If a game "crashes without error," developers and technical users use the CUSA ID to track compatibility issues on specific hardware or emulators .

The identifier is a technical Content ID for the digital version of Call of Duty: Modern Warfare II (2022) on the PlayStation 4 for the European region .

In the console homebrew community, users identify this specific ID to apply "backports" or LAN unlock patches that allow the game to run on older system softwares or in offline environments .
