=== Cartridge Slot Cleaning ===
The 36-pin edge connector accumulates oxidation that prevents proper cartridge contact. '''Never clean the cartridge slot while power is connected''' - the slot receives 5V even when the console is switched off, and cleaning while powered will permanently damage the system.

'''Safe Cleaning Procedure:'''
Disconnect all power sources and press the power button to discharge stored energy. Clean the connector using a cotton swab moistened with 91% or higher isopropyl alcohol. For stubborn oxidation, use a pink eraser on a wooden stick, ensuring no eraser debris remains in the slot. Commercial cleaning kits designed for edge connectors provide the safest approach. Allow complete drying before reconnecting power.
