GameMusicInfoLib is a C# library that can be used for retrieving info from game music file formats (ie, NSF, SPC, SAP, etc). It also supports reading several module files.

It should be fairly simple to use. For the format you wish to read simply do the following.

For example, say I want to read a Nintendo NSF file:

NsfReader nsf = new NsfReader(/* path to the NSF file here */);

Then you can use the methods within that reader to get info from that type of file.
