Then acquire a Pokémon Fire Red ROM with the name: “1636 - Pokemon Fire Red (U)(Squirrels)”
You should then download an IPS patcher. I recommend “Lunar IPS” for Windows.
Then, with Lunar IPS open, click “Apply IPS patch” and select “Clover.ips” downloaded above.
After you’ve selected the patch file, it will ask for the ROM.
Feed it the Fire Red ROM you found on Google. Yeah, that one. It should be called: “1636 - Pokemon Fire Red (U)(Squirrels)”.
If everything went smoothly, you should now be able to play the resulting ROM on your favorite emulator.
