and how could I use this in my driving cab? can I get the buttons to blink with the on screen display of Daytona USA? I wouldnt need all of them, thats for sure.
I don't know if LEDBlinky can change animations based on what's going on in game...
I haven't used LEDBlinky yet, although I have purchased it from Arzoo and plan to use it quite heavily once I get around to rebuilding my CP...

But, such things *MIGHT* be possible if you jump through enough hoops. Autohotkey has some sort of bitmap screen search function, where you can specify a small screen snippet and if it sees it show up in a screenshot it can fire off an action. I don't know how processor-intensive that is, but i would guess it's significant. I believe there is a thread where LeChuck or someone else used this to get his 4-to-8-way automated-switching joysticks to switch into 4-way mode in the middle of a Tron game when the light cycle stage started but switch back to 8-way when you progressed to the next stage or got a game over. So, if you're able to identify a little screen area that will always look like a certain pattern when you want your lights to blink (and will NEVER look that way when you don't want them to blink) then you could have autohotkey detect that and then take some action.
At that point, I don't know if you can just pass LEDBlinky a command line parameter to switch on a particular animation or what. Haven't really started messing with it.
The bitmap search seems kind of a kluge, but a powerful kluge. Scrubbing the screen data over and over again has got to take some processor power and it would be so much nicer if the games themselves fired off an event you could use, but since they don't it seems like the screen search could open up some cool possibilities.
