Vanilla RTW shieldwall ?

[Watchman]

This may have been covered somewhere at least indirectly (like in one of the threads linked by the top sticky), but is there a reasonable way to use the shieldwall formation from BI in basic RTW ? I would presume doing it involves the -mod: switch and essentially running RTW with the BI .exe, but thus far I've yet to make any progress.

Not that I was very good at this stuff to begin with.

Yes, you're right, you need to run BI with the -mod:my_mod option. You also need to add the shield wall ability to your units. Take a look at this fragment of export_descr_unit.txt in the bi\data\ folder:

type levy spearman frank
dictionary levy_spearman_frank ; Levy Spearmen

You need to change the "formation" line for the RTW units you want to give that ability.
