Unused Graphics#
Party Graphics#
A party icon placeholder. Tia's name (in katakana) appears in the image, suggesting this was for Tia placement in the party. In the final release, Tia can accompany you (up to twice) as an escort, but never joins your party.
Menu Graphics#

A background for Ys Origins is included.
Character Portraits#
Full body portraits are used the first time you meet a character. Face portraits are used anytime you converse with non-generic NPCs and party members.
A row of cods. Possibly a placeholder, but the filename is inconsistent with the other face and portrait ones. Dogi's name (in katakana) appears in the bottom-left corner.
Generic face placeholder.
Tia's face portrait with the wrong hair color.
Tialuna's angry/yelling portrait is never used in the final release.
Possible prototype/placeholder for Tia's face portrait.

Gameplay instructions in Japanese were included, but not used in the English version.
These four images appear with the Character Profile graphics.
Possible prototype/placeholder for Tia's full portrait.
Monster Portraits#
These images would normally appear the Monster Book.
Possible placeholder for incomplete images.
Second phase of "ZE-KALIOS", the Moon Dragon boss fight. Only the first phase portrait is used.
Possible prototype for Enemy #51: Bufrol
Possible prototype for Enemy #25: Radit
Unused. Could have been an enemy related to #27: Lapalm and #31: Lapalm-dos. The background also suggests it would have appeared in the Kylos Gorge.
