when u fill the boxes int he computer
i only catch by now is 148 were i can catch more pokemon?
"How do you catch Professor Oak" You can't! He's a person NOT a pokemon. Possibly with the Action Replay
you can catch as many legendary Pokemon but only once unless you have it on the computer
You can catch Paris on some pokewalker routes, and in the viridian forest. (Possibly Ilex forest to.)
There are many Pokemon you catch that are similar in sapphire and emerald but there are many Pokemon emerald can only get and not sapphire.
I don't now but I believe that you can catch as many as you want when you encounter them.
Start by getting a lot of pokemon balls and then catch as many Pokemon as you can. Just catch Pokemon till you get to 200.
425
you don't need to catch them just see all the Pokemon in the hoenn pokedex
You can catch as much as you want.
I'm not sure about catch but in the Sinoh dex you can see 150 Pokemon
You can't possibly catch latios in Pokemon diamond although you may get it there by using your ruby version if you have one to import it to your diamond. another way is to buy an action replay and cheat
