Extended Nintendo Sound Format is like the NSF format except that it allows for individual track titles and timings. It can also alter the order of tracks, as well as mark tracks that should be ignored by the player. It allows NES music to output in Stereo. 2 Square Waves, 1 Triangle, 1 Noise and for later games PCM. Japanese games also used an extra channel (on the Famicom Disk System) that the NES music didn't have.
