Using cheats today

Original cheat devices like the Game Genie, Action Replay and GameShark still turn up second-hand and work with original cartridges. Most modern emulators also have a built-in cheat menu that accepts these formats, so you can toggle codes on and off without extra hardware. Codes can differ between regional releases and revisions of a game; if one doesn't work, try the code list for another version.

Cheats can corrupt save files in rare cases, so back up your saves before experimenting.
