- Color generation from schematics (resistor mixer) for
radarscp, dkong, dkongjr and dkong3

Added new components to the discrete sound system: [couriersud]
- Added a "inverter oscillator" component. This can also be used as
a raw sine generator - needed by radarscp.
- Added a "integration circuit" based on transistor and RC
- Added a "modulated RC discharge" component.

Removed unused return value from VIDEO_START callbacks.
[Zsolt Vasvari]

Fixed Space Firebird so that the sprites are opaque with respect to
each other and bullets, but transparent with respect to the star
field. [Zsolt Vasvari]

Fixed subtle behavior in handling of PIA port A. This allows for the
removal of hacks in the Qix driver and the Williams driver.
[Zsolt Vasvari]

Cleaned up the tilemap get_info callbacks: [Atari Ace]
* regularized and clean up the existing callbacks
* changed some callbacks to use int tile_index as the parameter
so that all callbacks use consistent naming
* folded some direct uses of tile_info.flags into calls to
* changed the Konami drivers to manipulate the tile_info global only
within the tile_get_info callbacks
* replaced all the callback declarations with TILE_GET_INFO()
* changed the interface to pass tile_info as a parameter and made
tile_info a static variable only accessible inside tilemap.c.

Significant changes to the berzerk driver: [Zsolt Vasvari]
- Video timings, memory map and interrupt system implemented from
- Hooked up colors according to the schematics as well. The colors
changed significantly. For example the yellow robots are now
more like a mustard color.

on a reset. Also fixed cycle timing and removed obsolete code from
the core. [Ernesto Corvi, Zsolt Vasvari]

Cleaned up vec_mult implementation. [Nathan Woods]

Improved toratora driver: [Zsolt Vasvari]
- added SN76477 from the schematics, but it sounds terrible; no doubt
the schematics are incorrect in many places
- updated to the recent PIA changes

Fixed input.c to use osd_ticks() instead of clock(). [Nathan Woods]

Fixed bit calculation in 6526cia.c which broke joysticks in the C64
driver in MESS. [Pete Rittwage]

Improvements to the rd2tank driver: [Zsolt Vasvari]
- fixed colors, based on the Red Tank flyer
- added AY8910's, sounds fine, but how exactly they are hooked up
to the PIA is not fully understood.

configuration and video rendering. Updated the Qix and Spiders driver
to use the new functionality. Added notifications for when the
display enable pin changes in order to drive blanking signals.
[Zsolt Vasvari]

New 74123 timer emulator. It supports different ways a 74123 can be
hooked up that affect the timing period. The old implementation was
incorrect in lots of respects. [Zsolt Vasvari]

Removed the addressing order parameter from pia_config() and replaced
it with dedicated write and read handlers. [Zsolt Vasvari]

at the driver level. This allows us to properly describe the screen
width/height and blanking in the driver independent of specifying a
good default size to crop the image to. [Aaron Giles]

Added border support to the Astrocade driver. Extended the starfield
generation out into it. Extended the blanking region out farther to
match information from the flyers and set the default scale/offset
of the games to crop appropriately. [Aaron Giles]

Identified a couple of new opcodes in the Irem V30 CPU which improves
matchit2. [Pierpaolo Prazzoli]

Significantly cleaned up the Spiders driver. [Zsolt Vasvari]

Changed memory system behavior so that masks can be specified
independently of mirrors. By default if the mask is 0 and a mirror
is present, the mask is implicitly ~mirror, just as before. But if a
mask is specified, it is not limited to the non-mirrored bits. This
allows you to independently control the mapping versus what is
returned to the read/write handler. [Aaron Giles]

Rewrote Astrocade driver: [Aaron Giles]
- fully implemented all function generator modes
- implemented pattern board according to schematics, including timing
- fixed interrupt handling
- added crosshairs to SeaWolf II

emulation and internal layout

Fixed sound in Inferno after all these years. Sadly, it required a
hack. [Aaron Giles]

Added correct video timings for the Williams games. [Aaron Giles]

Added support for misaligned PIXBLT operations in the TMS34010 core.
The code still needs cleanup but improves the new JPM driver.

Wow discrete sound in Donkey Kong. Man, along with the CPS3 work being done right now, MAMEDev is on a roll. Every time I think "ain't gonna see *that* for 20 years" they keep proving me wrong. Thank god for that.

Me too. I hope the colors are finally fixed in Gorf.

Maybe I'll actually have to check out one of the MacMAME alternatives now.

Nice little update!

So I've got a little question... I just picked up a shiny new MacBook Pro, Intel Inside, and I'm wondering what my MacMAME options are.

Hmmm... answering my own question (Is that akin to talking to yourself) It looks like MAMEOSX-0.114 is the best bet.
