Project DIVA Extend is backwards compatibility with all Project DIVA 2nd data. Here's how you can import PD2nd DLC modules, songs and Diva room items to Extend:

  • Select "オプション" (Option) in the Main Menu.
  • Then select the last option of the list, "Import Additional Data"
  • From there, It has 11 categories to select: Song PV, Modules, Room Themes, Room Items (Floor, Shelf & Wall), Edit Datas (Music, Motions, Backgrounds, Items and Effects).
  • Select each to import all contents in the category.

Any data, such as scores, from DLC PVs from PD2nd are also transferred when the PD2nd savedata has been imported.
