Unauthorized hardware modifications in arcade machines can lead to financial losses, security breaches, and operational disruptions. To safeguard your arcade machines, consider these effective strategies:

1. Use Tamper-Proof Hardware: Install specialized screws, locks, and enclosures that deter tampering. Tamper-evident seals can also alert you to unauthorized access.

2. Implement Physical Security Measures: Place arcade machines in well-monitored areas with surveillance cameras. Secure the location to restrict access to authorized personnel only.

3. Firmware and Software Locks: Utilize password-protected BIOS settings or custom firmware that prevents unauthorized changes. Regular updates can patch vulnerabilities.

4. Hardware Authentication: Integrate hardware dongles or cryptographic chips that verify the machine’s integrity before booting.

5. Regular Inspections: Conduct routine checks for signs of tampering, such as broken seals or unusual hardware additions.

By combining these methods, you can significantly reduce the risk of unauthorized modifications and ensure the longevity and security of your arcade machines.
