My understanding is that anything can be added as an event. You edit the even.dat to suit your needs (by default it contains lots of 'coin' and 'attract mode' events for use with AdvMame's 'safequit' feature). You need a debug build of Mame to monitor for the Q*Bert death, then add its  CPU memory address as an event under qbert in event.dat
I'm trying to add a few events myself, but don't have a debug build of Mame.

I don't have the source in front of me and , but isn't the knocker an 'event' by default in MAME.  They have a knocker sample.  So they need to know when to trigger that sample and I'd assume they figured it out.  Haven't looked at it for a couple of months so I could be wrong.

If you want to do Serial port, I'd still wait for Buddabings stuff.  His source will be open and writing to the parrallel port will be very similar to the serial port.  Plus he's doing the harder part of making it work in XP and 2000 since you need an additional dll or code for direct access to those ports.

doesn't it seem like this could / should be part (at least software wise) with the LED project? 

And another question.  The knocker.  If you keep power on it... doesn't it just stay out?  I wanted to find a servo (not sure the name) that would allow me to have my control panels lock/unlock from software.  It would be cool to have it combined (IE, its useful for more then qbert... but when playing qbert, it wacks the side... of course it would also unlatch my control panel... might not be a good combo after all :)
