NES Sound Format
NES Sound Format (NSF) is an audio file format invented by Kevin Horton, to provide a way to transfer Nintendo Entertainment System (NES) music data. NSF files consist of the original music / sound code from a NES game and some header data.
While the original intention was to allow storage, transfer and playback of music / sounds ripped from NES games, the format has become popular with composers of chiptunes and many original compositions are now available.
Examples of NSF files can be found at:
