Converting Civilization3 unit animations

[zweihander]

Is it possible to enlarge the images without losing quality e.g. before they are converted into .bmps?

Sadly, impossible.

I suggest to PM imperator1961, who is one of two modders who made many units during Renaissance era(the other one is Sandris) and he still login these days, to ask if he can help.

Edit: if you think this is a good idea, I would like to try to make a contact with Imperator.
