You have to migrate the pokemon so any pokemon you have in your leafgreen can be in pal park but it disappears from your leafgreen
Not any hoenn Pokemon but firered and leafgreen can catch alot of kanto and johto Pokemon ruby and sapphire can and can't.
no
Any ghost type Pokemon can learn it.
of course
Any pokemon from Sapphire, Ruby, and LeafGreen
Any Pokemon game is fun and worth getting.
There are no cheats for ANY Pokemon games unless you have a gameshark
nothing use it as a Pokemon nothing to do with any events
Well what is your question
you can't catch any hoenn Pokemon in firered or leafgreen you must trade hoenn Pokemon from ruby or sapphire or emerald to leafgreen or firered.
Its not possible to capture any hoenn Pokemon in leafgreen if you want a roserade trade one from ruby, sapphire or emerald to leafgreen.
