Worked on the PCSX2/pcsx2 repository to address a bug affecting OSDSYS ELF name handling during fast boot, which previously led to incorrect game labeling and user confusion. Focused on refining the command-line argument processing logic in C++, the solution ensured that the correct ELF name is set in the OSDSYS string during fast-boot mode. This targeted fix improved boot reliability and enhanced the user experience by stabilizing argument parsing and ELF name resolution. Demonstrated skills in C++ programming, system programming, and game development, delivering a precise patch with minimal impact to the codebase while resolving a real-world boot-path issue.
