FamiTracker

FamiTracker is an open source music tracker program that aims to replicate the audio of the 2A03 sound chip found in the NES, as well as its expansion chips. It was created by jsr, with the oldest released version being version 2.2 in October of 2005. Downloads of both the source code and binaries are hosted on famitracker.com. Currently, the latest stable release is version 4.6, along with a beta of version 5.0 released on the FamiTracker Forums on May 23, 2015. jsr has not released any new version of the program since that day. FamiTracker is a popular program among chiptune musicians due to its precise emulation of its chip and its GUI. There is a sizeable portion of the chip community that only uses the program, and there are many sites that specialize in discussing and sharing music created with it, including the FamiTracker Forums and the FamiTracker Discord Server. It has even seen some mainstream attention: the soundtracks to Shovel Knight and Cave Story for Nintendo Switch were both made in FamiTracker.

Chiptune musician HertzDevil has created two forks of FamiTracker, an improved version called 0CC-FamiTracker and an SN76489 music program called SnevenTracker.
