Interestingly, Danball Senki W saves can be read by the sequel, Danball Senki Wars (PSP). Transferring a W save into Wars unlocks the titular "W" LBX frame—a hybrid mech that combines the stats of the two protagonist robots. Always keep your ULJM06067 folder backed up to a cloud drive or PC; it is the key to the entire trilogy.

In a final showdown near N-City , Ren realizes the save data isn't just a record of the past—it’s a message. By "merging" his own playstyle with the legacy data (a nod to the Sanmi Ittai theme), Ren unlocks a unique, color-changed LBX similar to the special Achilles or Epsilon unlocked via real-world save imports. The data finally deletes itself after the battle, leaving Ren with one final "Little Smile" from the player who came before him.
