assasins query

Does anyone here had use a gameshark to turn their characters into assasins? I just have some questions regarding them:

1. At the battle at the rooftop of Riovanes castle the assasins Celia wearing Barette and Lede Cachusua on their head, but on your modified character they cant wear those accesories on ther head?

2. At the battle at Limberry castle, when the assasins are defeated they turn into Ultima demons, but on your modified character they dont. I dont know if its possible but i think its kind of cool to see them changed too.

while i havent used the game shark on FFT save once when i just got it (froze my game and corrupted the file. it was promptly "disposed of") I think i know the answers to your questions

1) the GS changes the character in a certian slot to the job. was the character you changed male to start with? the GS only changes the skin and job commands not the sex

2) that is more of a story event like killing worker 7 and it reviveing or weigraf
