Can we make an EON Ticket for Pokémon Ruby/Sapphire?

Follow for Part 2!!

In Pokémon Ruby, Sapphire, and Emerald, after the player receives the Eon Ticket from Norman and has entered the Hall of Fame, the first time they attempt to board the S.S. Tidal from the Lilycove City Harbor, a Sailor will replace the usual guide and offer to take the player to Southern Island.

The Eon Pokémon that did not roam Hoenn will appear on Southern Island: Latias in Pokémon Ruby, Latios in Pokémon Sapphire, and depending on the player's choice in Pokémon Emerald. The player battles the Legendary Pokémon in a standard stationary encounter; it does not appear as a roaming Pokémon and will not attempt to flee.

In Pokémon Ruby and Sapphire, the player cannot return to Southern Island after battling this Pokémon, regardless of the outcome of the battle. In Pokémon Emerald, the player can freely return to the island regardless of the battle's outcome.
