Lore
Thousands of years ago, a catacalsymic event upended the majority of the planet's landmass. Sea levels rose to drastic levels, forcing Pokémon and mankind alike into the formerly-high-altitude region of Keplara. Generations later, the region's ever-growing population would force humanity to encroach upon the feral Pokémon's territory, increasing tensions across the region. With no other land on Earth to populate, Keplara's human residents have begun to explore alternatives for human expansion. Some choose to explore the land or sea, but others turn their attention towards the stars and space-faring technology.

Story
You have lived your whole life in Andromeda City, the metropolitan heart of Keplara. Your father works for the Andromeda PD; your mother is the local Antares League gym leader. Someday you'll get a Trainer's License of your own and become a well-regarded Pokémon trainer yourself.
But today is not that day. Instead, today is an exciting day for Andromeda City: your mother's Antares League gym is moving into the snazziest new digs, all the way up to the top floors of the recently-completed Pokémon community skyscraper! There's still a few things left to move and unpack before the grand opening, but it's nothing that you and your father can't handle. What could possibly go wrong?

How to Play
Pokémon Voyager is a ROM hack of Pokémon Emerald. To play, you will need a Game Boy Advance emulator — we recommend mGBA — and a legally obtained ROM of Pokémon Emerald 1.0. You can follow Voyager's patch file here. If you have a tool to patch ROM files that you are comfortable with, then use it to apply the Pokémon Voyager patch to Pokémon Emerald. If you don't, you may use Hack64's web patcher. Here, you can select your Pokémon Emerald file as ROM, the patch file as the patch, have the patcher apply the changes and download a playable Pokémon Voyager ROM.

Frontier Demo
In addition to its original region and storyline, Pokémon Voyager also has quite a few custom battle mechanics and Battle Frontier facilities. This is a large undertaking for a small development team. In order to release incremental changes to our battle engine separately from the storyline, the Pokémon Voyager team has created a separate Frontier Demo patch for players to exercise the battle engine and provide incremental feedback on its quality and mechanics without waiting for the storyline to stabilize.
The Pokémon Voyager Frontier Demo is a standalone ROM which is created its own patch file which you can find here. Use your preferred method or follow the instructions above to apply this patch file to a legally-obtained copy of Pokémon Emerald.
You can read more about the Frontier Demo here.
