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
|
||||
files and documentation as the changes will allow you to simplify your
|
||||
code a lot (it might even be simpler to just rewrite it). Existing code
|
||||
should continue to work without changes in most cases (see Deprecated
|
||||
features in gme.txt).
|
||||
|
||||
- New file formats: AY, HES, KSS, SAP, NSFE
|
||||
|
||||
- All-new comprehensive C interface (also usable from C++). Simplifies
|
||||
many things, especially file loading, and brings everything together in
|
||||
one header file (gme.h).
|
||||
|
||||
- Information tags and track names and times can be accessed for all
|
||||
game music formats
|
||||
|
||||
- New features supported by all emulators: end of track fading,
|
||||
automatic silence detection, adjustable song tempo, seek to new time in
|
||||
track
|
||||
|
||||
- Updated mini player example to support track names and times, echo,
|
||||
tempo, and channel muting, and added visual waveform display
|
||||
|
||||
- Improved configuration to use blargg_config.h, which you can modify
|
||||
and keep when you update to a newer libary version. Includes flag for
|
||||
library to automatically handle gzipped files using zlib (so you don't
|
||||
need to use Gzip_File_Reader anymore).
|
||||
|
||||
- GBS: Fixed wave channel to not reset waveform when APU is powered off
|
||||
(affected Garfield). Also improved invalid bank selection (affected Game
|
||||
& Watch and others).
|
||||
|
||||
- VGM: Added support for alternate noise shifter register
|
||||
configurations, used by other systems like the BBC Micro.
|
||||
|
||||
- SPC: Removed IPL ROM dump from emulator, as none of the SPC files I
|
||||
scanned needed it, and an SPC file can include a copy if necessary. Also
|
||||
re-enabled supposed clamping in gaussian interpolation between the third
|
||||
and fourth lookups, though I don't know whether it matters
|
||||
|
||||
- Added Music_Emu::load_mem() to use music data already in memory
|
||||
(without copying it)
|
||||
|
||||
- Added Music_Emu::warning(), which reports minor problems when loading
|
||||
and playing a music file
|
||||
|
||||
- Added Music_Emu::set_gain() for uniform adjustment of gain. Can only
|
||||
be set during initialization, so not useful as a general volume control.
|
||||
|
||||
- Added custom operator new to ensure that no exceptions are thrown in
|
||||
the library (I'd use std::nothrow if it were part of pre-ISO (ARM) C++)
|
||||
|
||||
- Added BLIP_BUFFER_FAST flag to blargg_config.h to use a lower quality
|
||||
bandlimited synthesis in "classic" emulators, which might help
|
||||
performance on ancient processors (measure first!). Don't use this
|
||||
unless absolutely necessary, as quality suffers.
|
||||
|
||||
- Improved performance a bit for x86 platforms
|
||||
|
||||
- Text files now in DOS newline format so they will open in Notepad
|
||||
properly
|
||||
|
||||
- Removed requirement that file header structures not have any padding
|
||||
added to the end
|
||||
|
||||
- Fixed common bug in all CPU emulators where negative program counter
|
||||
could crash emulator (occurred during a negative branch from the
|
||||
beginning of memory). Also fixed related bug in Z80 emulator for
|
||||
IX/IY+displacement mode.
|
||||
|
||||
- Eliminated all warnings when compiling on gcc 4.0. The following
|
||||
generates no diagnostics:
|
||||
|
||||
gcc -S gme/*.cpp -o /dev/null -ansi -fno-gnu-keywords
|
||||
-fno-nonansi-builtins -pedantic -W -Wabi -Wall -Wcast-align
|
||||

