Moved part of x87ops.hxx into new file x87priv.h. Now you only have to rename the hxx files to cpp and add the following at the top of each one: #include "emu.h", #include "i386.h", #include "i386priv.h", #include "x87priv.h", #include "cycles.h", #include "debugger.h", #include "debug/debugcpu.h" and #undef i386.

    . Fixed rw bit in address error frame. Note: RW bit actually means 1 = read, 0 = write. It was also not shift in m68000_base_device::set_buserror_details().
    . Show PMMU registers for 68020/030/040 in debugger
    . MMU
      . Handle RW bit in ATC cache properly. Added page table walk that result in BUSERROR to ATC. Fixed ptest instruction.
      . Trap if PLOAD is called with MMU disabled on MC68851. Don't skip descriptor status update for page descriptors.

      . Fixed TT register matching (test RW bit, fix masking of bits). Decode fc field for pload instruction. Fixed decoding of pload instruction.
      . Fixed compare of SUPERVISOR_ONLY bit in 8 byte descriptors. Don't change Page table/ATC state during translations caused by debugger.

- Tetris: Decapped Intel P8749H from Tetris (bootleg set 3). Matches already existing dump.
- U.N. Defense Force: Earth Joker
  . 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.

- MAME
  . VIDEO RENDERING SYSTEM: Added a DEVCB for easier hooking of the scanline timer (emu\screen.cpp)
  . 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)
  . Device Network Interface: Avoid crashing (emu\dinetwork.cpp)
- SDLMAME: Added force feedback (haptic) device (input\input_sdl.cpp)
- Compiling
  . Put #include emu.h as the first preprocessor directive in various files to support precompiled headers in Visual Studio (sound\dac.cpp, video\cgapal.cpp, video/rgbgen.cpp, rgbsse.cpp and rgbvmx.cpp)
  . Added ini/examples to dist.mak
  . Renmead flipendian_int16/32/64(mem_mask) to swapendian_int16/32/64(mem_mask) (osd\osdcomm.h, cpu\uml.cpp, util\unicode.cpp, emu\save.cpp...)
- 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 }.
