This page details one or more prototype versions of Yume Nikki.
There are currently three older versions of Yume Nikki available, each with many differences from Version 0.10. Thanks to Team #LaInvestigaciónYN, v0.04, v0.06, and v0.09 have been recovered from Japanese magazines that distribute freeware games.
All older versions of Yume Nikki were once available on vector.co.jp, where Kikiyama uploaded the game, but the site automatically deletes the previous version each time a new version is uploaded. This combined with Yume Nikki having a substantially smaller following in its early days has led to all versions prior to v0.10 becoming very elusive.
If you plan to play these versions yourself, consider using Locale Emulator to display the text correctly on non-Japanese systems. The Japanese RPG Maker 2003 RTP will also need to be installed. Alternatively, the image files needed from the RTP can be downloaded here, so long as they are renamed to the specified Japanese filenames.
(Note: We recommend viewing the v0.04 page first for context on the differences present in later versions.)
