Controls.dat project question

[Lilwolf]

Since I can't test joystick stuff.  The next item on my agenda (was going to be put off until the next version... but I'm pushing it forward) is to add controls.dat support to my frontend.

I was wondering. 

Would it make any sense for others to create a second controls.guess file (or something similar) that would fill in the controls.dat information from both nplayers.ini and mame listxml to fill in all the blank spaces?  nplayers.ini tells the number for physical players per game... Then mame for the number of inputs... just wouldn't have names per button. 

IE... Games that are not exactly known.  It could make a good guess on the rest?

I can personally get the information from many other sources in the frontend.  But in about the same time, I could  probably generate a secondary xml file in the controls.xml format. 

Last question here.  In the source file now, many games have labels to their inputs (look at setting defenders controls... Smart Bomb is mentioned, but not input 3)  Can we get this information anywhere?  Its not in the -listxml

Anyway... just a question
