Game Help: how do i teach any move to my pokemon

i'm using google translate, so sorry for any english errors

as you saw in the title, I'm looking for a way to make a pokemon learn any attack in pokemon fire red, it's ok if it's cheats, I just want another special move for my Jolteon, can help me?

We can't give out cheat codes sadly, but if you google 'pokemon firered cheats move modifier' or something similar you'll get results! If you want the Move Maniac (Move Relearner) to relearn old moves, you'll have to go to Island #2.
