Hiyaaa! I found another problem, when you go to save a model, it gives you the options to save it, but it doesn't actually save it. Other than that, everything is fine, thank you very much for your effort in optimizing this program!
Hiyaa! How arte you?~ I played a bit with your optimizations that you did, and found a slight problem, animated sprites get bugged, it's not centering the sprites
