SimEMU 602 relies heavily on virtual COM ports. The original v22 had a memory leak when communicating via FTDI or Prolific chipsets. The fixed version patches the comm.dll file, reducing handle leaks by approximately 95%, allowing for 72-hour continuous test runs.

The "Fixed" designation in version 22 is the standout feature here. Previous iterations often suffered from communication timeouts and compatibility issues with modern USB-to-Serial drivers. This update successfully patches those "Error 01" and "No Card Found" bugs that plagued earlier releases, making the writing process significantly more stable on Windows 10 and 11.
