Game_Music_Emu 0.6.2: Game Music Emulators
------------------------------------------
Game_Music_Emu is a collection of video game music file emulators that
support the following formats and systems:

AY        ZX Spectrum/Amstrad CPC
GBS       Nintendo Game Boy
GYM       Sega Genesis/Mega Drive
HES       NEC TurboGrafx-16/PC Engine
KSS       MSX Home Computer/other Z80 systems (doesn't support FM sound)
NSF/NSFE  Nintendo NES/Famicom (with VRC 6, Namco 106, and FME-7 sound)
SAP       Atari systems using POKEY sound chip
SPC       Super Nintendo/Super Famicom
VGM/VGZ   Sega Master System/Mark III, Sega Genesis/Mega Drive,BBC Micro

Features:
* C interface for use in C, C++, and other compatible languages
* High emphasis has been placed on making the library very easy to use
* One set of common functions work with all emulators the same way
* Several code examples, including music player using SDL
* Portable code for use on any system with modern or older C++ compilers
* Adjustable output sample rate using quality band-limited resampling
* Uniform access to text information fields and track timing information
* End-of-track fading and automatic look ahead silence detection
* Treble/bass and stereo echo for AY/GBS/HES/KSS/NSF/NSFE/SAP/VGM
* Tempo can be adjusted and individual voices can be muted while playing
* Can read music data from file, memory, or custom reader function/class
* Can access track information without having to load into full emulator
* M3U track listing support for multi-track formats
* Modular design allows elimination of unneeded emulators/features

This library has been used in game music players for Windows, Linux on
several architectures, Mac OS, MorphOS, Xbox, PlayStation Portable,
GP2X, and Nintendo DS.

Getting Started
---------------
Build a program consisting of demo/basics.c, demo/Wave_Writer.cpp, and
all source files in gme/.

Or, if you have CMake 2.6 or later, execute at a command prompt (from the
extracted source directory):

    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.
