Ledblinky: certain games button 1 flakey

[mgb]

I have been messing with setting up my ledblinky and I've noticed that certain games seem to have issues with player 1's button one.
On most games, it's solid with no problems so I know its not a bad wire or ledwiz output, but on some, button 1 will first not light and then it will flash on and off almost like a loose wire but its not. On a few games, button 1 will light white and then go light blue and back.
colors.ini seems to look ok. I will mess around with later this week but I just wondering if anyone has had an issue like this.

Is it possible you have the P1B1 input code set to the mame P1 Start input code and the button is flashing for the games that support flashing the start button when credits are available? But that would not explain the white/blue/white behaivior. It's possible this is a hardware issue.

No I don't have p1b1 mapped to p1 start but I know some games use p1b1 as a start. I'll have to go through it this week and really see which games are doing it. I do have ledblinky configures to flash start buttons and I noticed that is not working.
