Code to unlock the old event tickets in emerald?

they're out there, but watch for the catch: a lot of the plain item codes just drop the ticket in your bag without setting the event flag, and then the sailor at lilycove ignores it. look for versions labelled as enabling the event rather than just giving the item, and make sure the code matches your cart's version and region. you also need to be past the league before the ferry will take you anywhere special, so don't panic if nothing happens on an early save. back up first, as always.
