The world of arcade gaming has evolved significantly, with modularity becoming a key feature for enthusiasts and operators alike. Modular designs allow for easier maintenance, customization, and game swapping. The most prevalent types include the JAMMA standard, which revolutionized the industry by creating a universal wiring harness. This allows entire game boards to be swapped quickly without rewiring. Another common design is the interchangeable control panel system, where operators can switch out panels tailored for specific games like fighting sticks or trackballs. Multi-Game kits, such as those using Pandora's Box boards, are also extremely popular, offering hundreds of games on a single, easily installed module. Finally, modern DIY and kit-based cabinets are designed from the ground up with modularity in mind, using standardized parts for monitors, controls, and computers, enabling endless personalization and future upgrades.
