* Numerous jedutil tool improvements. [Kevin Eshbach] Scott Stone2012-09-051-27/+1450
| | | | | | | | | | | | | | Made some modifications to the jedutil tool to allow the viewing of simple combinatorial jeds (adding support for registered and gals in the future) by taking a jed file and printing out human-readable equations. Changed the command line options of the jedutil tool to know take an initial argument to specify what the tool should do. For example to convert a jed to bin the command is now: jedutil –convert <source.jed> <dest.bin> jedutil –convert <source.bin> <dest.jed> To view a jed file with human-readable equations the command is jedutil –view <source.jed> <pal type> Added a simple regression test for the tool that just verifies that the currently known pals have the row and column fuse location mapped correctly and at the moment this tool runs under windows only. Under the directory src/regtests/jedutil there is a Windows Script File with the name jedtest.wsf that if run from the command line with the command “cscript jedtest.wsf” will verify that a dump of the jeds in src/regtests/jedutil/jeds matches the good dumps in src/regtests/jedutil/baseline. Reference jed files created using the tool eqn2jed which is included with Opal Jr and these files are in src/regtests/jedutil/eqns.

[David Haywood] Added CD compressor template which separates subcode data from sector data, removes redundant ECC data prior to compression, and uses separate compressors for each part. Defined LZMA and ZLib CD compressors based on this and made them the default for CDs. [Aaron Giles] (Sadly couldn't wrap the FLAC compressor here because it would have produced incompatible output with previous versions.)

* When copying CHDs, preserve the flag that indicates whether the metadata Aaron Giles2012-03-061-2/+2

[David Haywood] Re-did the non-CD FLAC codec to be "smart" in that it can choose either big-endian or little-endian on the fly and uses the best one.

* Fail initializing the CD-FLAC codec if the hunk size is not CD-compatible. Aaron Giles2012-02-171-491/+510
| | | | | | Centralize detection of existing output files. Add detection (require --force) for extracted files as well. Move checks outside of try/catch so that the files are not subsequently deleted.
* Added new CHD codec: CD-FLAC which knows how to shuffle CD data Aaron Giles2012-02-171-2/+2
| | | | | | | to more optimally use FLAC. Updated flac wrapper to implement a tell callback so FLAC can tell us how much we've decoded. Updated chdman to use CD-FLAC codec in preference over the existing codecs for CDs by default. Credit Haze for the idea.
* Major CHD/chdman update. The CHD version number has been increased Aaron Giles2012-02-162-3021/+2234
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Added FLAC (lossless audio) codec support plus experimental hooks in samples ↵ R. Belmont2012-01-222-8/+17

* Major bitmap-related changes throughout the system. There are Aaron Giles2012-01-124-482/+447
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
