- CPU
  . Intel I386
    . Added new MAME debugger function cacheflush(x) to writeback cache: cacheflush() or cacheflush(0) writes back dirty cachelines to ram, cacheflush(1) also marks dirty cachelines as clean and cacheflush(2) or cacheflush(3) also invalidates the whole cache.
    . Athlon XP updates to memory access: Now Athlon XP supports WrMem and RdMem bits in fixed range MTRRs. Accesses to the first megabyte can be directed to system memory (ram) or memory-mapped-io (mmio) (the pci bus). Above 1mb accesses below the top_mem MSR address ram the others mmio. At reset everyting is directed to mmio. Addresss spaces work in the following way. AS_PROGRAM is used for ram. AS_DATA is used for mmio. AS_OPCODES is used by the debugger disassembler and in memory views to look at the memory contents from the point of view of the microprocessor, including the cache. Also some class members have been added to the save state.
  . MC68307: Use internal map for interrupt acknowledgment (was overlooked). Disabled side effects for interrupt acknowledgment.
  . MIPS-III
    . Added divide by zero floating point exception
    . Clean up LL/SC instructions and add debug break to DRC
    . Always set BadVaddr on TLB miss. The TLB handler needs this to fill in the table (mips\mips3drc.cpp).
    . Don't adjust EPC to pc-4 when not backing up (mips\mips3.cpp)
  . Motorola MC6809
    . battlane.cpp: Speculative 6809 de-legacying
    . bfm_sc2.cpp: Verified 6809 types (driver and video\bfm_dm01.cpp)
    . lemmings.cpp: De-legacy the MC6809, which will run slower (more within parameters) as a result. XTAL and CPU type verification.
    . mpu4dealem.cpp: Changed legacy type of "existing 6809 CPU" to be the same as base MPU4
  . Motorola MC68000
    . Rework 68000 interrupt handling: Implemented the cpu space as an address space. Make all vectored interrupts use the cpu space. Make it possible to direct the cpu space to another space, use it for amiga (which handles it as a normal AS_PROGRAM read). Make it possible to disable the priority muxer and get 3 lines instead, use it for CPS2.
    . Fixed build (this instruction will need further fixing) (m68000\m68k_in.cpp)
    . Fixed vector fetch width and autovector mapping (m68000\m68kcpu.cpp)
    . Use 8-bit handlers for 68000 vector fetches
    . Make the autovector abstraction a bit less leaky (m68000\m68000.h and m68kcpu.cpp)
  . Motorola MC68705
    . Added other Motorola M6805 Family HMOS variants
    . Use NVI for internal map to prevent segmentation fault

    . Combined DBIN/IAQ operation with setaddress, no need for separate callbacks.
    . Checked min/max cycles
    . Changed setaddress method signature to (address, buslines); treating an address as a value to be written does not work with memory maps.
  . Texas Instruments TMS9900: Modernized logging, fixed LDCR/STCR handling of reg indirect/auto-inc mode (*Rx+).
  . Texas Instruments TMS9980A: Don't completely block reads from debugger
  . Toshiba TMP68301: Disabled side effects for interrupt acknowledgment
  . Z8 / Zilog Z8681: Added register pairs to debug state
  . Z80 CTC: Prevent integer overflow in Z80 CTC device, which causes a runtime error on WebAssembly builds. The issue was introduced in MAME 0.204 (fixed-rate clock input to be configured...)
- SOUND
  . Hudson Soft HuC6280 PSG: Fixed LFO enable bit. Implemented LFO reset bit behavior. Correct frequency behavior. Added notes (sound\c6280.cpp).
  . K053260 KDSC: Simplified handlers. Use std::s. Shorter type values. Fixed spacings.
  . K054321 Maincpu-Soundcpu interface: Fixed synchronizing maincpu-soundcpu communication issue. Use gen_latch.
  . QS1000: Added imperfect_features related to emulation incorrection
  . Ricoh N2A03: Added device_mixer_interface instead hardcoded tags
  . Taito Ensoniq Sound System: Use CPU space for interrupt vectoring (audio\taito_en.cpp)
  . Yamaha AICA

  . DECO BAC06 Tilemap: Make bpp masking related to gfx. Make tilemap draw routine related to cliprect. Cleanup unnecessary address_space in handlers. Fixed spacing.
