No, Frets on Fire is not done. As a matter of fact, FoF is being rebuilt in c++ at the moment. the FoF Core, the game engine will be available on github once its stable.

I just checked the link and nothing is there, so they are still working on it or gave up. I hope it is not the latter.
I also found this post in another topic way at the end. The topic subject is misleading and very long and old.
Not talking about FoFiX, talking about the origional FoF. I posted a thread the other day of our plans for the game. The code has been uploaded to our github project organization.

I am guessing the thread he mentions in the bottom quote is actually the post I found at the top
I have been to the sourceforge link it explains more of what they want to do with the program.
I personally don't know python or how to use github, but if you do you can probably help patch it up before it gets deep in to c++ build. The more stable the python code is, it is most likely the initial c++ version will be stable.
