Game_Music_Emu 0.6.0: 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/. 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.
