Subject: [patch] Even more reset/multisession cleanup
Hi mamedev,
These two patches try to reduce the amount of variable in .data, which
usually point to multisession/reset bugs or missing const qualifiers.
The first patch just adds const to a number of items, moving them from
.data to .rdata. The second patch sets other items to zero (moving
them to .bss), adding reset/init code where appropriate.

Found few things not right in 8080/8085 implementation.
1. ANA/ANI instruction, HF flag was not set right because error in calculation of it (missing brackets)
2. 8080 have NF flag always set (it is not used flag but bit is always set)
3. On unused ports/not connected memory values from status word were readed not 00 or FF, that is why I add it as a new internal register, it can also be buffered by some external hardware, so this could help other implementations too.

the driver's memory maps.
Reverted recent changes to MCS-48 core that were very hacky and which crashed
many games. You can now properly override the internal memory map and do
your own banking.
Also fixed 02204: masao: Memory bank error.
for this new support to work.
Clickable input support. Mostly by Nathan. A few changes from the
proposal:
* as far as the layout is concerned, states are 0 (off) or 1 (on) and
aren't impacted by the port's ACTIVE_HIGH or ACTIVE_LOW
* instead of checking each individual field for a hit, we look to see
what is hit once per frame and then just check against that; this
is faster, but does limit us to a single hit item
* added function input_field_by_tag_and_mask() to look up a particular
input_field_config by tag and mask; this makes it possible to easily
get the port default value or other information as necessary
is either DEVICE_START_OK or DEVICE_START_MISSING_DEPENDENCY. The latter
should be returned by a device if there is another device it depends on
which hasn't been started yet. Added new flag in the device interface to
indicate whether a device has been started.
Changed laserdisc interface to explicitly specify the screen and sound
devices it should route to. Drivers no longer have to manually call
laserdisc_vsync(). Instead, the laserdisc code connects up to the routed
screen device and works based on that screen's VBLANK timing. Removed
all existing calls to laserdisc_vsync().
Changed laserdisc behavior so that it completes the previous video read
and initiates the next read at the end of VBLANK instead of the beginning.
This gives player logic time during VBLANK to alter the slider position
prior to fetching the next frame.
Added new laserdisc callback for vsync begin and changed the update
callback to be called at the end of VBLANK. Also added functions to set
the slider speed, advance the slider, and directly control the video/
audio squelch. In addition, there is a new status function to get the
slider position in general terms.
Added parameter to the VBLANK callbacks supported in emu/video.c. Updated
all callers to provide a callback value.
Fixed bug that would cause watchpoints to trigger if you had a memory
window open to the watchpoint address.
Further updates to the PR-8210 ROM simulation. Still not quite there but
the system is much better understood now. Added layout to the PR-8210
which displays the state of the front-panel LEDs.
now have their tags auto-prefixed with the device's tag. This allows for
multiple instances to be present. For example, the PR-8210 laserdisc player
has a CPU with a tag of "pr8210". When it is included as a device by a
driver, the driver may tag the device "laserdisc". The resulting final
CPU tag name will be "laserdisc:pr8210". Also updated the debugger
expression engine to support names with embedded colons.
Added warnings to ensure that tags used for CPUs, sound chips, regions, and
devices follow some basic rules: they should be less than 12 characters long,
be all lower-case, and only contain letters, numbers, underscores, or dots
(no spaces). This is to ensure that they can be used properly in debugger
expressions and don't get too long or unwieldy to type (even 12 chars is a
bit long).
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.
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.
(Disassembly attached)
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.)
Regards,
Fabio Priuli
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.
* Adds MCS48_INTERNAL_ROMBANK define to header
* Drivers which need to control the ea line have to initialize banking for internal/external rom
This is not yet optimal but works as expected with existing drivers and modified mario.c
* MB8884 is a I8035 ==> 12 addr, no internal rom map
* EA line high: external access - this is "default"
The whole EA implementation is as Aaron named it, cheeky. EA=1 external rom access, EA=0 internal rom access.
But all variants are treated the same, i.e. for i8035, MB8884, I8039, the external rom is used in the same
way as the internal.
These ports are actually ports which sink current on logical 0. With a logical 1, they are in high impedance mode and may be read. The high impedance is treated as logical 1 by TTL gates connected to them.
Fixed bug in my recent DISCRETE_MIXER update.
Note: the DISCRETE_MIXER bug caused most of the speed increase of its optimization and caused some games to crash. Donkey Kong is now at 14% faster on my machine then when I started. Better then nothing.
For those keeping score dkong was at 268% on my computer before I started optimizing. It now runs at 342%. The 555 and mixer changes also speed up just about every current discrete game.

