...oh, you mean LWA files are just
text files? Someone should have said....
Something like that would cover/help front-ends lighting the right buttons per game (although by the look of it a couple of frontends have native LEDwiz support and will light buttons as you scroll a game list - is this right?). I'm away for the next 10 days or so, but if it would be handy I'll look at a game-LWA creator when I'm back...
My question was more geared towards the new input/output and event system now in mame: Player start buttons flashing on coin-up, Mr.Do fire button flashing when fire is activated etc..etc.. Powermame could do that, but it did it prior to the new mame system, so it would be all change - the new system is designed for a 3rd party app to light buttons or whatever. I guess I am not really across the current LED-Whiz supporting apps properly.
