To promote the release of the 2024 film "Sonic the Hedgehog 3", Paramount released a promotional Sega Genesis cartridge that was not only fully functional, but also included a cheat code that revealed the release date for the film's final trailer. The cartridge included three main features: "Characters" (a series of character posters that played a voice clip from said character when interacted with), "Posters" (a collection of posters used to promote the film), and "Unlock" (which starts a minigame where Sonic is chased by Shadow down an endless highway that the player cannot win or lose at). By entering the level select code from Sonic the Hedgehog 3 (up, up, down, down, up, up, up, up), Sonic will say "Hey, I said no cheat codes! ...Okay, just this one." before booting the player back to the main menu. A fourth option, "Trailer?", is unlocked, which revealed the release date for the final trailer as November 25, 2024, before booting the player back to the main menu once again.
