Worked on enhancing arcade hardware emulation fidelity within the mamedev/mame repository, focusing on a targeted bug fix for Double Dribble’s sprite rendering. Addressed an edge-case issue by refining the X-axis wraparound logic in C++, ensuring sprites correctly wrap at the 255-pixel boundary to match original hardware behavior. This adjustment improved graphics programming accuracy, reducing visual glitches at screen edges and supporting authentic gameplay reproduction. The code change was isolated to the relevant logic, minimizing impact on surrounding systems and aiding maintainability. Validated the fix against hardware references, contributing to ongoing efforts to improve emulation accuracy and regression testing reliability.
