A rare piece of Rockstar North hardware has surfaced in an unlikely place, after a buyer picked up an Xbox 360 development kit for just £5 at a car boot sale and later found early GTA IV files stored on the system, turning a routine purchase into a surprising preservation story that has quickly gained attention among enthusiasts.
A user on GTAForums, janmatant, said he discovered the XDK locally in Scotland and later confirmed that the console still contained data from a November 2007 prototype build of Grand Theft Auto IV, adding that he plans to sell the entire unit instead of separating the data from the hardware.

The leaked build appears to be around 95 percent complete, although it misses key files such as parts of movie data and a critical xbox360.rpf file, which causes the game to freeze and prevents it from running as a fully playable version.
Even so, users digging through the files have already identified early assets, including alternate radio content, beta character models, unused logos, early phone designs, and a ferry model that matches footage from the game’s first trailer.
Some findings also connect to older reports of a scrapped zombie mode called “Z: Resurrection,” which had already appeared in earlier documentation.
While the build does not offer a playable experience, it gives researchers and fans a closer look at how GTA IV evolved before release, and it raises new questions about how such a unique development kit ended up at a public sale in the first place.
