Unauthorized modifications to arcade software can lead to cheating, revenue loss, and system instability. To safeguard your arcade systems, consider these effective strategies:

1. Use Secure Boot and Encryption: Implement secure boot mechanisms to ensure only verified software runs. Encrypt critical files to prevent tampering.

2. Regular Software Updates: Keep your arcade software updated to patch vulnerabilities and deter hackers.

3. Hardware Security Modules (HSMs): Integrate HSMs to protect cryptographic keys and sensitive data from unauthorized access.

4. Tamper-Proof Hardware: Use enclosures and sensors to detect physical tampering and trigger alerts or shutdowns.

5. Access Control and Logging: Restrict administrative access and maintain logs to track changes and identify suspicious activity.

By combining these measures, you can significantly reduce the risk of unauthorized modifications and maintain the integrity of your arcade software.
