Frequently asked questions
How many NES cheat codes are there here?
21,494 codes across 736 NES games, in 3 code formats: RetroArch code (17,410), Game Genie (4,025) and Action Replay (59).
How do you use these NES codes?
In RetroArch, open the Quick Menu while the game is running, go to Cheats, add the code, switch it on and choose Apply Changes. On original hardware you need the cheat device the code was written for. Either way, the code has to match the regional version named on the set.
Do these NES codes work on any version of a game?
No. A memory code points at a location inside one particular build, so a code for the USA release will usually do nothing on the Japanese or European one. Every set names its version, and where we only have a set for one region, that is the only region it is listed under.
Are these tested?
No. These are third-party codes from libretro-database, shown with their source file so you can check them. They are kept separate from our own cheat codes, which carry a "Reported working" or a dated "Tested" label, and they never count towards a game's cheat total.
