if it exists. File is opened during emulation initialization. Thus, the file is cleared if you invoke the "Hard Reset" debugger command. Probably some other details I don't know about. Logging works as such: When a string is appended to the scrollback buffer, it is also written to the log file. Some commands forcibly wrap their output (e.g. 'help' to 80 columns). Because this wrapping is done inside the scrollback buffer, the text written to the file is not wrapped. This can be seen with 'help execution'. Eliminated space.device() in watchpoint code (debug\points.cpp).
  . Added 'condump' command to export console buffer to a log file. This is another debugger enhancement - it allows you to export the current contents of the debug console window to a file. The filename parsing is based on the 'trace' command, and as such, supports both the "{game}" placeholder, and the ">>" prefix for appending instead of overwriting.
  . Allow debugger dump command to dump with byte granularity from address spaces with positive shifts.



"Theory is when you know everthing but nothing works. Practice is when everything works but no one knows why.
In our lab, theory and practice are combined: nothing works and no one knows why."

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 polarity of 74LS125 tristate input.
  . 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).
  . K051649 SCC1: Fixed frequency behavior. Modernized save state. Correct type values
  . 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).
- aleck64.cpp: Modified burn_cycles method (machine\n64.cpp)
- 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.

- 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)
- 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.
  . Corrected Pokerino (L-1) sound PROM. Fixed loss of sound in Still Crazy (ID 07689).
  . 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.
  . Fixed Visual PinMAME build. Changed return value to same type as expected (s3.cpp, s4.cpp, s6.cpp, s6a.cpp, s7.cpp, s8.cpp, s8a.cpp, s9.cpp and s11.cpp)
- Sadari: Added button 3 (ID 07693)
- Super Othello: Fixed ASR8 and ASR16 opcodes (cpu\m6809\base6x09.ops). Simplified maincpu-subcpu comms, game works again since the M6809 rewrite in MAME 0.148u2 (ID 06033).
- Fixed rom names in cave.cpp, ddragon.cpp, exidyttl.cpp, m72.cpp, namcos2.cpp, s3.cpp and sidepckt.cpp

    . 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)
  . DEVICE
    . Removed m_totalcycles workaround (emu\diexec.h)
  . Get help from website instead of files that don't exist (mame\clifront.cpp)
  . Enabled save state support in big10.cpp, kas89.cpp, kurukuru.cpp, luckybal.cpp, namcos2.cpp and tonton.cpp. Fixed save state support in luckybal.cpp and rulechan.cpp.
  . Fixed initializations issues that were causing problems in DEVNOCLEAR debug builds (machine\6850acia.cpp, ncr539x.cpp, video\dp8350.cpp, k057714.cpp and jangou_blitter.cpp)
- Compiling
  . MinGW SDL build fails with end-group auto added by that LinkSupportCircularDependencies flag option (scripts\genie.lua)
  . asmjit
    . Only build asmjit on x86 and x86_64 (scripts\src\3rdparty.lua and main.lua)
    . Implemented asmjit emitter. Consolidated many helpers. Corrected previously reported bugs (cpu\drcbex64.cpp).
  . Added arm64 and s390x to Travis CI (travis.yml)
