Mame 0.120u2 update

[Robert]

Source

A new update to MAME 0.120 is now available on the Latest Release page. This update features an overhaul of the Mad Alien driver from Stefan Jokish, improved SCSI and I2C emulation from smf, a new 6850 ACIA implementation from Curt Coder, some progress on the Mortal Kombat 4 front, and some additional architecture-specific optimizations that are useful for 3D rasterization.

Source Changes

---------------------------

Rewrote ACIA6850 implementation. [Curt Coder]

 

Did a complete overhaul of the Mad Alien driver. [stefan Jokish]

- merged memory maps and added mirror addresses

- doubled sound chip frequency

- implemented IRQ acknowledge for the sound CPU

- added stub functions for missing discrete sounds

- re-implemented tilemaps (now the tunnel walls scroll into view)

- hooked up 6845 CRT controller

- made several fixes related to color handling

- cleaned up inputs and added dip switch locations

- raised main CPU speed (guesswork)

- added save state support

 

Repaired the IC24 timer behaviour to fix some of Deal 'Em's bugs, and also added inputs. [James Wallace]

 

Added save state support to skykid. [Mike Haaland]

 

Fixed tiny.mak based on new source reorg. [Tiago Pierezan Camargo]

 

Added support for CR-589 firmware to the System 573 driver. Made substantial changes to the SCSI support, making it require fewer hacks, and allowing one device to be derived from another. Also added save state support. [smf]

 

Added SCI support to M6803/HD63701. [Curt Coder]

 

Fixed several misnamed sound samples interfaces. [Atari Ace]

 

Switched model1 lookup functions to be index based rather than requiring a linear scan. [Atari Ace]

 

Added generic I2C bus memory support. Hooked up to the cubocd32 driver. [smf]

 

Cleaned up inline assembly support: [Aaron Giles]

* moved all inlinable functions into new module eminline.h

* defined a number of new inline functions, including:

- 32x32 -> 64 bit multiply

- fast approximate floating point reciprocal

* removed old inline definitions from osinline.h, osd_cpu.h, etc.

* eminline.h contains C implementations of everything

* new module eigccx86.h contains GCC-compatible x86/64 versions

* new module eigccppc.h contains GCC-compatible PowerPC versions

* eminline.h automatically detects GCC environments and includes appropriate file

* osinline.h now only used in non-GCC environments

* updated osd/windows/osinline.h to contain MSVC-compatible versions

 

Added NORM implementation to the TMS32031 core. [Aaron Giles]

 

Created new rgbutil module which consists of inline functions for common RGB manipulation. This module can be accelerated with SSE2 or other SIMD operations. By default, only 64-bit Intel builds make use

of SSE, since it can be assumed on those platforms. Reimplemented the namcos22 rasterizer in terms of these inline functions. Also updated the gaelco3d rasterizer to use this module for faster bilinear filtering. [Aaron Giles]

 

Made some progress on the Midway Zeus-based system. The 3d command stream is now parsed and the format is partially understood, enough to display some polygons but with incorrect textures in Mortal Kombat 4. [Aaron Giles]
