I wish fedorajoe the best of luck for making a fully playable Golbez for Final Fantasy IV.
These are the programs you must be using to make a fully playable Golbez:
FF4kster for making Final Fantasy IV Romhacks.
Translhextion for plain hex view.
Geiger's SNES9X Debugger for decoding ASM and writing new code.
Tile Molester to edit graphics for Golbez.
Cartographer to dump the game's text.
Atlas to insert the game's new text.
For example:

I hope you guys find the correct sprite coding for Golbez's Pressure and new get damaged sprite from Dream Golbez. I've made an example of a new victory pose for Golbez.