Hi mamedev,
I've been using pmd 4.2.2 to analyze the MAME codebase for duplicate
code, and it's C parser complains about useless backslashes and
dangling defines in #if...#endif sections. Here's a patch that fixes
this, and additionally fixes one real bug, a string in djmain.c was
malformed, it's curious it compiled.

Subject: Profiler related #2 (v2)
Hi, this a revised version of a patch I sent yesterday.
This one is much more cleaner, and the speed improvement is now significant

mechanism; instead, you must access the sliders via the main menu. While in
the menu, you can use the ~ key to turn off the menu display and leave only
the bar display, in order to see more of the screen.
* removed redundant and unused definitions from header file
* renamed constants and functions to be MCS48* prefixed
* re-verified all opcode behaviors and timing
* changed illegal opcodes to count 1 cycle to avoid infinite loops
* changed EA behavior so that it is a push from the driver instead of a pull on each opcode fetch
(this may change further in the future).
* reimplemented IRQ generation and timer behavior according to documentation
* updated all drivers accordingly
* fixed several uses of PULSE_LINE, which no longer works
While this isn't 'free' as tilemap_set_palette_offset() is (when the offset changes, the pixmap cache needs to be invalidated), it helps removing some redundant code from drivers.
Updated snk.c and snk68.c to take advantage of the new function.
Register access is still performed using direct memory accesses,
but the pointers are fetched through the memory system. Now you can
see i8039 RAM in the debugger. Added internal memory maps of the
appropriate size so that drivers don't need to declare this RAM.
Added a number of variants from the MCS-48 family as it was not
clear which variants had what capabilities. All documented variants
now have internal memory maps for internal ROM and RAM. Removed
memory maps from drivers using embedded ROM/EPROM/OTPROM since
they are defined by the core now.
Added some initial logic to boot and run the PR-8210 ROM (i8049)
in ldplayer.c. Currently this is disabled behind a compile-time
switch. Once this is working, the plan is to incorporate this into
the existing PR-8210 emulation, but we're not there yet.
array is involved, it seems to think it is not a constant expression.
Added MDRV_DEVICE_CONFIG_DATA32_EXPLICIT() macro which takes an explicit
size and offset. Changed MDRV_DEVICE_CONFIG_DATA32() to be built off of
this macro. Added MDRV_DEVICE_CONFIG_DATA32_ARRAY() and
MDRV_DEVICE_CONFIG_DATA32_ARRAY_MEMBER() which do explicit computations
of the offset to work around MSVC's problems.
Replicated these changes for DATA64 and DATAPTR macros. Updated latch8.h
to use the new macros.
Added gun emulation for judge dredd.
Fixed judge dredd ide emulation when building with visual studio.
Mapped primal rage 2 inputs
Mapped player 3 & 4 inputs for 1 on 1 government, these are now the default with the 6 button inputs only mapped for games that need them.
Converted AT28C16 to a device.
Added preliminary support for devices to load/save nvram.

* Added MDRV_LATCH8_NOSYNC to specify which lines do not reed a cpu sync
* Updated drivers
The MDRV_LATCH8_NOSYNC is not used in dkong.c. All latches need synchronization
because at least one line does need a cpu synchronization.
8 bit latch interface and emulation
Generic emulation of 74LS174/175, 74LS259 and other latches.
Apart from providing synched latch operation, these
latches can be configured to read their input bitwise from other
devices as well and individual bits can be connected to
discrete nodes.
Please see audio/dkong.c for examples.

