pal park with Pokemon ruby sapphire emerald fire-red and leaf-green. get the birth island cheat from supercheats.
you cant. But you can get it in peal and trade it to diamond.
well i think you have to trade it from Pokemon peal or the esiet way to do it is migrate tangella him or her from Pokemon leafgreen then evolve him or her into a tangrowth done.
Honchkrow was introduced during generation iv (diamond peal platinum heartgold soulsilver). so unfortunatly honchkrow cannot be obtained in fire red. Perhaps a nice ludicoldo instead
The Pokemon Victini, does not exist in any version made before Pokemon Black and White. Since it was released to catch in 2010(Japan) and 2011 (other places) it won't be able to caught in any other version before Black and White. Unless they made another event where you can catch Victini in other versions you could not catch it.
