After doing so, head to the Professor in Pallet Town to get your hands on the National Pokedex. Additionally, you must have completed the story by this time.
To do this, you must have already collected at least 60 Pokemon. While not exactly a straight-up cheat, upgrading your Pokedex is more of a Pokemon Fire Red walkthrough. The first of the Pokemon Fire Red cheats you should know about is how to upgrade your Pokedex. From there, you can play Pokemon Fire Red with ease. You can even play the game on your Android device with the help of the My Boy emulator. Thankfully, there are GBA emulators available for your computer. While some still play it on their Game Boy Advance, others do not have access to this handheld console anymore. Given that the game was released way back in 2004, Pokemon Fire Red is fairly old.
