Teenage Mutant Ninja Turtles IV: Turtles in Time · SNES · 1992 · Cheat Code
Effect: Opens a stage select screen allowing the player to begin from any level in the game.
Turtles in Time was one of the most acclaimed beat-'em-ups on the SNES, and its stage select is entered as a Konami-Code-style sequence on the second controller at the title screen. The game's time-travel premise meant the stage select gave access to varied settings from prehistoric jungles to a futuristic skateboard chase, making it appealing for players who wanted to revisit specific zones. Because the exact method differs by region — the Japanese cartridge ties it to a pad code while the US release otherwise relies on a Game Genie — it became one of the better-documented examples of regional cheat differences on the SNES.
