This set includes nearly 2,500 NSF files that I acquired through out my many adventures on the internets ;). The torrent contains three sets which are as follows...
The somewhat rare Nintendo NES - NSF (Tosec 0.10) set. The set has over 1,000 NSF music files.
The second set in this torrent is the Nes OST NSF set that I downloaded from The NSF Collection. I scanned this set for duplicates that might be in the Tosec set. After I removed the duplicates, it appears that the Nes OST NSF set has 170 NSF unique files that are missing from the Tosec set.
Last but certainly not least is the Unique Nes NSF files set. It includes 1,280 music remixes done on the NES sound chip of current game consoles and even a few mainstream music remixes. This means that you get to hear music from games like Final Fantasy 10 and Street Fighter 2 done on the NES sound chip. How freaking cool is that????? *Get's punched in the head for being such a NES nerd*
You need to have Winamp and a NSF music plug-in to play and enjoy these files. Here is a list of NSF plug-ins. I recommend the NotSo Fatso plug-in. It can play NSF files in stereo and sounds great.
