New System Drivers Supported (in no particular order):
------------------------------------------------------
Mac 512ke [Raphael Nabet]
BBC a&b (rename BBC) [Gordon Jefferyes, Kev Thacker]
Sharp Pocket Computer (prelim) [Peter Trauner]
Lisa2 [Raphael Nabet]
heaps of c65 variants [Peter Trauner]
XTVGA, ATCGA (prelim) [Peter Trauner]


System Driver Changes:
----------------------
- MACPLUS: Keyboard support added.  Variable memory configurations used now (a variable 
  named ram_size which can be initializzed to any value), and added variable ROM size, too.  
  Updated iwm.c to support Apple Diskcopy format : this will allow to exchange data with 
  real-world macintosh, and to use images from Mac sites.
  Fixed the RTC, and added a feature which initializes the Macintosh clock with the current 
  date and time.  Fixed some cosmetic sound core issues. [Raphael Nabet]

- SPECTRUM: Added support for .SCR (Screendump) files. Note that to ensure that the
  image is not immediately overwritten by the ROM initialisation routine the
  loading routine adds a short machine code press any key routine.  The Border engine 
  code now only uses those events with the correct ID
  instead of all events.  The specpls4 has been is now declared as GAME_COMPUTER_MODIFIED 
  .SCR files are now quickload files and are loaded by pressing F8.  The 128K machines are 
  now defined as GAME_NOT_WORKING because of the crashes when running 128K files.
  [David (aka Peter) Robertson]

- CoCo3: Now supports LPR field on INIT1 GIME register when in graphics modes, 
  fixed a bug that prevented video updates in hires 4-color modes. 
  Fixed high speed timer to have the correct speed.  Subtle tweaks to interrupt handling.  
  Special thanks to John Kowalski for info. [Nate Woods]

- CoCo/Dragon: Now supports memory size SAM register, removed 2nd fire button from 
  joysticks (only CoCo 3 has this). Video display now draws border. [Nate Woods]

- CoCo/CoCo3/Dragon: Optimized screen refresh routines accross the entire family.  
  Routing cassette audio to the speaker (AUDIO ON command in basic) now supported.  
  Documented more references about the CoCo hardware, as well as added docs for hardware 
  enhancements not supported yet. Interrupt timings now relative to clock cycles for more 
  exact timing.  Also, much more documentation. [Nate Woods]

- UK101/Superboard: Tidy up palette code, Caps lock implemented properly, Memory config. 
  4K, 8K and 40K. Added MC6850 ACIA. Cleaned up keyboard port_bits, Tape load.
  Hand crafted a superboard II graphics rom. Source YC July 82.  Swapped monitors roms, 
  wrong way around. Superboard video is 64 by 16 Max. UK101 video is 32 by 25 Max.
  To load tape images from Basic, type "LOAD", wait for the program to load, press space, 
  then RUN, LIST, etc. Some images should be loaded from the monitor, asteroids, 
  asteroids+ and scramble. When in the monitor, press L and wait for the program to load 
  and run. [Paul Daniels]

- NASCOM: Tidy up palette code. Nascom1 tape load. Memory config. 1Kb, 16Kb, 32Kb, 40Kb at 
  1000.  Test all known software. .cas done. .bin done. .nas done. Cleaned up keyboard 
  port_bits. [Paul Daniels]

- Apple1: Cleaned up code. Tidied up colour palette. Added memory configs. [Paul Daniels]

- Jupiter ace: Tidied up colour palette. Added memory configs. [Paul Daniels]

- BBC: The Hi-Res video modes have been improved with  full 6845 CRTC emulation, and 
  preliminary Teletext support has now been added. [Gordon Jefferyes]

- CBM: added c128 resolution switching, added c65 resolution switching, interlace support
  renamed c65 system to c65e, changed c64gs to pal. [Peter Trauner]

- PC: added vga resolution switching [Peter Trauner]

  features of the update to this core.  [MAME team] 

