The Game Boy version was developed by Tiertex Design Studios, while the other versions were developed by Traveller's Tales. The Sega Genesis/Mega Drive version of "Toy Story" was the lead version. The game features 3D-rendered graphics, and Pixar provided Traveller's Tales with the film's animations of Woody and Scud. The development team and Pixar initially had issues rendering the animations with correct lighting that would allow the development team to convert them for the game. Pixar provided final animations to the team only two weeks before the game was to be submitted to Sega for final approval. If the game didn't receive approval the first time, its release would have been delayed, failing to coincide with the theatrical release of the film. As a precaution, Traveller's Tales rendered their own animations of Woody in case Pixar could not provide them on time.
