...Because many controllers report different axes and button layouts depending on platform and manufacturer, this project provides a large text database (gamecontrollerdb.txt) that maps those raw inputs to a standardized layout for consistent use in games and applications across Windows, macOS, Linux, Android, and other SDL-supported systems. Developers simply include or load the database file at runtime and call SDL’s API to add mappings, which enables out-of-the-box support for controllers that would otherwise behave unpredictably. The repository encourages community contributions so new or uncommon controllers can be added as they’re discovered and tested.
