Final Fantasy Hacktics

I was able to edit Miluda (Sprint, Job and Skill), edited the second battle, with her so she could join my team.
But the battle is not over, even after killing all enemies, and Miluda does not use any of her lines in combat except the opening sentence,
she appears somewhere else on the screen but invisible.

First of all, I appreciate any help
I'm new using FFTPatcher 492
I would like to ask for help from someone more experienced to include Miluda or Milleuda in my group, either by explaining or creating a patch.
The version I play is the PSX.
If anyone can my help would be very grateful ^^
Already grateful for the attention =)
