This is just completely out of interest. I only have the PS2 version of the game so modding is completely out of my depth anyway, but would this sort of thing be possible? Putting Jimmy's skin, fighting style and dialogue into an AI model?
I'm really not asking for it to be actually done, as I wouldn't be able to use it anyway, but I just wanted to know if it'd be achievable ... if so, I can imagine him being quite a difficult opponent with his permanent and impenetrable block and vicious 5-hit Combo.
