. IBM PowerPC: Fixed MCRXR UML, UM for lswx and stswx. Fixed MMU/exceptions debug messages (powerpc\ppcdrc.cpp).
. Intel 80186: Timer updates. Implemented retrigger mode. Clean up code a little and removing redundant "active_count" flag. Modernized save state registration.
. Motorola MC68HC11xx: Memory modernization and updates. Eliminated data and I/O spaces, using memory views to remap internal RAM and I/O registers within the program space. Added MC68HC811E2 type. Lay some groundwork for future internal EEPROM support. Added RTI and counter overflow flag. Register debugger state for a few more internal registers.
- SOUND
. CD Audio: Added CD media type check for special LBA 0 case (machine\t10mmc.cpp). Note: The special case of setting m_lba to 150 when m_lba is 0 is only applicable to data and mixed mode media CDs.
. CD/DA: Return LBA position as currently playing LBA (sound\cdda.cpp)
. New BSD-licensed implementation of Yamaha OPN and OPM FM audio chips, along with new device drivers for YM2203, YM2608, YM2610, YM2610B, YM2612, YM3438 and YM2151 based upon these. Corrected some ymsnd regions that had been overlooked.
. Schedule all interrupt changes via timers to ensure proper ordering. Fixes the seibu sound issue in a more generic fashion (sound\ymfm.cpp).
. Explicitly sync writes to the mode register to ensure timer control bits are handled in sync (sound\ymfm.cpp)
. Improved LFO noise behavior. Added logging (under verbose) when LFO noise sounds are played to help ID cases for further study. This will be removed prior to release.
. Fixed missing sound in Bad Dudes stage 3 boss transformation (ID 07161)
. Fixed sound effect of the van's backdoor cuts off suddenly in robocop, robocopu and robocopw (ID 06930).
. Fixed ADPCM-B processing logic. Force external mode on for YM2610. Fixes Neogeo sound playback.
. Fixed TMNT audio decoding so that it doesn't invoke undefined C++ behavior (drivers\tmnt.cpp). Also don't bother registering decoded sample data for saving.
. Implemented in-service lockout for IRQs (audio\seibu.cpp), prevent Cabal from locking up the sound CPU with an unacknowledged interrupt after reset. Fixes coins don't work when Demo Sound dipswitch is off (ID 05785).
. Fixed sound randomly speeds up and eventually dies in Boulder Dash and Sly Spy (ID 06740)
. If volume is low, don't erase output, just leave it alone (sound\ymadpcm.cpp). Fixes missing sound in Raimais.
. Fixed missing ADPCM in Hatris and Tecmo World Cup '90. Fixed YM2608 memory regions in bbusters.cpp, itech8.cpp and tail2nos.cpp games.
. Removed YM2608 and YM2610 FM output boost to match previous volume better.
. Backport active channel detection to help improve performance. Further performance improvements will come in the next cycle, but require more extensive changes (sound\ymfm.cpp). Turn off VERBOSE (sound\ymfm.cpp).
. Ricoh RF5C400: Added channels for effect outputs
. Seta X1-010: Clamp output samples to within range
- DEVICE
. Discrete Netlist: Relicensing of the GPL code to BSD-3 with the blessing of the copyright owners. Much thanks for that Couriersud, the main creatorand contributor, but also to Jonathan Gevaryahu and Sergey Svishchev. There are small remnants in machine/NL_*, specifially Breakout, Pong Doubles and Rebound that are also copyrighted by the DICE team, whoever that means. They're not critical since they only concern these drivers and not an important core subsystem.
. Floppy
. Do not crash on damaged disks (formats\upd765_dsk.cpp and wd177x_dsk.cpp). Implemented sector-based termination conditions for read commands (machine\upd765.cpp).
. Don't fault on nibble extraction on degenerated tracks (formats\flopimg.cpp)
. Reimplemented SMSC FDC37C665GT controller with floppy and parallel support (machine\fdc37c665gt.cpp)
. Turn the floppies format arrays into function calls. Create a default "mfm", "fm" and "pc" list of formats. Their contents, and which driver uses what, may need some tuning.
