I wanted LEDBlinky-style functionality out of my RetroPie cabinet. But I didn't need RGB control or magical frontend integration or anything like that. I had buttons with simple single-color LEDs.
I've got a simple control panel with six buttons per player. All I wanted was this:
- When I launch Street Fighter 2, all twelve buttons should light up.
- When I launch The Simpsons, only the first two buttons for each player should light up.
- When I launch Pac-Man, none of the buttons should light up.
