I wonder if he still does in 2020? Or if not, when did he stop?
But, you could also use Mini vMac, which is a very capable emulator.
Mini vMac by contrast is quick, pleasant, and plug n' plug. (It's also emulating a completely different era of course, but it's enough for hypercard.)
And of course, there's a lot of small programs that support the range as well, sometimes just by chance (a Tiger-era program just happens to work), but you're right it's rare for bigger, more-complex stuff.
