Surely you wanted at the very beginning of Pokemon Fire Red to get Bulbazaurus, Squirtle and Charmander right away?
So, there is a way!
Follow the instructions below!
Go into the game and click on "Cheats" in the emulator menu (If you do not have such an emulator, then download "MyBoy" or another emulator that has cheat codes.)
Click on the "New cheat" button.
Then it opens.
"Cheat name" is the name of the cheat. (Optional)
"Cheat type" - type of cheat. (Do not touch.)
"Cheat code" - cheat code. (Fill in)
Fill the menu "Cheat code" code:
(There are zeros everywhere, but you can just copy this and paste it into the emulator)
ATTENTION, CHEAT WHILE LET BE TURNED OFF
Paul done! Now we can return to the game.
We reach the moment of choosing Pokemon.
We approach any start-up.
After you are prompted to give the nickname to the starter, go to the cheat panel, turn on our cheat.
After that, we "step" towards another pokeball and select another pokemon.
After this dialog message, turn off the cheat and take this Pokemon. And with the third, do the same and voila.
The table is clean and you have all three start-ups!
I hope I helped you, I advise you to stay in front of the entrance to Dr. Oak. If something does not work, make sure that you are doing everything normally.
