I'm stuck. I feel like I've done everything I'm supposed to do, but the LEDs are dead while MAME is running. I'm not running a frontend yet since I haven't found anything I love. So I'm just trying to get things configured straight from MAME.
I'm using an iPACUltimateIO with LEDBlinky 6.6.0.1 and MAME 205. I can make the LEDs light up using the Generate LEDBlinky Input Map. I have a few buttons mapped for testing, like P1START, P1B1 and P1B3. I can run an animation test from Configure LEDBlinky and the buttons will do cool stuff. I have all the boxes ticked that I think should be to make LEDBlinky respond to MAME outputs, like Light Player Start and Coin Buttons, Flash Player Start with Credits, use MAME to trigger start/stop events, etc. I have 'output' set to windows in mame.ini. I've run MAMEOutputTest.exe and observed the text of MAME flashing the player 1 start button. But I'm getting nothing when I actually run Asteroids and put a quarter in. No Flashing start button, no lit player controls, no speak and blink controls on Game Pause.
Can somebody point out the simple thing I've forgotten to do? I'm dead in the water until I get past this.
