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

'[#[Playback (for voting)]
Examples of tools that can play .NSF files include:
- '[[NSFPlay]
- '[[VirtuaNSF] (version 1.0.8.2 is recommended)  
There is a more comprehensive list with compatibility info '[l[http://famitracker.com/wiki/index.php?title=List_of_NSF_players[here]. 

For playback on actual hardware, both the '[l[https://www.retrousb.com/product_info.php?products_id=34[PowerPak] and the '[l[https://krikzz.com/our-products/cartridges/everdrive-n8-pro-72pin.html[EverDrive N8 PRO] (but not the original EverDrive N8!) have built-in NSF players. There is also '[l[https://github.com/bbbradsmith/eznsf[EZNSF] to convert NSF file(s) into a .nes ROM.

'[#[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.
