Arcade machines, like any digital systems, are vulnerable to software exploits if not properly secured. Here are the most common methods to enhance their resistance:

1. Regular Firmware Updates: Keeping the machine's firmware up-to-date patches known vulnerabilities and prevents exploitation.

2. Secure Boot Mechanisms: Implementing secure boot ensures only authorized software runs, blocking malicious code execution.

3. Encrypted Storage: Encrypting game data and system files prevents tampering and unauthorized access.

4. Physical Security Measures: Locking cabinets and using tamper-proof hardware deter physical attacks that could lead to software exploits.

5. Network Isolation: Disconnecting arcade machines from the internet or using firewalls reduces remote hacking risks.

6. Anti-Tamper Software: Deploying tools that detect and block unauthorized modifications safeguards the system.

By combining these strategies, arcade operators can significantly reduce the risk of software exploits, ensuring fair and secure gameplay for users.
