Note: DELETE mess.cfg!
Note: .inp record/playback does still not work currently.
New System Drivers Supported (in no particular order):
------------------------------------------------------
- Amstrad NC100 [Kev Thacker]
- CoCo 3 (with a preliminary 6309 CPU core) [Tim Linder, Nate Woods]
- SNES (preliminary) [Lee Hammerton]
- ChannelF [Frank Palazzolo, Juergen Buchmueller]
System Driver Changes:
----------------------
- SPECTRUM: Fixed +3 disk handling [David Robertson]
- COCO 3: Fixed low resolution video so that it is sensitive to the MMU; this
fixes a problem that made OS-9 Level 2 display garbage. Also fixed two bugs
that prevented horizontal scrolling from working properly [Nate Woods]
Other Changes:
--------------
- The core is based on MAME 0.37b6. This incorporates all
features of the update to this core. [MAME team]
- [DOS] File handling has CHANGED! heres a brief description:
MESS supports a softwarepath= global setting (in the [directories] section of mess.cfg)
and this is overrideable per driver (in the [driver] sections) Default for softwarepath=
is .;SOFTWARE
OSD_FILETYPE_ROM uses the biospath= setting from now on (MAME rompath=) Default for
biospath= is .;BIOS.
OSD_FILETYPE_IMAGE_R and _RW use the softwarepath= settings from now on, so BIOS ROMs can
be kept separate from carts, floppy, harddisk etc. images.
The search paths/files are for a hypothetic system driver 'sys':
extensions of carts for sys = .rom, .bin
softwarepath = .;x:/software
mess sys -cart cart
./cart
./sys/cart
./cart.zip containing cart
./sys/cart.zip containing cart
x:/software/cart
x:/software/sys/cart
x:/software/cart.zip containing cart
x:/software/sys/cart.zip containing cart
---> assume it failed, because the real extension is .bin
./cart.rom
./sys/cart.rom
./cart.zip containing cart.rom
./sys/cart.zip containing cart.rom
x:/software/cart.rom
x:/software/sys/cart.rom
x:/software/cart.zip containing cart.rom
x:/software/sys/cart.zip containing cart.rom
---> still not found, so image_fopen() tries .bin now
./cart.bin
./sys/cart.bin
./cart.zip containing cart.bin
./sys/cart.zip containing cart.bin
x:/software/cart.bin
x:/software/sys/cart.bin
x:/software/cart.zip containing cart.bin
x:/software/sys/cart.zip containing cart.bin
As you can see it might take quite some time until an image is found, with two
directories on the path already, that's why the main softwarepath= setting should be
short. If you have many, different drives/paths where you store software, you better use
the system specific overrides like this:
[sys]
biospath=x:/sys
softwarepath=x:/sys
[sys2]
biospath=roms
sofwarepath=z:/somewhere/sys2
However, if you have a 'complete set' you would be done (mostly) if you only change the
[directories] setting for biospath= and softwarepath= to the drive/path where your
mirrored files are.
One extension to the searches that might make sense would be to also look into a
path/ext/cart.ext directory, that means you could have subirectories for eg. dsk, cas,
vz, bin or whatever the extensions of the system are. [Juergen Buchmueller, Ben Bruscella]
- Many fixes to cheat engine [Cowering]

- NES now gets correct mapper info from nes.crc (if present) [Cowering]
- Genesis/Megadrive now gets correct CRC info for .smd and .md files [Cowering]
- new function osd_select_file() added [Brad Oliver]
- IMGTOOL: Fixed a bug that caused saving a file into an image to error if that
file was in a different directory. Also fixed a bug that would cause crashes
when reporting certain types of errors [Nate Woods]
- CRC and sysinfo updates will now be appearing at the official MESS homepage:

New System Drivers Supported (in no particular order):
------------------------------------------------------
- NES (pal) [Brad Oliver]
- Famicom [Brad Oliver]
- Mattel Aquarius [Paul Daniels]
- PCW8256, and many clones [Kev Thacker]
- PCW16 [Kev Thacker]

