The struck pose goes like this:

You can take Paladin Cecil's Victory/Struck Poses and edit them into Golbez poses. As it seems, Golbez's battle sprites mostly use a lot of Dark Night Cecil battle sprites so using that palette as a reference will make editing new battle Golbez sprites for Golbez easier.
Fedorajoe, there's a new program called png2snes where it converts Color-Indexed PNG files to the graphics format used by the SNES. It can generate binary files or text files that can be linked with WLA-DX.
I have a new struck sprite for Golbez. It uses the Tellah Block with Paladin Cecil Block, and Dark Knight Cecil Struck sprite combined but edited to look like Golbez.
Here are the two sprites I've worked on for Golbez during my free time and I hope they work.
Also, you can bring back the get damaged sprite for Edge which will be used only during the Edge vs. Rubicante cutscene in Final Fantasy IV: Playable Golbez Edition.
