Project Deluge, the community-driven game preservation effort run by The Hidden Palace, released nearly 500 previously unseen prototypes for the SEGA Dreamcast and the original Xbox on September 18. The drop is part of an ongoing archive that has made hundreds of early builds and unreleased titles available to the public since the project launched publicly in March 2021.
What Project Deluge is releasing
The archive’s library collects prototypes, early retail copies, regional variants and complete games that were never commercially released. Each title included in Project Deluge comes from a single private collector who grants access to the material; the owner appears to verify the uniqueness of each item and document differences compared with the final retail release.
After that verification, an archival team tests the builds, catalogs any exclusive features, and uploads disc artwork so the entries resemble original releases.
Dreamcast preservation process
The Dreamcast portion of the recent release includes 135 prototypes. Because SEGA used a proprietary 1 GB GD-ROM format, these discs can only be read by Dreamcast hardware. To extract data, the dumper used an older Sega boot disc known as System Disc 2 to run the pre-release builds on retail Dreamcast units. That process also allowed the collector to transfer the builds via an SD card reader. The same manual procedure was repeated for each Dreamcast title.
Notable Dreamcast finds
Among Dreamcast discoveries are prototype versions of Illbleed and Tony Hawk’s Pro Skater that include debug modes enabling modification of the original program, plus a version of Sega GT that features Luigi. The release lists multiple recognizable titles from the console’s catalog, including:
- Soul Calibur (1999)
- Crazy Taxi (1999)
- Legacy of Kain: Soul Reaver (1999)
- Tony Hawk’s Pro Skater (2000)
- Time Stalkers (2000)
Xbox collection and technical challenges
The Xbox collection is larger, comprising 349 prototypes—more than double the Dreamcast count. According to Project Deluge archivists speaking to Kotaku, Xbox media are generally easier to rip but less consistent, presenting a different set of preservation challenges.
Many Xbox prototypes arrive on dual-layer DVDs formatted with DVD-Video, while others are on CD-ROM. The variation makes dumping and verifying differences between prototype and retail builds more cumbersome.
Highlighted Xbox prototypes
The batch contains a wide range of unique early builds and unreleased projects. Examples include the oldest known preview build of Psychonauts (2005), a prototype of Jet Set Radio Future (2002), and an early Shrek (2001) build that differs significantly from the final retail game. The archive also contains numerous titles that never reached retail—The Vatz stands out as an especially early demo of a cancelled project, complete with notes outlining objectives and gameplay ideas intended for investors and press.
Scope of the archive and next steps
Project Deluge’s recent additions follow earlier drops earlier this year: more than 700 PlayStation 2 pre-release builds in March and select SEGA Saturn, PlayStation One and CD-i titles in April. The team reports that the archive has now evaluated over 4,000 discs, although some items were duplicates or identical to retail releases.
The Dreamcast and Xbox prototypes published on September 18 are now available for public review through the project’s archive.
