Worked on the OpenRakis/Spice86 emulator, focusing on stabilizing system clock timing through targeted system programming in C#. Addressed a critical bug by correcting the assignment of call numbers for system clock counter operations, which involved swapping the handlers responsible for setting and getting the counter. This technical approach ensured accurate timing and prevented malfunctions in the emulation environment. Maintained high code quality by providing precise commit messaging and clear traceability for the fix. The work preserved overall project reliability by improving counter management in key timing paths, demonstrating expertise in emulator development and low-level system operations within a C# codebase.
