- New Clrmamepro: https://mamedev.emulab.it/clrmamepro/#downloads
- CPU
  . ARM: Fixed register-counted shifts in disassembly (arm\armdasm.cpp). Use util::sext in execution of branch instructions (arm\arm.cpp).
  . ARM7: Correct DASM of register shift op2 (arm7\arm7dasm.cpp). Use util::sext in execution of branch instructions (arm\arm7ops.cpp).
  . ATAPI CD/DVD-ROM and SCSI CD: Fixed interpretation of CD Audio control page data (machine\t10mmc.cpp)
  . Hitachi H8: Fixed divs (h8\h8.lst). Fixes the voice volumes in the (MESS) Yamaha MU100
  . Hitachi HD44780 LCD Controller
    . Explicitly define a clock for all HD44780 and derivative LCD controllers and added a validity check to ensure the defined clock is non-zero.
    . Replaced HD44780A00 rom with corrected version from 1985 datasheet (which matches videos of vintage devices). Added HD44780UA00 variant device with rom from 1999 datasheet. Added HD44780UA02 device and hook it to the (MESS) avrmax.cpp driver, as the international characters from UA02 are required for some strings in (MESS) CC2-Schachzwerg (German). Fixed two incorrectly transcribed characters from the Epson SED1278 datasheet. Cleaned up mess in ROM selection code.
  . IBM PowerPC: Use util::sext for sign extension in disassembler (powerpc\ppc_dasm.cpp). Don't generalte illegal instruction exception for LMW invalid forms (powerpc\ppcdrc.cpp and ppcfe.cpp) (ID 08791).
  . Motorola MC6801
    . Added standby pin. Save ram control reg upper bits to 'NVRAM'. Removed local implementation of m6801 standby pin and ram control reg in (MESS) Psion. Fixed SLP wakeup from Tin input capture event. Added pulse on SC1 to properly latch data from M6801 MCU port in Bubble Bobble and 'Kick and Run'. Added support for canned NVRAM. Added setter for NVRAM battery status.
    . Moved RAM, ROM and I/O areas into internal maps for all variants (including a few that lacked their own device types until now). CPU device now saves NVRAM for applicable standby areas, which only include the first part of internal RAM on NMOS variants (m6800\m6801.cpp: Hitachi HD6301, HD6303, HD63701, Motorola MC6801 and MC6803).
  . Motorola MC68705: Added preliminary support for analog input ports (m6805\m68705.cpp)
  . Samsung KS0164 audio processor
    . CPU refinements. Force source register to be the same as destination register for max/min instructions. Fixes missing instruments and eventually disappearing music in Elfin attract. Write "tst" instead of "zero |=" in disassembly (cpu\ks0164\ks0164.cpp).
    . Fixed neg/not and looping. Added volume and envelopes. Correct loop flag and pan swap. Fixed registers on nonloop so that the voice is freed correctly. Bonus usage debug output, to be removed at some point. Fixed looping calculations and removed debug stuff (cpu\ks0164\ks0164.cpp and sound\ks0164.cpp). Actually lower TX full semaphore when host reads MPU-401 buffer. This fixes elfin losing sound and the ability to coin up during attract (sound\ks0164.cpp).
  . Texas Instruments TMS32025: NEG instruction accidentally modifies the wrong status register - C_FLG is in ST1, not in ST0. Calling CLR0(C_FLG) or SET0(C_FLG) accidentally modifies ST0's INTM bit instead of ST1's C bit.
  . Toshiba TMP68301: Downshift timer irqs by one (m68000\tmp68301.cpp), fixes Poker Spirit input reading.
  . Toshiba TMP68303: Added stub for TMP68303 (bingowav.cpp, joystand.cpp and pkspirit.cpp)

- SOUND
  . Yamaha SWP30 sound chip: Use natural addresses, reorganized the meg and make envelopes and keyoff a little better. Corretly decompress the samples. Added lfo, correct issue in state readback making the program lose track of some samples. Added mixer, fixed a number of things and reverb (sound\swp30.cpp). Small advances to the disassembler (sound\swp30d.cpp).
  . Yamaha XT446 synth: Assign address maps to correct space numbers (fixes validation errors) (sound\xt446.cpp)
- DEVICE
  . ALPHA-8201: Removed unneeded zerofill
  . NAND Flash Memory/Samsung K9xxx: Only reset page address on read or program command. Added Samsung K9F1G08U0M and K9F2G08U0M (machine\nandflash.cpp).
  . Floppy
    . Implemented get_sectors_per_track() (formats\imd_dsk.cpp). Check for unrecognized options (imgtool\main.cpp).
    . Removed hard-sector floppy support (imagedev\floppy.cpp) (MAME 0.259) and workaround for index timing regression (imagedev\floppy.cpp) (MAME 0.260). Note: This has caused numerous regressions, including floppy formats not working and application hangs when using some formats.
  . Mega System 1 Tilemap: Trigger screen update on scroll register write (visible in Saint Dragon) (jaleco\ms1_tmap.cpp)
  . National Semiconductor INS8250/NS16xxx UART: Implemented transmit Break functionality. Removed scratchpad register access to 8250 class chips (machine\ins8250.cpp).
  . Netlist
    . Report line number when an exception occurs. Break up resistor arrays into individual resistors (tools\nl_convert.cpp).
    . Maximum count for 9310 is 9, not 10 (netlist\devices\nld_9316_base.hxx). Fixes scores over 200 break the score counter in Breakout [TTL].