. Created mame_formats_full_list which gives access to all the supported formats, make floptool use it. Castool should use it too probably, but I don't want to touch it.
. Beginning of the support for preformatted floppy images. Don't fail creation because the extension is unknown. Make format determination earlier (imagedev\floppy.cpp).
. Correct index duration (2ms, not 20us) and polarity in superdrive (imagedev\floppy.cpp). Turned off log output per step (imagedev\floppy.cpp).
. Fixed an annoyingly subtle write bug (imagedev\floppy.cpp)
. Restored legacy pc_dsk floppy support for Imgtool only
. I2C Memory: Added Xicor X24C01 support
. Intel 8251 USART: Allow write_cts before device has started

- MAME
. VIDEO RENDERING SYSTEM
. BGFX: crt-geom and crt-geom-deluxe enhancements: Made spot size parameters adjustable also increased samples from 2 to 3 scanlines for crt-geom-deluxe. Made horizontal interpolation adjustable. bgfx crt-geom-deluxe: Made phosphor decay smoothly to zero at specified cutoff time. bgfx crt-geom-deluxe: Added lowpass filter. Fixed crt-geom{,-deluxe} shader compilation and recompiled shaders. Disabled lowpass filter by default by setting it to its maximum value, since it does not account for actual monitor type. We can revisit this decision in the future if better monitor information is provided from the driver.
. MEMORY SYSTEM
. Allow creators in the memory map (emu\addrmap.h)
. Fixed init_handlers in specific cases and mapping ioports in views (emu\emumem_hedr.ipp, emumem_hedw.ipp and emumem_mview.cpp)
. Keep a reference to the handlers so that installs overlapping them don't kill them (emu\emumem_mview.cpp)
. Use count_leading_zeros to simplify awidth calculation (emu\emumem_mview.cpp)
. Ensure alternatives are always created (emu\emumem_mview.cpp)
. UI
. Tell user to get the correct files (ui\imgcntrl.cpp and selmenu.cpp)
. A few incremental UI code improvements: Simplified message when toggling UI controls. Show actual configured UI toggle key, not misleading hard-coded text. Push window activated/deactivated events to UI manager. Simplified SDL window event handling code - events are pretty precise. Miscellaneous code cleanup.
. Restored validation for command-line and .ini options (disabled since 0.188) and make some errors non-fatal (mame\clifront.cpp and util\options.cpp)
. Added option to mute when unthrottled to advanced options menu. Also refactored slightly to avoid some initialisations before main.
. PLUGINS
. Fixed missing LUA API changes (plugins\cheat\init.lua and portname\init.lua). Fixed selection (plugins\cheat\init.lua).
. hiscore.dat update (plugins\hiscore\hiscore.dat)
. MULTI-LANGUAGE: Updated Portuguese-Brasil
- SDLMAME: Fixed ZEXALL target compilation (zexall\main.cpp)
- VGM player: Fixed some shortnames to match MAME. Assorted metadata fixes (hash\vgmplay.xml).
- Compiling
. Initialized some variables which were causing incorrect behaviors in DRVNOCLEAR debug builds
. Fixed MSVC build (drivers\dynax.cpp)
. Coverity (software): Fixed unused code (drivers\8080bw.cpp). Fixed crash at start due to buffer overrun (drivers\magictg.cpp) (ID 05875). Removed unused code in clone 1942 (Tecfri PCB, bootleg?) (video\1942.cpp). Fixed wrong variable (video\avgdvg.cpp). Fixed buffer overflow (video\neogeo_spr.cpp and drivers\vgmplay.cpp).
. Make core_filename_extract_base behave more robustly in degenerate cases (util\corefile.cpp)
. Fixed building with Clang 6 (scripts\genie.lua). Note: Annoyingly, Clang 6 produces warnings for unused private static data members, but does not recognise the [[maybe_unused]] attribute for them.
- Debugger
. Added 'wpsize' variable to access the data size from a watchpoint
. Fixed Debugger rewind is not functional (emu\save.cpp)