- TOOLS: Created an "osdtools.h" file that implements cross platform defininitions for 
  the tools (dat2html, imgtool, etc) [Nate Woods]
  added a info function (info is showed before the file listing in the dir command), added 
  extract command to allow conversion between file formats with create and extract 
  functions, added stream_clear to clear files (fopen(...,"w+")), added some parameters to 
  the create and put commands, c64crt c64 cartridge file support, more for professional 
  use (c64 cartridge dumper) and t64 c64 tape format support. [Peter Trauner]

- Implemented a new palette in tms9928a, computed from TI datasheet.  [Raphael Nabet]

- Cassette/wave code: Adds the ability to mute the cassette audio output.  This is done 
  by setting bit 1 of the device status.  [Nate Woods]

  in .Z80 blocks was not decoded - Head Over Heels now works. 
  .TAP files now classified as cassettes files not snapshots because of how they are 
  used - this now means they appear on Tape Control menu, corrected clock speed of 
  TS2068, fixed Issue 2/3 dipswitch implementation, dipswitch to enable/disable disk 
  drives on +3 and clones (disabling disk drives on +3 correctly shows machine as +2a

  Spectrum 128 screen refresh to use plot_pixel for a major speedup. 
  Fixed bug that created a new file if trying to use a non-existant .TAP file, modified 
  border size based on the comp.sys.sinclair FAQ (48 pixels at the left, right and top 
  and 56 pixels at the bottom of the screen, initial support for border colour - fills 
  entire border with last the outputted colour, border colour set when loading snapshots.
  Added a Border Engine to all Spectrum machines. [David Robertson]

- C65: added m4510 core, memory management changed and keyboard finished, DMA 
  controller enhanced, quickloader fixed, added floppy simulation for devices 10,11, 
  very early support of special c65/vic3 videomodes, (on the funet disks are only some 
  graphic demos, works when you change disk access (bload, loadiff) to:
  bload "name",u10
  loadiff "name",u10
  (load with dload"name",u10 or load"name",10)
  (and change the names to 8 letters in msdos.  [Peter Trauner]

- C16: emulated flashing mode of the TED chip, activated and fixed blinking. 
  Disabled blinking in multicolor modes (winter edition) [Peter Trauner]

- PC series: Changed osd_modify_pen calls to palette_change_color.  Emulation of the

  support (fixes disk support), added turboswitch functionality, changed frequency 
  to 8 MHz, removed some dipswitches.  [Peter Trauner]

- CoCo/Dragon/MC-10: Better .CAS file support, now supports cassette writes, 
  slightly better .PAK file support. [Nate Woods]

- CoCo: Now uses the standard wd179x code.  As a result, src/mess/machine/cocodisk.c 
  is not necessary anymore, implemented 63.5usec horizontal sync interrupt 
  (Dragon/CoCo/CoCo 3), implemented secondary fire buttons for both joysticks 
  (Dragon/CoCo/CoCo 3), keyboard interrupt (CoCo 3). [Nate Woods]

- CBM: cbm floppy drive simulation names for file system access changed, floppy disk 
  simulation for pet series (not working with first pet and superpet), added 8096 memory 
  expansion to cbm80 series, and cartridge/rom support in pet and cbmb series.

- Bug fix in the wave handler (when image is closed, osd_fclose() is now called 
  on the file descriptor [Nate Woods]

- Bug fix in the tape control that cause the control to give percentage erros when 
  using *.cas files. [Nate Woods]

- ImgTool: Preliminary PC Hard drive driver, better error reporting, a new command 
  ('good') that functions as a rom sorter (a la GoodNes).  CRC information is retrieved 
  from the standard MESS CRC files, the 'crc' command is replaced with 'info'.  This new 
  command will return data regarding the image if MESS's CRC files are aware of the 
  image. dir and del now can take multiple arguments. [Nate Woods]

