IMPORTANT NOTE FOR OSD PORTERS: This build requires a pair of new
primitives in the OSD synchronization module, as well as some extended
functionality in the work item management. See below for details.
MAMETesters Bugs Fixed
cabal0119u2ora [David Haywood]
Fixed Cabal (joystick) submission from previous release.
Made a few improvements to dealem (well you can see the game now..)
Fixed broken SCSP from last update. [R. Belmont]
Changed parameters to read/write handlers from "address" to an
unmodified "original_address" parameter (having the passed parameter
being unmodified makes it easier to determine the original value while
debugging). [Nathan Woods]
Fixed colors in dynduke. [David Haywood]
Changed the following x86 instructions to read/write an entire word
rather than two separate bytes: [Philip Bennett]
- stosw (8086 only)
- rep stosw (8086 only)
Also tweaked handling of x86 WAIT instruction.
Several more opcode fixes for Risky Challenge. [robiza]
Cleaned up the include file usage in the code: [Atari Ace]
- Removed dead prototypes
- Added missing self-#includes
- Added missing source comments in mame/includes
- Migrated the few #include "driver.h" lines from driver header
files to source files (which is the common idiom).
- Eliminated #include "mame.h", "osdcore.h" et cetera from driver
files where #include "driver.h" would suffice.
- Removed unused srmp6.h and 9900stat.h
Added the rom loading for the various 5*XX roms, which are dumped but
not yet hooked up. [David Haywood]
Fixed error messages output from option.c. [Christophe Jaillet]
gstream driver update: [Pierpaolo Prazzoli]
- Changed to use a default nvram handler
- Checked the inputs
- Aligned the sprites
- Added some comments about oki banking
Major Sega Model 2 rewrite: [Ernesto Corvi]
- Decoupled the geometry engine code from the hardware rasterizer.
At this point, we could add emulation of the geometry DSPs for
the 2B and 2C models, and hook them directly to the rasterizer.
For the original and 2A models, an HLE geometry engine is provided
(currently in use for all models).
- Full Geometry Engine simulation, including support for specular,
multiple centers and dual polygon RAM.
- Support for all textured/transparent/checkered rendering modes.
- Improved texel/luma modulation
- Improved viewport clipping
- Improved z clipping
- Extensive notes and documentation.
- Greatly improved near Z-Clipping, still not perfect though.
- Improved perspective-correct texturing for large textures.
- Improved Z-Sorting
Changed Machine to machine in several places where feasible.
Added decryption of Jongkyo. [Nicola Salmoria]
The OSD layer is now required to supply to additional synchronization
primitives: osd_compare_exchange32() and osd_compare_exchange64().
These primitives should implement an atomic compare and exchange of
32-bit and 64-bit values, respectively. Added implementations of these
functions to the Windows OSD layer. [Aaron Giles]
Defined two new inline functions that are built on the new OSD
primitives: osd_compare_exchange_ptr(), which performs an atomic
compare/exchange on a pointer of the appropriate size, and
osd_sync_add() which atomically adds a value to a location in memory.
Changed implementation of OSD work queues that are created with the
WORK_QUEUE_FLAG_MULTI hint. Such queues now create n-1 threads, where
n in the number of logical processors in the system. This allows the
main thread to continue accomplishing things while other threads
process the work. If the main thread subsequently calls
osd_work_queue_wait(), it will then dynamically "jump in" and help
the other threads complete all the work items. [Aaron Giles]
Added new work item flag WORK_ITEM_FLAG_SHARED. When specified on a
work item that is queued to a work queue created with the
WORK_QUEUE_FLAG_MULTI hint, it means that all threads will be
dispatched to process the one work item, instead of the first thread
removing it. These "shared" work items are only considered complete
when all processing threads have returned. [Aaron Giles]
Added support for controlling multithreading behavior through an
environment variable OSDPROCESSORS. To override the default behavior,
set OSDPROCESSORS equal to the number of logical processors you wish
the OSD layer to pretend you have. [Aaron Giles]
Changed the 3dfx Voodoo emulation code to take advantage of the new
threading mechanisms above. It now creates a work queue with the
WORK_QUEUE_FLAG_MULTI flag set, and uses shared work items to spread
rasterization work across multiple processors. Note that this support
should be considered experimental; under some circumstances it is
known to deadlock. If you encounter problems, set OSDPROCESSORS to 1
to effectively produce the previous behavior. [Aaron Giles]
Added "top 20" dedicated rasterizers for all the Seattle games and
Gauntlet Legends/Dark Legacy. These improve rasterization performance
by another 10-20%. [Aaron Giles]
Fixed several more bugs in the 64-bit MIPS recompiler. It is now
capable of running the Seattle games and the 3D Gauntlets.
