  . Hitachi HD44801: Removed port enum (cpu\hmcs40\hmcs40.h)
  . Hitachi SH-2: First pass over SH7604 SoC refactoring. Fixed division unit overflow flag clearance.
  . Intel C8095 and Intel P8098: Added baud rate register (mcs96\i8x9x.cpp)
  . Intel I8086: Delay interrupts for one instruction after sti
  . Intel I386/Athlon: Removed some MSVC warnings. Fixed up some commented out testing code (i386\cache.h).
  . MCS-48: Added (unemulated) CMOS IDL opcode (mcs48\mcs48dsm.cpp). Update documentation. Further distinction of UPI variants.
  . Motorola M6805: Flag fix. CLRX doesn't clear the carry flag (m6805\6805ops.hxx).
  . Motorola MC680xx: Accurate byte-smearing write behavior for 32-bit members of the M68K family. Apply byte smearing to PMMU as well. Fixed PMMU translation error that broke (MESS) Macintosh II (m68000\m68kcpu.cpp).
  . Zilog Z180: Separated out internal registers by function and get rid of a lot of not-so-useful macros
- SOUND
  . TMS5220: Switch the log mask define comments to be above the defines. Adjust delay time between /RS going low and /READY being set. Note: The datasheet doesn't list this time exactly, but something close (time between /RS going low and the data being valid on the bus). It's measured in usec, not clock cycles.
  . Yamaha YMF278B OPL4: Eliminated clock macro
- DEVICE
  . 6821 PIA: Fixed method names in comments. Removed unused set_port_a_z_mask calls and m_port_a_z_mask variable. For port A reads, only use the DDR for reading pins unless. Provide an override option when a device depends on slightly undefined behavior of an external device driving the pins and changing the value read. One board seems to need this (coinmstr). I don't have the schematics, but it seems it uses this to check its meter operation.
  . DECO MXC06 Sprite
    . Fixed regression (MAME 0.210), fixes Birdie Try sprite problems on the title screen and during gameplay (ID 07345).

- MAME
  . VIDEO RENDERING SYSTEM
    . Moved additive blending function into emu\drawgfx.h. Added priority related copybitmap functions. Fixed spacings. Added priority related copybitmap and draw_scanline function is sprite like priority handling(prio_*) and tilemap like priority handling(primask_*). These are helpful for priority related bitmap/scanline drawing routines (emu\drawgfx.cpp). Added variations of priority related pixel draw functions. Fixed spacings (emu\drawgfxm.h). Added example usage for prio_copybitmap to video\realbrk.cpp and add_blend_r32 to video\hng64.cpp.
    . Added packed and raw case of generic gfx layouts. Added example usage to f1gp.cpp, pgm2.cpp, powerins.cpp and psikyosh.cpp.
    . Added screenless base class (devices\video\pwm.cpp/h). Make screenless a device. Use pwm_display_device for (MESS) hh_tms1k.cpp, tispeak.cpp and tispellb.cpp.
    . Default SVG region (emu\screen.cpp)
    . Since value is unsigned, it will never be lower than zero (emu\render.cpp).
    . Solve the quit-on-minimize problem (render\drawgdi.cpp, drawnone.cpp, drawogl.h and drawbgfx.h)
    . Fixed alt-tab crash in D3D mode (render\drawd3d.cpp; Launch MAME in full screen, then hit ALT+TAB which brings up a menu of other active windows but instead makes MAME assert) (ID 06264)
  . MEMORY SYSTEM
    . Fixed subtle memory subsystem bug (emu\emumem_mud.cpp)
    . Make submaps work with address-shifted spaces. Note that submaps are now assumed to use an address shift of 0. It is possible, though unlikely, for this to cause some breakage (emu\addrmap.cpp and emumem.cpp).
  . PLUGINS: Changed autofire config directory to homepath (plugins\autofire\autofire_save.lua and init.lua)
  . Eliminated legacy callback syntax (template  devcb_base &set_?_callback/handler(?) { return...}; emu\devcb.h, screen.h, cpu\nec\v25.h, s2650\s2650.h, machine\74175.h, ataintf.h, cr511b.h, eepromser.h, i8212.h, i8251.h, namcos21_dsp_c67.h, pci-ide.h, sound\2203intf.h, 2608intf.h, 2610intf.h, 2612intf.h, 3526intf.h, 3812intf.h, es5503.h, ics2115.h, mos6560.h, msm5205.h, nes_apu.h, s14001a.h, spu.h, video\psx.h, v9938.h, audio\dsbz80.h)
  . Defaulting to empty search path if null (emu\machine.cpp)
  . Added focus next/previous input types, will be hooked up later (emu\inpttype.h and ioport.h).
  . Device Network Interface: Added loopback control (emu\dinetwork.cpp)
  . Fixed ppc64el issue. This is probably due to the fact that IBM 128bit long double format is not constant folded. Slighlty rewrote ""_kHz_XTAL(long double clock) and ""_MHz_XTAL(long double clock) the way ""_kHz_XTAL(unsigned long long clock) and ""_MHz_XTAL(unsigned long long clock) are written. Compensate for floating-point rounding errors when converting to integer value (emu\xtal.h).
  . Make more use of the NODEVICE_LAN flag
  . Adding a -version command line argument to get the current build version (mame\clifront.cpp)
  . Validity
    . Be more verbose when validating device type (emu\validity.cpp)
    . Fixed -validate errors detected and assured it passes xmllint (hash\cd32.xml)
- Linux: Overhaul to advanced gun instructions. This cleans up spelling and other issues in the original text. This work is still prototype and will probably require fine-tuning (docs\source\advanced\linux-lightguns.rst).
- Compiling
  . travis.yml: Added libxi-dev to Travis Linux Config
  . Fixed VS LLVM configuration: dxsdk was missing from includes. winmm was missing from libs. Narrowing warning was silenced for VS, but not from vsllvm, where it leads to an error in menu_video_options::handle() (scripts\genie.lua and osd\modules.lua).
- Debugger
  . Fixed fatal error when attempting to set watchpoint covering unaligned portions of two adjacent native words (debug\debugcpu.cpp)
  . Correct address shifts for UNSP and upd7725 (tools\unidasm.cpp)