- Sharp PC1402, PC1350 [Peter Trauner]
- Atari2600 (preliminary) [Lee Ward]
System Driver Changes:
----------------------
- NES: Now features battery support and vastly improved PPU emulation - compare Kirby and
RC Pro Am.
* Palette is no longer hardcoded - it is mathematically generated. It may need some
formulaic tweaking, but it's pretty accurate.
* Games like GI Joe Atlantis Factor are working again, the NES Test cartridge no longer fails.
* There is a compile switch to emulate the color intensity used in Chris Covell's "Wall" demo.
It's off by default because it requires 16-bit mode and the sprite blitters need rewriting to
support 16-bit. Still, you can enable it to see the demo run as it was intended.
* Many mapper fixes: mapper 18 irqs should be close, mapper 19 added, the mid-20 Konami
mappers are nearly 100%, and some of the mappers in the 60's are much more accurate.
*Super Mario 3 _finally_ works! Excitebike also works again, and elite and PAL games,
Elite will draw properly -- but only using the PAL NES emulation.
* Fixed some more timing errors, Bayou Billy sine wave looks perfect now.
* low/high sprite priorities fixed. Super Mario 3 uses low priority sprites to mask out
pieces of high priority ones.
* low-priority sprite/background transparency problem fixed (see Jaleco's Bases Loaded 3)
* Mapper 5 is much better, although some interrupt problems remain.
* Mappers 9/10 are _almost_ perfect.
* Fixed mapper 16 - it was completely wrong.
* Fixed rendering problems in mapper 68 (Afterburner 2).
* Fixed mapper 69 (Batman: Return of the Joker).
* Mapper 70 (arkanoid 2 j) works, but is it right? It starts up on round 0, which appears
to be the last round and not the first.
* Implemented some Taito mappers (80, 82).
* Implemented Konami VRC7, minus OPL (mapper 85).
* Preliminary support for the zapper via a fake dipswitch. Collision detection isn't
working yet.
* Modified sound core to read dpcm samples from the right place in memory. Added clock
specifier and read/write callbacks for register $14. NES driver now hooks into this for
sprite DMA.
* Zapper support, configurable via the fake dipswitches. Most games look for it connected
to the 2nd input port, not the first. Tested it with Duck Hunt and Hogan's Alley. If any
other zapper games don't work, let me know and I'll beat them down.
* 4-player joypad support, also configurable via the fake dipswitches. For best results,
set both ports to the double setting. I tested it in Gauntlet 2 and RC Pro Am 2. Again,
let me know if it's busted in any other 4p games.
* Fixed sprite priorities for the last time. I swear it's really working now. ;-) As a
side effect, the rendering code is a bit faster than before.
* More mapper fixes/additions.
* Added support for Famicom Disk System. Split up the main NES driver into NES and
Famicom. Only the Famicom supports the disk system, because that's the way it is in real
life. Press p1 button 3 to cycle amongst the disk sides. Once you switch a side, you may
need to wait a second or two for the switch to be recognized. Let me know if any games
fail to see the switch. Disk writing is not yet supported.
* Added preliminary support for the Arkanoid paddle. It's pretty busted at the moment.
* Fixed a small PPU bug regarding reads from the chr-gen ram portion of the ppu.
* Correct display of left-most column when it has been programmatically disabled -
see SMB3.
* Added some more mappers, some of which aren't working fully.
* Fixed mapper 40 (SMB2j pirate) - it should be close to 100%
* Fixed some issues with the disk support. It now supports that stupid padded format with
the useless header in addition to the other format.
* DPCM samples fixed (now hear SMB3 in all it's steel drum glory).
[Brad Oliver]
- COCO: Now using schedule_full_refresh() and PAK loader fixes applied [Nate Woods]
- KAYPRO: Keyboard fixed [Juergen Buchmueller]
- PCW16: emulation is fully working. To run this you need the "OS rescue disk". The system
rom is contained on the OS rescue disc and you will need this to install the OS. This
disc is available on the net, do a search to find it. [Kev Thacker]
- PC: improved PC-AT keyboard emulation to work with PCW16. Should work better with PC
emulation too. Improved PC-Serial Mouse emulation to work with PCW16, improved PC FDC
emulation to work with PCW16. FDC now works as before but uses same nec765 code as the
Amstrad and Spectrum drivers. More software that programs the FDC directly should work.
Changed PIO code in PC-XT to use 8255 emulation. Seperated PC-LPT code to be used with
PCW16. seperated and improved PC-Serial code. Works with PCW16 now, and interrupts are
set/cleared correctly. seperated pc floppy disc handling code for use with PCW16.
Fixed tandy1000 problem, pc's changed to use pckeybrd, split pc_cga, pc_mda, pc_t1t from