Before this patch a:
cpunum_set_input_line(5, ASSERT_LINE);
cpunum_set_input_line(3, ASSERT_LINE);
cpunum_set_input_line(3, CLEAR_LINE);
loses the state of line 5. This patch fixes it by adding an explicit
but optional "virtual irq line" support to the 68k interface.
Fix m68k interrupt handling by some drivers.
Clearing the NMI line to clear all the IRQ lines worked, but it just
doesn't make sense. Now that the irq lines are really independant,
the handling can be simplified.
Subject: Profiler related
Hi,
here is a smalll patch that :
- remove include "profiler.h" to files that do not use profiling function
* emu/machine/laserdsc.c
* osd/windows/video.c
- use PROFILER_USER2 instead of PROFILER_USER1 in mame/video/tx1.c
USER1 was used twice, USER3 once. I guess that USER1 should be used
only once and USER2 used in the 2nd place
- remove unused MACRO in emu/memory.c
Best regards,
Christophe JAILLET
Subject: Various cleanups
A couple of minor cleanups sitting on my disk for a while:
- removed obsolete ENABLE_DEBUGGER occurance
- removed more unprintable characters in SH-2 disassembler
- memset() usage cleanups
- removed duplicated TMS5110 entry in sound.mak
- use machine in uigfx.c where it's already available
This handler works for both disc-only games and those with overlays.
For disc-only games, the base macro is sufficient. For games with
overlays, an additional set of configuration macros are provided:
MDRV_LASERDISC_OVERLAY - specifies update function, width, height,
and bitmap format of the overlay
MDRV_LASERDISC_OVERLAY_CLIP - specifies the visible area of the
overlay bitmap
MDRV_LASERDISC_OVERLAY_POSITION - specifies default x,y position
MDRV_LASERDISC_OVERLAY_SCALE - specifies default x,y scale factors
The update function provided to MDRV_LASERDISC_OVERLAY is identical to
a normal VIDEO_UPDATE callback, so a standard one can be used. All
existing laserdisc drivers have been updated to support this new
rendering mechanism, removing much duplicated code.
Added the ability to configure the overlay position and scale
parameters at runtime. Added OSD menus to control them. Added logic
to save/restore the data in the game's configuration file.
Added new macros MDRV_LASERDISC_SCREEN_ADD_NTSC and _PAL, which
defines a standard screen with the correct video timing characteristics
and update function for laserdiscs. Updated all drivers to use these
macros instead of defining their own screens.
Added DISK_REGIONS to all laserdisc drivers.
Added DISK_IMAGE_READONLY_OPTIONAL to support games (like Cube Quest)
where the disk is non-essential to the game's operation.
Fixed bug in identifying the custom sound driver for the laserdisc.
Updated ldverify to identify blank regions of the disc for post-
processing.
Fixed rendering 16bpp with alpha using bilinear filters (fixes
screenshots of laserdisc games with overlays).
Included support for parsing .gdi files in chdman. [ElSemi]
Added new driver for Cube Quest. This includes CPU cores for the three
bitslice processors, as well as laserdisc support for the hacked
laserdisc that was used to drive the games.
[Philip Bennett, Joe Magiera, Warren Ondras]
Note that the SHA1/MD5 for the laserdisc will likely undergo at least
one more change before being finalized.
- Moved IRQ handling front-end into recompiled code
- Added TSTM/ANDM/XORM instructions
- Added SH-1 CPU support, including lower precision on MAC.W and locking out SH-2 only instructions
Subject: [patch] Collapse timer callbacks
Hi mamedev,
The following patch collapses timer callbacks in some cases to avoid
duplicating code. In the case of crystal.c, it also refactors two DMA
handlers and shuffles the init/reset code around a bit. I noticed
while doing this that h8_itu_read8 is missing cases 0x96,0x97 which is
almost certainly a bug, but I left it alone.

