Worked on enhancing the momo5502/emulator project by improving WOW64 compatibility through precise alignment of syscall ID handling with Windows semantics. Focused on system programming challenges, the developer updated syscall_dispatcher.cpp to ensure that syscall IDs are managed in a manner consistent with native Windows behavior, addressing emulation accuracy. The work included clarifying documentation to explain dispatcher wraparound semantics, supporting maintainability and future development. Using C++ and leveraging the Windows API, the developer also corrected a minor comment typo to improve code readability. The contributions reflect a targeted approach to emulation fidelity and documentation clarity within a complex system programming context.
