X GameShark codes
How to use: GameShark (sold as Action Replay outside North America) codes are entered on the device's menu or in your emulator's cheat menu. Some games need a "master code" or "must be on" code enabled first, so turn that on if a list includes one.

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.
