Description: FamiTracker is a free windows tracker for producing music for the NES/Famicom-systems.
Other: On the first run, FamiTracker sets up file association with the ftm file type, which is the project file type for FamiTracker. I haven't checked where these registry entries are, unfortunately, and can't check because I'm not at my own computer.
