Final Fantasy Hacktics

Hey people,
I tried this out a long time ago but my game was wrong.
Im getting a new game now, so Im giving it another shot.
So, my question is, what is the easiest thing I could do?

play it

xD
I meant the easiest thing I could hack.

Use the main patcher program and just start experimenting.  Simplest is to modify the Job stat multipliers and growths (remember, multipliers are good high, growths good low) and the base power of abilities like Cure.  You'll learn most of what you can and can't do as you try out different stuff.  Just... stay away from messing with Lancer, Ninja, Mime, and Geomancer.  I hear Squire, Chemist, and Samurai can have issues too.

Thanks.
Ill leave those alone.
Ill start with the white mage, black mage and knight or something.

The easiest thing to "hack" would be sprites (not spriting, just hacking in different sprites), editing text, modifying stat growthes/skillsets, and changing the numbers used in spells. They all take about as little work to do with the appropriate tool

Allright.
And this can only be done ith .ISO right?

Dammit!
This is just to hard.
I cant even get a .iso!
