I don't think its possible without a action replay.
dig unerground for a fossil
the only way to get deoxys is: a)action replay/r4 b)migrating c)trading
Im afraid you cant.Deoxys an only be obtained by migrating or using a cheat device(gameshark,action replay ect.)
i did not catch deoxys without action replay it is really easy with action replay
Deoxys can only be obtained through migrating it from the Generation III Pokemon games or using the Action Replay to encounter it.
U HAVE TO MIGRATE OR ACTION REPLAY
There is no other possible way of getting suicune without migrating or action replay its a legendary anyway and you just get them for show
I don't think you can't.
you have to trade/migrate it from a different game that has a deoxys or buy a action replay
a while back they had an event at gamestop
there is a way...........trade
by migrating it you can get it in emerald i think
