OK... Just one example really. I have a MVS of Magical Drop 3 and JKurtz bios replacement that allows you to change from US/Jap MVS/Home settings. Well, I finally hooked up the switch today and I noticed different animations when I set it to Japan. FOr example they made the intro Title animation animated. heh... and when the book is shown with the 2 characters talking, they zoom in 3d like on the book. Both of these are not present in the US mode. I can understand the title, because it was in Japaneese, but the book zoom in thing was taken out of the US one.
So, I'm wondering how common is this? Missing animations, voices etc... This is the only game that I have I notice do this.
