I built my (second) Picade last week and I’ve got some issues with some of the buttons. I’ve just flashed the PCB with the latest rom but the problem persists.
I’m using Retropie, but I exit to the terminal to try this so it doesn’t seem software related.
So the thing is: I exit Emulation Station to the terminal. I have my panel open for easy access to the PCB. If I press one of the mentioned buttons (1, 2 and 4), the TX led does light up as does with any other button. But for those three, I get no key press in the terminal.
