How do you get luvdisc in emerald?
You fish for it at Ever Grande city after getting either the good rod or the super rod.
corsola is acctually one of the Pokemon you cant get in Pokemon emerald. sorry! actually...luvdisc can be found at the waterfall in ever grande city...don't go down the waterfall just the little pondish thing..you can also get a corsola there too! You can go down the waterfall. It doesn't matter where in route 128 you are, but you have to use a rod to get it.
