I love SimTower to death, but unfortunately being a Win16-based game, it's kind of hard to get working on modern computers. For some reason, trying to run it in Wine works for a couple of minutes before it causes my window manager to spaz out and crash, and I haven't decided what avenue I'd try to get it working well again.

On the other hand, with all the poking I've done at it over the years, I think I now have the most complete knowledge of the save file format for anyone who doesn't have access to the source code.
