Well all,
Developing this mod simply has taken too much of my real-life time, and I don't really have the time to work on it further. I'm not going to be developing this sub any longer. However, I am releasing the files I have done so far here on subsim, and anyone is free to take up the development of the mod.
I don't like letting people down like this, but I simply don't have the time to keep working on this mod - I've put roughly 60 hours of my time into it so far, and I can't afford to spend any more.
The files can be found
