Game_Music_Emu Change Log
|
||||
-------------------------
|
||||
|
||||
Game_Music_Emu 0.6.0
|
||||
--------------------
|
||||
|
||||
- Note: A 0.5.6 release was referenced but never tagged or packaged.
|
||||
|
||||
- SPC improvements:
|
||||
- Switched to newer snes_spc 0.9.0 for SPC emulation. Uses fast DSP.
|
||||
- Fixed Spc_Emu::gain().
|
||||
- Fixed support for files <0x10200 bytes.
|
||||
|
||||
- Other bugfixes:
|
||||
- Fixed a couple of GBS bugs, one involving access of memory after
|
||||
realloc.
|
||||
- Blip_Buffer works on systems where 'double' is a single-precision
|
||||
floating-point type.
|
||||
- Fix uninitialized buffer size in dual_resampler.
|
||||
- Compilation warnings squashed out as of clang 3.3-pre and gcc 4.7.2.
|
||||
|
||||
- API changes/additions:
|
||||
- Removed documentation of C++ interface, as the C interface in gme.h is
|
||||
the only supported one.
|
||||
- Added gme_enable_accuracy() for enabling more accurate sound emulation
|
||||
options (currently affects SPC only).
|
||||
|
||||
- Build system improvements:
|
||||
- Add pkg_config support.
|
||||
- Fix build on case-insensitive systems.
|
||||
- Allow for install on Cygwin.
|
||||
- Fix install on multilib systems, such as many 64-bit distros (CMake must
|
||||
be able to figure out your system's libsuffix, if any).
|
||||
- C++ implementation symbols are not leaked into the resultant library
|
||||
file (requires symbol visibility support).
|
||||
|
||||
- Sample player improvements:
|
||||
- Can toggle fast/accurate emulation (with the 'A' key).
|
||||
|
||||
Game_Music_Emu 0.5.5
|
||||
--------------------
|
||||
- CMake build support has been added. You can build Game_Music_Emu as
|
||||
a shared library and install it so that you do not have to include your
|
||||
own copy if you know libgme will be present on your target system.
|
||||
Requires CMake 2.6 or higher.
|
||||
|
||||
|
||||
Game_Music_Emu 0.5.2
|
||||
--------------------
|
||||
- *TONS* of changes and improvements. You should re-read the new header

Refer to gme.h for a comprehensive summary of features.
|

|
||||
|
||||
C and C++ interfaces
|
||||
--------------------
|
||||
While the library is written in C++, an extensive C interface is
|
||||
provided in gme.h. This C interface will be referred to throughout this
|
||||
documentation unless a feature is only available in the full C++
|
||||
interface. All C interface functions and other names have the gme_
|
||||
prefix, so you can recognize a C++-only feature by the lack of gme_ in
|
||||
the names used (contact me if you'd like a feature added to the C
|
||||
interface). If you're building a shared library, I highly recommend
|
||||
sticking to the C interface only, because it will be more stable between
|
||||
releases of the library than the C++ interface. Finally, the C and C++
|
||||
interfaces can be freely mixed without problems. Compare demo/basics.c
|
||||
with demo/cpp_basics.cpp to see how the C and C++ interfaces translate
|
||||
between each other.
|
||||
|
||||
|
||||
Function reference
|
||||
------------------
|
||||
Read the following header files for a complete reference to functions
|
||||
and features. The second group of header files can only be used in C++.
|
||||
|
||||
blargg_config.h Library configuration
|
||||
gme.h C interface (also usable from C++)
|
||||
|
||||
Gme_File.h File loading and track information
|
||||
Music_Emu.h Track playback and adjustments
|
||||
Data_Reader.h Custom data readers
|
||||
Effects_Buffer.h Sound buffer with adjustable stereo echo and panning
|
||||
M3u_Playlist.h M3U playlist support
|
||||
Gbs_Emu.h GBS equalizer settings
|
||||
Nsf_Emu.h NSF equalizer settings
|
||||
Spc_Emu.h SPC surround disable
|
||||
Vgm_Emu.h VGM oversampling disable and custom buffer query
|
||||
|
||||
|
||||
Error handling
|
||||
--------------
|
||||
Functions which can fail have a return type of gme_err_t (blargg_err_t
|
||||
in the C++ interfaces), which is a pointer to an error string (const
|
||||
char*). If a function is successful it returns NULL. Errors that you can
|
||||
easily avoid are checked with debug assertions; gme_err_t return values
|
||||
are only used for genuine run-time errors that can't be easily predicted
|
||||
in advance (out of memory, I/O errors, incompatible file data). Your
|
||||
code should check all error values.
|
||||
|
||||
To improve usability for C programmers, C++ programmers unfamiliar with
|
||||
exceptions, and compatibility with older C++ compilers, the library does
|
||||
*not* throw any C++ exceptions and uses malloc() instead of the standard
|
||||
operator new. This means that you *must* check for NULL when creating a
|
||||
library object with the new operator.
|
||||
Functions which can fail have a return type of gme_err_t, which is a
|
||||

|
|||
|
||||
error = gme_load_custom( emu, my_read, file_size, my_data );
|
||||
|
||||
* If you must load the file data into memory yourself, you can have the
|
||||
library use your data directly *without* making a copy. If you do this,
|
||||
you must not free the data until you're done playing the file.
|
||||
|
||||
error = emu->load_mem( pointer, size );
|
||||
|
||||
* If you've already read the first bytes of a file (perhaps to determine
|
||||
the file type) and want to avoid seeking back to the beginning for
|
||||
performance reasons, use Remaining_Reader:
|
||||
|
||||
Std_File_Reader in;
|
||||
error = in.open( file_path );
|
||||
|
||||
char header [4];
|
||||
error = in.read( &header, sizeof header );
|
||||
...
|
||||
|
||||
Remaining_Reader rem( &header, sizeof header, &in );
|
||||
error = emu->load( rem );
|
||||
|
||||
If you merely need access to a file's header after loading, use the
|
||||
emulator-specific header() functions, after casting the Music_Emu
|
||||
pointer to the specific emulator's type. This example examines the
|
||||
chip_flags field of the header if it's an NSF file:
|
||||
|
||||
if ( music_emu->type() == gme_nsf_type )
|
||||
{
|
||||
Nsf_Emu* nsf_emu = (Nsf_Emu*) music_emu;
|
||||
if ( nsf_emu->header().chip_flags & 0x01 )

Getting Started
|
||||
---------------
|
||||
Build a program consisting of demo/basics.c, demo/Wave_Writer.cpp, and
|
||||
all source files in gme/. Be sure "test.nsf" is in the same directory.
|
||||
Running the program should generate the recording "out.wav".
|
||||
all source files in gme/. If you have CMake 2.6 or later, execute
|
||||
|
||||
run cmake
|
||||
cd demo
|
||||
run make
|
||||
|
||||
Be sure "test.nsf" is in the same directory as the program. Running it
|
||||
should generate the recording "out.wav".
|
||||
|
||||
A slightly more extensive demo application is available in the player/
|
||||
directory. It requires SDL to build.
|
||||
|
||||
Read gme.txt for more information. Post to the discussion forum for
|
||||
assistance.
