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 :)