pc and fixed atcga, xtvga init/blink problems. changed uart8250 and pc_mouse interface,
realtime clock fixes and improvements (starts with current time) better vga retrace
emulation, fixed mouse problem in pc's (was a simple inputport configuration problem)
[Kev Thacker, Peter Trauner]
- SPECTRUM: The border displaying code is now includes a full refresh flag. 128K port
decoding updated (still not exact on +3) - Sound now works on Zub 128K.
[David Robertson]
- A7800: TIA sound update, which replaced the fixed/rand() polynome initializations to
ones based on the same algorithms that are used in the Pokey driver.
[Juergen Buchmueller]
- TRS80: Split the ROMs into the 4K sizes they originally had
trs80.rom -> trs80.z33, trs80.z34 and trs80.zl2
sys80.rom -> sys80rom.1 sys80rom.2 and sys80rom.3
added an trs80alt driver for the 'R/S L2 BASIC' (its an original ROM with a shorter
bootstrap message and some code modifications). IO_CASSETTE now only loads *.cas files in
SYSTEM format and IO_QUICKLOAD is used for files in *.cmd format (disk excerpts)
[Juergen Buchmueller]
- Commodore: m65ce02/m4510 timing corrected, fixed rtn, plp, rti, eom, added m65ce02 aug
c65 speed improvements, ega/vga speed improvements [Peter Trauner]
- AMSTRAD: Changed video hardware code to use 6845 CRTC code. Also added Eventlist code to
the Amstrad video hardware code. It will record colour changes, mode changes and crtc
register writes. This means support for multi-modes on the same screen, colour changing
effects, and demos. There is a second method which updates between I/O writes that
would affect the screen. The rendering method can be chosen with a compile switch.
Also added correct opcode timings for Amstrad using new cpu_setcycletable, this
means raster effects are now correct. Also added emulation of the Multiface hardware.
It requires a rom (optionally loaded). You must enable it in the dipswitches. When
enabled F1 will be the "stop" button. [Kev Thacker]
- ZX: Fixed ZX80 palette: it's black on white, and not viceversa. [Stefano Priore]
- CoCo/Dragon: Fixed a bug the CoCo 3 horizontal scroll so Crystal City is partially
playable now, converted the CoCo/Dragon driver to use an include file, moved PAK loading
code into a new src/mess/formats directory [Nate Woods]
- PDP/1: Fixed a null pointer access if no image is loaded. [Nate Woods]
- PC1401/1402/1350: Artwork support added [Peter Trauner]
- PCW: Added sound emulation. [Kev Thacker]
- PCW/CPC/SPECTRUM: Fixed some bugs in the disk image handling code used in
the Amstrad CPC, Amstrad PCW, and Spectrum+3 drivers [Kev Thacker]
Other Changes:
--------------
- The core is based on MAME 0.37b5. This incorporates all
features of the update to this core. [MAME team]
- NEC765: improved and more commands added, supports DMA access. Can handle
images with copyprotection. A lot more software should now run on the
systems that use it (PCW,Spectrum, Amstrad,PC and PCW16). [Kev Thacker]
- 6522via Bug fix [Gordon Jefferyes]
- Optional ROM support. It can be used in MESS for BIOS ROMs for peripherals for which
you'd like to provide a valid crc32 without requiring the ROM. [Brad Oliver]
- Imgtool: Added a CRC command to imgtool so output image information in .crc format
basename()'s the command name when printing error info, Fixed a typo in the usage
examples, added a very rough imgtool.txt to document imgtool [Nate Woods]
- Added new endian macros [Nate Woods]
- DeviceIO bug fixed for most drivers [Juergen Buchmueller]
- CRC and sysinfo updates will now be appearing at the official MESS homepage:

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]

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

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]
- SC61860 CPU core [Peter Trauner]

- SPECTRUM: .TAP loading on TS2068 now works, and fixed bug where the last byte
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
on start up menu). implemented TS2068/TC2048 64 column and hires modes, rewrote
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

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.
[Peter Trauner]
- MTX: Cassette support can now handle multiple files in the same image, and country cde
(CTYLST) Dipswitches now implemented. [Lee Ward]

('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]
- Extensive CRC updates.

System Driver Changes:
----------------------
- PC: Mouse now very usable, PC CGA scrolling support in 320x200x2 fixed
(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
[David Robertson]
- COMMODORE: cbmdrive (memory freeing) fixed, cia6526 tod fix, c128fra fix,
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 Martφn Gonzßlez]
- Wave timer fix [Oscar Martφn Gonzßlez]
- m6510t/m7501/m8502 CPU cores added [Peter Trauner]
