Final Fantasy Hacktics

I've used ShishiSpriteEditor to change the Sprites for characters (the classes) and despite my best efforts I could not save it... I tried looking for a "Patch PSX ISO" option, Save ISO, what ever could have saved my progress... But I got nothing... I've used it once before to change Ramza's sprite but that was nearly a year ago.

Any help rectifying this problem would be greatly appreciated.

This one just auto patches the sprites no saving or checking boxes needed. ..AND it has Refresh. Which makes it almost impossible to have glitches; and speeds up spriting like crazy.
