NES Cheat Codes and Walkthroughs

Original Nintendo cheat codes still work on the NES Classic

Most of the original cheat codes for the Nintendo Entertainment System still work on the NES Classic. Glitches like the Minus World in Super Mario, Easter eggs like a special song that plays in Dr. Mario, and all other NES cheats are intact. Not all games on the mini console have cheat codes, but those that do are identical to their original versions, with one exception. We list them all below.

These cheats apply to the NES Classic versions of each game.
