Which stack? There are other ways of playing them today if you wanted to mess around for nostalgia-sake and also the creator of HC Simulator is quite responsive to fixing things that might not work quite right :)

The page with my name in the HyperCard 10th Anniversary Stack is a stack I made that was added to that project. It does a bunch of weird things to simulate the Mac Finder, none of which seem to work in the simulator (which makes sense, it's possible that it even uses Apple Script, I don't remember the details).

After finding out that this stack still exists, I also found it on archive.org. It works correctly (although slowly) on the Archive.org emulator: https://archive.org/details/hypercard_hc_10th_anniversary
