- Since the Commodore 40xx computers program an HSYNC width that extends past the end of
the scanline, I am clamping it in lack of anything better to do.
- Define a new MDRV_CPU_VBLANK_INT_HACK() (ZV: defined in deprecat.h) which is a copy of the current MDRV_CPU_VBLANK_INT()
- Find all the places where VBLANK_INT is used with something other than 1 interrupt per frame and change it to the new macro
- Remove the "# per frame" parameter from the MDRV_SCREEN_VBLANK_INT() and add a screen tag in its place; updated all callers appropriately.
- ZV: Added some validation of the interrupt setup to validate.c
The idea behind this is that using a VBLANK interrupt with more than one interrupt per frame in conceptually wrong.
The screen tag will allow us to move the interrupt timing code from cpuexec.c to video.c, where it really belongs.
Subject: A fix for the z80pio
Hi there,
Here is a one-line fix for the z80pio.
At the moment when the interrupt control word is sent (with interrupts
enabled), an interrupt occurs. In reality, interrupts are disabled until
the interrupt mask byte is sent.
Subject: MPU4 Changes part 2
Right, I've added a bit of CTS pin checking logic, so that the status
flag is actually set when the pin changes state.
I've also simplified the MPU4 ACIA clock logic, but it's still not ideal
(Ideally, the ACIA should only run one transmit or receive event each
time the PTM O1 pin goes high, but that's not possible right now, so I
just set the clocks as close to off as I can when the pin is low, and to
something that approximates the distance between output state changes
when it's on). There's also a few more little cleanups based on
schematics and flyers from TAFA, and an emulation of the master reset
behaviour. Incidentally, if anyone wants to see just why this isn't
kicking into life now, by all means do, since there's nothing left that
I can see that it can get hung up on, other than the video chip, and the
aforementioned ACIA logic.
Subject: uPD7801, uPD78C05, and uPD78C06 cpu cores added to the uPD7810
cpu core
This patch adds basic support for the NEC uPD7801, uPD78C05, and
uPD78C06 cpus to the uPD7810 cpu core.
This fixes the ape sprite positioning in Crazy Kong -- no more gap between feet and platform
- Merged Yamato driver with Crazy Climber
- XX Mission tilemap conversion
- Removes VIDEO_START(generic) -- no longer used
A lot of sets were added. Also System 903/905 diag ROMs.
Submitted the driver at this point because it's growing as a monster.
Parent/clone relationship for official games is not defined yet.
Changes:
- Renamed the driver to calomega.c.
- Extended the driver to support all the other Cal Omega systems.
- Switched to XTAL def.
- Fixed CPU & sound clocks based on official diagrams.
- Replaced the AY-8910 with AY-8912 to match the real hardware.
- Unified some memory maps.
- Splitted machine in sys903 and sys905.
- Fixed memory map offsets for sys905.
- Added support to the following games:
Game 7.6 (Arcade Poker)
Game 7.9 (Arcade Poker)
Game 9.4 (Keno)
Game 12.5 (Bingo)
Game 12.7 (Keno)
Game 12.8 (Arcade Game)

Jackpot Joker Poker (set 1)
Jackpot Joker Poker (set 2)
SSI Poker (v2.4)
SSI Poker (v3.0)
SSI Poker (v4.0)
- Added a list of official/unofficial games, and their states.
- Fixed a bug introduced when extended the color PROM region to eliminate colortable lenght.
- Other changes/fixes.
- Updated technical notes.
constructors to tokenized lists. For the most part
this is a non-invasive change, except for those drivers
using MDRV_WATCHDOG_TIME_INIT. In order to allow for
tokenization of attotimes, a set of new macros is
provided called UINT64_ATTOTIME_IN_x() which follows the
same pattern as ATTOTIME_IN_x() but packs the attotime
down into a single 64-bit value for easier tokenization.
Separated MDRV_DEVICE_CONFIG_DATA into 32-bit and 64-bit
versions. Added floating-point versions with configurable
resolutions.
Fixed several errors in the machine drivers which were
caught by the additional checks now done in the machine
config detokenization code.
Converted speakers into devices. Machine->config no
longer houses an array of speakers; instead they are
iterated through using the new macros (defined in sound.h)
speaker_output_first() and speaker_output_next(). Updated
all relevant code to do this.
Improved game info display with multiple screens. Fixed
bug which caused all screens to display equally.
Added typedefs for all the machine config callback
functions at the top of driver.h.
* flip_screen_x and flip_screen_y made static
* add flip_screen_x_get() and flip_screen_y_get()
* change writes to flip_screen_x from last commit to flip_screen_set_no_update()
* added save state calls for flip_screen_x and flip_screen_y
* add "int flip_screen_get(void)"
* define flip_screen flip_screen_get()
* clean up drivers with collisions
* mark write accesses to flip_screen_x with FIXME
