In the Japanese version the priest needs dedicated sprites for his back.
The churches became 'Houses of Healing', with their symbol changed from a cross to a five-pointed star, and the priests became 'shamans' and lost their crosses.
After the title appears, the background changes to red just like in the Japanese version. In the US version, a traditional copyright screen appears first, then it goes to the castle with a blue background. When the Japanese version boots up, it shows the names of some of the main staff members, then the numeral 'IV' appears on-screen, and then the title and castle with the red background appears on the screen.
