Action Replay Codes

9,003 codes on 1,059 games, across 5 systems.

An Action Replay wrote a value straight into the console's memory while the game ran, and kept writing it, which is why a counter it holds never moves.

An Action Replay wrote a value straight into the console's memory while the game ran, and kept writing it, which is why a counter it holds never moves.

Quick answers

Frequently asked questions

How many Action Replay codes are here?

9,003 across 1,059 games. By system: SNES (5,758), Genesis / Mega Drive (2,348), Master System (531), Game Gear (307) and NES (59).

How do Action Replay codes work?

An Action Replay wrote a value straight into the console's memory while the game ran, and kept writing it, which is why a counter it holds never moves.

Can I use Action Replay 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.
