Roséverse

Roséverse (formerly known as Olive) is a Miiverse revival developed as part of the Wii U revival project, Project Rosé. Development was led by Project Rosé's founder and former owner david j, until his removal from the team in June of 2026. It is currently available to access on Wii U and on browser under miiverse.projectrose.cafe, with the 3DS version currently in development. Users are able to use Roséverse with Pretendo Network on their Wii U, with Roseverse replacing Juxt when opening Miiverse, though the activation of a Juxt account is required to use Roséverse.

History

Development

Project Rosé, founded by david, initially focused primarily on reviving the defunct Wii U service Nintendo TVii, which was discontinued on August 11, 2015. After a few months, david ceded the role as owner of the project to dorian, but remained its lead developer. david began branching out the project to include a revival of Miiverse, initially known as Olive, a reference to Miiverse's codename.

Development for Roséverse began on November 20, 2025, under its initial name Olive. To prepare for development, david created a rehost of Pear under funnylols.gamer.gd to get HTML files needed to replicate Miiverse's Wii U design. It is meant to replicate Miiverse prior to its 2015 redesign, and thus will not include post-redesign features such as the Play Journal. Features such as friend requesting and profile setup were implemented during November of 2025. Olive development progressed during December, with david being able to implement communities and user profiles. Olive was renamed to Roséverse on December 8, 2025; it is sometimes written without the accent on official posts.

On December 9, 2025, david opened a channel on the Project Rosé Discord server known as #roseverse-tester-applications, for users to apply to become a tester for Roséverse. On December 11, david hosted a Wii U game night with Splatoon; anyone who joined the Splatoon lobby was made a tester for Roséverse. The deadline for tester applications was initially December 24, but was moved a day earlier to December 23 to allow time for developers to enjoy the Christmas holiday.

On December 19, 2025, development began on a feature that allows users to add a URL of any YouTube video and post it to the YouTube Community. In-game user communities were implemented on December 30. On January 1, 2026, compatibility with the Miiverse stage in Super Smash Bros. for Wii U was implemented. Favorite posts were also added.

On January 4, 2026, david announced that a 3DS version of Roséverse was in development thanks to contributions by ZeroSkill. However, development would be slowed down by issues with Cloudflare.

On January 11, david announced that Roséverse's API implementation was almost complete for Wii U games, posting a photo of Roséverse's functionality with Splatoon.

On January 12, Project Rosé team member BoltOneUp announced that Roséverse development would be placed on hold indefinitely. Two days later, on January 14, david announced that Roséverse development would continue, but would slow down due to the team's focus on finishing the TVii revival.

On January 17, david announced that patches for the 3DS version of Roséverse and cross-linking between it and the Wii U version was implemented. In-game posting on the 3DS was also implemented with the help of Rixy, who took 10 hours to get it working properly.

Development on Roséverse was minimal for most of February, as the Project Rosé team was focusing on development of the TVii revival. On February 24, 2026, david announced that messages were implemented to Roséverse, and would announce later that day that live updating messages, a feature that went unused on the original Miiverse, was implemented, albeit with slight delays. david also announced that a public beta for all three versions of Roséverse (Wii U, 3DS, and browser) was scheduled for March 25. However, on March 1, david announced that the public beta would be pushed to April 30 for "private reasons". He also maintained that Roséverse would not be open source, to prevent low-effort copies from being made and so Roséverse would be seen as a proper Miiverse revival instead of simply "another clone". david also posted screenshots of a group chat feature that was still in development; the feature was completed on March 3.

On March 4, 2026, an overview video of Roséverse made by Khentendo was uploaded to the Project Rosé YouTube channel.

On March 12, david announced that the 3DS version of Roséverse was finally partially functional, and that proper development for it would begin. On March 13, he announced that Roséverse's admin panel was in development.

On March 21, david announced that the Wii U and browser version of Roséverse would be coming out on April 2, with the 3DS version coming out sometime between late April and July. A special channel to celebrate the countdown for Roséverse's release was made on March 26, which would be closed and archived upon Roséverse's release. On March 27, david announced that the release of Roséverse would be delayed to April 5. On March 30, david announced that Roséverse now had support for multi-language posts, a feature that was present on Miiverse for announcement posts.

On April Fools' Day 2026, david made a post stating that Roséverse would receive a "copyright-free" redesign replacing any "copyrighted asset" from Nintendo, in order to avoid a lawsuit.

Admin messages and the ability to reply to Miiverse admins, were implemented in early April.

On April 5, 2026, shortly before Roséverse's intended release date, david announced that Roséverse's release would be delayed to April 29, 2026 at 10:00 PM PST, due to personal stress and overestimating the amount of free time he had to work on Roséverse.

