Driver Improvements:
--------------------

- Fixed ROM naming for Crazy Climber bootleg. [Brian Troha]

- Fixed background scrolling in Mustang. [David Haywood]

- Cleaned up PORT_CHEAT and tagged ports for a number of drivers. [El Condor]

- Added save state support to the Namco System 1 driver. [Andrew Gardner]

- Improvements to the Namco System 12 driver. [R. Belmont]
    - MCU is now emulated rather than HLE'd.
    - MCU peripherals mostly figured out and hooked up.
    - Preliminary sound and music are now present.
    - Inputs and coinage are now handled by the MCU, so
      all bugs related to them are hopefully fixed.
    - Fixed bug with save states.
    - sws99 and pacapp both seem playable now (not sure if
      due to these changes or smf's core work) so took off
      GAME_NOT_WORKING for them.
    - Added support for alternate ROM banking protection
      used by golgo13, so it runs now (there's a very long
      black screen at the beginning, just wait it out).  The
      gun inputs are partially supported but not working yet
      because I'm unable to figure out what format the game
      wants the data in.


Changes to the main program:
----------------------------

- More i960 bugfixes. [R. Belmont]
    * Fixed a brown-paper-bag bug where the PC and AC
      registers were getting swapped on return from
      interrupts.
    * Rewrote the frame cache mechanism using a simple
      FIFO concept.  Final Lap R now runs further.
    * Aligned reads and writes now use the full-size paths
      through the core instead of always breaking everything
      down into bytes.

- Added a core for the Hitachi H8/3002 MCU. [R. Belmont]
  It was originally written by the Zinc authors for Zinc.  I've
  fairly extensively rewritten it and adapted it to MAME
  semantics with their permission.  Cycle counts are
  probably not right because the manual's a bit
  confusing, but they're at least ballpark.

- Added a preliminary core for the Namco C352 PCM chip. [R. Belmont]
  It was originally written by the Zinc authors
  for Zinc and has been adapted for MAME by me with
  their permission.  It's not sounding real great yet on
  music, although it's better than the Zinc original.

- Added support for non-integral clock multipliers in the MIPS3
  core. [Aaron Giles]

- Refactored the Voodoo code, fixing several errors in the LOD
  calculations and the Voodoo 2 command FIFO. [Aaron Giles]

- Fixed bug that prevented changes to the default controls from
  sticking. [Aaron Giles]

  [Aaron Giles]

    Fixed bugs in the concmpo, concmpi, and modi instructions
    Added "text" and hex displays of the AC register for debugging
    Added TESTx opcodes to the disassembler

- Changed listxml to output all game flags. [Fujix]

Changes to the main program:
----------------------------

- A number of obsolete backward compatibility macros have been removed. [Aaron Giles]
  See this list for the equivalents if you have a driver that is using them:

     cpu_set_reset_line -> cpunum_set_input_line
     cpu_set_halt_line -> cpunum_set_input_line
     cpu_set_irq_line -> cpunum_set_input_line
     cpu_set_irq_line_and_vector -> cpunum_set_input_line_and_vector

     timer_suspendcpu -> cpunum_suspend/cpunum_resume
     timer_holdcpu -> cpunum_suspend/cpunum_resume
     cpu_getstatus -> cpunum_is_suspended
     timer_get_overclock -> cpunum_get_clockscale
     timer_set_overclock -> cpunum_set_clockscale

     cpu_gettotalcycles -> cpunum_gettotalcycles
     cpu_gettotalcycles64 -> cpunum_gettotalcycles64

     keyboard_name -> code_name
     keyboard_pressed -> code_pressed
     keyboard_pressed_memory -> code_pressed_memory
     keyboard_pressed_memory_repeat -> code_pressed_memory_repeat
     keyboard_read_async -> code_read_async

     install_mem_read*_handler -> memory_install_read*_handler
     install_mem_write*_handler -> memory_install_write*_handler
     install_port_read*_handler -> memory_install_read*_handler
     install_port_write*_handler -> memory_install_write*_handler
     memory_install_read*_handler_mirror -> memory_install_read*_handler
     memory_install_write*_handler_mirror -> memory_install_write*_handler

     READ_HANDLER -> READ8_HANDLER
     WRITE_HANDLER -> WRITE8_HANDLER

- Miscellaneous cleanups and refactorings done primarily to support 
  a new MESS specific feature.  Also removed some '#if 0' code. [Nathan Woods]

- New input port definitions, similar to the new memory map definitions. You can
  continue to use the old PORT_BIT, PORT_BITX, and PORT_ANALOG macros for now, but
  it is preferred going forward that all ports use only PORT_BIT, and append all
  other flags and options using the new macros. See pacman.c for an example of the
  new format. The new input ports also support tagging for easier tracking of ports,
  and the ability to import port definitions from another set. [Nathan Woods]

- Two minor fixes to xml2info so that 'mame -listxml|xml2info' matches 
  'mame -listinfo' exactly. [Logiqx]

- New option in the Windows version: -wavwrite to save sound output to a WAV file. [smf]

- Removed -listinfo option now that xml2info produces fully correct output. [Aaron Giles]

- Added ADSP2181 variant to the ADSP21xx CPU cores. [Aaron Giles]

- Added support for many more instruction forms in x86drc.h. [Aaron Giles]

- Added consistency checking for the year field. [Nathan Woods]

- Removed some silly 6502 speedups in the Atari games. [Aaron Giles]

Nintendo 8080 hardware update [Stefan Jokisch]

The driver has now been split into three parts. A few features that have been missing
in Helifire since my last update are back, i.e. the flickering colors when you're shot
and the volume decay effect (this affects the melody at the start of a game and a few
tunes that can be heard during the bonus scenes every twelve attack waves). The
starfield should now scroll at the correct speed, it's only 75% of what it used to be.
Finally, I have decided to use the color prom from Space Fever in Space Launcher, I
think it's correct.
