Arcade machines have evolved significantly over the years, and so have the methods for updating and patching their games. Traditionally, arcade games were hardwired into the machine’s hardware, meaning updates required physical modifications or replacement of ROM chips. However, modern arcade machines often use digital solutions.

Many contemporary arcade cabinets are equipped with internet connectivity, allowing operators to download updates and patches directly. This is common in systems like Japan’s NESiCAxLive or modern redemption games. Some machines use USB drives or SD cards to transfer updates manually.

For older arcade machines, updates are more labor-intensive. Technicians may need to replace EPROM chips or entire PCBs to introduce new features or bug fixes. Collectors and arcade enthusiasts sometimes perform these modifications to preserve or enhance classic games.

In summary, while older arcade machines rely on physical updates, newer models leverage digital methods for seamless game maintenance. This ensures smoother gameplay and longevity for both classic and modern arcade experiences.
