- CPU
  . I80188: Improved the emulation of the 80188 to 87C451 MCU connection in order to reliably set a status bit disktool depends on
  . Intel P8098
    . MCS-96
      . Replaced I/O space with callbacks; use internal space for non-executable register file and SFR area.
      . Make SFRs more accessible to the debugger
      . Improved MCS-96 (i8x9x) disassembly: Properly decode names of directly addressed SFRs. This involves a major refactoring of the instruction execution/description unit to keep track of operand sizes and write-only destinations (since 8X9X maps numerous write-only SFRs to the same addresses as read-only SFRs). Correct operand size for immediate modes of ADDCB and SUBCB and indexed mode of MULB. Correct destination register for execution of the indexed mode of 2-argument ANDB. Correct assembler syntax of JBC and JBS (the bit specifier follows the register).
      . Added save state and miscellaneous other stuff
      . Save the int_pending register as well (but note that it is not actually cleared upon reset)
   . i8x9x: Added HSO stuff (interrupts & A/D conversion) and A/D interrupt
  . MCS-48
    . Eliminated now-unneeded arguments from p1_r and p2_r handlers
    . Fixed critical bugs with P4-P7 reads in the emulation of the MCS-48 MOVD A,Pp instruction
    . Set lower 4 bits of P2 to input during (and after) MOVD A,Pp
    . Fixed length of flags display
  . MIPS 3: MIPS3 exception handling fixes: Nested exceptions shouldn't overwrite the EPC. Nested tlb exceptions go to the general exception vector. Removed breakpoint for tlb exceptions and branch to proper vector.
  . MOS Technology M6502: Allow debugger to step over CALLF instruction (m6502\m6502make.py)
  . Motorola M6801: Use DEVCB for ports; removed I/O space and MCFG macros.
  . Motorola MC68000
    . Fixed andi, ori and eori instruction. From https://github.com/kstenerud/Musashi/commit/df0fb402a8042c964a70cb987fe6f27ff96952ef and a16bd2bb289ea2cdbb1ca11a997490774eb32b5e.
    . Improved/simplified chk2cmp2 opcode (m68000\m68k_in.cpp), fixes the helicopter in level 3 of Time Crisis can't be destoryed (ID 00777).
    . MMU (m68000\m68kmmu.h)
      . Added Special Status Word (SSW) to exception frames
      . Throw MMU configuration exception if SRP/CRP is invalid
      . Deduplicated code to set buserror details. Factor out ATC lookup into pmmu_atc_lookup().
      . Cleanups. Factor out TT register matching into pmmu_match_tt(). Simplify tt/fc matching. Removed dead code. Factor out table walking code. Replaced printf by logerror. This should be switched over to use LOG(), but can't right now because the header file is included directly in C++ classes.
      . Support short indirect descriptors and set MMU status flags in pmmu_atc_lookup(). This makes the (MESS) HP-UX 9 installer boot. Also tested that the following systems still work: Macintosh IIx with Mac OS 7 and HP-UX 7.
      . Don't try to read address bits in indirect descriptors as status bits and initialize m_mmu_tmp_sr before doing a table search. With this commit, everything required to run HP-UX 9 in mame is upstream. Tested the following machines with this mmu change: maciix with Mac OS 7, hp9k360 with HP-UX 7, HP-UX 9 and the HP-UX 9 installer.
      . Splitted m68881_ops() into subfunctions
      . Decode ptest and pflush (m68000\m68kdasm.cpp). This adds some more decoding to some of the MMU instructions.
  . Texas Instruments TMS9980A: Internalized clock divider
  . Texas Instruments TMS32025: Updated save_item
  . Zilog Z8681 CPU / Z8: Allow step-over with djnz (z8\z8dasm.cpp). When pc adjusted, move yellow bar (z8\z8.cpp).
- SOUND
  . Atari C012294 POKEY
    . Return most recent m_ALLPOT during SK_RESET. Don't count POT counters as long as SK_RESET is applied, i.e. bit #0 and bit #1 of SKCTL are both clear.
    . Remember m_allpot_r_cb() value
  . Irem GA20
    . Rewrote channel update to make data 0 act as sample terminator. Note: In all currently supported GA20 sample ROMs, samples are followed by 1 to 16 bytes with value 00 (depends on alignment). Thus I assume that this is a sample end marker. The "sample end" register might be used for something else (looping?).
    . Assumed keyon is at reg 6 bit 1 (not just any non-0 value), removed 2nd end of sample check, misc refactor and added notes.
    . Fixed frequency update algorithm
  . QSound (HLE): Saturate voice and output accumulators (The DSP16A accumulator has built in saturation). Fixes clipping in Super Puzzle Fighter II Turbo and possibly others (ID 07115).
- DEVICE