  . Discrete Netlist
    . Added MOSFET model. Currently capacitances are not modelled. This is a 3-pin model (bulk connected to Source) with provisions to extend it to 4-pin at a later stage.
    . Added a capacitor generic model which is charge conserving. Switch netlist to use this model instead of constant capacity model.
    . Start putting constants into a central place. Note: Please expect minor timing differences due to a different numerical path. The cmos inverter example illustrates the analog implementation of a cmos inverter gate. These were used a lot back in the 70s/80s to generate sinus waves. The model should also be able to better emulate 4066 analog switches. The addition of a relatively simple capacitor model is planned at a later stage. Expect everything from the MOSFET model at the current stage. Wrong results as well as convergence issues and crashes.
    . Improved MOS transistor model. This is a significant improvement to the MOS transistor model. It added modelling of the Meyer capacitance model. This is a somewhat academic addition since the effects occur on a nanosecond time scale and have a huge impact on performance. I plan to make the capacitance model selectable. Both on a model level as well as by introducing a global solver parameter. The model delivers comparable results to LTSpice.
    . Timing bug fix. Affects regression tests. This fixes a rounding issue in the ptime code. This bug surfaced when I tested netlist with picosecond resolution in ptime. This will have a small impact on every driver using netlist. Forbreakout, it required to adjust the color overlay.
    . Added global parameter to disable semi-conductor capacitance modelling. Added global NETLIST.DEFAULT_MOS_CAPMODEL parameter. Setting this to zero disables using capitance modelling in mos models. On a per mos device basis this can be achieved by adding CAPMODEL=0 to the model definition, e.g. MOSFET(X, "NMOS(CAPMODEL=0)"). Improved MOSFET convergence by using log-stepping.
    . Refactored model code. Move generic models into nld_generic_models.
    . Added nld_generic_models.h to netlist.lua
    . TYPE=2 opamp model and MB3614 fixes: Untie diode code. Fixed some typos. Added TYPE=2 opamp model which omits output voltage limitation. Useful for determining causes of non-convergence. Fixed MB3614 opamp parameters to match datasheet
    . MB3614 function controlled VARCLOCK and other improvements: Fixed MB3614 parameter. Added VARCLOCK which derives step size from function. Optimized function handling in CS and VS. Fixed a bug in ppreprocessor. Added trunc to pfunction. Added opamp_amplification_curve to derive characteristic amplification curve.
    . Added LM2902
    . LM3900
      . Align LM3900 pin names with other opamps. Added a better voltage clamping model. Added high precision model (disabled due to performance). Adjusted LM3900 model, fixed clipping in Zaccaria. Added frontiers to netlist audio and fixed AY8910 interfacing. The setup needs AY8910_RESISTOR_OUTPUT. Frontiers boosted performance. Route speech and DAC through netlist filtering. Also hook up all potentiometers so they can be adjusted from within the MAME UI (audio\nl_zac1b11142.cpp and zaccaria.cpp).
      . Improved and fast LM3900 model: LM3900 model 3 only has half the number of BJTs compared to model 1. But delivers comparable results for Money Money. Model 3 follows the datasheet. I left code for Model 0 and 2 in for educational reasons. Fixed Mario Bros LM3900 regression (audio\nl_mario.cpp).
    . Added more SPICE elements to the conversion code
    . Added frontiers to netlist audio and fixed AY8910 interfacing. The setup needs AY8910_RESISTOR_OUTPUT. Frontiers boosted performance (audio\nl_zac1b11142.cpp and zaccaria.cpp).
    . Clang lint fixes and pedantic warning fixes. Bug fixing: Fixed sound route dependency. Added "K" as a valid Kilo multiplier. Fixed current source parameter update.
    . Modernized interface
    . Added palestra, testpat and cocoloco to mamenl subtarget (scripts\target\mame\nl.lua and mame\nl.lst). Added skeleton drivers to mamenl build (a1supply.cpp, aleisttl.cpp, bailey.cpp, chicago.cpp, electra.cpp, exidyttl.cpp, fungames.cpp, meadwttl.cpp, monacogp.cpp, pse.cpp, ramtek.cpp, segattl.cpp, taitottl.cpp and usbilliards.cpp).
    . Improved netlist initialization in drivers.
    . Added validation support to netlist device. mame -validate now also checks all netlist devices. It does this by constructing a temporary netlist. This commit also fixes some memory leaks and a bad bug which surfaced in validation.