  (Boulderdash), Tandy1000 Graphics memory switching enchanced (Lemmings), 
  Joystick changes (slow autocenter remaining), added xtcga with mf2 keyboard 
  and turbo switch, split the xtvga in xtega (vga with ega monitor), and added 
  palette handling to ega/vga. [Peter Trauner]

- C364: preliminary speech added (similar hardware in the C64 
  cartridge Magic Voice, used in few programs). [Peter Trauner]

- C128: Esc-x to switch c128 to 40 column mode. Keypad enter to switch 
  emulator to 40 column mode. In the input keys configuration menu you 
  should find several key assignments with normal (not reversed)T.  Change 
  these to another key, and the normal T will work. (in the system file 
  these keys are disabled, until I find a better solution) [Peter Trauner]

- MACPLUS: driver boots (must use the 68k C core) [Nate Woods]

- SEGA MASTER SYSTEM: Rewrite of the SMS video code, so quite a lot of games with
  interrupt problems or corrupt graphics run fine now. [Charles MacDonald]

- SPECTRUM: Added support for 128K .SNA and .Z80 files, ensured that the 48K Basic 
  ROM is paged in when running 48K snapshots on 128K machine (for improved 
  reliability and access to the default character set), changed +3 initialisation, 
  128 and +3 now set 0x4000-0x7fff to bank 5 (Now not changed if switching to shadow 
  screen), cleaned up spectrum_plus3_update_memory, fixed bug in decoding uncompressed 
  v2+ .Z80 files, and changed running speed of 128K Machines to 3.54690MHz

  50 hertz machines now really have 50 hz video refresh, c16 1551 simulation fixed 
  [Peter Trauner]

- DRAGON series: Now supports a new variant of the .PAK file format for snapshots.
  [Nate Woods]

- TI99:  Mini Memory Support (rename minimemc.bin to minimemm.bin for it to 
  work correctly), fixed a bug in banked roms when a hard reset (F3) is done, rom 
  images are now identified by their filename extensions (image order isn't important 
  anymore), no need to use NUL when no grom image, both alt -> fctn and both ctrl -> ctrl 
  added, and new rom image extensions (.c .d .m .g .crom. drom. mrom .grom).
  [Norberto Alfredo Bensa]

- A7800: Support for bankswitched carts and carts with extra RAM, added 160B video mode, 
  increased screen height to fix clipping at bottom, updated header format (details can be 
  found in machine/a7800.c), added support for light gun trigger (not the light gun 
  targetting yet, just the trigger), and removed requirment for a cartridge (since the 7800 
  starts in the BIOS it doesn't technically need a cartridge) [Dan Boris]




Other Changes:
--------------

- The core is based on MAME 0.37b2. This incorporates all 
  features of the update to this core.  [MAME team] 

- TOOLS: Disk Utility added (mkhdimg.exe) which will create variable sized HD images 
  for use in MESS.  Can create images from 9,216 bytes to 142,606,848 bytes 
  without problems.  The Western Digital 1004A that is emulated in MESS is 
  limited to 1024 Cylinders and 16 heads. The sector size is limited to 512 
  bytes as well as the sectors per track being limited to 17, this is also 
  due to the WD1004A's limitations. [Randy Rains]

- TOOLS: Generic image tool added (imgtool.exe) with the following features:
  *MAME/MESS style driver architecture; where the image formats are contained in drivers.  
   Currently, the only driver is for CoCo .DSK disk images, but there could be more.
  *Runs on the command line.
  *Commands for listing image contents, retrieving and storing files.
  *Supports images in .ZIP files.
  *"Engine" is separate from the "shell"; which gives the potential for front ends for 
   those who don't like command lines. [Nate Woods]

- Disk write support for AMSTRAD CPC [Oscar Martín González]

- Wave timer fix [Oscar Martín González]

- m6510t/m7501/m8502 CPU cores added [Peter Trauner]

- Extensive CRC updates.
