* PALETTE_INIT no longer has a colortable parameter
* removed game_colortable and remapped_colortable from machine_config
* updated a few stragglers that still referenced these fields
* removed tile_draw_colortable from tilemap.c
(From Zsolt): Added support for the new colortable object in the palette viewer
Changed the input port tokens to use a union instead of casting everything to FPTR.
In the future, C99-enabled compilers will be able to achieve type safety with
designated initializers.
Subject: Assorted dumps and other fixes
Hi,
I have enclosed a patch file that:
* Fixed some of the rom dumps for Double Dragon 3 (Some of the dumps were based of the bootleg and not the original.) and updated the name and location to actually match that of a real board
* Updated the dip switches for Combatribes to actually show their position on the physical board.
* Dumped the six GAL's on Battletoads and updated the existing rom names to make their locations easier to understand.
* Updated the dip switches of Battletoads to actually show their position on the physical board.
* Added placeholders for pals that need to be dumped for the various games in mcr68 driver. I got the information by looking at the manuals except I couldn't find a manual for Arch Rivals or Pigskin 621AD though I'm sure they probably have pals that need to be dumped.
* Added placeholders for the two pals that are on the bootleg version of Hyper Olympics and corrected the rom names to match their location on the board.

Subject: clock frequencies diff
Verified clocks on Rainbow Islands and Rambo 3 and Raiden 2. Reverted
sound OSC of Truxton 2 to 27mhz/8 since the original OST runs at this
speed. The pcb I measured the previous clock was 28mhz/8 and it's a
different pcb version from the common one. Since mame doesn't support
multiple OSC I prefer to use the 27mhz one.
Subject: _mul_32x32_hi() and _mulu_32x32_hi() patch
Hi/2.
I've attached patches to fix validation fail of '_mul_32x32_hi()' and
'_mulu_32x32_hi()' inline function when compiled GCC v3.3.5 with I686
optimization in according to advice of 'Vas Crabb'
Subject: Various little changes from the last month
I've been meaning to send these in for ages, but the day job has been
insane for a while now, so it's been hard to keep these up to date.
Firstly, I've fixed a few corner cases I've noticed in the 6840
emulation based on running the MPU4 test ROMs, and added the ability to
dynamically alter the external clock frequencies in game (since these
pins can be connected to other timing devices in a daisy chain, this may
well prove handy for speech chips and the like).
The 6850 core has also been changed to allow dynamic RX and TX clock
alteration, to at least try to remove a few of the MPU4 timing problems
(the ACIA clocks are triggered by the output pin of one of the 6840
timers, so the clock rate will vary according to what has been
programmed into the counter, rather than a fixed value).
MPU4 has been changed to document the Video board a bit better, and to
change a game name to match what is actually on the marquee. Other names
have changed, to better describe the program nature (AMLD versions are
legally speaking not SWPs, as there is no capacity for payout, so AMLD
SWP is an oxymoron).
Lastly, since I was smoketesting 6840ptm using cchasm anyway, I've added
some documentation of the Cosmic Chasm crystals, and merged the memory
maps.
Subject: [patch] Fix namcos2 multisession crash
Hi mamedev,
If you run a namcos2 game multi-session (say marvland), it may crash
due to an inappropriate use of auto_malloc. Fix attached.

Subject: Shadow Warriors inputs diff
Connected the buttons like they are wired on the original pcb (which is
jamma):
Button 1: Grab
Button 2: Attack
Button 3: Jump
Reviewed the following drivers:
alpha68k.c
actfancr.c
aeroboto.c
aerofgt.c
aliens.c
ambush.c
amidar.c
amspdwy.c
angelkds.c
appoooh.c
arabian.c
argus.c
arkanoid.c
Improved some DIP switches.
Added some DIP locations.
Replaced IPT_COINx with IPT_SERVICE1 where appropiate.
Simplified some control definitions.
to the sound and CPU interfaces. This is still a bit WIP, but works at
a fundamental level. Currently the only example of usage is in qix.c for
the MC6845 CRTC.
New module: mconfig.c/.h. Moved all machine_config and MDRV_* macros here,
out of driver.c/.h. Added MDRV macros for adding/removing/configuring
devices.
qix.c: Moved video part of machine driver to video/qix.c. Added MC6845
as a device in the machine driver. Removed explicit MC6845 initialization
from VIDEO_START in favor of simply retrieving the token from the device
interface code.
mc6845.c: Updated all callbacks to pass the mc6845_t * object. Updated
all drivers accordingly. Added a minimal device interface.
Deprecated the following constants because global constants that pretend
to document things but which are only guesses are dumb:
- DEFAULT_60HZ_VBLANK_DURATION
- DEFAULT_30HZ_VBLANK_DURATION
- DEFAULT_REAL_60HZ_VBLANK_DURATION
- DEFAULT_REAL_30HZ_VBLANK_DURATION
- DEFAULT_60HZ_3S_VBLANK_WATCHDOG
- DEFAULT_30HZ_3S_VBLANK_WATCHDOG
Updated all drivers to explicitly specify the equivalent bogus times.
Added comments for the "REAL" VBLANK durations to indicate that they are
not accurate.
Hi mamedev,
Here's my periodic batch of code cleanups. The usual batch of adding static/const plus some include fixes. In addition, I reverted some of the changes to build.mak from u1 which made some MSVC builds fail, and adjusted/optimized an m10.c gfx_layout. I also added some missing cores to cpuintrf.c, sndintrf.c and added some missing #if's to 5220intf.c.

Tried to "unified" the driver with m52 and m57 drivers (I still think that some things can be merged).
Don't forget to check SVN revisions 695 and 696 !
Since it's an SCSPx2 with ADPCM instead of FM it's already feature-complete except filter envelopes.
A bug in the ARM7 core causes incorrect pan/level values to be computed in e.g. the Naomi SOUND TEST menu (I've also been seeing this in DSF playback). This is not a defect in the AICA.
Please credit ElSemi, Deunan Knute, kingshriek, and myself.
moved decryption table setup to 'config' struct for the CPU.
added latest tables from robiza, making Risky Challenge playable, promoted it to working
told CPU core to not decrypt code after brkn instruction, enabling it again on iret, allowing me to remove several 'don't decrypt range' hacks in robiza's code.
updated all drivers accordingly.
currently the disassembly is a bit weird now, this will need looking at.
Tried to "unified" the drivers (I still think that some things can be merged).
Added src/includes/iremipt.h source file (same purpose as src/includes/taitoipt.h).
Fixed Dip Switches and inputs for 'alpha1v'. The game is now more playable to me but I left the GAME_NOT_WORKING flag as I think there are still some things to look at).
