You see, i want the faces to be 96x96 in size, since i'm going for something that Oneshot has.Can you clarify what your actual question is? Are you trying to resize RPG Maker's UI elements to make the smaller faces look appropriate?
Or, since you use the word scaling, are you wanting to make these smaller faces fit into the 144x144 slots?
You'd just use an image editor to do that.
