I do not own 2nd# myself, but my cousin who I introduced to Project Diva does. From what I've heard it has to do with getting the Extend Modules in 2nd through the PSN store? Since she lives very far away I can't figure it out myself and trying to skype-call and do it without set steps is too difficult. I don't know anything about using the Japanese PSN store on the PSP so... Is that code what I think it is or is it for something else? Since I don't really know and this idea is only based off of mentions about it that I've seen in the forums. How would the code be redeemed? Would the package be usable even if the PSP is logged into a non-Japanese account afterwards? All help would be appreciated!
