So for my birthday,my mom ordered Project Diva f for me and showed me that she bought it from a buyer on Bonanaza. I checked out the page and the title says Project Diva F (AS/Asia) and the buyer has another that has JP instead. Both games have different back casing covers and front. For the AS ver it looks like the case with the button shapes with Miku. Whereas the JP looks like the first release case without the shapes Another difference are the region codes. AS has a 3 and JP has 2 and a Japan Only on the back. Are the two completely different games?
