Dummy Textures

The game files contain multiple dummy textures, probably used during early development stages.

A dummy character was used in place of the character you have by default.

Dummy Final
Generic character Final used in game

Two dummy jackets were used in place of the jackets used for each song.

Normal 512px
Standard jacket Brighter and larger version

A dummy map icon was used in place of the default map icon, despite it being nearly identical minus the watermarks.

Dummy Final
Placeholder icon Final icon

A temporary QR code was used in place of the QR Code in game, which would bring the user to the Chunithm-Net website. Interestingly, the dummy QR code is a standalone image, while the final version is incorporated into the texture file for the User Box.

Additional dummy images include a temporary map background,
