functionality in favor of alternate mechanisms. Errors are
now reported via an astring rather than via callbacks. Every
option must now specify a type (command, integer, float, string,
boolean, etc). Command behavior has changed so that only one
command is permitted. [Aaron Giles]
Changed fileio system to accept just a raw searchpath instead of
an options/option name combination. [Aaron Giles]
Created emu_options class dervied from core_options which wraps
core emulator options. Added mechanisms to cleanly change the
system name and add/remove system-specific options, versus the
old way using callbacks. Also added read accessors for all the
options, to ensure consistency in how parameters are handled.
Changed most core systems to access emu_options instead of
core_options. Also changed machine->options() to return emu_options.
[Aaron Giles]
Created cli_options class derived from emu_options which adds the
command-line specific options. Updated clifront code to leverage
the new class and the new core behaviors. cli_execute() now accepts
a cli_options object when called. [Aaron Giles]
Updated both SDL and Windows to have their own options classes,
derived from cli_options, which add the OSD-specific options on
top of everything else. Added accessors for all the options so
that queries are strongly typed and simplified. [Aaron Giles]
Out of whatsnew: I've surely screwed up some stuff, though I have
smoke tested a bunch of things. Let me know if you hit anything odd.
Also I know this change will impact the WINUI stuff, please let me
know if there are issues. All the functionality necessary should
still be present. If it's not obvious, please talk to me before
adding stuff to the core_options class.
and manages a collection of hashes, and can be built from an internal
format string which is stored with each ROM. All core instances are
cleaned up to use the new interfaces, but it's likely that hashfile
code in MESS will need an update.
Also compacted the form of the hash strings used for ROMs, and fixed
verification/hashing of non-ZIPped files.
to pass a core_options object to the constructor, along with
a search path. This required pushing either a running_machine
or a core_options through some code that wasn't previously
ready to handle it. emu_files can be reused over multiple
open/close sessions, and a lot of core code cleaned up
nicely as things were converted to them.
Also created a file_enumerator class for iterating over files
in a searchpath. This replaces the old mame_openpath functions.
Changed machine->options() to return a reference.
Removed public nvram_open() and fixed jchan/kaneko16 to
stop directly saving NVRAM.
Removed most of the mame_options() calls; this will soon go
away entirely, so don't add any more.
Added core_options to device_validity_check() so they can be
used to validate things.
- Default for writeconfig is now 0 for MESS since it is not needed anymore
- Fixed handling of mounted devices on hard reset
- Unified some emuopts code, and removed ifdefs
- Created new central header "emu.h"; this should be included
by pretty much any driver or device as the first include. This
file in turn includes pretty much everything a driver or device
will need, minus any other devices it references. Note that
emu.h should *never* be included by another header file.
- Updated all files in the core (src/emu) to use emu.h.
- Removed a ton of redundant and poorly-tracked header includes
from within other header files.
- Temporarily changed driver.h to map to emu.h until we update
files outside of the core.
Added class wrapper around tagmap so it can be directly included
and accessed within objects that need it. Updated all users to
embed tagmap objects and changed them to call through the class.
Added nicer functions for finding devices, ports, and regions in
a machine:
machine->device("tag") -- return the named device, or NULL
machine->port("tag") -- return the named port, or NULL
machine->region("tag"[, &length[, &flags]]) -- return the
named region and optionally its length and flags
Made the device tag an astring. This required touching a lot of
code that printed the device to explicitly fetch the C-string
from it. (Thank you gcc for flagging that issue!)
useable as a stack object. Also designed the interfaces to allow
for chaining operations. And added a casting operator to const
char * for seamless use in most functions that take plain old C
strings.
Changed all uses of astring to use the object directly on the
stack or embedded in objects instead of explicitly allocating
and deallocating it. Removed a lot of annoying memory management
code as a result.
Changed interfaces that accepted/returned an astring * to
use an astring & instead.
Removed auto_alloc_astring(machine). Use
auto_alloc(machine, astring) instead.
osd_free(). They take the same parameters as malloc() and free().
Renamed mamecore.h -> emucore.h.
New C++-aware memory manager, implemented in emualloc.*. This is a
simple manager that allows you to add any type of object to a
resource pool. Most commonly, allocated objects are added, and so
a set of allocation macros is provided to allow you to manage
objects in a particular pool:
pool_alloc(p, t) = allocate object of type 't' and add to pool 'p'
pool_alloc_clear(p, t) = same as above, but clear the memory first
pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type
't' and add to pool 'p'
pool_alloc_array_clear(p, t, c) = same, but with clearing
pool_free(p, v) = free object 'v' and remove it from the pool
Note that pool_alloc[_clear] is roughly equivalent to "new t" and
pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also
note that pool_free works for single objects and arrays.
