- MCS-48 CPU
  . Eliminated now-unneeded arguments from p1_r and p2_r handlers

  . Set lower 4 bits of P2 to input during (and after) MOVD A,Pp
  . Fixed length of flags display
- MIPS 3 CPUs: 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 CPU: Allow debugger to step over CALLF instruction (m6502\m6502make.py)
- Motorola MC68000 CPU
  . Fixed andi, ori and eori instruction. From https://github.com/kstenerud/Musashi/commit/df0fb402a8042c964a70cb987fe6f27ff96952ef and a16bd2bb289ea2cdbb1ca11a997490774eb32b5e.
  . 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.

  . 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 sound
  . 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

- 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.

  . DEVICE: Removed MCFG usage in metro.cpp, machine/upd4701.h, upd4992.h, video\ramdac.h and RS232
  . Invalidate memory access caches when removing watchpoints to prevent crashes on subsequent accesses to the same memory areas (emu\emumem.cpp)

Fixed chapter numbers not in sync with the rest of the documentation. Changed the last two chapters to keep up with the document consistency. Fixed bold for nscsi_full_device.
- SDLMAME: Disable setting the SDL_WINDOW_OPENGL extra flag if -video none is set. This allows a true headless run when the environment variable SDL_VIDEODRIVER=dummy is set prior to mame/mess execution.
