- Add MIDI in and out ports as image device types
- Add OSD calls to check for and read MIDI input
- Add MIDI in image device which reads input and converts it to a serial bitstream
nw section:
Note that the MIDI In device uses the new image device override to prevent the core from attempting to fopen() the "file" name and instead it handles open/close itself in call_load/call_unload. This allows greater flexibilty than the hack used for sockets/ptys/named pipes where the OSD file layer has to know about them.
- drawd3d.c: Move default_texture creation into device_create_resources. Should
fix intermittent crashes when alt-tabbing back to a full-screen
instance of MAME. [MooglyGuy]
Tested on: Linux x64, Mac OS X 10.8, Windows 8 x64 w/latest toolchain for both OSD=windows and OSD=sdl. MIDI should auto-disable on other OSes (*BSD) but there may be problems. Works fine on Linux when set to use the system's copy of the library as well, which many distros prefer.
hlsl: Added bounds-checking on presets. [MooglyGuy]
hlsl: Cleaned up render target management. May provide better behavior in games
that use multiple resolutions, e.g. tekken3 and stv. [MooglyGuy]
intended differences from previous behavior. For drivers,
the main change is that input_port_read() no longer exists.
Instead, the port must be fetched from the appropriate device,
and then read() is called.
For member functions, this is actually simpler/cleaner:
value = ioport("tag")->read()
For legacy functions which have a driver_data state, it goes:
value = state->ioport("tag")->read()
For other legacy functions, they need to fetch the root device:
value = machine.root_device().ioport("tag")->read()
The other big change for drivers is that IPT_VBLANK is gone.
Instead, it has been replaced by a device line callback on the
screen device. There's a new macro PORT_VBLANK("tag") which
automatically points things to the right spot.
Here's a set of imperfect search & replace strings to convert
the input_port_read calls and fix up IPT_VBLANK:
input_port_read( *\( *)(machine\(\)) *, *([^)]+ *\))
ioport\1\3->read\(\)
input_port_read( *\( *)(.*machine[()]*) *, *([^)]+ *\))
\2\.root_device\(\)\.ioport\1\3->read\(\)
(state = .*driver_data[^}]+)space->machine\(\)\.root_device\(\)\.
\1state->
(state = .*driver_data[^}]+)device->machine\(\)\.root_device\(\)\.
\1state->
input_port_read_safe( *\( *)(machine\(\)) *, *([^,]+), *([^)]+\))
ioport\1\3->read_safe\(\4\)
IPT_VBLANK( *\))
IPT_CUSTOM\1 PORT_VBLANK("screen")
sound devices for each of the Midway 8-bit sound
boards. This will also aid in eventually hooking them
up to pinballs.
Enhanced the mixer interface support to allow for
more than one output line. To use this you need to
use the MCFG_MIXER_ROUTE macro instead of
MCFG_SOUND_ROUTE so that the mixer output index can
be specified. See midway_ssio_device for an example.
from 4 to 5. This means any diff CHDs will no longer work. If you
absolutely need to keep the data for any existing ones you have,
find both the diff CHD and the original CHD for the game in question
and upgrade using these commands:
rename diff\game.dif diff\game-old.dif
chdman copy -i diff\game-old.dif -ip roms\game.chd -o diff\game.dif -op roms\game.chd -c none
Specifics regarding this change:
Defined a new CHD version 5. New features/behaviors of this version:
- support for up to 4 codecs; each block can use 1 of the 4
- new LZMA codec, which tends to do better than zlib overall
- new FLAC codec, primarily used for CDs (but can be applied anywhere)
- upgraded AVHuff codec now uses FLAC for encoding audio
- new Huffman codec, used to catch more nearly-uncompressable blocks
- compressed CHDs now use a compressed map for significant savings
- CHDs now are aware of a "unit" size; each hunk holds 1 or more units
(in general units map to sectors for hard disks/CDs)
- diff'ing against a parent now diffs at the unit level, greatly
improving compression
Rewrote and modernized chd.c. CHD versions prior to 3 are unsupported,
and version 3/4 CHDs are only supported for reading. Creating a new
CHD now leaves the file open. Added methods to read and write at the
unit and byte level, removing the need to handle this manually. Added
metadata access methods that pass astrings and dynamic_buffers to
simplify the interfaces. A companion class chd_compressor now
implements full multithreaded compression, analyzing and compressing
multiple hunks independently in parallel. Split the codec
implementations out into a separate file chdcodec.*
Updated harddisk.c and cdrom.c to rely on the caching/byte-level read/
write capabilities of the chd_file class. cdrom.c (and chdman) now also
pad CDs to 4-frame boundaries instead of hunk boundaries, ensuring that
the same SHA1 hashes are produced regardless of the hunk size.
