You would have to but a flash card for the GBA and then put a hacked rom on the flash card to play.
No only if you have the hack version if you dont then no
No it cant.
You can only catch lugia if you migrated it from firered or leafgreen. If you want lugia get one from heartgold or soulsilver version.
hacks maybe
LeafGreen you can get Articuno, Zapdos, and Moltres, then you can catch Mewtwo. After that you can get Raikou(if your starter was Squirtle), Entei(if starter was Bulbasaur), or Suicune(if starter was Charmander). Lugia and Ho-oh can be found too, as well as a form of Deoxys
i dont know, im wondering the same thing bye!
lugia isn't in Pokemon leaf green
no.
Moltress Articuno Zapdos Mew Mewtwo Deoxys Lugia Ho-oh ; Entie,Suicune, or Raiku (depending on the starter)
You get it at Navel rock. Trade Ho-oh from Pokemon colosseum and trade lugia from Pokemon xd gale of darkness to leafgreen.
In The Navel Rock
Navel rock to get there you need a mystic ticket. Also you can trade the lugia from Pokemon xd gale of darkness to leafgreen.
