Kingdom Hearts: Birth by Sleep is another spin-off title for the PSP. Set ten years before the events of the first game, it revolves around a trio of Keyblade welders that may or may not ended up causing an impact in the game's storyline. It was good enough to get a Final Mix version in Japan, which was later released internationally as part of 2.5 ReMIX.


Miscellaneous tidbits that are interesting enough to point out here.

Unused Areas

The following unused maps are in the initial Japanese release only unless otherwise specified. For cheats, refer to the Notes page. Do note that the names of these maps were taken from BBS0.DAT in the US version.

Unused Items

  • mLight Seeker (ライトシーカー): An unused Keyblade for Ventus that can be equipped, with the design based off the Kingdom Key D. Though the weapon still exists in Final Mix via the code, the model and hitbox have been removed. It can only be found in the Japanese version, an can be re-enabled with the following CWCheat code:
_C0 All Keyblades (Ven only)
_L 0x8172A7CE 0x000E0001
_L 0x10000001 0x00000001
  • XX: An unused Keyblade for Ventus, exclusive to both the original Japanese and Final Mix versions. It has a unique unused icon depicting the Yarn item from The Castle of Dreams, with Japanese text overlaid on top. In the original Japanese version it gives a -84 strength "bonus" and a 57 magic bonus, but in Final Mix, it gives a 20 strength bonus and an 80 magic bonus, and does nothing when equipped nor doesn't change the equipped Keyblade. It can be added to the item list with the following CWCheat code:
_C0 All weapons (only Ventus)
_L 0x8172918E 0x000E0001
_L 0x10000001 0x00000001

Unused Models


PS2 Development Time

Other Unused

Kingdom Hearts 3D: Dream Drop Distance Demo Leftovers

To do:
Replace with models.

In the initial Final Mix re-release, there are some unused 3D models from the demo of Kingdom Hearts 3D: Dream Drop Distance. Interestingly enough, cutscenes can be hacked to include these models, and their animations, fully working. This is also a not-so-subtle hint that Dream Drop Distance uses a modified Birth By Sleep graphical engine. The unused models include:

  • Sora
  • Riku
  • Kairi
  • Xemnas
  • Ansem, Seeker of Darkness
  • Twilight Thorn

There is also the logo of the demo version of the 3DS game, called simply Kingdom Hearts 3D Demo.
