Arcade machines have evolved to cater to global audiences, requiring sophisticated language localization for both on-screen text and audio. For on-screen text, developers often integrate multilingual ROMs or software that detects regional settings, dynamically displaying the appropriate language. Some machines use replaceable graphic overlays or modular displays for quick language swaps.

Audio localization is more complex, involving pre-recorded voice lines or synthesized speech in multiple languages. Modern arcades may store audio files for each supported language, triggered by the system's region settings. In some cases, text-to-speech engines generate real-time audio translations.

The localization process considers cultural nuances, ensuring translations feel natural to players. This attention to detail helps arcade games maintain their immersive appeal across diverse markets.
