I have a lot of ancient DOS games t hat I love: Hitchhiker’s Guide to the Galaxy, Leather Goddess of Phobos and many others by Infocom and others. Catalina rendered the previous version of Boxer useless and the developer discontinued it. But now an intrepid programmer covered the discontinued Boxer to a new 64-BIT version that works flawlessly in Catalina. Get your old DOS game, Drag & Drop into the installer window and the new Boxer does it all! I have installed 92 ancient DOS games with no failures! Ran Go64 from St. Claire Software (It’s free), the new Boxer was 100% 64-Bit which likely means it will run on Big Sur.

Good news - thanks John. As it happens I still regularly run the superb database/programming software “Open Access” in Dosbox on a Mac running Mojave. I have been doing this since my first Mac in 2003:
Each major macOS “upgrade” I check whether it still works on a Macbook before upgrading the iMac. This was one of the reasons I have not installed Catalina so now I may try it with the 64 bit version of Dosbox.
There are numerous other 32-bit apps that I am not prepared to relinquish. I also have Parallels so, in theory, I could run them all in Mojave under Parallels running in Catalina (there is a useful tidbits article on this Topic). However the latest (Catalina) Parallels subscription requirements put me off keeping that going just so I can install Catalina.
PS My thoughts about Open Access & disappointment with Windows Software are documented here:
Have you tried CrossOver by CodeWeavers? It will run almost, almost anything from Vista to Windows 10 in 32 or 64-BIT. You can download a 14 day trial that is fully functional and you do not need a Windows OS. Parallels is powerful but it is a subscription and can be a huge draw on your Mac’s assets. I would try both the 64-BIT Boxer and CrossOver. Both function perfectly in Big Sur. Me, I hate DosBox, way too complicated for my old and deficient mind.
Lest there be confusion, we’re talking about two different products here. DoxBox is a cross-platform PC emulation system. Boxer is a user-friendly Mac-only PC emulation system that uses DoxBox at its core.
It’s been my understanding that DosBox has been kept up to date with the latest macOS releases, but Boxer has not (which is why the official page is showing a downloaded dated February 2016). The fact that someone else has done the work to bring it up to date is great news.
I am daft! I cannot remember if I gave the link to the 64-BIT Boxer. Just in case I did not here it is: https://thec0de.com/64-bit-version-of-boxer-for-osx-catalina-10-15/
