Worked on stabilizing sprite rendering for the GunBustr game within the mamedev/mame repository, focusing on resolving a persistent visual glitch. Addressed a bug in the C++ codebase by adjusting the sprite y-coordinate logic based on flip state and correcting rendering offsets, which improved the accuracy of sprite placement. This targeted fix reduced user-visible glitches and aligned with the project’s quality and performance goals. Demonstrated strong debugging skills and a deep understanding of retro game emulation pipelines, particularly in C++ and game development contexts. The work contributed to more reliable sprite rendering and reduced support overhead for the GunBustr title.
