Data Design Interactive Lot

In September 2020, 22 HDDs originally belonging to Data Design Interactive were purchased by Obscure Gamers user March42. Most of the drives from the lot appear to have came from the studio's UK office, which went into storage after the company moved to the United States. The contents of the storage unit were auctioned off after the studio went defunct in 2012.
In early 2021, an additional 5 drives from the studio were acquired from a private collector who purchased two PCs that were sold in the same auction.

Dave Mirra Freestyle BMX (Jul 25, 2000 prototype)

An NTSC-U build of Dave Mirra Freestyle BMX for the Sony PlayStation.
Built 25 days before the first available final version for this serial number. [SLUS-01026]
This build is known to have travelled around the internet since at least 2005, but has fallen under people's radar. Saved and preserved back in 2007, this build was re-released on September 7, 2021. The origins of this build are currently unknown.
==Notes==
*There are no FMV's in this build, therefore no movies play in the main menu after being idle either.
*A crash handler is enabled by default in this build.
*All levels and bikes are available in Freeride and Session mode from the start.
*The riders in the selection menu have different photos, Shaun Butler, Troy McMurray and Tim Mirra have a placeholder image.
**Tim Mirra's face is covered with a smiley in the style selection.
*Choosing the "no sound" option in the sound menu crashes the game.
*A set of beep sounds can be heard in-game when on-screen text appears and disappears.
*Some challenge object highlights are different.
*The stage select screen uses different level preview images, some depicting earlier versions of the levels.
**Some of them are missing vertex lighting.
*Two additional test camera options are available.
*The game credit sequence has not been implemented yet.
*Some levels are still unfinished.
**In Vail Trail you can ride on top of the train without being hurt, also there is a section behind a fence where the floor still has collisions and you could be trapped there (the floor collisions were eliminated on the final build, probably to avoid this).
**In Pier 10 water has collisions as any other floor so you can ride on it without drowning.
**In Westward Cliffs there is a section where you can fall out of bounds, this has been fixed on the final build. Also you can't bounce on top of the lifeguard station.
**Some levels have a different starting point.
*The game may crash when falling out of bounds.

Daytona USA (Feb 29, 2012 prototype)

A prototype/prerelease build of Daytona USA for the Xbox 360 from 2012-02-29.
==Notes==
This prototype is playable, but runs slowly. It was recovered from an Xbox 360 development kit. Some files may be missing or corrupted. It is being presented as-is due to the fact that it may be the best remaining copy of this piece of gaming history left in the world, and even if it is not playable, it may be valuable to gaming historians, or it may be possible to create a playable version by combining files from several builds.
Two binaries are included in this release:
* d1cs.xex: Appears to be corrupt		
* default.xex: 2012-02-29 02:00:47 (UTC)
