Game Genie Codes

10,972 codes on 869 games, across 6 systems.

A Game Genie sat between the cartridge and the console and changed what the console read from the cartridge, which is why its codes are letters rather than addresses.

A Game Genie sat between the cartridge and the console and changed what the console read from the cartridge, which is why its codes are letters rather than addresses.

Quick answers

Frequently asked questions

How many Game Genie codes are here?

10,972 across 869 games. By system: SNES (5,488), NES (4,025), Game Boy (912), Game Gear (420), Game Boy Color (113) and Genesis / Mega Drive (14).

How do Game Genie codes work?

A Game Genie sat between the cartridge and the console and changed what the console read from the cartridge, which is why its codes are letters rather than addresses.

Can I use Game Genie codes in an emulator?

Yes. RetroArch and most stand-alone emulators accept them: open the Cheats menu while the game is running, add the code, switch it on and apply the changes. The code still has to match the regional version of the game it was written for.

Are these tested?

No. They come from libretro-database under CC BY-SA 4.0 and are shown with their source file so you can check them. They are separate from our own cheat codes, which carry a "Reported working" or a dated "Tested" label.
