Source Changes
--------------
Hooked up default NVRAM and fixed sample rom loading order in
Championship Bowling [David Haywood]

snes.c: greatly simplified tile drawing routines, fixed a couple of
small bugs in mosaic support, reworked debug functions to be detected
properly in all games [Fabio Priuli]

and DMA transfers (not all addresses can be accessed) [Fabio Priuli]

snes.c: enabled PPU->CPU hdma transfer and moved hdma variables to
snes_state [Fabio Priuli]

snes.c: updated HDMA to init/update according to Anomie's docs
[Fabio Priuli]

namcos23: First extremely rough 3D hookup [O. Galibert]

Changed the killing blade parent to the pgm bios. [smf]

namcos23: Add some lighting. [O. Galibert, Naibo]

namcos23: hooked up tilemap scroll, improved raster IRQ [R. Belmont]

snes.c: enforced abus validity check on dma reads, fixed possible tile
and vram out of bounds bugs [Fabio Priuli]

Replaced Stocker dump with a good set [Kevin Eshbach]

Hooked up default NVRAM for Golly Ghost / Bubble Trouble
[David Haywood]

namcos23: Add 3D model scaling [O. Galibert]

Heavily improved the slot 72 - poker game, it's now known to be
actually Poker Monarch. [Angelo Salese]

    frame
* FREM instruction supported
* Better disassembly of FPU instructions

WRAM [Fabio Priuli]

namcos23: c361 fixes and address auto-increment [O. Galibert]

further snes.c wip: [Fabio Priuli]

    MUL/DIV tests)
* Implemented very preliminary (and currently broken) SPC7110 RTC
    emulation
* Updated DSP2 handlers to better reflect Overload's docs (problem
    and fix actually found by byuu)
- Updated add-on chips handlers to reflect byuu's findings

snes.c wip: fixed reserved memory address read not returning open_bus;
fixed a few add-on chip reads not returning open_bus [Fabio Priuli]

Made input_device pointers non-volatile. Since we return pointers to
them in response to input_device_add(), ensure that the pointers don't
change after subsequent adds. [Aaron Giles]

snes.c: fixed a SRAM size problem and moved PPU registers handling to
video/snes.c [Fabio Priuli]

* machine\midwunit.c:  Hooked up outputs for Revolution X.
* machine\midyunit.c:  Hooked up outputs for Terminator 2.
* drivers\seta.c:  Hooked up outputs for Zombie Raid.

i386/NEC disassembler updates: [Alex Jackson]
* Made "MOV AL, offset" etc (opcodes A0-A3) properly indicate a
    segment override prefix.
* Corrected the disassembly of various NEC-only instructions (mainly
    V25/V35-only instructions)
* Changed CPUINFO_INT_MAX_INSTRUCTION_BYTES on i86 and NEC from 15 to
    8.

Added correct ROMs to 'Dragon's Lair (Italian)' (dlital) [f205v]

Improvements to supdrapo.c driver [Roberto Fresca]
* Reworked inputs to match the standard poker inputs names/layout.

    and/or an external device.
* Added machine start & reset.
* All clocks pre defined.
* Added ay8910 interfase as a preliminary attempt to analyze the
    unknown port writes when these ports are set as input.

    or Better, Two Pair). Deal Speed (Slow, Fast). Aces Type (Normal
    Aces, Number 1). Cards Deck Type (english cards, french cards).

* Added NVRAM support.
* Reorganized and cleaned-up the driver.

[Angelo Salese]

Disabled unused variables and code based on cppcheck and VS2008 Code
Analysis [Oliver Stoneberg]

and corrected the rom names for Rail Chase [ANY]

Added gprof support to the makefile. [Bryan Ischo]

Added a check for the OPTION_READCONFIG option before executing
the code which would attempt to incorporate configuration file
settings into the current configuration, because if OPTION_READCONFIG
is set to false, then there is no reason to even try to do this as
every single configuration file will be ignored (because config files
have been turned off by OPTION_READCONFIG). [Bryan Ischo]

Fixed small memory leak in mame.c. [Bryan Ischo]
