Worked on the libsdl-org/sdl2-compat repository to enhance cross-version compatibility for SDL-based applications, focusing on stability improvements for GoldSrc games and Windows environments. Addressed a critical bug by refining SDL_GL attribute handling, ensuring correct mapping for values above 19 to prevent black screen issues. Improved the reliability of SDL_GetWindowWMInfo by introducing version checks before accessing Windows-specific handles, reducing runtime errors on older SDL versions. The work demonstrated careful defensive programming in C, with a strong emphasis on graphics programming and Windows API integration. These changes reduced user-facing bugs and contributed to more robust SDL library compatibility across platforms.
