Note: if you are logged in to a non-Japanese Sony Entertainment Network account from a web browser, the above links likely will not work (you need to either be logged into a Japanese one, or log out from SEN completely.) Because PSN is experiencing ongoing problems after the recent Christmas network attacks, these links to the store may not always work.
Also, DLC's purchased for either the Complete Edipyon! or Special Edipyon!, will be usable in either version of the game. Furthermore, any DLC's purchased for Special Edipyon!, will also allow downloading of the equivalent DLC for Zero Portable on the VITA at no extra cost!
