Modular designs in arcade machine construction have revolutionized the gaming industry by offering flexibility, ease of maintenance, and customization. Here are the most common types of modular designs used in arcade machines:

1. Interchangeable Control Panels: These allow players to swap out control setups (e.g., joysticks, buttons, or trackballs) to suit different games without needing a full cabinet replacement.

2. Plug-and-Play Hardware: Modern arcade machines often feature modular PCBs (printed circuit boards) or Raspberry Pi setups, enabling quick upgrades or repairs.

3. Removable Side Panels: Arcade cabinets with detachable side panels simplify transportation, storage, and aesthetic customization.

4. Modular Monitor Mounts: Adjustable or swappable monitor frames accommodate different screen sizes and orientations for varied gaming experiences.

5. Quick-Release Wiring Harnesses: These standardized connectors make it easy to replace or upgrade components without complex rewiring.

Modular designs not only enhance durability but also extend the lifespan of arcade machines, making them a favorite among enthusiasts and commercial operators alike.
