RTW Campaign with BI exe - a few questions

[AmbrosiusAurelianus]

Will phalanxes still work, since I don´t know yet whether any BI unit has phalanx capability?

No one has answered this yet, and I would also be interested in hearing what people know about this.

When playing the BareBones mod through the BI.exe, I saw a unit that stood in the fake phalanx formation, but still had the option to form phalanx. When I pressed the key for phalanx mode the unit redeployed slightly and moved into the traditional phalanx.

Does this mean that some units can be a sort of hybrid between the old phalanx and the new? If so this could be potentially useful in campaign, because the fake phalanx could charge and the old one could not. Perhaps using the BI.exe gives the best of both worlds.

Actually, I don't know what to enter in the EDU to give a fake phalanx in BI. Is it the same as for the traditional phalanx in RTW?
