Arcade game manufacturers face unique challenges when updating software for older machines, as these systems often rely on outdated hardware and proprietary technology. To address this, manufacturers employ several strategies:

1. Patch Releases: Some companies release patches or minor updates to fix bugs or improve performance, often distributed via USB or specialized hardware.

2. ROM Replacements: For deeply embedded systems, manufacturers may provide updated ROM chips to replace outdated ones, ensuring compatibility with newer software.

3. Emulation Solutions: In some cases, manufacturers use emulation to run updated software on older hardware, bridging the gap between legacy systems and modern requirements.

4. Third-Party Support: Independent developers and communities often create unofficial updates or mods to extend the lifespan of classic arcade machines.

5. Limited Support: Due to cost constraints, some manufacturers discontinue updates entirely, leaving older machines as-is or encouraging upgrades to newer models.

By balancing preservation with innovation, arcade game manufacturers keep retro gaming alive while adapting to evolving technological demands.
