Lost NES game based on Days of Thunder from 30 years ago found
A game based on Tom Cruise's Days of Thunder movie has been discovered by accident. It is a posthumous work and with this it is planned to help the creator's family.
We do not stop insisting on it: the digital preservation of games is very important and is in its infancy. That's why when a game is discovered that did not go on the market and is preserved, it is a milestone, like SimRefinery business simulation game, the version of SimCity NES or a wrestling game of WCW. Today, those efforts have given us a lost game based on the film Days of Thunder, known as Days of Thunder in Spain and Latin America.
Found by chance, and it goes for a good cause
The story of this discovery goes back to the death of Chris Oberth, a programmer who passed away in 2012 at the age of 59, had programmed games like Phasor Zap, Anteater, Ardy the Aardvark and Indiana Jones and the Temple of Doom.
His family donated a huge quantity of hard drives, CD-s and floppy disks to the Video Game History Foundation. They were completely unaware that among them was an NES game based on the movie Days of Thunder starring Tom Cruise, but that never saw the light.

Well, it was actually a different version than what we know of because Mindscape decided to release another version developed by Beam Software. The version that was found today tried to use a kind of 3D graphics, a real feat for the NES.
Video Game History Foundation found the game distributed among 21 diskettes of 5.25 by pure accident reviewing its content, they managed to assemble the source code and they have already obtained a ROM. They plan to open source the source code and release a print run of NES cartridges with the ROM to raise money to support Chris Oberth's family.