  . Intel 8243 I/O Expander
   . Fixed critical bugs with P4-P7 reads
   . Emulated the CS line, which will be useful for driving multiple 8243s.
   . Provided a separate callback for each 4-bit port
   . Eliminated space and offset arguments from p2_r and p2_w
   . Added save state
   . Release P2 output after completion of read operation
  . K054321 Maincpu-Soundcpu interface: Make it work on all speaker inputs, not just the first.
  . MC6840 PTM: Fixed dual byte mode once again. Two problems in dual byte mode: The high time flag is the same for all counters. High time flag is reset on each counter reload, but should only be reset if the timer is reload by the user.
  . Namco Custom
   . Namco C116 (Video Controller): Implemented device_palette_interface for internal palette
   . Namco System 2 ROZ (C102): Removed unnecessary device. Internalized gfxdecode (8bit data bus for ROM).
   . Namco System 2 Sprites (C106, C134, C135, C146): Get palette from graphics decode, avoiding redundant configuration.

  . PSX GTE: Use count_leading_zeros() & count_leading_ones() instead of counting manually
  . Real Time Clock interface: Added leap year support (emu\dirtc.cpp)
  . SCSI: Disable debug. The default debug settings are filling up error.log pretty quick when booting SCSI machines like (MESS) hp9k_3xx. Disable debug in the default settings, it can still be enabled if some dev/user wants to debug NSCSI (machine/nscsi_bus.cpp, nscsi_cd.cpp and nscsi_hd.cpp).

  . Paremt romset appears to be a bad dump, mark it as such. The new set 2 is very close to the parent (71 differences in each ROM) but there are enough intentional changes (including a small block of 00/ff right before the data ends) that it can't be considered a direct replacement for the bad set; these aren't all single bit changes that could be attibuted to the bitrot.
  . Lowered sound levels so that they don't clip badly due to the MSM
- Video 21: Use deal/stand for blackjack control buttons now that we're not using deal for vblank. First 4 buttons on cabinet are: bet/einsatz, start, card/karte and stop.

  . DEVICE
    . Removed MCFG usage in AY8910/2/4, M37702S1, MC6845, MSC1937, S16LF01, YM2151, cpu\pps4\pps4.h, machine\gen_latch.h, pic8259.h, pit8253.h, pxa255.h, r10696.h, ra17xx.h, roc10937.h, rp5h01.h, rtc4543.h, rtc65271.h, rtc9701.h, s2636.h, s3520cf.h, s3c2410.h, s3c2440.h and bus\isa\isa.h
    . Removed MACHINE_CONFIG_START/_END for zerozone.cpp, zr107.cpp and zwackery.cpp
  . LUA engine 
    . Added description comments for emu.item()
    . Make render.targets table a property to match the doc
    . Added background color for draw_text
    . Added pixel(x,y) and pixels() functions (Get pixel at x, y as packed RGB in a u32 and get whole screen bitmap as string)
  . Added as_hz() to emu\attotime.h. Replaced ATTOSECONDS_TO_HZ with as_hz where appropriate. On 0hz "attotime::from_ticks" return "attotime::never" instead of crashing.
  . PLUGINS: Fixed XML writer (plugins\cheatfind\init.lua)
  . hiscore.dat update (plugins\hiscore\hiscore.dat)

- Debugger
  . Added 'gp' command. gp 'go privilege' starts execution until the privilege mode changes. This can be used to break on task switches. I.e on m68k, one could do: gp { ~sr & 0x2000 && crp_aptr == 0x1234567 }. Which would execute until the privilege mode changes to user mode and the CPU root pointer is 0x1234567. For cpu code, all that is needed to make this work is calling debugger_privilege_hook() when the execution level changes.
  . Added %c to logerror. This is useful for catching putchar() like functions and printing the written value to error.log. On hp9k_3xx, i'm using this with the HP 300 test software, to log test error messages that get printed on screen to error.log, so i have the message directly after the debug messages from my driver. Example: wpset 0xfffe36be,80,w,1,{ logerror "%c", wpdata; g }.
