well if you use rom you can search pokemon (verson) rom cheats
You can only capture npcs pokemon
if you use a ds you cant
do you mean catch other peoples' pokemon? you can't.... not even with with a masterball!!!!
nope
not only can you not capture other peoples Pokemon, you will throw away a poke ball for nothing!you can only trade for other peoples Pokemon
You can use a Action Reply codes to catch other trainers pokemon.
You can usually catch others Pokemon by using a Master Ball(does not always work)
You can't, it's impossible!!
you have to use cheats from the game shark
YOU CAN'T CATCH OTHER PEOPLES POKÉMON. it's against the pokélaw:)
You can't if you try to its one pokeball wasted.
no it requires an action replay or any other cheating device to catch other people's Pokemon but i wouldn't recommend it because it can destroy your game
You can only get Kyogre through cheats, Pokemon Saphire, or a trade. Sorry but there's no other ways then that.
Not unless you have an action replay plugged into the back of your DS.
