Nintendo Player goes into extensive detail on the game's creation, which was based off of a movie of the same name by TV cartoon production company Filmation (creators of He-Man). The Happily Ever After film, a pseudo-sequel to the famous fairy tale, was originally planned for 1991 but didn't come out until 1993 due to legal and financial issues. When the movie promptly flopped (and when its distributor became embroiled in an SEC fraud investigation), the accompanying NES game that had been developed by Japanese studio SOFEL (Wall Street Kid, Casino Kid) was shelved.
Though a very different SNES version was released by a different developer in 1994, the NES game was thought lost forever, save for a few stray screenshots in magazines and reports from Consumer Electronics Shows past. That is until Sean McGee (who previously unearthed a long-lost Super Mario Bros. 2 sample cartridge) found and purchased a prototype from an Austin-area private seller. Rather than selling the rare game to the highest bidder, as is common with many discovered NES prototypes, McGee dumped the ROM to allow everyone to play this lost gem free on an emulator.
