NotSo Fatso plays standard NSF files, as well as NSFE files. NotSo strives to be as accurate as possible, while still being quick. All expansion chips are emulated.
NotSo provides several options not available in other NSF players, such as stereo output with channel panning control and pseudo-surround sound effects, silence detection, configuarable sound filters, and much more.
NotSo also provides several alternatives for interfacing with Winamp. There are 2 dialogs to choose from to flip through tracks of the NSF, or NotSo can use the prev/next arrows in Winamp, or you can use NotSo's "shadow" feature to put each individual track in Winamp's playlist.
This is an excellent download for anyone who spent fair amounts of their childhood playing the old 8 bit Nintendo games. Notso Fatso allows you to play the music files (NSF) from all the old Nintendo games in Winamp. This is definitely the most complete and customizable NSF player for Winamp I've seen... many many options available.
