Without an Action Replay, there is no easy way to fill the National Pokedex.
there was a code to fill in missing numbers for the pke dex but it would completely mess up your game.

You can catch them on Iron Island once you have the National Pokedex. You get this by seeing all the Pokemon on the Sinnoh Pokedex.
You should go to a different website for that information becase this website should not have to give out hacking or illegal information. That's not hacking OR illegal information lol
I did the same thing and the only way that I found is to use the AR cheats to completely fill both the johto AND the national pokedex I'm not sure what it does if you just fill national but I would imagine it glitches.
It would be immpossible, because you can't get all the starters or legendaries. But for the rest of them, you would need time and lots of pokeballs.
