Blood+: One Night Kiss

To do:

Figure out if there is anymore unused maps.
Clarify if the cutscenes in STG9990 are used at all.

Blood+: One Night Kiss is one of two PS2 games from Suda 51's Grasshopper Manufacture that is based on a licensed anime property. However, this one remained in Japan, despite the Blood+ anime airing in North America not long after this game's release.

Debug Menus#

Present in the game are two debug menus. They can be accessed by applying the below codes. The main debug menu will appear when you select the SPECIAL main menu option and then selecting either 制服図鑑 or 翼手図鑑. The second debug menu, Stage Select, can only be accessed when you have control over your character and then pressing L3 + R3.

This option allows you to view models and listen to music. You can also view animations, although it's not clear if that works. To rotate the model in this mode, use the second controller.

YAM#

An effect viewing option. There will be some corrupted stuff on-screen when entering this menu.

WAT#

It doesn't appear anything can be done here. It also contains an unused background texture. You can also move Saya around with the second controller.

Map Select#

Pressing L3 + R3 while you have control over your character will bring you to this menu. From here, use D-Pad Up / Down to select a level ID, or R1 to change options.
