Well, I do have programming knowledge, but that is more in the field of 'traditional' languages like C, C++, PHP, SQL and some more, and I can deal with Osiris and Scripts in DOS.

But I have no clue what SWF is and how it works and probably do not understand its concepts, I do not even know, how I could open such a file and look what code it has and even less what that code would do. A game crash would be guaranteed if I even opened and saved such a file without any further changes, I'm sure.
Learning this language only for game modding seems a bit much for my - 'more urbane' (c) Maxine - tastes ;-)

How about more than 5 switchable bars instead of extending the bars of 10 ?
(That's what I personally would prefer anyway, switching bars with 'R' and 'F' is pretty easy.)

That of course would also be impossible if the game had some built-in limit of 50.
