Final Fantasy Hacktics

Hi, I want to try making my own mod too and I've seen that a lot of the popular mods/hacks have level scaling, changing the value of mp regen, and removing luso as a required unit during story missions. I know you do these things through hex editing, but where can I find the offsets to change this? How does the other hacks do this?

I found things like max mp here on this forum but can't seem to find any info on how people do everything else?
