The nsf format is a specific format of music created on the 2a03 only, available in NES/Famicom consoles. See nsfplus (format) on the nsf extended format and nsf_classic (format) for the more limited format.

NSF stands for NES Sound Format, but this is frequently mistaken as Nintendo Sound Format.

Restrictions on submit

The nsf format is for 2a03 only; expansions are accepted in the nsfplus format.

Accepted file format


A common beginner's mistake is to submit a FTM (FamiTracker Module) to a NSF compo instead of an NSF file (don't do this!).

Playback (for voting)

Examples of tools that can play .NSF files include:
- NSFPlay
- VirtuaNSF (version is recommended)
There is a more comprehensive list with compatibility info here

Render to MP3

Both NSFPlay and VirtuaNSF can render .wav files from .nsf files; note that in some cases, such as when a song is longer than five minutes or loops forever, the output length will need to be specified and/or the resulting file will need to be trimmed. After rendering to .wav, a sound editing tool such as Audacity can be used to normalize the sound file, add a fade out to a looping track, and convert the (minimally) edited song to an .mp3.
