Final Fantasy Hacktics

So how would i go on doing this? And would that person be a starting unit at the beginning after first fight? Sorry I'm doing this over phone and at work ha but yeah how would I do this lol I'm new to this hacking I used patches but not made my own

I wanna like the second person to be septh from ff7 and only that person would be him and not every other squire...... I tried to do it once but every male squire was him and where only he will know the job

I'm new and I'm trying to make my own jobs like how they did in journey of the five so I would appreciate the help please and yes I've looked around but could not find it

OK I hope some one can help but how come I can't patch the game with this patch? Doesn't show up

I'm new and I've been playing jot5 and I love it! Can't wait for chapter 2
