* 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.
Added 1:1 fallback if surface creation fails at prescale values. Changed
prescale logic to create prescale target surfaces as ARGB for YUY2
sources. Forced the use of render-to-texture over StretchRect for YUY2
sources.
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.
New games added or promoted from NOT_WORKING status
Super Football Champ (Ver 2.5O)
Super Football Champ (Ver 2.4J)
Magical Date / Magical Date - dokidoki kokuhaku daisakusen (Ver 2.02J)
Fighters' Impact (Ver 2.02O)
Judge Dredd (Rev C Dec. 17 1997)
Judge Dredd (Rev B Nov. 26 1997)
* renamed MDRV_LATCH8_MASK to MDRV_LATCH8_MASKOUT to clarify meaning
* 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.
* adds new latch device where appropriate
* increased accuracy since now all main/sound cpu communications are properly latched
* removed quite some code as a consequence
* minor cosmetic edits
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.
Bermuda Triangle / World Wars
removed ROM patches
simulated "turbo front" check
renamed bermudao->bermudaj
clarified the relationship between the four sets
made World Wars a main set instead of a clone of Bermuda Triangle
tliemaps, proper memory maps, inputs, etc.

Outrun irq fix
The level 6 irq happens only when both irq2 and irq4 line are active,
not when either is, obviously.
02136: cubeqst: from minimal UI cubeqst requires the optional CHD
02127: xymg: The game name should be Xing Yun Man Guan and "Pin Yin:"should be omitted
02138: flamegun: Debugger/Cheat System upper case cpu tag of MAIN doesn't work
02139: In audio/system16.c, there is a reference to REGION_SOUND1
02133: chindrah: The title of Zhong Guo Long?(Hong Kong,V011H) is Dong Fang Zhi Zhu(Hong Kong, V011H)
02126: corrupt CHDs are reported as missing
After an exhaustive analysis to the unknown writes, finally figured out the missing sound device.
- Added sound support to "Poker 4-1" and "Pull Tabs".
- Figured out the output ports. Documented each bit accessed.
- Added button lamps support. Created layouts for both games.
- Switched the 8255 port C to be used as output port.
- Adjusted the coin pulse timing.
- Updated technical notes.
- Splitted the driver to driver + video.
- Final clean-up.
Ikari Warriors, Victory Road
removed ROM patches
simulated "hard flags" behaviour
proper memory maps
fixed ikarijp color test
renamed dogosokj to dogosokb and loaded the correct palette PROMs
inputs, dip locations, etc.
removed NO_COCKTAIL flag since these games don't have a flip screen dip switch
02035: gwarb: Guerrilla War bootleg doesn't need a rotary joy
00869: ikari: The title screen and high score screen do not have a black background, as MAME displays.
New clones added
----------------
Ikari Warriors (US) [Corrado Tomaselli]
