Final Fantasy III (NES)/ROM map

Class and Character Data

• $69B31 to $69B88 - Commands each class can use in battle, four bytes per class

Values for each command:

 04 Attack
 05 Defend
 06 Run
 07 Escape
 08 Jump
 0C Peep
 0D Scan
 14 Item
 15 Magic
 0E Steal
 0B Terrain
 08 Jump
 0F Build Up
 10 Sing
 11 Scare
 12 Cheer

There are no more commands. Putting other values will show garbled text, that will most probably crash the game. You can give commands from one class to another, and they will even get Class Experience, although; curiously enough, they will get a different ammount of exp than the original job in most cases.

Also, to use Sing you need an harp; but you can use Attack with an harp too, making that command somewhat obsolete.

Base MP Values: There are 8 levels of Magic, each one has it's own points. Each chass has one value pointing to one of these groups (Not all of them, there are a few weird ones).

After that they are pretty messy. The offset for these start at $73B98. This will add a certain number of MP to a class. As it's the base MP it will not increase. So if you give a Knight a value of 5 PM Level 1, that character will always have 5 PM (Unless you modify that class' MP gains).
