Arcade machines, like many modern electronic devices, rely on firmware to operate efficiently. However, firmware updates can sometimes fail due to power interruptions, corrupted files, or hardware incompatibilities. To mitigate these risks, arcade machines are equipped with several mechanisms to handle firmware rollbacks and ensure uninterrupted gameplay.

1. Dual-Bank Firmware Storage: Many arcade systems use dual-bank firmware storage, where the updated firmware is written to a secondary bank while the original version remains intact. If the update fails, the system automatically reverts to the stable version.

2. Bootloader Recovery: A dedicated bootloader checks the integrity of the firmware during startup. If corruption is detected, it triggers a rollback to the last known working version.

3. Manual Recovery Mode: Some machines include a physical or software-based recovery mode, allowing technicians to manually restore firmware using external tools like USB drives or serial connections.

4. Cloud-Based Backups: Advanced arcade systems may sync firmware with cloud servers, enabling remote rollback in case of failures.

These methods ensure arcade machines remain operational even after faulty updates, minimizing downtime and maintaining player satisfaction. Regular maintenance and pre-update backups further enhance reliability.
