Making the game allow me to siege assault on the strategic map w/o siege/infantry

Hi Dol_Guldur.

I am looking at GAFM right now. I haven't actually played it because I don't want to overwrite what I've done so far.
(is there a way to play this without overwriting the "original" data folder?)

I've looked at your "fom balor eye" thing.

Questions:
How does it look in game? (giant floating eye?)

What is its firing rate (as in how fast does it shoot)? (like regular onagers?)

How did you take care of the "loading/reloading" animation and the sounds associated with it? (it's still there or no?)

Are the crews visible? (isn't it still possible to make the # of crews 1?)
Can it move through forests in the battle map? Strat map?

How fast can it move in the strat map/battle map?

Did you use 3d modeling to make a new balor eye skeleton?

Does the onager skin still show? Or is it a giant eye, despite using the "onager" entry in the "engine type"?

Do the "onagers"-aka eyes- have similar hp as regular onagers?
