How to Port a HyperCard Stack?

There is an ancient HyperCard stack [0] I've used long time ago, and I for several reasons I would like to have a modern - ideally open-source - software with the same functionality. I can (in theory) run the stack on various HC emulators (e.g. [1]), but a) it's a bit cumbersome and b) I would love to be able to modify it as I see fit.

The stack seems to have plenty of algorithms and other internal functionalities which can't be easily reconstructed from just using the UI, so I would love to be able to have access to the source code and extract them to another language.

Does anyone have a suggestion how to approach this problem? I've looked into LiveCode [2] but wasn't able to get it to run (and it's apparently not fully compatible with HC anyway). Any suggestions would be more than welcome.
