I’m interested in doing the same thing. I’ve still got the Quake / Quake 2 / Quake III installation media for Windows somewhere back at my parents place in my old bedroom that they’ve not repurposed for anything else since I left for college back in 2000.
Is there a consensus best, or maybe only, open source line of Quake engine(s) that can run Quake, Quake 2 or Quake 3 on Catalina and if so what files would I need to copy, and to where, to get them to work?
The beauty of Intel based Macs is Boot Camp. I’m considering installing Windows 10 to play CS: Source and DOD: Source. A Windows 10 Home License is only $99.00 from the Windows Store and if you don’t want to pony up right away until you’ve tested things and are comfortable there is no built in shut off date for inactivated copies if you download and install Windows 10 Home via Boot Camp from the latest ISO file that Microsoft has made freely available for download. If you don’t activate you’ll be nagged from time to time and you can’t do some things like customize the Task Bar but outside of some minor annoyances Microsoft has nothing in place to force you to activate so you can try it for a bit to play many of the most popular 32-bit games you can no longer play on Catalina.
That’s worth $99.00 to me. Apple isn’t going to reverse course and add support for 32-bit applications back into MacOS. That’s never been how they’ve done things. Microsoft, on the other hand, will likely support 32-bit applications until 128-bit operating systems and applications become a thing.
