Rope simulation in old games

How the old game developer made Rope simulation.I am talking about cadillac dinosaur.In that game there is an enemy who was able to use a flail to attack player.

They just used static images back then.

If it is a repeated image they usually just drew it one after the other.
Is this what you mean? I think you can see how it was done here. https://www.spriters-resource.com/arcade/cadillacsdinosaurs/sheet/52353/
