Worked on the PCSX2/pcsx2 repository to enhance game stability and reliability through targeted debugging and patch management. Addressed a graphical rendering issue in NCAA Final Four 2004 by disabling the mVU flag, resolving a bug where the basketball would disappear during gameplay while minimizing risk to other rendering paths. Later, improved stability for Radio Helicopter II by removing problematic patches that caused game freezes, thereby restoring performance and reducing patch-related regressions. Focused on configuration management and clear documentation to support future maintenance. Utilized YAML for patch configuration and demonstrated a methodical approach to debugging and game development challenges.
