The graphics (title screen plus whatever other changes) and converting from NTSC to PAL could have taken placed at Konami in Japan. Could've made the prototype to give to their European branch for them to see how things are going along and if any changes need to be made. But then, I don't know if that's how things work; I always assumed another region would get the game after it was completed in Japan.
Could be phony, might not be, dunno.
