All LEDS are on and remain on

[Papamoeziz]

Hello, First of all, thank you for making this, as I have a 4 cart neogeo I have built a cab for. When I try and hook this code/wiring up for game selection, it turns on all the led's, and nothing changes when I change game. I am using a relay module to power some lights, and I can write a code to cycle them, but when I load on your code they all light up and that's it. Would you be able to lend me some ideas? I'm completely lost. Thanks in advance Tim.
