Throughout Yume 2kki, Urotsuki can unlock wallpapers for her computer under specific conditions or when certain events are triggered.
This page lists all the available wallpapers in Yume 2kki and the conditions required to unlock them.
The wallpaper selected on Urotsuki's "real" computer affects the background on her dream computer, and also influences which character appears in Ending ?.
There are currently 493 wallpapers available to unlock in the game as of the latest version.
They might not appear even if you fulfill the requirements, or take multiple attempts to unlock. It should also be noted that sometimes you may have to do things again, as the game might not have been tracking it until the wallpaper was implemented.
Each wallpaper is listed below by number, along with the conditions necessary to unlock them.
