To actually keep the fireball with a password, you must input the flagged password and hold down , , , and while you press . Otherwise the game ignores the fireball flag.
Even when you possess the fireball you cannot fire it unless you have 8 Heart Tanks.
At least on the original SNES, if you throw the fireball when you do not have all of the armor enhancements, X’s sprite disappears while shooting.
It’s possible and very likely that the fireball code only works in the original SNES version of the game.