There is a single global_resource_pool defined which should be used
for any global allocations. It has equivalent macros to the pool_*
macros above that automatically target the global pool.
In addition, the memory module defines global new/delete overrides
that access file and line number parameters so that allocations can
be tracked. Currently this tracking is only done if MAME_DEBUG is
enabled. In debug builds, any unfreed memory will be printed at
the end of the session.
emualloc.h also has #defines to disable malloc/free/realloc/calloc.
Since emualloc.h is included by emucore.h, this means pretty much
all code within the emulator is forced to use the new allocators.
Although straight new/delete do work, their use is discouraged, as
any allocations made with them will not be tracked.
Changed the familar auto_alloc_* macros to map to the resource pool
model described above. The running_machine is now a class and contains
a resource pool which is automatically destructed upon deletion. If
you are a driver writer, all your allocations should be done with
auto_alloc_*.
Changed all drivers and files in the core using malloc/realloc or the
old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros
instead, or the global_alloc_* macros if necessary.
Added simple C++ wrappers for astring and bitmap_t, as these need
proper constructors/destructors to be used for auto_alloc_astring and
auto_alloc_bitmap.
Removed references to the winalloc prefix file. Most of its
functionality has moved into the core, save for the guard page
allocations, which are now implemented in osd_alloc and osd_free.
and then keep searching the searchpath for the next valid file. Did some
internal rearranging in fileio.c to make this work.
Changed cheat search so that it loads *all* cheat files in all search
paths. Note that it is easy to end up with duplicate entries this way.
Some currently disabled code is present which filters out duplicates,
but the logic for doing this is quite unclear with the presence of
text-only cheats, which is why the code is disabled for now.
* Added Crosshair Options menu
- ability to individually enable/disable crosshairs
- ability for them to automatically disappear after a set amount of time
- ability to select crosshair graphic
- all settings are saved in the cfg file
* Removed F1 toggle for crosshairs
* Added new command option -crsshairpath
- store all selectable graphics here
- see config.txt for further info
OSD NOTE: render_load_png() has been changed to no longer force usage of the artwork directory.
Do a search for "render_load_png(" and replace with "render_load_png(OPTION_ARTPATH, " if needed.
----------------------------
F1 is now free to use for something new. I was thinking it would be perfect for a context sensitive help file. Each menu item could have a help tag, that it would look up and display info from an HTML file.
Updated the fcompress APIs to allow for specifying a compression level.
Removed the concept of state saving tags, which was a hack to get save states
to work with multiple CPU cores. Simplified the state saving system as a
result, performing the operation in a single pass and without allocating
a full blob of memory. Also enabled minimal compression.
To fix this, I had to break old INP files. While I was in there,
I added corefile support for compressing/decompressing data on
the fly, and enabled it for INPs, meaning the newer format INPs
are output and processed compressed.
files. Removed old option 'cheat_file'.
Updated xmlfile.c to specify the line number for each node, for more
accurate error reporting.
Removed old cheat.c/.h and replaced them with code that will read and
write the new XML-based cheat format using the new cheatpath option
(cheats still need to be enabled in order to load at all). Note that
the cheats are not implemented yet, but they are fully parsed. To test
saving, whenever a cheat file is successfully loaded, it is immediately
written back out as 'output.xml' to the cheat directory for validation.
to write RGB bitmaps. Unfortunately, the only option is fully
uncompressed, which means the resulting AVIs are *HUGE* and
may not play correctly in realtime due to high data rate. The
intention is that these uncompressed AVIs are post-processed
by other utilities to compress the video and produce a
realtime playable result.
Added new command-line option -aviwrite which works just like
-mngwrite, except it produces AVIs and streams sound to them.
Updated documentation accordingly.
Shift+F12 still produces MNGs for now, though this might change
in the future.
Modified fileio.c to retain the full pathname to the file so
that it can be queried while the file is open.
- removed years from copyright notices
- removed redundant (c) from copyright notices
- updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
This is an updated version of my earlier ATTR_PRINTF patch. It was
reviewed by Atari Ace to use ATTR_PRINTF properly and fixes even more
format errors. I also reviewed the whole source again and it is now
used in all possible places.
