This would be awesome. Then we could get LEDBlinky to only light up the start button when credits are inserted but for ALL games and not just really old ones.
For pincabs running DOF controlled lighting and feedback, I'm able to pull off some really cool effects with addressable leds for MAME games using a new beta version of DOFLinx. I can have any lighting effect controlled with a key or button. So Galaga when starting has a cool led starfield around the game screen. When I push start I can have any word I want flash at the back of the screen. When i press the fire button I have red led lazer blast effects on the sides of the screen.... very cool stuff that I've been doing with Future Pinball for a while (only that is way cooler).
...but having a program that could either detect specific sounds being played, or detect game functions would allow me to do animated addressable led lighting for "explosions" or other game events to do some really cool stuff.
Even if its not game related there's got to be some program that will recognize certain sounds (like voice recognition) and trigger commands or keys....
