Superman: The New Superman Adventures (found build of cancelled PlayStation port of Nintendo 64 action-adventure game; 1999-2000)

In 1999, Superman: The New Adventures was released on the Nintendo 64 by Titus Software, a now-defunct French-based studio. Superman 64 was met with overwhelmingly negative reception for buggy controls, bad graphics and terrible gameplay. Soon after its release, Titus commissioned BlueSky Software to commence work on a PlayStation port of the N64 game. However, since the PlayStation couldn't handle the free-roaming Metropolis of the original, BlueSky had to re-create the game from scratch.

The development of this PlayStation version has progressed far enough that magazine ads were published, pre-ordering made available, and the game being officially licensed by Sony Computer Entertainment America. However, BlueSky lost rights to the Superman franchise, forcing them to cancel the game to avoid copyright issues.

Since its cancellation, glimpses of the game had been seen out in the wild on several occasions. The first being a prototype recovered by the PlayStation Museum, who released a short clip in 2007. Another had been seen at game prototype enthusiast forum ASSEMbler Games. On January 14, 2014, an ASSEMbler Games forum-goer had provided an intimate look into the prototype's internal files, including the SLUS code and more, with the condition to release it for a certain amount of cash. The resulting frustration by the community drove the owner to supposedly broke the disc and erased the backup ISO he had, creating tension between him and the forums. Later that year, a forum-goer at the same forum above provided unique footage of a prototype version of the game dated June 22, 2000. On that same thread, another member disclosed that he had possession of that same prototype but misplaced it.