Subject: [patch] Fix i386 bsr implementation

Hi mamedev,
The problem with namcos22 games losing sound when running multisession
is actually an m37710 cpu initialization bug. The attached patch
fixes it, and also collapses all the timer callbacks together as an
unrelated code cleanup.
Note: namcos22 has a lot of uninitialized state, so I wouldn't be
surprised if there are other multisession issues.
included by generic components in emu/ and thus should have no
dependencies on the MAME code.
Added new target ldplayer, which is based on MAME but serves as
a standalone laserdisc player for CHDs. Right now only the
Pioneer LD-V1000 is connected, and limited commands are available.
Each player type is a driver, so you specify the player type on
the command-line. The driver then opens the first CHD it finds
in your ROM path and uses that as the laserdisc. The intention is
that you specify the -rompath each time on the command-line, so
a typical approach might be:
ldplayer ldv1000 -rompath j:\mach3
where it will pick up the mach3.chd lurking in your j:\mach3
folder. Several basic commands are supported:
Space = play/pause
Alt = toggle frame display
Left = scan forward (when playing) or step forward (when paused)
Right = scan backward (when playing) or step backward (when paused)
0-9 = enter numbers for search
Enter = execute search to frame
item will be visible but not selectable.
Fixed bug that prevented the cheat engine from working when the
debugger was disabled.
Modified xmlfile.c to accept integer values in decimal or hex. The
default is decimal. Numbers may be prefixed by '#' for decimal
values, or by '$' or '0x' to indicate hexadecimal values. Also
added function xml_get_attribute_int_format() to return the format
of the attribute, so that it can be later replicated.
Updated cheat parser to preserve the format of attribute values
used for cheat parameters and items.
Added support for information-only cheat items, which will be
displayed in the menu but which are not selectable and have no
action associated with them. Empty information-only items are
automatically converted to menu separators.
The structures/names were getting too complex for my macros to handle. They would require hand editing and my computer is too slow to keep re-compiling.
Passes a clean compile.
Removed channels parameter from avcomp decode configuration.
Fixed incorrect test in winwork that led to spinning instead
of using the nicely allocated events we had on hand.
Forced a sound synchronization on each vsync in the laserdisc
playback. This prevents overwriting the tail end of the
buffer which was fouling up the MACH 3 audio decoding.
Removed obsolete size check for uncompressable audio data.
streams and a delta-RLE pre-encoding. Added optimized
case for the Y/Cb/Y/Cr video encoding case. Cleaned up
the code.
Updated avcomp.c to use the new huffman.c functions.
Reworked configuration options to allow for both input
and output of naturally aligned data streams. Updated
chdman and laserdsc to use the new interfaces. New
compression gives an additional 3-7% over previous
attempt and compresses the dummy CHDs down significantly.
I did not do much to the following files because I did not know the best way to name them.
aicadsp.h
sid.h
sidenvel.h
sidvoice.h
ymdeltat.h
I did not update structures only used in the src\emu\sound\*.c files. They are only used locally in the file so they were not worth the effort.
- Pass chip type around and restore Jarek's original behavior for YM2203/YM2610
- Always recalculate attack rate in set_ar_ksr, fixes Megadrive/Genesis "Batman & Robin"
What a PITA. :) I'll have to go back and do A-J to lower case the handlers to match the new structure names I already did.
Sorry Mess and other port developers, but the code should match what is stated on the official WIKI. But don't worry, I don't plan on updating anything but the sound cores.

spaces, memory names, or memory sizes. Added verification callback
to the debugger to validate CPU and memory region names, as well
as verifying that a requested address space exists for a given
CPU.
Added support for oneshot cheats (those with only an "on" script).
They are activated via UI_SELECT in the cheat menu, and pop up a
message when activated. Also added a "Reset All" item in the cheat
menu to reset all cheats back to their default state, and added
support for UI_SELECT on a non-oneshot cheat so that it resets that
cheat to its default value.
Restored previous behavior that allowed popmessage() messages to

Subject: to simplify cischeat inputs
Hi,
the enclosed diff has a twofold effect on cischeat.c:
on one side: it adds diplocations to bigrun, scudhamm,
cischeat & f1gpstar
on the other side: it removes the current hacky handling of
f1gpstar coinage dips (check video/cischeat.c to see what I
mean with hacky!) to use conditional ports instead. BUT in
order to do this, I had to add more possible values for the
PORTCOND in iptport.c. The problem is that f1gpstar has a set
of coinage settings when you set the region to JPN or USA and
another one when you set the region to EUR or FRA. To implement
this I added the following self-explanatory new PORTCOND:
ISLARGER (>), ISNOTLARGER (<=), ISSMALLER (<), ISNOTSMALLER (<=).
Only two were really needed to implement f1gpstar dips, but
the other two seemed costless to me while offering even more
flexibility to the PORT_CONDITION macro.
Also notice that the handling of conditional ports in 'TAB>Dip
Switches' menu doesn't work well (in the current source, not
affected by my patch) with contracted expressions like
PORT_DIPUNKNOWN_DIPLOC: the wrong items remain listed in the
UI menu even when you change the condition! If you leave the
DEF_STR( Unknown ) with ON/OFF cases, everything is displayed
correctly in the menu. However, I was not able to track down
what part of code is responsible for this bug.