    . Improved validation code. Adjusted warning levels and fixed a number of topics identified.
  . Floppy
    . Eliminated floppy_get_count (imagedev\flopdrv.cpp)
    . Implemented threshold to accept disk images with a few excess and empty tracks at the end used by HFE and DSK loaders for now (formats\dsk_dsk.cpp, flopimg.h and hxchfe_dsk.cpp).
    . Drive selection improvements: Deselect drives upon reset, or select drive 0 for older FDCs with multiplexed select lines. Deselect other floppies when using set_floppy (machine\upd765.cpp).
  . Harddisk: Added ability to throttle HDD DMA transfer speed. Fixes strange freeze in attract mode of San Francisco Rush 2049 (ID 07242).
  . Intel 8259 PIC: Avoid reacting to debugger reads
  . InterLan NP600A-3 Intelligent Protocol Processor: Preliminary 82586 hookup. Added 82586 interrupt.
  . Kaneko KC002 Sprites and Kaneko VU002 Sprites: Simplified handlers, fixed namings and use shorter type vales (video\kaneko_spr.cpp).
  . Kaneko VIEW2 Tilemaps: Added address_map for VRAM handling. Moved expro02.cpp exclusive tilemap bankswitching function into expro02.cpp (now callback'd). Fixed namings. Reduced duplicates. Simplified handlers.
  . Keyboard: Connected matrix and ports (bus\pc_kbd\pcat101.cpp). After this change, the keyboard sends scan codes to the host successfully, but fails to receive/process commands from the host. Failure is probably due to differences between the 6805U3 that's really in the keyboard, and the 68705U3 that's the best match in mame at the moment, so requires expanded 6805 emulation.
  . MC68681 DUART: Disabled side effects for interrupt acknowledgment

- Renamed (dd_l2) to (dd_lu1) and (ltcasinn) to (ltcasin2a)
- MAME
  . VIDEO RENDERING SYSTEM: Added xBGRBBBBGGGGRRRR case of palette format (emu\emupal.cpp)
  . DEVICE
    . Simplified read/write handlers (audio\decobsmt.cpp, geebee.cpp, warpwarp.cpp, taitosnd.cpp, drivers\expro02.cpp, itech32.cpp, ninjaw.cpp, othunder.cpp, slapshot.cpp, taito_z.cpp, warriorb.cpp, williams.cpp, wmg.cpp, emu\emupal.cpp, ins8250.cpp, watchdog.cpp, z80ctc.cpp, z80dart.cpp, z80pio.cpp, z80sio.cpp, video\decbac06.cpp, deco16ic.cpp and tc0360pri.cpp)
    . Removed unnecessary arguments in handlers (machine\gen_latch.cpp and sound\tms5220.cpp)
    . Misc MACHINE_CONFIG removal
  . MEMORY SYSTEM: Removed obsolete alignement limit (emu\emumem.cpp). Correct start/end on big endian (emu\emumem_mud.cpp).
  . Offset is now optional and defaults to 0 (emu\softlist.cpp)
  . Annotated set_input_line_vector (Example cvs.cpp: m_audiocpu->set_input_line_vector(0, 0x03); // S2650)
  . Multi-Language: Updated Brazilian Portuguese and Greek translation
- Linux: Linux X11 Input: Fixed multiple lightgun support on X11 Linux, every lightgun event was passed onto every lightgun device within MAME. This obviously works for 1 gun, but with 2, it causes both crosshairs to move in the same direction at the same time (input\input_x11.cpp).
- MAC OS X
  . Updated OS X debugger window titles when restoring configuration for disassembly and memory viewers (osx\disassemblyviewer.mm and memoryviewer.mm)
  . Fixed compiling with Xcode 10.2 on MAC OS. This shouldn't affect any other Clang configurations (or any older Xcodes); LMK if problems occur (3rdparty\asio\include\asio\detail\config.hpp).
- VGM player: Volume Multipler support
- Compiling
  . Fixed compile (bgfx\shaders\chains\xbr\fs_xbr-lv3-noblend.sc). Note: We do not seem to have shader compilation in our automated testing, that could be a problem.
  . Fixed non-Apple Clang (3rdparty\asio\include\asio\detail\config.hpp)
  . Fixed compile warning under Emscripten (ui\videoopt.cpp)
  . Standardised #include guards
- Debugger: Fixed debugger crashes when accessing memory under certain conditions (ID 07270)
