Well, I called it a hack rather than an emulation layer, and I am open to it being more formal than a patch every time the OS is upgraded. As you noted “I do not track” such things. My HyperCard withdrawal has been alleviated in a way by an MacOS9 emulator that runs on the latest (as of Ventura) hardware and software, and which runs HyperCard. I just found it to be a great prototyping tool for GUI apps that passed messages between objects, quite different from straight procedural programming. Sure, some business probably wouldn’t want to run a legacy app in an emulator of an earlier version of windows. So much legacy software out there.
