How to unpack an old game under Clickteam Multimedia Fusion 1.5?

Question

Game development

Yesterday I read an article on Habré about reversing and fixing errors in an old Flash game.
I remembered that I had been fond of a toy written in Clickteam Multimedia Fusion 1.5 for a long time.
How to unpack it completely and get a project with all the resources?
Even if I don’t understand the code, then I’ll do something similar in terms of resources.
The toy of the early 2000s, the organization that produces it has long been gone.
