Electromagnetic interference (EMI) can disrupt the performance of arcade machines, causing glitches or malfunctions. Here are the most effective ways to minimize EMI:

1. Proper Shielding: Use conductive materials like copper or aluminum to encase sensitive components, blocking external EMI.

2. Grounding Techniques: Ensure all circuits are properly grounded to divert unwanted electrical noise away from critical parts.

3. Cable Management: Keep power and signal cables separated and use twisted-pair or shielded cables to reduce crosstalk.

4. Ferrite Cores: Install ferrite beads on cables to suppress high-frequency noise.

5. Optimal Layout Design: Arrange circuit boards and components to minimize loop areas and avoid parallel high-current traces.

By implementing these strategies, arcade operators can enhance machine reliability and longevity while maintaining smooth gameplay.
