New Astro City and Blast City in the US

Just a little update, looks like it was the lack of grounding all along! Buttons 4 and 5 work great now. Buttons 6 are still acting weird, requiring both 5 and 6 to be pressed to work properly, but I can probably figure that out on my own with some continuity tests. As a little tax, here's a picture...
