Front that end reads custom control panels

[Joust]

I'm looking for A front end that supports a specific Feature and wondering if its already out there somewhere.

I built a cabinet for Mame that has several control panels setup in different configurations.
Now I'm looking for a front end to use.
I have multiple control panels and want the front end to read a couple lines to see what control panel is inserted and only offer up the games that that panel supports. I can use parallel port pins or keyboard controller pins or whatever.
does such a thing exist? how hard would it be to implement this.
Any coders willing to try?

You probably want to move this to the software section and get the FE gurus there seeing this. 

Interesting question though!  Good luck.

the registration said Newbies should come here.
If a Mod could move this, I'd appreciate it. I don't imagine they want me cross posting the same thing in different forums.
