The source code was made available in 2012 at at4am.org.

From 2006 to summer 2008, little development was done on the source code.

The source code being open or not has nothing to do with it.

One still required the game data to actually play the games with the source code.

The full original source code is still available to the public here.

The source code has not yet been released to the public.

But many people wonder if anyone else ever looks at the source code again.

So, you know, these guys are going to post the source code for this.

In particular, this means that source code must be available.

Well, apart from the open source code that they do use.
