7 Grand Dad adds in a cheat code not present in the game it was bootlegged from, The Flintstones: The Rescue of Dino and Hoppy. By pressing the Select button on the title screen, the player triggers a counter next to the "1992" copyright blurb; this number can be toggled to any value from 1 to 5. While this appears to be a level select code for debugging purposes, due to an apparent glitch, it instead shuffles around the stage order prior to the castle level, which is undone upon dying in-game. Because of the way that this cheat is programmed, the level select feature in the actual debug menu (carried over from the original game) no longer functions.
