* util: Further API cleanups: (#8661) Vas Crabb2021-10-051-3/+3
| | | | | * Turned `core_file` into an implementation of `random_read_write`. * Turned PNG errors into a standard error category. * Added a helper for generating what look like derived classes on-the-fly.
* harddisk.cpp: Allow specifying the desired block size for loose files / ↵ arbee2021-09-181-0/+2

* formats, osd, util: Started refactoring file I/O stuff. (#8456) Vas Crabb2021-08-221-4/+6
| | | | | | | | | Added more modern generic I/O interfaces with implementation backed by stdio, osd_file and core_file, replacing io_generic. Also replaced core_file's build-in zlib compression with a filter. unzip.cpp, un7z.cpp: Added option to supply abstract I/O interface rather than filename. Converted osd_file, core_file, archive_file, chd_file and device_image_interface to use std::error_condition rather than their own error enums. Allow mounting TI-99 RPK from inside archives.
* harddisk: Support non-CHD harddisk images in raw and 2MG format [R. Belmont] arbee2019-08-011-0/+3

* Better support for screen orientation/geometry: Vas Crabb2018-07-261-4/+4
| | | | | | | | | | | | | | | | | | | | | * Eliminates the need for the horizontal/vertical/LCD/SVG layout files * Screens can now have orientation and physical aspect ratio specified * RASTER/VECTOR defaults to 4:3, LCD/SVG defaults to square pixels at config time * System orientation is applied on top of screen orientation Automatically generated single-screen views and orientation flags in XML output now work correctly for systems with multiple screens in different geometries/orientations, e.g. housemnq, rocnms, stepstag, or netmerc. The "core rotation options" only interact with system orientation. Allowing multi-screen systems to work well with one monitor per emulated screen is a complex topic. System orientation also affects the GFX viewer while screen orientation doesn't. The orientation displayed in the system selection menu is from the system orientation. Let me know if I've broken any systems or use cases. Also, add save state support for std::array/C array nested to any depth.
* NOTICE (TYPE NAME CONSOLIDATION) Miodrag Milanovic2016-10-221-6/+6
| | | | | Use standard uint64_t, uint32_t, uint16_t or uint8_t instead of UINT64, UINT32, UINT16 or UINT8 also use standard int64_t, int32_t, int16_t or int8_t instead of INT64, INT32, INT16 or INT8

* Major CHD/chdman update. The CHD version number has been increased Aaron Giles2012-02-161-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