  . MCS-48: Workaround for interrupt latency issue. A better fix for the JNI problem. Documented a few more variants (mcs48\mcs48.cpp).
  . MCS-51: Disassembler update: Restored some 8052 SFR and bit names that were inadvertently omitted for more advanced models. Added a few more T2-related names. Added i8xc51fx and i8xc51gb disassemblers with additional SFR and bit names. Removed i80c51 from unidasm (actual differences from i8051 are not significant).
  . MIPS-I: Added bus error line
  . Mitsubishi M37710S4

  . Zilog Z8681: Fixed Z8 calculation of half carry flag. Z8671 BASIC no longer prints "12" when the result is 18 (z8\z8ops.hxx).
- DEVICE
  . 6522 VIA: Changed most mappings into m()
  . Cassette image: Cleanup and fixed a few minor but annoying bugs: Create new tape, hit Reset: fatal error - internal error. Load empty file to record onto, same error. Randomly have to hit Play a number of times before it takes. Randomly tape "plays" silently with the motor off.
  . Floppy
    . First stab at weak zones handling (imagedev\floppy.cpp)
    . Surpass some copy-protected tracks (formats\dsk_dsk.cpp)
  . Intel 8155 RIOT: Update port outputs upon mode change

  . SCSI
    . Moved modern SCSI CD/HD devices into devices\bus\nscsi. Default list of nscsi devices.
    . Class overhaul: SCSI slot options are no longer required to implement nscsi_device themselves. Instead they implement nscsi_slot_device_interface, which contains a finder for a nscsi_device. This is to accommodate LLE SCSI drives with their own LSI interface chips. SCSI bus device connection is now done through device_resolve_objects rather than device_config_complete (The pessimized code to access the device finder is because that will not have been resolved yet). Added a validity checking method for nscsi_connector.
- bfm_sc5sw.hxx: Added PCBs ASCII layouts

- itech32.cpp
  . Reduced logging noise
  . Use generic latch device for sound communications and added second latch to 68EC020 systems. This is an attempted fix for (ID 07098; Incorrect sounds playing during gameplay in all Golden Tee sets). It might not be enough, but it at least undoes the ITech32 machine config modernization in MAME 0.201 and thr inversion of CPU order.
- ksys573.cpp: 'Konami 573 digital I/O board' now correctly reports the actual number of samples already played (instead of rounding up by one discrete mpeg frame in advance and disregarding samples that have been copied to the stream but not yet actually played) (sound\mas3507d.cpp).
- m72.cpp: Use buffered_spriteram16_device for buffered spriteram. Reduced duplicates, runtime tag lookups and unnecessary lines. Simplified handlers. Use seperated address map related to config and shorter/correct type values. Correct PCM sample rates. Rounding fixes.