Rewrote chdman.exe entirely, switching from positional parameters to
proper options. Use "chdman help" to get a list of commands, and
"chdman help <command>" to get help for any particular command. Many
redundant commands were removed now that additional flexibility is
available. Some basic mappings:
Old: chdman -createblankhd <out.chd> <cyls> <heads> <secs>
New: chdman createhd -o <out.chd> -chs <cyls>,<heads>,<secs>
Old: chdman -createuncomphd <in.raw> <out.chd> ....
New: chdman createhd -i <in.raw> -o <out.chd> -c none ....
Old: chdman -verifyfix <in.chd>
New: chdman verify -i <in.chd> -f
Old: chdman -merge <parent.chd> <diff.chd> <out.chd>
New: chdman copy -i <diff.chd> -ip <parent.chd> -o <out.chd>
Old: chdman -diff <parent.chd> <compare.chd> <diff.chd>
New: chdman copy -i <compare.chd> -o <diff.chd> -op <parent.chd>
Old: chdman -update <in.chd> <out.chd>
New: chdman copy -i <in.chd> -o <out.chd>
Added new core file coretmpl.h to hold core template classes. For now
just one class, dynamic_array<> is defined, which acts like an array
of a given object but which can be appended to and/or resized. Also
defines dynamic_buffer as dynamic_array<UINT8> for holding an
arbitrary buffer of bytes. Expect to see these used a lot.
Added new core helper hashing.c/.h which defines classes for each of
the common hashing methods and creator classes to wrap the
computation of these hashes. A future work item is to reimplement
the core emulator hashing code using these.
Split bit buffer helpers out into C++ classes and into their own
public header in bitstream.h.
Updated huffman.c/.h to C++, and changed the interface to make it
more flexible to use in nonstandard ways. Also added huffman compression
of the static tree for slightly better compression rates.
Created flac.c/.h as simplified C++ wrappers around the FLAC interface.
A future work item is to convert the samples sound device to a modern
device and leverage this for reading FLAC files.
Renamed avcomp.* to avhuff.*, updated to C++, and added support for
FLAC as the audio encoding mechanism. The old huffman audio is still
supported for decode only.
Added a variant of core_fload that loads to a dynamic_buffer.
Tweaked winwork.c a bit to not limit the maximum number of processors
unless the work queue was created with the WORK_QUEUE_FLAG_HIGH_FREQ
option. Further adjustments here are likely going to be necessary.
Fixed bug in aviio.c which caused errors when reading some AVI files.
To test it, I used my Logitech Trackball (normally a mouse) and configured it as a joystick.
Prerequisites:
- Locate your linux input device for the trackball. In my case that's /dev/input/event3
- "sudo chmod a+r /dev/input/event3"
- "export SDL_JOYSTICK_DEVICE=/dev/input/event3"
This forces sdl to recognize the trackball as a input device.
-mame64 missile -nomouse -w
Configure the trackball axis. Make sure the mouse pointer is outside the window and window still has keyboard focus - most modern window manager should support this.
Quit and restart with
-mame64 missile -mouse -now
to hide the mouse. Voila. Works.
- The SDL team has moved from 1.3 to 2.0. At the same time, changes were made to allow SDL1.2 and SDL2.0 to coexist. All SDL2.0 include files are now in /usr/include/SDL2.
- Added sdlinc.h to avoid having tons of #ifdef .. #include in the code.
- Scalemode is no longer a per-window setting
- Fixed a bug in YUV rendering.
- Use SDL_GetClipboard (SDL2.0)
- Updated README_SDL20.txt
Currently, SDL 2.0 is only supported on *nix. Volunteers welcome.
and paths consistently for devices, I/O ports, memory
regions, memory banks, and memory shares. [Aaron Giles]
NOTE: there are likely regressions lurking here, mostly
due to devices not being properly found. I have temporarily
added more logging to -verbose to help understand what's
going on. Please let me know ASAP if anything that is being
actively worked on got broken.
As before, the driver device is the root device and all
other devices are owned by it. Previously all devices
were kept in a single master list, and the hierarchy was
purely logical. With this change, each device owns its
own list of subdevices, and the hierarchy is explicitly
manifest. This means when a device is removed, all of its
subdevices are automatically removed as well.
A side effect of this is that walking the device list is
no longer simple. To address this, a new set of iterator
classes is provided, which walks the device tree in a depth
first manner. There is a general device_iterator class for
walking all devices, plus templates for a device_type_iterator
and a device_interface_iterator which are used to build
iterators for identifying only devices of a given type or
with a given interface. Typedefs for commonly-used cases
(e.g., screen_device_iterator, memory_interface_iterator)
are provided. Iterators can also provide counts, and can
perform indexed lookups.
All device name lookups are now done relative to another
device. The maching_config and running_machine classes now
have a root_device() method to get the root of the hierarchy.
The existing machine->device("name") is now equivalent to
machine->root_device().subdevice("name").
A proper and normalized device path structure is now
supported. Device names that start with a colon are
treated as absolute paths from the root device. Device
names can also use a caret (^) to refer to the owning
device. Querying the device's tag() returns the device's
full path from the root. A new method basetag() returns
just the final tag.
