It is an old event thats WAY gone
get the eon ticket and go to southern island
in pokemon emerald you can go to the two island next to the battle frontier
The souther island in emerald is in the southern part of the islands above it.
pokemon rock site
The Southern Island is the place you find the other Lati. You can go ther after you mix records with a R/S version that has the Eon Ticket.
in my pocket
Faraway island, Birth island and Southern island.
Its a place that you need the eon ticket to go to and in order to get that you have to go to a special Pokemon rock thing or whatever
ya dont

you can only warp to the southern island in Emerald version if that's what you meant. You'd need a Gameshark for Emerald version.
You probably mean southern island not southern cave because southern cave does not exist, southern island is an island you can only venture to on emerald and not ruby because of the eon ticket.