- midtunit.cpp
  . Added MIDTUNIT_LOG_PNG define to log unscaled 32bpp PNGs of all DMA draw calls. Added optional debug #define to emit JSON metadata about each DMA draw call. Removed #define-based PNG/JSON logging and moved it to a debugger command (video\midtunit.cpp).
  . Clarified the ROM offset values in metadata by splitting into byte and bit offsets
- model2.cpp: Changed .lay workaround, also fix lightgun cursor not showing in Virtua Cop (create "screen" before "ioboard").
- mpu5.hxx: Added some game hardware info and PCB ASCII layout
- namcos2.cpp: Drop ROZ optimization hack, which was causing missing backgrounds for Phelios.
- nemesis.cpp
  . Gradius (Bubble System)
    . Fixed 72-scanline timer for bubble system hardware, which fixes the logo draw speed, respawn time and other issues in the Bubble System version of Gradius. Fixed the sound Z80 speed, which was too fast on the pre-Salamander hardware and fixed the sound cpu timer to run at the correct rate based on the Nemesis schematics. Added lots of hardware notes and TODOs based on tracing and PCB pictures.
    . Demoted Gradius (Bubble System) to MACHINE_UNEMULATED_PROTECTION. Note: Game requires ~16 seconds to resume after each death (way too much?), has missing gfxs on title screen logo and still needs proper MCU emulation.
  . Documented PCB ID for Salamander/Lifeforce; note possibly undumped speech ROM for clone Lifeforce (Japan).
- nmk16.cpp: Reduced duplicates. Moved Afega related stuffs into afega_state. Cleanup Twin Action OKI bankswitching routine. tdragon2 and raphero has address-swapped main RAM; related to protection? Simplified handlers. Reduced unnecessary lines and runtime tag lookups. Fixed spacings and namings. Use shorter/correct type values. Correct sound output (Afega games aren't have a stereo output).

Fixed tilemap RAM bankswitching behavior - mark tilemap dirty when RAM bank is changed. Fixed sound output balance. Fixed metadata related to regional notice. Correct clocks related to on-board XTALs.
- pgm.cpp
  . Added configs related to ARM7 speed and on-board XTALs. Reduced duplicates and unnecessary lines. Added notes and version infos. Fixed metadatas.
  . Correct 'The Killing Blade Plus' ARM7 clock (machine\pgmprot_igs027a_type3.cpp). Reference: http://www.gc8tech.com/
- playch10.cpp and vsnes.cpp: Fixed light gun regression in Duck Hunt (PlayChoice-10), Hogan's Alley (PlayChoice-10), Wild Gunman (PlayChoice-10), Vs. Duck Hunt and Vs. Hogan's Alley (ID 07331)

