Arcade machines are designed for durability and continuous operation, often relying on redundant systems to minimize downtime. Here are the most common types of redundant systems found in arcade machine hardware:

1. Power Supply Redundancy: Many arcade machines feature dual power supplies to ensure uninterrupted operation if one fails. This is critical for maintaining gameplay during power fluctuations.

2. Backup Control Boards: Redundant control boards or PCBs (Printed Circuit Boards) are often installed to take over if the primary board malfunctions, preventing game interruptions.

3. Multiple Cooling Systems: Overheating can damage components, so arcade machines may include extra fans or heat sinks to maintain optimal temperatures.

4. Dual Storage Drives: Some modern arcade machines use mirrored hard drives or SSDs to ensure data integrity and quick recovery in case of drive failure.

5. Redundant Input Systems: Buttons and joysticks may have backup circuits or sensors to detect and compensate for wear or damage.

These redundant systems help arcade operators maintain reliable performance, reduce maintenance costs, and deliver a seamless gaming experience. Investing in such hardware ensures longevity and customer satisfaction in high-traffic arcade environments.
