The Flintstones: The Rescue of Dino & Hoppy

The Flintstones: The Rescue of Dino & Hoppy (Japanese: フリントストーン The Rescue of Dino & Hoppy) is a 1991 platform video game by Taito for the Nintendo Entertainment System and based on the animated series The Flintstones. Taito would later release another Flintstones game for the NES titled The Flintstones: The Surprise at Dinosaur Peak in 1993. An unauthorised ROM hack of the game featuring the head of Mario superimposed over Fred Flintstone's, titled 7 Grand Dad, gained notoriety online after it was played on a 2014 live stream by Joel "Vargskelethor" Johansson of the Vinesauce streaming collective.
