During November 2025, Maximum Uranti focused on enhancing the osu! replay subsystem within the ppy/osu repository by addressing a bug affecting cursor stability during replays with the Alternate mod. Using C# and leveraging expertise in input handling and game development, Maximum modified the input blocking logic to reset the last accepted action when rewinding, which resolved misleading red cursor flashes and ensured a consistent cursor state. This targeted fix improved replay fidelity and mod compatibility, contributing to the maintainability and robustness of the codebase. The work demonstrated careful debugging and precise code changes, reflecting a thoughtful approach to subsystem stability.
