first, what I'm using:
hex editor - xvi32
emu - visual boy advance
ROM - *.gba
save state - *.sav
game save - *.sgm

my goal is:
     - modify the job classes
          *change each jobs base movement, movement type, swim type, and emblem availability.
     - document anything that might be useful

i haven't found anything.  Not even stuff that should be easy to find, like the money modifiers.  i think that the ROM, save state, and game save are formatted to make it easy for the emulator to read them, and that formatting makes it unintelligible to me.
so does anyone know of any other game boy advance ROM formats that work with visual boy advance, or any other emulators for game boy advance?

Also it's not the ROM or savegame format that's tripping you up as all of those are raw data. You're either not looking hard enough or the data is compressed.
