During May 2025, Katharine Chui enhanced the shadps4-emu/ext-SDL repository by implementing support for the Logitech G27 racing wheel’s shifter input, specifically capturing and reporting the state of the 'shifter r' control. She approached this by refining input handling logic and adjusting button counts within the SDL integration, ensuring accurate detection and compatibility for users of the G27 hardware. Working primarily in C, Katharine applied her skills in driver development and input handling to extend the library’s hardware support. The work focused on a single, well-defined feature, demonstrating depth in low-level device integration and careful attention to input path accuracy.