The new pathing system is built on top of the
device_t::subtag() method, so anyone using that will
automatically support the new pathing rules. Each device
has its own internal map to cache successful lookups so
that subsequent lookups should be very fast.
Updated every place I could find that referenced devices,
memory regions, I/O ports, memory banks and memory shares
to leverage subtag/subdevice (or siblingtag/siblingdevice
which are built on top).
Removed the device_list class, as it doesn't apply any
more. Moved some of its methods into running_machine
instead.
Simplified the device callback system since the new
pathing can describe all of the special-case devices that
were previously handled manually.
Changed the core output function callbacks to be delegates.
Completely rewrote the validity checking mechanism. The
validity checker is now a proper C++ class, and temporarily
takes over the error and warning outputs. All errors and
warnings are collected during a session, and then output in
a consistent manner, with an explicit driver and source file
listed for each one, as well as additional device and/or
I/O port contexts where appropriate. Validity checkers
should no longer explicitly output this information, just
the error, assuming that the context is provided.
Rewrote the software_list_device as a modern device, getting
rid of the software_list_config abstraction and simplifying
things.
Changed the way FLAC compiles so that it works like other
external libraries, and also compiles successfully for MSVC
builds.
almost certainly some regressions lurking. Let me know if
something seems busted.
Bitmaps are now strongly typed based on format. bitmap_t still
exists as an abstract base class, but it is almost never used.
Instead, format-specific bitmap classes are provided:
bitmap_ind8 == 8bpp indexed
bitmap_ind16 == 16bpp indexed
bitmap_ind32 == 32bpp indexed
bitmap_ind64 == 64bpp indexed
bitmap_rgb32 == 32bpp RGB
bitmap_argb32 == 32bpp ARGB
bitmap_yuy16 == 16bpp YUY
For each format, a generic pix() method is provided which
references pixels of the correct type. The old pix8/pix16/pix32/
pix64 methods still exist in the short term, but the only one
available is the one that matches the bitmap's pixel size. Note
also that the old RGB15 format bitmaps are no longer supported
at all.
Converted model1, megadriv, and stv drivers away from the RGB15
format bitmaps.
New auto_bitmap_<type>_alloc() macros are provided for allocating
the appropriate type of bitmap.
Screen update functions now must specify the correct bitmap type
as their input parameters. For static update functions the
SCREEN_UPDATE macro is now replaced with SCREEN_UPDATE_RGB32 and
SCREEN_UPDATE_IND16 macros. All existing drivers have been
updated to use the correct macros.
Screen update functions are now required for all screens; there
is no longer any default behavior of copying a "default" bitmap
to the screen (in fact the default bitmap has been deprecated).
Use one of the following to specify your screen_update callback:
MCFG_SCREEN_UPDATE_STATIC(name) - static functions
MCFG_SCREEN_UPDATE_DRIVER(class, func) - driver members
MCFG_SCREEN_UPDATE_DEVICE(tag, class, func) - device members
Because the target bitmap format can now be deduced from the
screen update function itself, the MCFG_SCREEN_FORMAT macro is
no longer necessary, and has been removed. If you specify a
screen update callback that takes a bitmap_ind16, then the screen
will be configured to use a 16bpp indexed bitmap, and if you
specify a callback that takes a bitmap_rgb32, then a 32bpp RGB
bitmap will be provided.
Extended the bitmap classes to support wrapping a subregion of
another bitmap, and cleaner allocation/resetting. The preferred
use of bitmaps now is to define them directly in drivers/devices
and use allocate() or wrap() to set them up, rather than
allocating them via auto_bitmap_*_alloc().
Several common devices needed overhauls or changes as a result
of the above changes:
* Reorganized the laserdisc base driver and all the laserdisc
drivers as modern C++ devices, cleaning the code up
considerably. Merged ldsound device into the laserdsc
device since modern devices are flexible enough to handle
it.
* Reorganized the v9938 device as a modern C++ device. Removed
v9938mod.c in favor of template functions in v9938.c directly.
* Added independent ind16 and rgb32 callbacks for TMS340x0 devices.
* All video devices are now hard-coded to either ind16 or rgb32
bitmaps. The most notable is the mc6845 which is rgb32, and
required changes to a number of consumers.
* Added screen_update methods to most video devices so they can be
directly called via MCFG_SCREEN_UPDATE_DEVICE instead of creating
tons of stub functions.
parameters for the global SCREEN_UPDATE callback match the parameters
for the driver_device version. Added allocate() and deallocate()
methods to bitmap_t to permit cleaner handling of bitmaps in drivers
and modern devices. [Aaron Giles]
macros with bitmap->pix* functions, and moved bitmap_fill() to bitmap->fill()
among other similar changes. Bitmap fields now only available via accessors.
Replaced sect_rect with &= and union_rect with |= operators for rectangle
classes. Some general cleanup as a result of these changes. [Aaron Giles]
