 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
-	-Wcast-qual -Wchar-subscripts -Wdisabled-optimization -Werror
-	-Winline -Wlong-long -Wmultichar -Winvalid-offsetof
-	-Wnon-virtual-dtor -Woverloaded-virtual -Wparentheses
-	-Wpointer-arith -Wredundant-decls -Wreorder -Wsign-compare
-	-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.
