also the default state, obviating the need for a default value. Removed
the "default" attribute as a result. Switching from "Off" to another
state first executes the "on" script followed by the "change" script.
Switching to "Off" from another state executes the "off" script. While
not off, the "run" script is executed each frame.
device to provide a set of ROM regions to be loaded along with the game
ROMs. It is expected that most regions defined for devices will use the
ROMREGION_LOADBYNAME flag to enable the ROMs to live in a central location.
Added new device interface selector: DEVINFO_PTR_MACHINE_CONFIG. This allows
a device to specify a partial machine driver which is appended to the end of
the machine driver for any game using that device. The intention for this is
to allow devices which have their own BIOS logic to specify CPUs and other
characteristics common to all systems using the device.
Added new ROMREGION flag: ROMREGION_LOADBYNAME, which means that if the ROMs
in that region are not found in the usual driver files, then the name of the
region will be used as a driver filename for loading.
Extended the ldcore interface structure to allow each player type to provide
its own ROM region and partial machine driver.
Moved preliminary PR-8210 emulation code from ldplayer.c to ldpr8210.c. It
is currently disabled behind the EMULATE_PR8210_ROM compile time flag.
- Better structure and organization.
- Added Super Gran Safari.
- Added improved lamps layout to Super Gran Safari and Magic's 10.
New games added or promoted from NOT_WORKING status
---------------------------------------------------
Super Gran Safari [Roberto Fresca]
removed snkwave since it doesn't seem to be used and might not be present on the pcb at all
general driver cleanup, bringing it in line with snk.c but not merging it since somthing doesn't quite fit
New clones added
----------------
The Great Ragtime Show (Japan v1.3, 92.11.26) [Stefan Lindberg]
Renamed the roms for the Japanese v1.5 from kh_0x-1 to kh_0x-2 like the other v1.5 sets. This new earlier version is the "true" kh_0x-1
Slight update to info... the PAL "VF-00" wasn't mentioned. PCB picture is at http://arcade.ym2149.com/
This rom set is not working. Bad dump??? Slightly different encryption??? Emulation issue???
Subject: Update to MC146818 RTC
Hi,
Here's a small patch to the MC146818 code, which gives a basic
implementation of the "update ended" interrupt flag.
The code is based on the behaviour of the Aleste 520EX (Russian Amstrad
CPC clone) BIOS, which periodically (about 7 or 8 times a second) checks
the flag to see if the date and time display on the BIOS setup screen
needs to be updated. Without the flag implemented, the date and time
are static on the setup screen, or if the time hasn't been initialised
(blank NVRAM) it is blank.
The BIOS function that does this basically checks bit 4 of register
0x0c, and if 0, ends there, otherwise it will read register 0x0b, sets
bit 7 of the result and writes it back to register 0x0b (presumably,
this resets the interrupt flags). Then it continues on to the display
refresh function.

Subject: a few patches
Hi,
enclosed please find a few patches that finally conclude my
input_port cleanups. I will still probably change some bit
here and there, but there will be no more massive changes
which could collide with current developments.
Notice that, after applying these patches, indexed input reads
remain only present in CPU interfaces (e.g. all the yamaha
interfaces when the sound cpu is used to read inputs) and no
more 16bit/32bit indexed read are present at all in MAME or
MESS source. Therefore, you may consider the removal of
input_port_N_word_r & input_port_N_dword_r, if you think you
don't need them anymore.
More in detail:
* patch01.diff & patch02.diff: conclude the cleanup for
drivers W -> Z
* primrage.diff: changes the start buttons with input buttons
in primrage, as per the test mode (no start button is reported)
and the control panel (see
http://www.mameworld.info/ubbthreads/showthreaded.php?Cat=&Number=161107 )
* drivedge.diff: makes drivedge ports fully 32bit and removes
the protection bit (which seems not to be used in this game, or
at least not in the port where it was tested since at least MAME
0.100)
* duplicate.diff: introduces a PORT_CUSTOM which returns a tagged
input (like a input_port_read). this could be useful for those
games which require to read the same 8bit (resp. 16bit) input in
both the upper and lower half of a 16bit (resp. 32bit) port. you
can see its use for this purpose in the modified drivers (fuukifg3,
dreamwld, cojag etc.)

fixed palette decoding of early SNK games (from marvins to athena + fitegolf). The least significan bits were assigned incorrectly.
merged marvins.c into snk.c, with all resulting fixes (removed hacks, correct shadows, scroll offsets etc)
This contains three different patches:
20080829.patch
Introducing the running_machine* parameter in a few more places. Next
step would be to make the execute_* function aware of it, if that's
OK. Also used the machine parameter in memory.c were it's available.
20080829_1.patch
The already discussed and probably being rejected removal of
dreprecat.h from debugger.h. I think this is a low-risk patch (we had
worse cleanups) and it lowers the risk of new code using deprecated
function beign introduced in MAME/MESS, because there is no invisible
inclusion of deprecat.h anymore (I think one driver - kofball.c - got
it with deprecated code).
20080829_2.patch
The last Machine -> machine conversion I had sitting in my local
tree. I know the proper way is to turn them into devices, but I still
haven't looked into that.
Each player now gets its own source file, along with new hooks
which enable more precise control over the behavior. Updated the
PR-8210 and LD-V1000 implementations to the new spec. Other
players will come online shortly.
Changed scan behavior so that it requires a constant stream of
signals to continue scanning. Updated ldplayer accordingly.
