Never mind this. I see it was a stupid thing to ask.

Hi there. I've never used a debugger before and I'd like some advice or the location of a good tutorial if possible.

What I'm trying to accomplish is to make some changes to Final Fantasy tactics that are beyond the scope of the existing editor.

To get further into detail; what I want is to remove all the restrictions from the Mime job that make it useless for editing purposes. From a programming point of view, I imagine that what I have to do is locate the ASM that checks for the Mime being set and disable it. I figure that once the player applies the Mime job to a unit, the game detects it and applies some restrictions when entering certain menus. Also, during battles it also applies some restrictions. What would I have to do to find the code that does these things and bypass it?

Thanks in advance for any help! =)

After having done some research I *think* I have a good idea of what I need to do.

If I understood correctly, I should begin by finding an address to use as a break point. then I look at the ASM to figure out what I need to change, right?

So, to figure out what happens when I change a unit's job to Mime I start by grabbing a Gameshark code to work with. This'll tell me what address(es) are modified to make the change. And that should lead to the info I want hopefully.

Is that about right or is there something else I should be aware of? Or anything peculiar to PSX debuging I should keep in mind?