Subject: let's say goodbye to untagged input ports ;)
Hi,
enclosed please find a few patches against 126u3 source
* port01.diff -> port09.diff : these patches continues the
cleanup of inputs in drivers starting with C (the remaining ones),
D and E. No ambiguous situations this time, so I guess there should
be no problem with the changes. Improvements include conditional dips
added to dynduke and diplocations for chinagat, chqflag, circus,
citycon, cloak, contra and dynduke
* tag01.diff -> tag09.diff : these patches add tag to EVERY input port
in drivers starting with F->Z. Notice that only tags are added, no
AM_READ_PORT, nor PORT_INCLUDE (and I saw a lot of drivers would need
it ;) ), nor other cleanups contained in the patches above. I'll keep
cleaning input next week, probably, but at least we can definitely
remove the untagged version of PORT_START :) Notice I was able to
compile the source commenting out the definition of PORT_START, so
I guess every occurrence is covered...
- new tag <comment> (within <cheat>) is read and preserved
when saved
- removed variable attribute from <parameter>; it is now
assumed to be 'param'
- added default attribute for <parameter>
Added new variable 'frame' accessible from cheat scripts. This
can be used in the conditional to prevent execution on every
frame, or for other effects (like displaying temporary messages).
Added new variable 'argindex' which is the index when processing
an <argument> with a count attribute greater than 1. Can be used
in expressions like:
<argument count="3">main.pb@(1000+argindex)</argument>
Reinstated the cheat menu. It now displays all loaded cheats and
allows for them to be activated. All known cheat behaviors should
be working now.
* moved a couple of exp(x) from _step into _reset where appropriate
* use tabulated function values for the transfer function in DSS_INVERTER_OSC

tool which walks through either an AVI or CHD capture from a
laserdisc and ensures that there are no anomalies lurking in
the VBI data.
Added new option to chdman, where if you use -createav with
a special filename (either 2:2 or 3:2) it will create a fake
laserdisc files with the equivalent cadence. This can be used
for testing until full captures are available. Most games used
2:2 apart from Dragon's Lair and Space Ace, which were 3:2.
Note that even though these files are essentially blank, they
are Huffman-compressed, meaning that the maximum compression
ratio you will get is 8:1, so they still end up ~5GB.
Moved error strings from chdman.c to chd.c, where they can be
fetched from any caller via the new chd_error_string()
function.
Updated vbiparse to improve Manchester code decoding. It now
assigns a confidence level per bit based on how solid the
data is. Also added a new function vbi_parse_all which parses
the white flag and all three lines of metadata from a
laserdisc frame. It then compares line 17 and 18 against each
other and selects the most likely candidate based on per-bit
confidence and other factors.
Added frame number display to laserdsc.c. It is off by
default, though most players can be configured to turn it on
(not sure if any actually do). It can be manually toggled via
the backslash key during playback.
Commander (MACH 3 hardware). Old laserdisc hacks are now removed.
The code now talks to the standard Pioneer PR-8210 interface. Also
removed hacky "target list" from the MACH 3 ROMs; this information
is now decoded on the fly from the right channel laserdisc audio.
Other Gottlieb cleanups:
- moved sound inputs to audio/gottlieb and included them in
all relevant drivers
- ordered input ports and ROM definitions consistently
Other laserdisc changes:
- changed PR-8210 interface to work consistently for both Gottlieb
and Stern games
- added audio callback mechanism to allow drivers to peek at the
raw audio streams
- extended the VBI parser to be even more lenient
Instead, they are identified by the region they were loaded in. This
generally means one disk per region. get_disk_handle() now takes a
region name in place of an index. Updated all callers to do this.
The SCSI modules in particular posed a challenge to make this work,
so watch out for potential bugs there.
Changed the IDE interfaces to default to choosing the region with the
same tag as the device for its master disk (assuming no slave). Added
support for specifying explicit master/slave disk regions as part of
the configuration, though slave disks are still not supported yet.
Change the laserdisc interface to no longer require a disk number or
a custom sound device. Both are now assumed to be tagged the same as
the laserdisc device. Updated all drivers accordingly.
maps and behaviors according to the schematics. Hooked up coin
counters.
Added new functions cputag_set_input_line() to assert input lines
via CPU tag instead of index.
now simply requires an AVI file input.
Relaxed VBI Manchester code clocking to allow for a little bit
of wiggle when finding the clock.
Changed laserdisc support to parse white flags and other data
from the VBI data directly, rather than relying on the textual
metadata. Expanded video frame cache to 3. Changed the way
frames are assembled to decrease the likelihood of getting an
interlaced weave. Fixed sound creation so that it is done at
reset time instead of device start, when the sound devices aren't
yet live.
Fixed bug in winwork that caused the creation of single work
items to return NULL, and thus lead to massive memory leaks when
using A/V CHDs.
