=== Electrical Testing ===

'''Power-Off Tests:'''
# Check continuity across each capacitor (should charge then read open)
# Verify no shorts between power and ground
# Test resistance between 5V rail and ground (>1kΩ)

'''Power-On Tests:'''
# Measure 5V rail: 4.85V - 5.15V acceptable
# Check for AC ripple: <100mV peak-to-peak
# Monitor voltage stability during gameplay
# Verify audio presence and quality
# Check for video artifacts or instabilities
