Patching a game


Most patchers work the same — they require a patch, a ROM, and sometimes a location to save the finished ROM. Click Apply and you’re done!

ROM Patcher JS can be used on any device with a web browser to patch your games.



Alternative apps you could use include the following:The process is largely similar whatever you use — supply a ROM, supply a patch, and then save your patched ROM somewhere. And you’re done!


Making sure you’re patching the right game


To ensure that you won’t run into problems, make sure you’re patching to the correct ROM — check with the author of the hack to ensure you’ve got the right ROM. Double-check, especially if your game doesn’t load later on. You can check if you’re using the correct ROM by looking at its CRC32, MD5 or SHA-1 checksum, which ROM Patcher JS will show you.

The CRC32 and MD5 checksums for a typical Pokémon game:
  • Pokémon FireRed (USA, version 1.0) — CRC32: dd88761c / MD5: e26ee0d44e809351c8ce2d73c7400cdd
  • Pokémon Emerald (USA/Europe, version 1.0) — CRC32: 1f1c08fb / MD5: 605b89b67018abcea91e693a4dd25be3

Some patches will be checked by the patching app, and will raise an error if the ROM isn’t correct:


Do not ignore these errors, as they may lead to errors down the track.
