Well, honestly, I was being lazy.  What I really meant was, was their a C-like compiler implementation AND did they create a "standard library" of very common tasks that one would execute on an NES.  

 

There is C compiler with bundled stdlib and a library that is not really suits to be used in actual games (may be used for initial experiments), and a few (three, I think) third-party libraries that perform all common tasks needed for real games. There is like 30 NES homebrew games written in C in recent years, some of those with open source code.

Does one have to go digging around on NESDev to find them?  Or is there a running list with links somewhere?
(not NES homebrew games in general, but something that specifically includes/denotes the games made in C)

 

I don't think there is a list yet. Good idea to make one, wait a bit, I'll make another thread.
