During June 2026, contributed to dosbox-staging/dosbox-staging by delivering a major user interface enhancement through the integration of the ImGui library as a bundled component with SDL3 backends. This work involved implementing both platform and renderer backends to support ImGui within the SDL3 environment, which improved input handling and rendering fidelity for the project. The integration established a solid foundation for advanced UI elements and streamlined future UI development. Focus remained on feature delivery rather than bug fixes, utilizing C++, SDL, and UI development expertise to enable more flexible and robust interface capabilities for ongoing and future game development needs.
