As someone who doesn't have a large musical vocabulary, I'm looking for resources that can help me refer to specific instruments in retro game music.  I've found myself diving into retro game music over the past year, but I often have trouble talking with other people because I don't know what to call various instruments.  I'm not exactly sure what I'm looking for, so take these questions for what they are worth:

Are there libraries of common instruments used in, say, NES, SNES or Genesis games that are named for what I could call them? 

Are there articles that take famous soundtracks and discuss how they are put together in terms of their component sounds? 

Even a wiki that lists the prominent instruments used in each track of a particular game would be a start for me.
