Does it run at all? (Can you play for a while, or does it just perpetually
reset when in play mode?)

(If it plays for a while and dies, I'd watch the power supply closely with a
meter or scope. My BZ was glitching during play-- turned out the +5 rail
was browning out to around ~3.6V from time to time. I shotgun debugged it
with a spare ARII and it's been fine ever since...)
