I did this and i used an action replay for those Pokemon to appear in Mt.Moon (Leafgreen)
It is not possible to do.
lugia
the Pokemon emerald legendarys are: groudon kyogre rayquaza latias/latios deoxys (with aurora ticket) mew (with old sea chart) jirachi is possible to get but i don't know how lugia (mystic ticket needed) ho-oh (mystic ticket needed)
You can't.
if you want to do it without cheating you'll need a ticket to get to navel rock from a Nintendo event otherwise you can't get lugia without hacking or cheating unfortunately.
you need the mystic ticket and aurora ticket to go on island 8 and 9 mystic ticket takes you to navel rock, where you get a level 70 lugia and a level 70 ho-oh aurora ticket takes you to birth island,thats where you get a level 30 deoxys
Rayquaza, Kyogre, Groudon, Regiice, Regirock, Registeel, Lati(as/os)Of course Lugia, Ho-oh, Seribii, Deoxys, and mew are there. You need special event ticket to get them though.
Ho-oh, Lugia, Deoxys.
You can trade for them. That's all I can say.
Your best bet would be to trade. Ho-Oh = Pokemon Colliseum(sp?) Lugia = Pokemon XD: Gale of Darkness Deoxys = Nintendo Event i think.
there is no ticket to get lugia. if u fight the interviewer gabby about 14 times u get a lugia.*well dats wat i heard frm someone......
Mewtwo, Deoxys, Ho-oh, Lugia, and Mew(I think).