On April 7, david announced that users could now view their Yeahed posts, with a special icon displayed on the top left corner for replies. On April 16, he announced that post tags, a pre-redesign Miiverse feature, was in development. On April 18, he announced that ban screens were in development.

On April 19, david posted a screenshot showing the Activity Feed implemented on Roséverse. On April 23, he announced a feature allowing users to make posts to friends and followers on the Activity Feed. On April 25, he announced that profile recommendations would now appear on the Activity Feed; users that were followed by a user's friends or users they followed would be recommended on their feed. Additionally, users could now see their friends and followers lists, and search users based on their PNID or display name via the Activity Feed. On April 27, david announced that communities could now be searched on the "Communities" tab within Roséverse. He also announced that posts with over 300 replies would only show the latest 50 replies initially, with buttons to view older comments.

Promotional images made to countdown the release of Roséverse.

The release of Roséverse was commemorated with special countdown images posted on the Project Rosé Discord server and Twitter account counting down the days until the release. On April 29, 2026, less than two hours before Roséverse's intended release, Project Rosé owner dorian announced that the release would be pushed back a day, to April 30, to fix an unexpected technical issue. The issue was resolved within the next few hours of the announcement.

On April 29, david announced two "guides", Val and Sam, who will serve as Roséverse's equivalent to Miiverse's Tom and Amy, posting announcements on the Miiverse Announcements community for scheduled downtimes, new communities and features, removal of features, and changes to the Code of Conduct, among other things.

Initial Release

On April 30, 2026, at 11:45 PM PST, Roséverse was released for the Wii U, with the required files being uploaded by david. The following day, david added video uploading functionality to the YouTube community, which is otherwise reserved for verified users in every other community. A dedicated art community was also made on that day.

In the afternoon of May 1, 2026, Roséverse underwent emergency maintenance due to getting DDoS'd by the user Omey, a user known for facilitating DDoS attacks on Pretendo Network. Roséverse would be brought back later that day by 4:12 PM PST. Despite the DDoS attack, Roséverse would receive 204 users within its first day of release. david stated that he would continue development of the 3DS and web versions of Roséverse.

On May 4, 2026, david announced that images from the 3DS camera would be allowed on Roséverse, and posted a mockup of dedicated communities for various types of photographs taken with the 3DS camera.

On May 5, 2026, a bug caused all users on Roséverse to get banned, including moderators. The issue was fixed within an hour. Later that day, Roséverse underwent a brief maintenance to add anti-spam measures due to a user spamming posts and accounts, and also to add more communities. When Roséverse was back online, a rate limit of 5 posts per minute was implemented. The following day, Roséverse would go down due to another DDoS attack, but was brought back up within a few hours. By the end of the day, support communities for all characters in Super Smash Bros. for Wii U were made, and were compatible with the game's Miiverse stage.

On May 7, a pop-up was implemented to promote Roséverse on the Nintendo TVii revival. New communities were added later that day.

By May 11, 2026, Roséverse's user count grew to around 630. Later that day, a "Miiverse General Community" was made.

On May 13, the tag functionality that was in development since April had been added. On May 14, the Roséverse friend limit was increased from 100 to 200. The Popular Posts tab was also implemented.

Web Development and Release

david would continue development of the web version of Roséverse throughout May, using dumps of Miiverse's web version from both archive.org and dumps by Arian. He would post development screenshots throughout May. He planned to release the web version of Roséverse on May 22, but changed his mind after realizing that it was very incomplete and lacked testing. An online indicator, similar to the one on Closedverse, was added to the Wii U version of Roséverse on May 25. david completed reply implementation on May 29, and functionalities for the Activity Feed, message list, and user search on May 31.

On June 1, 2026, the web version of Roséverse was released under miiverse.projectrose.cafe. Users are able to make posts on-browser, but need to set up a user password on the Wii U version of Roséverse first before they can sign in.

By June 2, group chats and DMs now update automatically on the web version of Roséverse. Users are also able to embed Roséverse posts on their own websites.

On June 3, 2026, a trailer for both the Wii U and web versions of Roséverse was uploaded to the Project Rosé YouTube channel. The 3DS version of Roséverse is in active development as of June of 2026.

david's Removal From Team

On June 13, 2026, Project Rosé admin Ninuno announced on the Project Rosé Discord server that there would be a server restructuring, and that david was removed from the Project Rosé team, citing internal conflicts and frustrations from the team while working with him. Despite the removal of Project Rosé's lead developer, Ninuno stated that the team had members with fair development experience, and thus development would continue without david's involvement. Ninuno also mentioned that all of Project Rosé's projects would be made open source and contributor-friendly, including Roséverse, despite david's prior statement of refusing to do so.
