Morse Runner is a Windows-based contest simulator developed by Alex Shovkoplyas, VE3NEA. Using Wineskin, it has been successfully and seamlessly run under OSX, and made available here for download. Sure, you could use Wineskin to do this yourself (and save me some bandwidth), or you can pull the ready-made dmg from here.
Running Catalina? Go to 'Download' to read the latest (and grab a box of tissues)

Without specific context, it's challenging to provide a detailed analysis. However, we can speculate on several aspects:
This means that for the foreseeable future, users reinstalling Windows on modern Intel systems will need to become familiar with f6flpyx64vmdzip. The "non-VMD" driver is a legacy compatibility tool, primarily for older hardware or advanced users who disable VMD for specific reasons (e.g., better Linux compatibility or older backup software). f6flpyx64nonvmdzip and f6flpyx64vmdzip

MANY reports that it DOES NOT work on Catalina. It is very unlikely that it will work under Catalina in the near future, as it would require some pretty hefty development on Wine (they're working on it). The only other option I see is for some nice macOS developer to take the original code (it's open source!) and re-write it to run natively on 64bit macOS (go ask any developer, this is a lot of work). Since Xcode is now free if you're running Catalina, I'm happy to give it a try... when I can afford to buy a system that can run Catalina :)