- MAME
  . VIDEO RENDERING SYSTEM
    . Make layout format more flexible:
      . There is no longer a concept of "layers" - there are only screens and elements
      . Elements are now instantiated with 
      . Screens and elements can have explicit blending mode specified with blend="..."
      . Default blending mode for screens is "add" and default for other elements is "alpha"
      . Other supported modes are "none" and "multiply"
      . This removes the options to enable/disable layers individually - use views instead
      . Legacy layouts can still be loaded and support won't be removed for at least a year
      . The current artwork model is over-stretched. It's based on a Space Invaders cabinet model, and isn't applicable to a lot of the systems MAME emulates now. The fact that MAME has to switch to an "alternate" mode to deal with games like Golly! Ghost! without requiring pre-matted bitmaps shows that the Space Invaders model wasn't even adequate for general arcade use. It shows in that for a lot of the systems that heavily depend on artwork, people just seem to randomly choose layers for elements until they get something that works. Also, the fact that MAME will switch to an alternate (Golly! Ghost!) mode depending on the combination of elements is a trap for people learning to make artwork. There are cases that the current approach of implying the blending mode from the layer doesn't work with. Examples include LEDs behind diffusers (requires additive blending for layout elements), and mutliple stacked LCD panels (requires RGB multiplication for screens). For configurability, it's now a lot easier to make multiple views using groups. For example, if you want to make it possible to hide the control panel section of your layout, you can put the control panel elements in a group and create views with and without it. I will gradually migrate the internal artwork to use the new approach. I have an XSLT stylesheet that helps with this, but I'm not comfortable adding it because it isn't a complete solution and it still requires manul steps. I wanted to get the re-worked pointer handling done sooner so I could push them both at the same time, but unfortunately various things have prevented me from progressing as quickly as I wanted to. Sorry guys, that stuff's going to have to wait.
      . Don't crash when a layout references a conditional I/O port field (emu\rendlay.cpp)
    . PWM Display: Fixed savestate problem (video\pwm.cpp)
    . Removed TEXFORMAT_PALETTEA16
    . Some simple screen ind16 -> rgb32 conversions (drivers\kinst.cpp and sbrkout.cpp)
    . Fixed fatalerror with PRIMFLAG_TEXFORMAT(TEXFORMAT_RGB32) | PRIMFLAG_BLENDMODE(BLENDMODE_RGB_MULTIPLY). Renamed draw_quad_argb32_multiply to draw_quad_rgb32_multiply since it actually doesn't multiply per pixel alpha (emu\rendersw.hxx).
    . Handle layouts that wanted screens to be opaque. if you have a layout with only screens and need to add, mark them explicitly. haven't tracked down the lightgun pointer issue yet.
    . Additional fix to MAME slowdown on screenless view (MAME 0.207: Stop frameskipping constantly on screenless systems with frameskip=0 and don't use iter count).
  . DEVICE: Reverted unnecessary change from MAME 0.211 in emu\devcb.h (isnull() checks the list of unresolved functions along with the list of resolved ones, so resolve_safe() doesn't really need a return value as long as it is called second).
  . UI
    . Changed the various usages of UI_*COLOR to be calls to frontend\mame\ui\moptions.h. The various UI_*COLOR macros were implemented as calls to decode_ui_color, which cached the values for the various options in a static array, which was obviously a gross hack. This refactoring is strategic because I am trying to confine awareness of mame_ui_manager to code in frontend\mame\ui, and the implementation of decode_ui_color() relied on the ability to access mame_ui_manager as a singleton from outside this code. Created a ui_colors object, so that queries for UI RGB values would not always require parsing strings. Replaced UI_TARGET_FONT_[ROWS|HEIGHT] and UI_BOX_[LR|TD]_BORDER macros with property calls. These macros were implemented with a call to a function (get_font_rows()) that opportunistically stashed the results of option accesses in static variables; in other words, a gross hack. Because get_font_rows() attempted to access mame_ui_manager as a singleton, it was an obstactle to providing an alternative implementation of ui_manager. Removed stray debugging cruft that found a way into the other PR. Converted a few more options().zyx_color() to colors().zyx_color().
    . Disable ui startup screens for "-video none"
    . Fixed segfault when trying to access some image option that does not exists (emu\emuopts.h and image.cpp) (ID 06655) (ID 06654) (ID 06677) (ID 06880)
  . LUA engine
    . Added video:size(), video:pixels() and screen:refresh_attoseconds(). pixels() and size() correspond to internal game resolution covering all screens and internal pixel colors. the same values are used for bitmap dumping. similar things available for screen_device lua library take into account final UI resolution and colors, so they can't be used when accurate framebuffer is needed. refresh_attoseconds() allows to calculate precise numerator and denominator for framerate.
    . Moving paste() from mame_ui_manager class to natural_keyboard class, exposing to LUA. Exposing sound_manager and natual_keyboard object to LUA. Making video_manager::effective_frameskip() public and exposing via LUA. Saving snapshots in LUA now supports absolute paths. Exposed various methods/properties on device_image_interface to LUA: Exposing must_be_loaded and display() on device_image_interface's LUA implementation. Exposing device_image_interface::create() to LUA. Exposed the ability to set input seqs on ioport_field in LUA.
    . Exposed miscellaneous ioport_field methods and properties to LUA: ioport_field::type_class(), ioport_field::seq(), user values on ioport_field and writing user values on ioport_field. Exposing device_image_interface::[brief_]instance_name() to LUA. Added ui_input_manager::[set_]presses_enabled() and exposed to LUA.
    . Created a -skip_mandatory_fileman option (skip prompting the user for any mandatory images with the file manager at startup).
  . Sound
    . Suggestion for very-low-latency mode on PortAudio. Needed to keep audio in sync when playing rhythm game machines such as Konami System 573. This is because the lowest audio_latency currently supported (audio_latency 1) introduces at least 10 ms of variable latency. I am unsure how to go about this without breaking backward compatibility so I set it to work only when audio_latency is 0 (which was previously ignored by mame itself and was treated equivalent to audio_latency 1). I am aware that setting audio_latency to 0 is not supported by many mame frontends, but this change seems natural. Otherwise, would it be better to add a new mame.ini option, or to automatically enable this low-latency mode when pa_latency is set lower than, say, 0.01 (10ms), which would break people's configurations if they already rely on the old behavior? (sound\pa_sound.cpp).
    . Get rid of sound\wave.h usage
  . Save state: Print all duplicate savestate entries found rather than bailing after the first one (emu\save.cpp)
  . Screenshot/AVI
    . Modernized imagedev\snapquik.cpp delegate and removed MCFG macro (quickload; drivers\jaguar.cpp)
    . Added functionality to read RGB24 and YUV420p uncompressed video frames (util\aviio.cpp)
  . Removed generic/slot macros
  . Removed a stray (likely vestigial) variable from windows\window.cpp. Changing win_window_info::draw_video_contents()'s update parameter to be bool and winwindow_has_focus() to return bool.
  . hiscore.dat update (plugins\hiscore\hiscore.dat)
  . MULTI-LANGUAGE: Updated Turkish translation
- Debugger
  . Fixed calculation of TMS34010/020 shifted memory addresses for debug save and load commands (debug\debugcmd.cpp)
  . Added CMDFLAG_CUSTOM_HELP, in order to flag custom device-specific commands that have custom help text (debug\debugcon.cpp).
  . Fixed bug in error-log window. New Memory Window would clear the log (debugger\win\debugwininfo.h and logwininfo.h).
  . Updated debug media menu to latest version (debugger\win\consolewininfo.cpp)
