Introduction
The official platform where information regarding Yume 2kki's development is published is the production wiki, or the Japanese Yume 2kki development wiki ("ゆめにっきっぽいゲームを作るスレ まとめ Wiki*"). As such, it should be noted that YumeWiki is to be treated as a secondary and derivative resource created and managed by the English-speaking community.
This page aims to help prospective and current developers, particularly within the international community, by signposting the game's official policies, procedures, and guidelines for contribution, especially within the context of proxy implementation. It supersedes the original Content Contribution Guidelines page, preserved for historical purposes.
What is Yume 2kki?
Yume 2kki is a fangame of KIKIYAMA's Yume Nikki, collaboratively developed by enthusiasts of Yume Nikki, inspired by said game. As such, despite the name, it is not a sequel to Yume Nikki. Its development began in 2007 and originated in 2ch, now 5ch, a Japanese anonymous message board, where development is still continuing, primarily by Japanese developers.
The game's premise is to explore an expansive dream world, with no explicit goal given to players, leaving players to decide on how to enjoy the game entirely.
Rationale
With the rise of international contributors to Yume 2kki, which is a Japanese project, it should be clear that smooth collaboration towards its development requires proper communication. To that end, the need for cooperation with non-native English-speaking Japanese developers and communities is highly important, and proxy implementation procedures fulfil that need, in the face of existing language barriers.
The policies, procedures, and guidelines as laid out in the production wiki aim to:
- Reduce the burden on Core Developers by defining workflows and scopes for Associate Developers in documenting, preparing, and developing their content,
- Bridge the gap in understanding edits between Core and Associate Developers, and
- Outline shared information between Core and Associate Developers, where Core Developers serve as proxies to Associate Developers, who request the former to formally implement their content.
Resource Links
The wiki that manages information on Yume 2kki's production projects is ゆめにっきっぽいゲームを作るスレ まとめ Wiki* (the Japanese Yume 2kki development wiki).
In addition, official discussion of the production takes place in the production wiki itself and in threads 避難所 (Shelter) and their 5ch thread.
The policies, procedures, and guidelines are published in the production wiki, providing a single resource for all developers:
Map creation must be practiced in accordance with these rules and guidelines.
In addition, the 2kki Toolkit provides useful information specific to 2kki development:
Contribution Beyond Map Creation

Asset Repository Submission
Assets such as art and audio are also provided by the community for developers to make use of. In the repository list of the production wiki's front page, you can find the links to the latest iterations of the asset repositories, where you can contribute audio (referred to as 音楽・効果音優先) or artwork (画像優先).

When dealing with CAPTCHA here, you can also enable Japanese IME for keyboard inputs, though this approach presupposes that you can read hiragana.