|
||||
-Wsign-promo -Wunknown-pragmas -Wwrite-strings
|
||||
|
||||
|
||||
Game_Music_Emu 0.3.0
|
||||
--------------------
|
||||
- Added more demos, including music player using the SDL multimedia
|
||||
library for sound, and improved documentation
|
||||
|
||||
- All: Improved interface to emulators to allow simpler setup and
|
||||
loading. Instead of various init() functions, all now support
|
||||
set_sample_rate( long rate ) and load( const char* file_path ).
|
||||
|
||||
- All: Removed error return from start_track() and play(), and added
|
||||
error_count() to get the total number of emulation errors since the
|
||||
track was last started. See demos for examples of new usage.
|
||||
|
||||
- All: Fixed mute_voices() muting to be preserved after loading files
|
||||
and starting tracks, instead of being cleared as it was whenever a track
|
||||
was started
|
||||
|
||||
- VGM: Rewrote Vgm_Emu to support Sega Genesis/Mega Drive FM sound at
|
||||
any sample rate with optional FM oversampling, support for alternate
|
||||
YM2612 sound cores, and support for optional YM2413
|
||||
|
||||
- VGM: Added tempo control, useful for slowing 60Hz NTSC Sega Genesis
|
||||
music to 50Hz PAL
|
||||
|
||||
- VGM: Removed Vgm_Emu::track_data(), since I realized that this
|
||||
information is already present in the VGM header (oops!)
|
||||
|
||||
- GYM: Changed Gym_Emu::track_length() operation (see Gym_Emu.h)
|
||||
|
||||
- NSF: Added support for Sunsoft FME-7 sound chip used by Gimmick
|
||||
soundtrack
|
||||
|
||||
- NSF: Fixed Namco 106 problems with Final Lap and others
|
||||
|
||||
- Moved library sources to gme/ directory to reduce clutter, and merged
|
||||
boost/ functionality into blargg_common.h
|
||||
|
||||
- Added Gzip_File_Reader for transparently using gzipped files
|
||||
|
||||
|
||||
Game_Music_Emu 0.2.4
|
||||
--------------------
|
||||
- Created a discussion forum for problems and feedback:
|
||||
http://groups-beta.google.com/group/blargg-sound-libs
|
||||
|
||||
- Changed error return value of Blip_Buffer::sample_rate() (also for
|
||||
Stereo_Buffer, Effects_Buffer, etc.) to blargg_err_t (defined in
|
||||
blargg_common.h), to make error reporting consistent with other
|
||||
functions. This means the "no error" return value is the opposite of
|
||||
what it was before, which will break current code which checks the error
|
||||
return value:
|
||||
|
||||
// current code (broken)
|
||||
if ( !buf.sample_rate( samples_per_sec ) )
|
||||
out_of_memory();
|
||||
|
||||
// quick-and-dirty fix (just remove the ! operation)
|
||||
if ( buf.sample_rate( samples_per_sec ) )
|
||||
out_of_memory();
|
||||
|
||||
// proper fix
|
||||
blargg_err_t error = buf.sample_rate( samples_per_sec );
|
||||
if ( error )
|
||||
report_error( error );
|
||||
|
||||
- Implemented workaround for MSVC++ 6 compiler limitations, allowing it
|
||||
to work on that compiler again
|
||||
|
||||
- Added sample clamping to avoid wrap-around at high volumes, allowing
|
||||
higher volume with little distortion
|
||||
|
||||
- Added to-do list and design notes
|
||||
|
||||
- Added Music_Emu::skip( long sample_count ) to skip ahead in current
|
||||
track
|
||||
|
||||
- Added Gym_Emu::track_length() and Vgm_Emu::track_length() for
|
||||
determining the length of non-looped GYM and VGM files
|
||||
|
||||
- Partially implemented DMC non-linearity when its value is directly set
|
||||
using $4011, which reduces previously over-emphasized "popping" of
|
||||
percussion on some games (TMNT II in particular)
|
||||
|
||||
- Fixed Fir_Resampler, used for SPC and GYM playback (was incorrectly
|
||||
using abs() instead of fabs()...argh)
|
||||
|
||||
- Fixed SPC emulation bugs: eliminated clicks in Plok! soundtrack and
|
||||
now stops sample slightly earlier than the end, as the SNES does. Fixed
|
||||
a totally broken CPU addressing mode.
|
||||
|
||||
- Fixed Konami VRC6 saw wave (was very broken before). Now VRC6 music
|
||||
sounds decent
|
||||
|
||||
- Fixed a minor GBS emulation bug
|
||||
|
||||
- Fixed GYM loop point bug when track was restarted before loop point
|
||||
had been reached
|
||||
|
||||
- Made default GBS frequency equalization less muffled
|
||||
|
||||
- Added pseudo-surround effect removal for SPC files
|
||||
|
||||
- Added Music_Emu::voice_names() which returns names for each voice.
|
||||
|
||||
- Added BLARGG_SOURCE_BEGIN which allows custom compiler options to be
|
||||
easily set for library sources
|
||||
|
||||
- Changed assignment of expansion sound chips in Nsf_Emu to be spread
|
||||
more evenly when using Effects_Buffer
|
||||
|
||||
- Changed 'size_t' values in Blip_Buffer interface to 'long'
|
||||
|
||||
- Changed demo to generate a WAVE sound file rather than an AIFF file
|
||||
|
||||
|
||||
Game_Music_Emu 0.2.0
|
||||
--------------------
|
||||
- Redid framework and rewrote/cleaned up emulators
|
||||
|
||||
- Changed licensing to GNU Lesser General Public License (LGPL)
|
||||
|
||||
- Added Sega Genesis GYM and Super Nintendo SPC emulators
|
||||
|
||||
- Added Namco-106 and Konami VRC6 sound chip support to NSF emulator
|
||||
|
||||
- Eliminated use of static mutable data in emulators, allowing
|
||||
multi-instance safety
|
||||
|
||||
|
||||
Game_Music_Emu 0.1.0
|
||||
--------------------
|
||||
- First release

||||

|
||||
Getting Started
|
||||
---------------
|
||||
Build a program consisting of demo/basics.c, demo/Wave_Writer.cpp, and
|
||||
all source files in gme/. If you have CMake 2.6 or later, execute
|
||||
all source files in gme/.
|
||||
|
||||
run cmake
|
||||
cd demo
|
||||
run make
|
||||
Or, if you have CMake 2.6 or later, execute at a command prompt (from the
|
||||
extracted source directory):
|
||||
|
||||
Be sure "test.nsf" is in the same directory as the program. Running it
|
||||
mkdir build
|
||||
cd build
|
||||
cmake ../ # <-- Pass any needed CMake flags here
|
||||
make # To build the library
|
||||
cd demo
|
||||
make # To build the demo itself
|
||||
|
||||
Be sure "test.nsf" is in the same directory as the demo program. Running it
|
||||
should generate the recording "out.wav".
|
||||
|
||||
You can use "make install" to install the library. To choose where to install
|
||||
the library to, use the CMake argument "-DCMAKE_INSTALL_PREFIX=/usr/local"
|
||||
(and replace /usr/local with the base path you wish to use). Alternately, you
|
||||
can specify the base path to install to when you run "make install" by passing
|
||||
'DESTDIR=/usr/local' on the make install command line (again, replace
|
||||
/usr/local as appropriate).
|
||||
|
||||
To build a static library instead of shared (the default), pass
|
||||
-DBUILD_SHARED_LIBS=OFF to the cmake command when running cmake.
|
||||
|
||||
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.
